I. Product Overview
The absorption-based Vapor recovery unit is specialized environmental protection equipment designed to separate hydrocarbon components from Vapor mixtures using the principle of selective dissolution by an absorbent. The unit employs an absorption process operating at ambient temperature and pressure; a specialized absorbent (such as diesel, gasoline, or kerosene) is sprayed to capture VOCs from the Vapor stream. The enriched absorbent undergoes a desorption process to recover the hydrocarbons, while the tail gas is discharged in compliance with emission standards.
This product is widely used in high-throughput oil handling operations-such as oil depot loading racks, refining and chemical plants, and terminal loading/unloading facilities-serving as the core pre-treatment unit in combined adsorption-absorption systems.
II. Working Principle
Vapor enter from the bottom of the absorption tower and flow counter-currently against the absorbent (diesel, gasoline, or a specialized absorbent) sprayed from the top, interacting within the packing layer. Based on the principle of "like dissolves like," hydrocarbon components are dissolved and captured by the absorbent, while clean air is discharged from the top of the tower. The absorbent, now enriched with hydrocarbons, enters the desorption system; through heating or depressurization, the high-concentration hydrocarbons are released and recovered into storage tanks, while the regenerated absorbent is recirculated for reuse.
