Conversion of catalytic cracking catalyst vacuum pump to water ring vacuum pump

2009-04-14View Original

Thread Content

The steam ejectors used in catalytic cracking units cause significant dust pollution; there are plans to replace them with water ring vacuum pumps. However, due to the old age of the existing ejector equipment, no relevant information is available. It is difficult to determine the appropriate flow rate for the water ring vacuum pumps, so I hope everyone can offer some advice! The pipeline for transporting the catalyst into the catalyst tank is DN150, and the catalyst addition rate should ideally be at least 1 ton per 40 minutes!
