Methane is over 25 times or 2400% more potent than carbon dioxide. It is a significant source of potent greenhouse gases.

There is an increasing awareness of the detrimental effects of greenhouse gases. Reducing methane emissions has become a top priority for industries.

One way to mitigate methane emissions is by using Vapor Recovery Units (VRUs), which capture and process methane emissions. In this article, we will explore where to find a VRU for sale. Discover why VRUs are a top choice for reducing methane emissions and carbon footprints.

What Is Vapor Recovery?

Vapor recovery is the process of capturing and recovering vapors released during oil and gas operations. Vapors include volatile organic compounds (VOCs), which are harmful to the environment and contribute to air pollution.

Capturing these vapors helps the oil and gas industry to reduce emissions and follow environmental regulations. Vapor recovery systems capture these vapors. They return them to the production process or storage tanks for later use.

Not only does it help reduce emissions, it allows for the recovery of valuable hydrocarbons that would otherwise be lost.

The Process of Vapor Recovery

This involves capturing the vapor and directing it to a vapor recovery unit (VRU) or other treatment system. The VRU removes the VOCs from the vapor stream and returns the hydrocarbons to the process or storage tanks.

Benefits

Vapor recovery provides several benefits to the oil and gas industry. The sale or reuse of recovered hydrocarbons provides additional economic benefits. Other benefits include:

  • Reduced emissions
  • Improved air quality
  • Increased production efficiency
What Is a Vapor Recovery Unit (VRU)?

It is a piece of equipment used in the oil and gas industry. They recover the vapors generated during the loading, unloading, and storage of hydrocarbon products.

These vapors are commonly referred to as Volatile Organic Compounds (VOCs). They include hydrocarbons such as methane, ethane, and butane.

VRU works by capturing VOCs and returning them to storage tanks or processing units. They are then available for reuse or sale.

This process reduces emissions, the risk of explosions and provides a potential revenue stream for the operators. VRUs come in a variety of sizes and configurations. They range from:

  • Small skid-mounted units
  • Large, complex systems for refineries
  • Petrochemical plants
Components

A typical VRU system consists of many components. The vapor recovery tower is where the vapor goes for treatment.

The compressor maintains pressure in the system and transports the recovered hydrocarbons. The control panel monitors and controls the VRU's operation.

Types of VRU Equipment

There are many types of VRU available. Each vapor recovery unit for sale on the market has its own unique features and capabilities. It is important to consider factors like cost, efficiency, and maintenance when purchasing VRU equipment.

Gas Lift VRUs

They use gas-lift technology to recover Volatile Organic Compounds (VOCs) from oil wells. The specific purpose of gas-lift VRUs is to reduce emissions of VOCs during oil production.

It injects natural gas or air into the oil well to lift the oil and gas to the surface. Workers can separate it at this point.

The VRU collects and processes the VOCs released during the separation process to minimize their impact on the environment. Gas-lift VRUs are an effective way to reduce VOC emissions from oil wells and help oil producers follow environmental regulations.

Wellhead Compression VRUs

This Vapor Recovery Unit recovers and minimizes emissions of VOCs from oil and gas production wells. They capture the gas released during the drilling and extraction process. They then process it through the VRU to minimize its impact on the environment.

This type of VRU works by compressing the gas released from the wellhead. This raises its pressure and temperature. It helps prevent the release of methane into the atmosphere during the production process.

Reciprocating Compressors

Their popularity in the oil and gas industry is due to their durability, efficiency, and reliability. They have the ability to compress vapor into high-pressure gas for storage or sale. Their compact size makes them beneficial for operations with limited space.

These compressors can handle a wide range of gasses, including high-pressure gasses. They are efficient and have low maintenance costs.

Flooded Screw Compressor VRUs

These compressors operate by compressing vapor using two interlocking screws. The compression process takes place in a flooded chamber, which provides cooling and lubrication.

This results in higher efficiency and reliability compared to other types of compressors. Flooded screw compressors are a popular choice in the industry due to their:

  • High performance
  • Energy efficiency
  • Low maintenance requirements
Rotary Vane Compressors

These compress gas through a series of vanes attached to a rotating rotor inside a cylindrical housing. They are ideal for handling high volumes of gas at low pressures. Their simple design makes them easy to operate and maintain.

They don’t handle high-pressure gasses well and are susceptible to damage from corrosive or abrasive gasses.

Liquid Ring Compressors

Liquid ring compressors are a reliable and efficient option for handling wet or saturated gas streams without damage or corrosion. They have a simple design with fewer moving parts.

This makes them easy to maintain and repair. They are less efficient and suitable for high-pressure applications than other types of compressors.

Tank Battery Vapor VRUs

This Vapor Recovery Unit recovers vapor from crude oil tanks at the well site. The specific purpose of tank battery vapor VRUs is to capture the vapor produced by oil stored in tanks. They work to reduce emissions and prevent the release of harmful pollutants into the environment.

They capture the vapors through a series of pipes and valves and then process them through a compression system. The compressed vapors are then sent to a storage vessel or pipeline for further processing.

Industrial Tail Gas Recovery (ITGR) VRUs

The specific purpose of ITGR VRUs is to recover the valuable hydrocarbons present in the tail gas stream. These would otherwise be lost to the atmosphere.

It accomplishes this by using a series of compressors and condensers to compress and cool the tail gas. This causes the hydrocarbons to condense into a liquid.

The liquid hydrocarbons are then separated from the remaining gas and returned to the process as a valuable product.

Buying New vs Used VRU Equipment

When it comes to purchasing Vapor Recovery Unit (VRU) equipment, buyers have the option to buy new or used equipment. There are pros and cons to both options that buyers should consider before making a decision.

Buying New VRU Equipment

Buying new is a good option for those who want the latest technology and equipment that is under warranty. The new equipment also has the benefit of being energy-efficient. This could save money on operating costs in the long run.

New equipment can be more expensive than used equipment. Buyers may have to wait for delivery.

Buying Used VRU Equipment

When searching for a VRU for sale, opting for a used unit can be a cost-effective choice for those with a limited budget. A used VRU may be available for immediate purchase, eliminating the wait for delivery.

Used equipment may not come with a warranty. They may have hidden issues that can lead to expensive repairs and maintenance. Buyers should inspect used equipment before making a purchase and factor in the cost of repairs and maintenance.
