This invention relates to a process for the production of power while using liquefied natural gas LNG and synthesis or fuel gas. Liquefied natural gas LNG is generally brought in by tanker from remote sites and traditionally regasified by heat exchange with sea water. A single multi-component motive fluid was used as the liquefied natural gas exchange media in U.

Raw synthesis gas, substantially comprising mixtures of H 2 , CO, CO 2 , N 2 , H 2 O, H 2 S and COS, as produced from sulfur-containing fossil fuels by contemporary partial oxidation processes, may have a methane content in the range of about nil to 2 mole percent and a maximum net heating value of about BTU per standard cubic foot SCF. In some applications, it is desirable to increase the methane content of the synthesis gas, for example to increase its gross heating value for use as fuel gas.

In coassigned U. Costly removal of water from the product gas was necessary. In comparison with the prior art, by the subject invention a dry, sulfur-free, CH 4 -enriched synthesis or fuel gas is produced without costly catalytic methanation or drying steps. The present invention involves an improved continuous process for the production of power while using liquefied natural gas LNG or CH 4 -enriched sulfur-free synthesis gas as fuel.

The gaseous fuel is burned in a combustor, which discharges exhaust gas. The thermal efficiency of the process is greatly increased by extracting the heat from the exhaust gas by heating various streams in the process and optionally vaporizing LNG. The vaporized LNG is introduced into a pipeline for distribution to residential and industrial users.

It is also mixed with synthesis gas to produce methane-enriched synthesis gas for use as fuel gas in the integrated combustion turbine. For additional information, reference is made to coassigned U. Depending on their chemical compositions, gaseous mixtures made by the partial oxidation process are referred to as synthesis gas, reducing gas, or fuel gas.

Before cleaning and purification they may contain a small amount of particulate matter and sulfur containing gases. Synthesis gas substantially comprises H 2 and CO in various ratios. Reducing gas is rich in H 2 and fuel gas contains greater amounts of CH 4. Heat-containing streams are defined herein as a gaseous or liquid stream as produced in the process for the partial oxidation of gaseous or liquid hydrocarbonaceous fuels or solid carbonaceous fuels including pumpable slurries of solid carbonaceous fuels for the production of synthesis gas, reducing gas, or fuel gas e.

Included also are the heat containing streams from steps associated with the partial oxidation process including gas cooling, cleaning, and purifying; as well as the air stream for preparing oxygen for use in the partial oxidation gasifier.

Advantageously, low level energy normally rejected from the partial oxidation process may now be used to assist in warming or vaporizing the LNG thus improving the thermal efficiency of that step. Further, the expensive and energy consuming sea water pump normally used to provide sea water as a source of energy to vaporize LNG may now be eliminated. The heat containing streams are selected from the group consisting of:. A more complete understanding of the invention may be had by reference to the accompanying schematic drawing which shows several embodiments of the process in detail.

Liquefied natural gas LNG from cryogenic storage 1 at a pressure in the range of about 0. The pressure of the LNG in line 4 is thereby increased to a pressure in the range of about 40 to atmospheres by pump 3.

It is more economic to elevate the pressure of LNG by pumping it as a liquid in comparison with compressing it as a gas. The LNG in line 4 is split into two portions: a the LNG in manifold lines to be used as an indirect coolant for heat exchangers 8 to 11, and b the LNG in manifold lines 18 to 22 to be used as an indirect coolant for various heat exchangers in the partial oxidation gasification plant e.

Advantageously, the use of cold liquefied LNG to cool the air entering air separation unit ASU 16 will improve the thermal efficiency and reduce the capital and operating costs of the ASU. The air is passed through heat exchanger 32 which is thermally coupled to heat exchanger 8 by a loop containing inert coolant e. This is a safety measure to prevent LNG from contacting air should there be a leak in the lines. The LNG in liquid phase is passed through lines 4, 5, 34, and heat exchanger 8 where it may be warmed to a temperature up to about Vaporized or liquid LNG leaves exchanger 8 through line 35 and is passed through interstage air cooler 9 which is thermally coupled to heat exchanger 36 by a loop containing inert coolant e.

