Explosion Proof Low Temperature Methanol Chiller For Oil and Gas Recovery System

Oil and gas recovery is a high-tech energy saving and environmental protection, the use of oil and gas recovery technology in oil storage and transportation, loading and unloading of emissions in the process of oil and gas, to prevent air pollution caused by volatile oil and gas, to eliminate potential safety problems, by improving the utilization of energy, reduce economic losses, resulting in considerable returns. At present, there are some common methods such as adsorption, absorption, condensation and membrane separation.

Here we talk about condensation method:
The heat transfer of oil and gas from the gas phase to the liquid phase is achieved by the use of refrigeration technology. Condensation method is the use of hydrocarbon substances at different temperatures of the vapor pressure difference, through the cooling of oil and gas to make some of the hydrocarbon vapor pressure over saturation state, supersaturated steam condensed into liquid, recovery of oil and gas. General multistage continuous cooling method to reduce oil and gas temperature, the condensed liquid recovery, according to the volatile gas components and recovery requirements and finally discharged to the concentration of organic compounds in the atmosphere in the exhaust limits, to determine the minimum temperature of the condensing unit. Generally according to pre cooling, mechanical refrigeration and other steps to achieve. The pre cooler is a single-stage cooling device, in order to reduce the operation energy recovery device, has developed a cold recycling technology, so that the inlet gas temperature recovery device from ambient temperature dropped to 4 degrees Celsius, make the most of water vapor in the gas condenses into water and remove. The gas enters the shallow cooling stage from the pre cooler. The temperature of the gas can be cooled to 30 DEG C - 50 DEG C, and the hydrocarbon material in the oil and gas can be recovered according to the requirement. The oil and gas from the shallow cold can enter into the cryogenic stage, and can be cooled to 73 DEG C to - 110 DEG C.
