And the principle? The 4th column of the low-temperature methanol wash unit can now operate with a single pump.
In low-temperature methanol washing, how is the cooling capacity calculated? How is the cooling load calculated?
1. There are mainly two types of cooling methods: ammonia cooling and propylene cooling； 2. Cooling principle: Gaseous ammonia or propylene is compressed by a compressor to liquefy it, and the resulting liquid is then sent to the methanol wash cryocooler. In the cryocooler, liquid ammonia or liquid propylene absorbs the heat from methanol, causing it to vaporize and thereby lowering the temperature of methanol. Gaseous ammonia or propylene gas is returned to the compressor inlet.