Liquid LNG passes through heat exchanger 9 where it may be warmed to a temperature up to about The physical state of the LNG after heat exchange depends upon such factors as initial temperature and pressure of the LNG, temperature of heat exchange fluid, and design of heat exchanger.

The vaporized LNG passes through manifold pipe 38, lines 54, 44, valve 39, and pipes 17, 40 to 42 to a pipeline for distribution to gaseous LNG consumers. The inert gas e. The air in line 31 is compressed in a number of stages in air compressor 43 with a cooling step included between each stage to improve compressor efficiency. Cooling of one typical interstage is effected by heat exchangers 9 and 36 with coolant loop Hot partially compressed air is removed from compressor 43 through line 45, cooled in heat exchanger 36 by heat exchange with nitrogen in loop 37 and returned to compressor 43 for additional compression by way of line The warm N 2 in loop 37 is cooled in heat exchanger 9 by indirect heat exchange with LNG from line While only one interstage cooler is shown and described, it is understood that similar interstage coolers may be used for cooling the compressed air passing between the plurality of stages in a multi-stage air compressor.

The temperature and pressure of the air in lines 46 and 47 are substantially the same. The remainder is air from line The air in line 48 is further cooled in heat exchanger 49 with an inert coolant gas, such as nitrogen, passing through refrigeration loop coil 50 which in turn is cooled in heat exchanger 10 by LNG from line The inert coolant gas is used as a safety device for the same reason as previously mentioned.

The LNG in heat exchanger 10 is vaporized and leaves through lines 52, 53 and passes through vaporized LNG manifold pipe 54, valve 39 and pipes 40 to 42 to a pipeline for distribution to vaporized LNG consumers. For additional description of air separation units, see Kirk-Othmer Encyclopedia of Chemical Technology, Third Edition, Pages to , which is incorporated herein by reference. At a pressure in the range of about 5 to psia, above the gasifier inlet pressure the oxygen gas is passed through line 60 and burner 61 located in the top of gasifier 57 and extending downward into the upper inlet along the central axis of gasifier Partial oxidation gas generator 57 is a free-flow unobstructed down-flowing vertical refractory lined steel wall pressure vessel where the partial oxidation reaction takes place.

A typical gas generator is shown and described in coassigned U. Another scheme providing cooling the hot raw effluent gas stream in a radiant cooler followed by a waste heat boiler is shown in the drawing for coassigned U. A three or four stream annular type burner, such as shown and described in coassigned U. With respect to U. It is used for improved combustion efficiency and to prevent nitrogen from air from diluting the product gas.

The fuel feed comprising for example an aqueous slurry of solid carbonaceous fuel e. A wide range of combustible carbon containing organic materials may be reacted in the partial oxidation gas generator with a free-oxygen containing gas optionally in the presence of a temperature moderating gas to produce a raw stream of synthesis or fuel gas.

The term hydrocarbonaceous as used herein to describe various suitable feedstocks to the partial oxidation gas generator is intended to include gaseous, liquid, and solid hydrocarbons, carbonaceous materials, and mixtures thereof. In fact, substantially any combustible carbon containing organic material, fossil fuel, or slurries thereof, may be included within the definition of the term "hydrocarbonaceous. The hydrocarbonaceous fuel may have a sulfur content in the range of 0 to 10 weight percent and an ash content in the range of about 0 to 50 weight percent.

The term liquid hydrocarbon or liquid hydrocarbonaceous fuel as used herein to describe suitable liquid feedstocks, is intended to include various materials, such as liquefied petroleum gas, petroleum distillates and residues, gasoline, naphtha, kerosine, crude petroleum, asphalt, gas oil, residual oil, tarsand oil and shale oil, coal derived oil, aromatic hydrocarbon such as benzene, toluene, xylene fractions , coal tar, cycle gas oil from fluid-catalytic-cracking operation, furfural extract of coker gas oil, tire oil and mixtures thereof.

Gaseous hydrocarbon fuels, as used herein to describe suitable gaseous feedstocks, include methane, ethane, propane, butane, pentane, natural gas, water-gas, coke-oven gas, refinery gas, acetylene tail gas, ethylene off-gas, synthesis gas, and mixtures thereof.

