Abstract
Отходящий газ (6) каталитически гидролизуют (1) и получают гидролизованный газ (15), содержащий HS и SOи свободный от COS и CS. После охлаждения (17), гидролизованный газ вводят в одну (2а) из двух каталитических зон Клауса (2а, 2b), собранных параллельно, при этом вторую каталитическую зону (2b) регенерируют, затем охлаждают. Регенерацию проводят за счет незамкнутой циркуляции потока газа (19, 36), отведенного от газа (15) перед его охлаждением (17), регенерационный газообразный эффлюент (24b) вводят (29, 20) в газ (15) между точками забора (19) и охлаждения (17). Охлаждение реактора (2b) осуществляют за счет незамкнутой циркуляции потока газа (11, 36), отведенного от газа (6), при этом газообразный эффлюент (24b) охлаждения вводят (29, 13) в газ (6) между точками забора (11) и нагревания (8).Международная заявка была опубликована вместе с отчетом о международном поиске.
