What kind of sulfur injection pump is used for wet vulcanization?
Thread Content
Should a reciprocating pump or a centrifugal pump be used? What size should it be? How to make the choice? Is a reciprocating pump suitable?
Reciprocating pump, low flow rate, high head
Reciprocating diaphragm, with adjustable volume as well
The choice of pump has nothing to do with whether the process is wet or dry; what was said above is completely correct – reciprocating, plunger, and diaphragm metering pumps can all be used.
The main factor in deciding between a reciprocating pump or a centrifugal pump is the amount of sulfur to be injected; in wet sulfiding processes, the point where sulfur is injected is usually located before the feed pump, and a lower pressure at the pump outlet is required, so the head requirement is relatively low. For units with a large catalyst loading, a centrifugal pump can be selected as the sulfur injection pump.
It’s simpler here; we use a pressure tank to fill it with nitrogen, and then the vulcanizing agent is injected at the inlet of the raw material pump.
The reciprocating pumps we use are mainly chosen for their ease of flow control
This device does not require a pump; instead, a nitrogen line is installed at the top of the vulcanizing agent tank to apply pressure, with the pressure being used to push the material into the feed oil line
A regular auxiliary reciprocating pump will suffice.
