1results about How to "Reduce refrigerant consumption" patented technology

The utility model discloses a system for increasing yield of light hydrocarbon by recovering hydrogen through a membrane method. The system comprises a heater, a membrane separator, a water cooler, a gas-gas heat exchanger, a condenser and a gas-liquid separator which are connected in sequence, a raw material gas pipeline is arranged at one end of the heater; a hydrogen product pipeline is arranged on the membrane separator; a light hydrocarbon product pipeline is arranged at one end of the gas-liquid separator. According to the application, the high-temperature-resistant membrane separator is used for recovering hydrogen on the permeation side, and meanwhile, a hydrocarbon dew point as high as possible is obtained on the non-permeation side, and when the hydrocarbon dew point is higher, the condensation recovery rate of downstream light hydrocarbon is higher; meanwhile, the high-efficiency recycling rate of hydrogen and light hydrocarbon is realized. In addition, the gas-gas heat exchanger arranged in the system can recycle cold energy, the load of the condenser and the use amount of the refrigerant are reduced, and therefore energy consumption is further reduced.
