Which process technology is available at home and abroad for purifying crude syngas from coal gasification? The first phase of our factory uses Lurgi's low-temperature methanol washing technology. What I would like to ask is, in addition to Lurgi's technology, what other mature and reliable technologies are there in foreign countries? In addition, if there is also mature and reliable machinery in China, please let me know. Thank you!
Syngas purification includes many methods, including the original hot alkali washing, tannin method, NHD method, low-temperature methanol washing (Dalian Ligong), LINDER low-temperature methanol washing, Lurgi low-temperature methanol washing, etc. Nowadays, the NHD method, low-temperature methanol washing (Dalian Ligong), LINDER low-temperature methanol washing, and Lurgi low-temperature methanol washing are commonly used. Among them, the one with the smallest energy consumption is low-temperature methanol as the absorbent. Of course, I have not compared different low-temperature methanol washing processes.
Low-temperature methanol washing (Dalian University of Technology), LINDER low-temperature methanol washing, and Lurgi low-temperature methanol washing. What are the differences between these three processes? You can compare from many aspects such as process details, energy consumption, materials, operations, etc.! b] 2# Modern Prince
Shanghai International Construction can also provide low-temperature methanol washing technology. Yitai's coal-to-liquid production uses their technology, which is no worse than that of Dalian.
