What are the reasons for catalyst loss in the oxychlorination reactor?
Thread Content
Our company uses large reactors with a capacity of 200 cubic meters to produce dichloroethane. During the reaction process, the catalyst is fluidized within the reactor; after separation using a cyclone separator, it is returned to the reactor. However, frequent loss of catalysts limits the production capacity. Please, all mages, discuss and help find the cause. Thank you!
The main issue is the poor performance of the separator; the key factor is the inlet flow velocity, as well as the ratio of the diameters of the inlet and outlet pipes
Regarding the issue of cyclone separation, we recommend that you contact the Institute of Chemical Engineering and Equipment at the Shanghai Institute of Chemical Technology for information. Phone number: 021-52815377. Note: This is not an advertisement in any way!
1# jiwzyj11: It is necessary to maintain the inlet flow rate; when the load is low, the reaction pressure should be reduced.
In addition to issues with the cyclone separator equipment, severe catalyst wear can also cause this phenomenon
