用于处理来自硫回收系统的含硫废气的方法和设备
摘要：
本发明涉及用于回收硫(9)的方法以及设备，其中，在包括洗涤部件(SP)和再生部件(RP)的酸性气体洗涤设备(S)中，在循环洗涤剂(3)的辅助下，从粗合成气(2)选择性地除去硫组分和二氧化碳，并且将负载的洗涤剂再生期间产生的含硫气体部分(8)供应至硫回收系统(SR)，在所述硫回收系统(SR)中，形成包含二氧化碳以及硫组分的废气(10)，所述废气(10)被氢化(H)，并随后进行气体洗涤操作(Z)，其特征在于，从待处理的粗合成气(2)单独洗涤掉氢化废气(12)，其中从所述酸性气体洗涤设备(S)的洗涤剂回路除去的洗涤剂(13)用于洗涤掉硫组分。
摘要（英）：

The invention relates to a process and apparatus for recovering sulfur (9). In a sour gas scrubbing apparatus (S) comprising a scrubbing part (SP) and a regeneration part (RP), sulfur components and carbon dioxide are selectively removed from a crude synthesis gas (2) with the aid of a circulating scrubbing agent (3). A sulfur-containing gas fraction (8) produced during the regeneration of loaded scrubbing agent is supplied to a sulfur recovery system (SR) in which an off-gas (10) comprising carbon dioxide and also sulfur components is formed. The off-gas (10) is hydrogenated (H) and subsequently subjected to a gas scrubbing operation (Z). The hydrogenated off-gas (12) is scrubbed, independently of the crude synthesis gas (2), and scrubbing agent (13) removed from the scrubbing agent circuit of the sour gas scrubbing apparatus (S) is used to scrub out sulfur components from the hydrogenated off-gas (12).
