Imported equipment in coal chemical industry
Thread Content
I would like to ask the experienced members of this forum: are there any devices in the coal chemical or petrochemical industries that must be imported entirely? ?
It would be better to specify a particular device; this is too general
Speaking specifically of the gas chemical processing section, although domestic options are available, high and low pressure slurry pumps as well as high pressure nitrogen compressors still require imported models due to their better reliability.
Let’s look at the budget. To be honest, foreign products are still better, more refined.
Things like gasification furnaces and advanced processes all require imports
It is mainly the process package; in terms of equipment, domestic options are basically sufficient.
We have a 500,000-ton Texaco gasifier; the imported equipment includes high-pressure coal slurry pumps (from Chihao), low-temperature pumps for methanol purification (from United Pump Industry), and some key control valves are also imported (such as oxygen valves). The catalysts used for conversion (the brand is kept confidential); everything else seems to be of domestic manufacture.
The small screw in the gasifier. . Haha
