VRU Major Components and Features

A VRU is an essential piece of process and production equipment used in the oil and gas industry to control volatile organic compounds (VOC) emissions produced while transferring and storing crude oil, refined petroleum products and natural gas. A typical VRU has several components that work together to achieve this task. These components include a compressor, a refrigeration system, heat exchangers and control systems.

Common asked questions

A Vapor Recovery Unit (VRU) is a process and production equipment used to capture and recover volatile organic compounds (VOCs) from industrial processes or storage tanks. These VOCs may include gases like methane, butane, propane, and other hydrocarbons that are typically emitted during the transfer of petroleum products or the processing of chemicals.

A VRU works by pulling the vapors from the storage tanks or equipment into a closed system through a series of pipes and valves. The vapors are then compressed and cooled to condense the VOCs into a liquid form, which can be collected and reused or disposed of safely. The recovered hydrocarbons can be used as fuel or returned to the production process, while reducing emissions and minimizing air pollution.

VRUs are commonly used in the oil and gas industry to control emissions from oilfield operations, refineries and transportation terminals. They can also be used in other sectors, such as chemical manufacturing, petrochemical processing, and pharmaceutical production, among others.

Vapor recovery units (VRUs) reduce air pollution emissions by capturing vapors and gases that would otherwise be released into the atmosphere. These vapors and gases can come from various sources, such as storage tanks, loading facilities and pipelines. When these vapors and gases are discharged into the atmosphere, they contribute to air pollution and greenhouse gas (GHG) emissions. Capture and recovery of these vapors through VRUs prevent them from being released into the atmosphere, and instead, they are treated and recovered for reuse.
