• Below we show the main products used in the fore mentioned applications.

• It should be noted that other technology is utilised for other applications, for example, Air Scouring

will use the Tyr blower due to an overpressure requirement.

Vapour Recovery ApplicationsIntroduction

• Vapour recovery is a process used to recover environmentally hazardous and or valuable vapours.• The vapours are known as VOC = Volatile organic compounds.• There are two stages associated with this market.• Stage I: Capture of gaseous emissions and the transformation in the liquid phase, e.g. at ship

terminals, rail terminals, refinery’s as well as distribution depots and up to the service station storage tank.

• Stage II: Capture of gaseous emissions at the petrol filling stations and the transfer to the stage I terminal (no transformation into liquid state!).

Environmental Issues in the Oil & Gas Industry

• All Major Oil Companies have clear strategies with targets for VOC reductions.

• Most Global emissions policies stipulate a maximum HC emission level of 10g/m3.

• Some countries regulations are evenmore stringent, for example Denmarkand Germany both stipulate a maximum of 150mg/m3 (excluding methane).

• Crude Oil Terminals account for someof the largest single sources of VOC emissions in the world, with typical rates of 2kg vapour per ton of crude oil loaded.

Why Recover Vapour?

VOC Vapours are normally recovered for 3 main reasons:-

• To reduce emission of environmentallyhazardous substances.

• To reduce safety risks in the distributionof crude oil and fuels, mainly gasoline.

• To reduce significant losses of valuableenergy resources.

The Economics of Vapour Recovery are also very clear:-

• A typical Gasoline Terminal has an average recovery potential of approximately 1,500litres of Gasoline for every 1,000m3 of transferred product.

• The recovered Gasoline is not normally subject to “double” taxation.

• The pay-back time for a Gasoline Vapour Recovery system is often less than 12 months in service.

• In recent years, it has also become economically viable to recover vapour’s from crude oil loading and distribution.

Vapour Recovery Applications3.1. Stage 1

Applications for VOC Vapour Recovery include:-

• Storage Tank Venting• Rail Car Loading• Truck Loading • Marine Terminals• Offshore Ship Loading

A typical Vapour Recovery installation consists of 3 main elements:

• The Vapour Collection System (VCS)• The Vapour Recovery Unit (VRU)• The Absorbent System

We are interested in the VRU, which is typically a Carbon Vacuum-regenerated Adsorption (CVA) system.

Emission is drastically reduced by the installation of Vapour Recovery Units (VRU) at gasoline distribution terminals.

Vapour Recovery Applications3.1. Stage 1

The Recovery Process

• HC vapour is led from the emissionsource into one of two activated carbon beds in the VRU (Vapour Recovery Unit).

• HC molecules are adsorbed on thehighly porous carbon surface, and clean air is vented to atmosphere.Note: 7 gms of activated carbon have an active surface area the size of a large Football Stadium!

• Before saturation, vapour flow istransferred to the clean filter bed.

• The carbon is regenerated by meansof vacuum.

• Highly concentrated HC vapour is pumped to the absorber column, wherethe HC molecules are absorbed in a counter flow of absorbent (typically gasoline).

• The absorbent is continuously recycled to the storage tank.

• Before stage II, fuel vapour was vented to atmosphere.• Stage II implementation, the fuel vapours are now returned to the underground

tank to be collected by the fuel truck and returned to the fuel depot.
