Refrigerated Vapour Recovery System (RVRS)
From Vapour Recovery
The Refrigerated Vapour Recovery System (RVRS) is a flexible solution to reduce the VOC emissions and is available in mobile and fixed version. The system recovers clean product from the vapours without reportable emissions. PURGIT RVRS uses a proprietary system that condenses and recovers tank vapours. Depending on the application PURGIT's condensers are capable to recover over 99% of the VOC. The RVRS is able to cool down the vapours to approximately -120°C.
PURGIT RVRS uses a proprietary system that condenses and recovers tank vapours. This system draws the vapours out of the tank with a blower and then pushes them through a series of condensers. The VOC vapours are condensed back to their liquid phase and transferred to a holding tank or inserted right back into the cargo fill line. Depending on the application PURGIT's condensers are capable of recovering over 99% of the VOC. With few moving parts and stainless steel construction, these units are designed to operate for many years with minimal service.With the RVRS system VOC compounds are easily recovered. There is no combustion. Using non polluting nitrogen as the refrigerant, this system is capable of the very low temperatures necessary to condense a wide range of products*. The RVRS's vapour recovery unit have been thoroughly tested in the field with a wide variety of products and have established a long track record of reliability and success.
Tank loading / discharging
For tank loading/discharging the PURGIT system can be geared to draw displaced vapours out of the tank with a blower and then push them through condensers.
The VOC ‘s are condensed back to their liquid phase and transferred to a holding tank or inserted right back into the cargo fill line. Final treatment of the vapours is achieved with re-usable active carbon.
There is no combustion during the process which allows this system to operate in a larger number of areas than any other system.
Close Loop Tank Degassing
The PURGIT RVRS system is designed to degas atmospheric or inert tanks and barges (low or zero O2) and keep it inert throughout the operation. Drawing VOC vapours out of the tank, the PURGIT system condenses and removes the hydrocarbons from the vapour stream, returning only the non-condensables to the tank.
Close Loop Tank degassing with the RVRS is completely safe and the tank can be inerted during the process. Condensing and removal of the VOC in the tank or barge will continue until the required LEL level is reached.
