The business of Chengdu Sephing Technology Co., Ltd. mainly focuses on the purification and liquefaction of natural gas, pressure swing adsorption and membrane separation. It is a private enterprise of the same type in Chengdu with a good prospect, a relatively complete system, and a clear corporate structure and workflow. The project is sufficient, the workload is relatively large, and the income is ok, which is above average in Chengdu. There are experts among the staff.

I don't know much about Chengdu Tiancheng Carbon One, but my classmates have worked in it. There are not many projects, and the direction is single, mainly dimethyl ether. However, in recent years, the dimethyl ether market is depressed, and the project will not be too saturated. Technology is not as good as Cyprinus, and company structure and system are not as good as Cyprinus.
