Discussion on natural gas dehydrogenation

2025-11-04View Original

Thread Content

25,000 Nm3 of natural gas per hour enters the low-temperature condenser for hydrocarbon removal; the condensation temperature for this process is -30 degrees. Three hydrocarbon removal adsorption towers are installed after the low-temperature condenser, and the regeneration gas from these towers is also condensed simultaneously. Propane is used as the refrigerant. What capacity is required for refrigeration? With a condensation temperature of 45 degrees and an evaporation temperature of -33 degrees, what motor power should be selected for the propane-based screw compressor in order to handle 25,000 Nm3 of natural gas per hour?
