摘要： A method for treatment of process condensate (1) in an ammonia plant, wherein the ammonia plant comprises a front-end section producing a make-up gas and a synthesis section where the make-up gas is reacted to ammonia, and said process condensate (1) is collected from one or more equipment of the ammonia plant and is an aqueous solution comprising ammonia, carbon dioxide and methanol. Said method comprises: stripping said process condensate with low-pressure steam (4), obtaining a vapour phase (5) comprising ammonia, carbon dioxide and methanol stripped from the process condensate; condensing said vapour phase, obtaining a solution (11) enriched of ammonia and methanol (11); re-introducing a first portion (12) of said solution to said stripping environment; recycling a second portion (13) of said solution to said ammonia plant.

摘要： A method for recovering waste heat in a process for the synthesis of a chemical product, particularly ammonia, where the product is used as the working fluid of a thermodynamic cycle; the waste heat is used to increase the enthalpy content of a high-pressure liquid stream of said product (11), delivered by a synthesis section (10), thus obtaining a vapour or supercritical product stream (20), and energy is recovered by expanding said vapour or supercritical stream across at least one suitable expander (13); the method is particularly suited to recover the heat content of the syngas effluent after low-temperature shift.

摘要： The invention relates to a method for carrying out heterogeneous catalytic exothermic gas phase reactions at a high temperature and high pressure, during which the synthesis gas comprised of a mixture of make-up gas and/or of recycle gas is led through at least two synthesis stages that are connected in-series to form a synthesis system. The product gases from the synthesis stages, with the exception of the last stage, are separated into at least two partial flows. One partial flow is cooled until the product is condensated out, and the condensate containing the product is separated from the gaseous constituents. Afterwards, the gaseous constituents are combined with the warm portion of the product gas in order to reach the inlet temperature of the next synthesis stage. In addition, the partial flow, from which the product was condensated out and removed, can be heated before being remixed with the warm portion of the product gas. After heating, the temperature is less than that of the warm portion of the product gas, and the heat used for heating the partial flow, from which the product was condensated out, is extracted, at least in part, from this partial flow during its cooling.
