What considerations should be taken into account when selecting key equipment for Shell’s powder coal gasification plant?
Thread Content
Dear colleagues in the marine industry, I would like to ask for your advice regarding the selection of key equipment in Shell’s powder coal gasification plants. In particular, I am interested in the considerations involved in choosing important devices such as the quench gas compressor K1301, medium-pressure high-temperature forced circulation pumps, vacuum belt filters, and slurry transfer pumps designed to handle slurries with high solid content. I would be extremely grateful if experts with relevant knowledge and experience could provide their guidance!
When selecting K1301, the following points should be taken into account: 1. The impeller and casing must be made of materials that are resistant to corrosion and erosion； 2. The sealing system should be of good quality; dry gas sealing is preferred ； 3. The temperature of the sealing gas at the innermost layer must be above 200 degrees
