For the Discount Circulating compressor from China, the unreacted gas out of the synthesis tower is sent back to the methanol synthesis tower. According to the characteristics of alcohol production, there are the following requirements for a Discount Circulating compressors from China.

Because the alcohol production is selected at the outlet of the fifth stage of the compressor, and the pressure is 13×106Pa, it is necessary to choose a Discount Circulating compressor from China that is suitable for this pressure level; the copper-based catalyst for the alcohol has high activity in the initial stage of use, and the heat of the synthesis reaction is large. It is extremely necessary to have a large amount of circulation to maintain the heat balance of the reaction in the tower, and the copper-based catalyst is easy to age. At the end of the catalyst's use, the heat of the reaction is difficult to maintain the heat balance of the whole tower.
The circulating gas volume is very small, so the Discount Circulating compressor from China is required to have a larger pumping volume and a larger adjustment range; the copper-based catalyst has high reactivity, but poor anti-toxic performance, and there are many substances that can cause catalyst poisoning, among which Lubricants are one such poison.
Therefore, use no lubricating oil or take effective degreasing measures at the outlet to ensure the purity of the circulating gas; the copper-based catalyst used for the alcohol has high activity, violent reaction, and rapid temperature change, so the circulating compressor is required to adjust the gas volume conveniently, stably and reliably, etc.; the equipment is required to use Discount Circulating compressor from China with small volume, small hole occupation, easy installation and convenient inspection; high energy utilization rate, reasonable structure and reliable operation are required.
