How is carbon dioxide handled in the low-temperature methanol washing process?
Thread Content
In the low-temperature methanol washing process for water-coal slurry, how is the large amount of carbon dioxide handled?
It can be purified again to produce food-grade carbon dioxide, or it can be used for the development of downstream products such as urea and ammonium carbonate.
The temporarily designed process project does not involve the development of downstream products:
The temporarily designed process project does not involve the development of downstream products:
The reconstructed liquid nitrogen washing unit absorbs CO and then sends it to the urea production unit to produce urea
Sent to the urea production workshop, where ammonia reacts with carbon dioxide to produce urea
The reconstructed liquid nitrogen washing unit absorbs CO and then sends it to the urea production unit to produce urea. Wake up; stop sleeping.
CO2 is also a source of pollution in terms of environmental protection. A liquid CO2 system can be installed to produce liquid CO2
A few compressors are used to compress and liquefy the substance, which is then sold at low prices; the lowest price in the market is 200 yuan per ton
Main uses of carbon dioxide: 1. Producing food-grade carbon dioxide； 2. Produce urea ； 3. Produce methanol ； 4. Produce liquid carbon dioxide ； 5. Producing carbon dioxide resin ； 6. Produce dry ice ； 7. Produce soda ash ； 8. Produce high-purity carbon dioxide.
There are no downstream products that can be liquefied or used to produce dry ice.
