What is the temperature after the interstage cooling of the rich gas compressor? ?
Thread Content
Catalytic cracking rich gas compressors generally use multi-stage or multi-stage compression, so there is inter-stage intermediate cooling. What cooling medium is generally used for this inter-stage cooling (air cooling or water cooling), and what is the temperature after cooling? ? ? ?
Air cooling requires a large investment and occupies a large area. Water cooling can meet the requirements. Generally, the cooling is lower than 40 degrees and the liquid can be separated from the gas.
Generally, the water cooling temperature is usually around 45 degrees to prevent the cooler from scaling.
Water cooling, generally cooling below 45 degrees
At present, water cooling is mostly used, and circulating water is used for cooling. Due to the water temperature limit, it is about 40 degrees.
The interstage coolers of catalytic device compressors are generally water-cooled. It seems that I have never seen the air-cooled ones used at home! Generally, the temperature after cooling is around 40°C.
Catalytic rich gas compressors are generally selected based on the device. Most of them are 2-stage 5-stage or 6-stage variable compression! Most of the intercoolers are water-cooled! I haven’t heard of air cooling! Generally, cooling to about 40 degrees is enough!
