There are usually six such heat exchangers, namely the feed gas cooler, the circulating methanol cooler, the methanol heat exchanger, the first lean methanol cooler, the second lean methanol cooler, and the third lean methanol cooler.

In addition to what you mentioned above, the lean methanol pump, the feed pump for the carbon dioxide desorption tower, the methanol pump in the hydrogen sulfide concentration tower, the feed pump for the thermal regeneration tower, the feed pump for the methanol-water separation tower, and the flash vapor compressor are also very important.

There are many key equipment units, such as: five towers, raw material gas cooler, circulating methanol cooler, methanol heat exchanger, first lean methanol cooler, second lean methanol cooler, and third lean methanol cooler. Recycle compressors, methanol pumps, etc.
