The necessity of oil and gas recovery:
With the deterioration of the global environment and the increasing awareness of environmental protection, China has successively introduced a series of environmental protection policies, which mandate the installation of oil and gas recovery systems to recycle and utilize the volatile oil and gas from storage tanks, loading and unloading vehicles, ships and other transportation facilities, in order to prevent air pollution.
Principle of Condensation Adsorption Technology:
The combination of condensation and adsorption process first condenses the oil and gas to -75 ℃ (which can be cooled in three stages). Alkanes above C3 are basically condensed and recovered, with a recovery rate of 80-90%. The remaining small amount of alkanes are adsorbed and recovered in the adsorption system, and after adsorption, qualified and compliant air is discharged; After detachment, a small amount of oil and gas returns to the system inlet for circulation. The recovery rate can reach over 97%. The setting of refrigeration temperature is designed and formulated according to different working conditions.
Application scope of condensation adsorption method:
1. Oil and gas recovery system for refined oil tank trucks in refineries and oil storage depots
