Gas-liquid mixer

The gas phase consists of highly corrosive gases; the temperature is around 60 degrees, under atmospheric pressure, with a gas flow rate of about 400 cubic meters per hour. The absorption circulation fluid is an organic solvent at a temperature of around 110 degrees. I am looking for a Venturi-type gas-liquid mixer that can handle low vacuum conditions, high pumping capacities, as well as high temperatures and corrosion. I’m not sure which company can manufacture such a device; I hope colleagues can recommend some options.

The key to this situation is choosing the right material.
It has two names in the process package: it is called an atmospheric ejector in Chinese, and Gas Ejector in English. SIHI can do it
Taking the maximum operating temperature of 110°C into account, and considering whether resistance is needed to acid wash corrosion or alkaline corrosion, choosing the right material will do. There are many options available; those imported are expensive while domestic ones are generally cheaper. It is also recommended to conduct an ANSYS analysis to see how the simulation works, as it can be troublesome to redo such analyses if the product turns out to not work well.
Materials such as graphite, ceramic, and glass-lined steel are all acceptable; the main issue is finding a company that can design and manufacture it:
I don’t know what the corrosive agent is? At 60°C, plastics such as PP and PTFE can generally withstand this temperature ； If the pressure difference is high, use a liquid ejector; if it’s low, a liquid washer will suffice! The PP we have made, with alkali solution absorbing HCL ； PTFE+SS316L combination: Sodium thiosulfate for absorbing SO2. If needed, you can contact 15731758@qq.com
Search for Nantong Rose online and ask for information.
We can do it, but more parameters are needed... If you’re interested, you can send me an email at Jun.Li@screwvacuum.net
