Vapor Recovery Towers (VRT’s) are tall pressure vessels, built in accordance to ASME Section VIII, Division I, that are installed between production separators and liquid storage tanks. The best VRT’s are engineered for proper retention time to allow gas to separate from the liquid, without potential for trapping liquids in gas piping leading to a VRU (Vapor Recovery Unit).
Our standard sizes are 24” to 48” diameter with heights to 40 feet each. Most of our VRT’s are designed to work with pressures between 50 and 175 psig, but they usually only have to gravity-feed the liquid storage tanks at a very low pressure (about 1 psig). In most cases, the flash gas that comes from the liquids in the VRT goes to a vapor recovery unit so it can be compressed.
Vapor Recovery Towers are used to collect and recover volatile organic compounds (VOCs) from gases produced in many industrial processes. These towers help reduce air pollution by recovering harmful VOCs before they can be released into the atmosphere. They do this by trapping the volatile components of a gas mixture and converting them into liquid form, which can then be collected and stored.
One of the most importance of Vapor Recovery Towers is environmental conservation. Volatile Organic Compounds (VOCs), if released into the atmosphere, contribute to the formation of ground-level ozone, a primary component in smog. This not only affects air quality but can also harm the environment and human health.
Some benefits of using VRTs include:
- Reduce flash emissions
- Capture more product for sales
- Improve site revenue
- Protect VRUs (Vapor Recovery Units) from vapor pressure surge
- Prevent vapor release from tank thief hatches
- Reduce and eliminate VOC emissions
- Manage heavy and lighter grade crudes
- Reduce back pressure on storage tanks
- Minimize and eliminate oxygen in gas pipelines
- Reduce regulatory risk