Both gaseous and liquid feeds may be mixed and used simultaneously, and may include paraffinic, olefinic, naphthenic, and aromatic compounds in any proportion. Also included within the definition of the term hydrocarbonaceous are oxygenated hydrocarbonaceous organic materials including carbohydrates, cellulosic materials, aldehydes, organic acids, alcohols, ketones, oxygenated fuel oil, waste liquids and by products from chemical processes containing oxygenated hydrocarbonaceous organic materials and mixtures thereof.

The hydrocarbonaceous feed may be introduced into the burner in liquid phase or in a vaporized mixture with a temperature moderator. Suitable temperature moderators include steam, water, CO 2 -rich gas, nitrogen in air, by product nitrogen from a conventional air separation unit, and mixtures of the aforesaid temperature moderators.

The use of a temperature moderator to moderate the temperature in the reaction zone depends in general on the carbon to hydrogen ratio of the feedstock and the oxygen content of the oxidant stream. A temperature moderator may not be required with some gaseous hydrocarbon fuels, however, generally, one is used with liquid hydrocarbon fuels and with substantially pure oxygen.

The temperature moderator may be introduced in admixture with either or both reactant streams. Alternatively, the temperature moderator may be introduced into the reaction zone of the gas generator by way of a separate conduit in the fuel burner. The preferred temperature moderator is H 2 O. The burner assembly 61 is inserted downward through a top coaxial inlet port in the noncatalytic synthesis gas generator The burner extends along the central longitudinal axis of the gas generator with the downstream end discharging a multiphase mixture of fuel, oxygen gas, and temperature moderator e.

H 2 O directly into the reaction zone. The relative proportions of solid, liquid, or gaseous fuels, water and oxygen in the feedstreams to the gas generator are carefully regulated to convert a substantial portion of the carbon in the fuel e.

The pressure in the partial oxidation reaction zone is in the range of about 1 to atmospheres. The weight ratio of H 2 O to carbon in the feed is in the range of about 0.

The dwell time in the reaction zone is in the range of about 1 to 10 seconds, and preferably in the range of about 2 to 8 seconds. Unconverted carbon, ash, or molten slag are contained in the effluent gas stream. Depending on the composition and use, the effluent gas stream is called synthesis gas, reducing gas, or fuel gas.

Coal has a high ash content e. The slag will flow from the reaction zone of the gas generator as substantially inert molten slag and be quenched in quench water 62 at the bottom of gasifier Periodically, the slag will be removed by way of a slag hopper not shown and line 63, valve 64, and line Also, hot syngas in transfer line 66 may be cooled by indirect heat exchange for example with water from line 67 to produce steam in line 68 in gas cooler The cooled gas stream in line 70 is scrubbed with water in scrubber Water enters scrubber 71 through line 99 and water and particulate matter leave from the bottom through line 72, valve 73, and line The coolant may be LNG or water.

The cooled gas enters knockout pot 76 by way of line Condensed water is removed from pot 76 through line 77, valve 78, and line There it is cooled by indirect heat exchange with liquid LNG from line Water collects in the bottom of knockout pot and is periodically drained through line , valve and line Optionally, when additional cooling of the synthesis or fuel gas stream is required, for example for improved operation of acid-gas absorber , LNG in liquid phase is passed through lines 21 and , valve , line and mixed in line 29 with the stream of synthesis or fuel gas from line Cold lean, liquid acid-gas absorbent solvent such as monoethanolamine MEA , diethanolamine DEA , triethanolamine TEA , diisopropanolamine, or methanol is introduced through line near the top of absorption column As the raw syngas passes up column it makes contact with the liquid absorbent solvent passing down the column.

Depending on the type of liquid solvent, substantially all of the H 2 S, residual moisture, and COS in the synthesis gas is absorbed by the solvent. In such case, most of the CO 2 remains in the synthesis or fuel gas stream that is burned in combustor The SO x content in the exhaust gases in line 82 is thereby substantially reduced.

