Description

Technical Field

[0001] The utility model belongs to the technical field of recovery, and in particular relates to a wharf oil and gas recovery device. Background Art

[0002] Oil and gas recovery at the terminal refers to the technology of collecting and treating the oil and gas generated during the loading and unloading process of the marine terminal to reduce environmental pollution and improve energy utilization. This technology can effectively reduce the impact of hydrocarbons on the environment and human health, while improving energy utilization efficiency and reducing production costs. Oil and gas recovery at the terminal generally includes three steps: collection, treatment and utilization. The collection methods include adsorption, condensation and combustion. The treatment process is mainly separation and purification to remove impurities and moisture to obtain high-purity hydrocarbons. Finally, the treated hydrocarbons can be used in equipment such as heating furnaces and generators in the production process, or sold and reused. The whole process will involve related oil and gas recovery equipment.
