Vapour Recovery Unit Maintenance
Vapour Recovery Units are complex mechanical and electrical systems, which operate in hazardous atmospheres. Failure to service units correctly can lead to financial inefficiencies, operational issues, safety complications or environmental emission problems. FlotechPS supports all types of Vapour Recovery Units and employs specialists in control instrumentation and electrical engineering. Our engineers have been trained and are equipped with everything needed to maintain and test this type of equipment and keep it effective.
Vapour Recovery Units can be >99.9% efficient at recovering released VOC’s produced during gasoline storage, loading and unloading; an efficient unit will recover approximately 0.15% of the gasoline loaded at a terminal. Benefits include:
- Reduction in VOC’s – Environment improvement
- Improved safety – Reduced risk of flammable atmospheres
- Financial – product gains
The release of Volatile Organic Compounds (VOC’s) has an impact on human health due to the carcinogenic components and pollution of the troposphere; creation of ozone. In 1990 European VOC’s released to atmosphere amounted to 17 million tons per year, the implementation of legislation as defined in the Rio Declaration On Environment & Development resulting in European countries signing the Geneva Protocol, committing to a reduction of manmade VOC’s. A contributing factor was the evaporation of gasoline vapours during storage, loading and unloading. European Directive EC95/63 later transposed into national law by each member state required member states to implement appropriate measures to control such emissions.
A range of Vapour Recovery Services, from preventative maintenance, compliance and HM customs & testing, aimed at optimising unit performance and reliability.
Preventative maintenance tailored to individual requirements to include:
