摘要： The invention relates to ammonia synthesis loops containing gases, which do not react and would accumulate if they were not purged out. By the present invention ammonia in a purge gas is recovered by an absorption agent operating at the full synthesis loop pressure. The absorption agent is chosen in such a way that the ammonia can be removed again by passing a gas comprising hydrogen and nitrogen through it at the same elevated pressure as the loop pressure. This enables the adsorption agent to be regenerated by fresh synthesis gas coming from the synthesis gas compressor just before this gas enters the synthesis loop. Thereby, the regeneration requires an absolute minimum of energy consumption and equipment.
摘要翻译：本发明涉及含有气体的氨合成回路，如果它们没有被排出，其不起反应并且会积聚。通过本发明，净化气体中的氨通过在完全合成回路压力下操作的吸收剂回收。吸收剂的选择方式是通过在与环路压力相同的高压下通过包含氢气和氮气的气体再次去除氨。这使得吸附剂能够在该气体进入合成回路之前由来自合成气压缩机的新鲜合成气再生。因此，再生需要绝对最小的能量消耗和设备。

摘要： A description is given of agglomerates of faujasite X with an Si/Al ratio of 1, the inert binder of which, on the one hand, has been converted to active zeolite by conversion to zeolite in an alkaline liquor, and which have been subjected, on the other hand, to an exhaustive lithium exchange. These adsorbents develop a nitrogen adsorption capacity (1 bar/25° C.) of at least 26 cm3/g, which makes them excellent adsorbents for the non-cryogenic separation of gases from air and for the purification of hydrogen.

摘要： A gas separation apparatus and process has a first pressure swing adsorption (PSA) unit (110) receiving feed gas (112), which comprises a first and a second component. First PSA unit (110) produces first product gas (114) pre-dominantly containing the first component, and first off gas (116) containing at least some of the first component and second component. Compressor (120) is coupled to first PSA unit (110) to compress first off gas (116) to form compressed off gas (126), which is passed downstream to absorber unit (130), which employs a solvent to remove at least part of the second component from compressed off gas (126), forming an enriched compressed off gas (136B). Second PSA unit (140) receives enriched compressed off gas (136B) and produces second product gas (142) which predominantly contains the first component and a second off gas that is sent to waste or reformer burner (150).
