Description

Technical Field

[0002] The condensation oil and gas recovery process is based on the basic thermodynamic properties of gasoline oil and gas components. It uses the difference in vapor pressure of hydrocarbon substances at different temperatures. By cooling, the vapor pressure of some hydrocarbons in the oil and gas reaches a supersaturated state, and the supersaturated oil and gas components undergo a phase change from gas to liquid to obtain liquid gasoline. The condensation method is the only way to complete the recovery of oil and gas in a one-time process, and it can see measurable recovered gasoline. For benzene vapor, since its boiling point is relatively high and its melting point is not very low, it is easy to achieve condensation recovery. Condensers are often used in the petrochemical industry to condense hydrocarbons and other chemical vapors. During the distillation process, the condenser converts the vapor into liquid, and all condensers operate by taking away the heat of gas or vapor.
