Components at the vacuum pump outlet of the vacuum flash evaporation system
Thread Content
The gas exiting the vacuum pump of the vacuum flash evaporation system contains trace amounts of CO, H2, CO2, H2S, etc. The gas composition specified by the design institute varies greatly; has anyone who is working on the gasification site actually carried out analyses? What are the specific components? Please help answer it, thank you.

It’s true that there are differences; if the type of coal used is different, the design pressure differs, or the number of flash stages varies, then the gas components in vacuum flash evaporation should also differ. Therefore, it’s impossible for the gas components in all flash evaporation systems to be identical. The best approach is to use similar types of coal, analyze the gas components based on actual operation conditions, and then use these data to convince the patent holder of the process package to verify whether the data is accurate – rather than turning to design firms. It is understood that few design firms currently possess proprietary technology for coal gasification processes (except for pressurized coal gasification); design firms are only responsible for optimizing the design of the process package, while the components of the flash gas are determined based on the material balance sheet of that process package.
As mentioned above, the design institute provides data from the process package, all of which are derived through calculations. Since these are trace components, I assume that the patent holders will not adjust the process package based on actual measurements taken on site. (The components of the crude syngas are handled in this way).
So, to know the actual components on site, we need the guys from the factory to answer
