Product Name: Oil & Gas Vapor Recovery Unit (VRU)
Technology: Adsorption + Desorption + Absorption Hybrid System
Keywords: Vapor Recovery, VOC Emission Control, Oil & Gas Recovery, Solvent Recovery, Environmental Compliance, Carbon Adsorption

Product Overview

Maximize resource recovery and minimize emissions with our Adsorption-Desorption Absorption Oil and Gas Recovery Equipment. This advanced hybrid system integrates the high efficiency of activated carbon adsorption with the stability of liquid absorption (oil scrubbing) to capture and recover valuable hydrocarbons from gas streams.

Designed for the petroleum and petrochemical industries, this equipment treats vapors generated during loading, unloading, and storage operations. The process involves adsorbing organic vapors onto a carbon bed, followed by vacuum or steam desorption to concentrate the vapors, which are then absorbed into a lean oil or solvent stream. This ensures high recovery rates (>99%) of valuable commodities like gasoline, crude oil, and solvents, while ensuring strict compliance with environmental regulations.

Key Advantages

• High Recovery Efficiency: Achieves emission levels below 10g/m³, recovering valuable hydrocarbons that would otherwise be lost to the atmosphere or flaring.
• Safety & Stability: The absorption stage acts as a buffer, preventing the formation of explosive mixtures and ensuring stable operation even with fluctuating inlet gas concentrations.
• Energy Efficient: Utilizes vacuum desorption and heat exchange systems to minimize energy consumption during the regeneration cycle.
• Automated Operation: Fully integrated PLC control system manages valve switching, pressure regulation, and temperature monitoring, allowing for unattended 24/7 operation.

Technical Specifications

Working Principle

1. Adsorption: Contaminated gas passes through a bed of high-efficiency activated carbon. Organic vapors (VOCs) are trapped in the carbon pores, while clean air is vented.
2. Desorption: Once the carbon bed is saturated, a vacuum pump or steam is used to desorb the concentrated hydrocarbons from the carbon.
3. Absorption: The concentrated hydrocarbon stream is introduced into an absorption tower where it contacts a counter-current flow of lean oil (or absorbent). The hydrocarbons dissolve into the oil.
4. Separation: The rich oil is sent to a distillation or separation unit to recover the pure product, while the lean oil is recycled back to the absorption tower.

Applications

• Oil Depots & Terminals: Recovering gasoline and diesel vapors during tanker truck and railcar loading operations.
• Refineries & Petrochemical Plants: Treating emissions from storage tanks, wastewater treatment units, and process vents.
• Marine Loading: Controlling emissions during the loading and unloading of crude oil and chemical tankers at ports.
• Chemical Manufacturing: Recovering solvents like benzene, toluene, and xylene from production processes.

Packaging & Storage

• Configuration: Skid-mounted design for easy transport and installation.
• Components: Includes adsorption towers, vacuum pumps, absorption columns, heat exchangers, and a central control panel.
• Storage: Store in a dry, well-ventilated area. If not installed immediately, protect electrical components from moisture.
