Process conditions for NHD desulfurization
Thread Content
What are the process conditions for producing 12.5W tons of dihydric alcohol using NHD desulfurization? What are the temperature and pressure levels?
The temperature is 40 degrees; the pressure depends on the operating pressure of your system!
Thank you. I also have a question: After Texaco produces gas, and the gas is cleaned of dust in a scrubber tower, does it need to be sent to a gas holder? What is the principle behind a gas holder?
What is the gas generation pressure? Generally, no gas holder is needed; after washing, the gas goes directly to conversion – desulfurization – decarburization
Temperature 1400 Pressure 4MPA
NHD has selective absorbance. The desulfurization temperature is 24 degrees, and the decarburization temperature is -7 degrees; the lower, the better. The gas phase pressure is generally medium pressure, 3–4 MPa
The Selexol process: 40 degrees of desulfurization, 7 degrees of decarburization; increasing the pressure helps to improve the purity of the useful gas.
