    摘要： A process and apparatus for removing excess carbon dioxide from a crude ammonia synthesis gas to be used for producing ammonia and urea, in which the incoming crude ammonia synthesis gas is separated into two streams. One stream is flowed into a scrubbing zone wherein it is contacted with a scrubbing solution so that the partial pressure of the carbon dioxide in the one stream leaving the scrubbing zone is in the range of about 0.02-1.5 atmospheres, under a total pressure of above about 10 atmospheres, at a temperature of about 85*-130* C. The other stream is not scrubbed. The two streams are then combined and are fed to an ammonia and a urea synthesis system. The amount of carbon dioxide removed is changed by adjusting the amounts of gas flowing in the two streams.

    摘要： In a circulating pressurized synthesis system, such as an ammonia synthesis system and a methanol synthesis system, a portion of the circulating stream of the circulatory synthesis system is separated from the circulating stream, fresh reactants are, if desired, added to the portion, and then the portion is compressed at least once to a pressure higher than that of the circulatory pressurized synthesis system. The compressed portion is passed through a synthesis reactor containing catalyst at high temperature so that a further reaction is promoted. The product obtained by the further synthesis reaction is separated from the effluent of the synthesis reactor, and, if desired, the energy which is generated by expanding the balance of the effluent to a pressure lower than that of the circulatory pressurized synthesis system is utilized to supply the power necessary to initially compress the portion.
