改善从克劳斯法尾气中回收硫的系统和方法
Abstract:
降低SO2排放的系统包括氢化反应器、尾气冷却器、接触冷凝器、水解反应器和吸收器。所述氢化反应器被设置成接收克劳斯尾气并将所述克劳斯尾气中的至少一部分的SO2转化成H2S以产生经氢化的克劳斯尾气物流。所述水解反应器被设置成将至少一部分的COS转化成H2S。所述吸收器包含基于胺的溶剂并被设置成吸收至少一部分的H2S并将H2S再循环至克劳斯装置。
Abstract(English):

A system for reducing SO2 emissions comprises a hydrogenation reactor, a tail gas cooler, a contact condenser, a hydrolysis reactor, and an absorber. The hydrogenation reactor is configured to receive a Claus tail gas and convert at least a portion of SO2 in the Claus tail gas to H2S to produce a hydrogenated Claus tail gas stream. The hydrolysis reactor is configured to convert at least a portion of COS to H2S. The absorber comprises an amine-based solvent and is configured to absorb at least a portion of the H2S and recycle the H2S to the Claus plant.
