An overview of Vapor Recovery Systems
Vapor Recovery Systems are designed for collecting vapors of refined petroleum gasses and other fuels, otherwise, they will be realized into the surrounding atmosphere. They are primarily used in gas filling stations, to minimize poisonous and potentially combustible fumes and pollution.
It provides a challenging advanced technology in treating the liquid hydrocarbon streams using the innovative organic solvent through a nanofiltration process.
Some of the unexceptional vapors to be treated in vapor recovery systems are Petrol, Methanol, Benzene, Toluene, xylene, diesel, naphtha, crude oil, etc. These harmful gasses are handled with the highest safety and quality standards into consideration. The whole apparatus including the membrane systems and modules should guarantee operational safety, maximum efficiency, and optimum cost-effectiveness.
Working principle of vapor recovery systems: This system consists of two carbon vessels for uninterrupted operation. Here the process starts with Vapors passing through the Vapor Recovery Units, as they progress through a vessel of activated carbon that engrosses all the hydrocarbons present in it and permits the clean air to exit the system. As the carbon vessel reaches its highest capacity, a vacuum pump can then remove the hydrocarbon vapor, pass this to an absorber tower, and restore the vapor back to a liquid state, so it can be put back into the tanks.
This system is comparatively new to this technology and has several advantages in the gasoline and petrochemical industries. The system is customized and manufactured as per the requirements and specifications of the customer’s utilization. Let’s discuss the various advantages of this system in this article
The benefits of vapor recovery systems include
- It is extensively used in the chemical process industry to withdraw and recover vapors from large storage containers.
- Compact design, ease of maintenance, and affordable cost make the product unique.
- The recovered vapors are again reused and re-ejected into oil wells, sent to users, or used as fuel,
- To attain high efficiency and restore of fuels.
- For recovery of waste gasses in plants that can be ceased and used for later purposes.
- Results in increased revenue or cost reduction for the facility.
- It maintains the social and environmental responsibility of the individuals.
- These systems have found diverse applications in marine vessels and also used in the ship, truck, and railcar filling of fuels and to shield the recovery equipment from internal system sources and external on-site ignition sources.
- Helps in providing minimum air pollution
- Durable and secure for all products.
- The blower is not required and has a high self-absorption principle.
- Vapor recovery systems are designed to seize about 95% of Btu-rich vapors in Natural gas processing plants
- This system imparts higher collection efficiency and maintains a good Air/Liquid ratio.
Hence Vapor Recovery Systems (VRS) are invented to separate out the unwanted vapors present along with the crude oil or distillate tanks allowing operators to follow precautions with prevailing emission control management. They are manufactured with vast knowledge in operational design, and detail engineering and contributed to adsorption systems and skid launching units.
