Title:
METHOD AND SYSTEM FOR PURIFYING SYNTHESIS GAS, IN PARTICULAR FOR AMMONIA SYNTHESIS
Document Type and Number:
WIPO Patent Application WO/2014/008996
Kind Code:
A3
Abstract:
The invention relates to a method for purifying synthesis gas, in particular for ammonia synthesis, wherein a partial stream (26) of an H2-rich, CO-containing synthesis gas stream is burned, in particular to generate electrical energy, and wherein at least one component contained in the remaining H2-rich, CO-containing synthesis gas stream (26a), in particular in the form of carbon dioxide, methanol and/or water, is absorbed by an adsorber at low temperatures, after which said absorbed component is desorbed from the adsorber by flushing using nitrogen (33) at higher temperatures. According to the invention the H2-rich partial stream (26) is diluted using the nitrogen (35) used for the flushing before being burned. The invention further relates to a system (1) for purifying synthesis gas, in particular for ammonia synthesis.