Rich absorbent solvent is removed through line , valve , and line and sent to a solvent regeneration unit. The regenerated lean absorbent solvent is then introduced into acid gas absorber by way of line

Сон принадлежал миру ночи и дня, здесь же был только день. Его транс был ближайшим возможным приближением к этому позабытому состоянию, способным - он знал это - помочь собраться с Он узнал не так уж много нового для себя: почти обо всем, сообщенном Джезераком, он так или иначе успел догадаться заранее.

Но одно дело догадываться, совсем другое - получить неопровержимое подтверждение догадок. Как отразится это на его жизни и отразится ли.

Элвин не был уверен ни в чем, а неуверенность для него была вещью необычной. Возможно, никакой разницы не будет: если он не сможет полностью приспособиться к Диаспару в этой жизни, он сделает это в следующей - или в какой-либо из дальнейших.

Но не успев додумать эту мысль, разум Элвина отверг. Пусть Диаспар достаточен для всего остального человечества. Для него -. Да, он не сомневался, что и за тысячу жизней не исчерпать всех чудес города, не испробовать всех возможных путей бытия.

Он мог бы заняться этим, но никогда не получит удовлетворения, пока не совершит нечто более значительное.

И еще он подумал об Алистре. Она любила его, а он то принимал, то отвергал ее любовь -- по своей прихоти. Быть может, откажись он от нее совсем, она стала бы хоть ненамного счастливее. Теперь он понимал, почему никогда не испытывал по отношению к Алистре ничего похожего на любовь -- ни к ней, ни к какой-нибудь другой женщине в Диаспаре. Это был еще один урок из тех, что преподал ему Лиз.

Диаспар многое забыл, и среди забытого оказался и подлинный смысл любви. В Эрли он наблюдал, как матери тетешкали на руках своих малышей, и сам испытал эту нежность сильного, нежность защитника по отношению ко всем маленьким и таким беспомощным существам, которая есть альтруистический близнец любви.

А вот в Диаспаре теперь не было уже ни одной женщины, которая знала бы или стремилась бы к тому, что когда-то являлось венцом любви. В бессмертном городе не было ни сильных чувств, ни глубоких страстей. Вполне возможно, подобные чувства могли расцвесть только в силу своей преходящести, ибо не могли длиться вечно и всегда были угнетены той тенью неизбежности, которую Диаспар уничтожил.

Вопросы, которые он задавал, были так терпеливы, он говорил с таким участием и в то же самое время с такой настойчивостью и убедительностью, что Олвин решил ни в коем случае не прерывать его, хотя его так и подмывало вступить в разговор.

Ему не хотелось признаваться себе, что Хилвар превосходит его по развитию, но не было ни малейших сомнений в том, что дар друга общаться с животными простирается даже на это фантастическое существо. И более того -- чудище, похоже, откликалось. Его речь стала более разборчивой, и если сначала это странное создание отвечало столь кратко, что выходило чуть ли не грубо, то, по мере того как развивалась беседа, оно стало отвечать на вопросы подробно и даже само уже сообщало кое-какую информацию, о которой его и не спрашивали.

Хилвар терпеливо складывал по кусочку мозаику этой невероятной истории, и Олвин совсем потерял ощущение времени. Всей истины они выяснить так и не смогли -- для догадок и предположений оставалось места сколько угодно.

Теперь он понял, что Хилвар был совершенно прав, доставив Ванамонда в Лис. К тому же он оценил, насколько повезло ему самому, когда он сумел перехитрить Серанис: совершить подобное еще раз ему, конечно, никогда бы не удалось.

Через несколько часов мы будем знать истину. "Мы будем знать истину". Может быть и так, - подумал Элвин, - но какая ее часть нам в принципе доступна.

Удивительно, но именно сейчас, покидая Диаспар и саму Землю с невообразимой скоростью, он мыслями вновь устремился к тайне своего происхождения.

Я привел его сюда на встречу с Центральным Компьютером. Это спокойное заявление заметно смутило служителей Совета.

Но это, по крайней мере, стоило совершить, чтобы утолить душевную тоску. Словно в нежелании возвращаться в обычный мир, Элвин задержался среди отражений прошлого. Стоя перед одним из огромных зеркал, он наблюдал за сценами, появлявшимися и исчезавшими в его глубинах.
