Introductionto the Stage 2 Vapour Infuser

A NEW ERA OF VAPOUR MANAGEMENT MAKING YOUR SITE MORE PROFITABLE

VCS Limited

Stage 2 VapourThe Facts:

Stage 2 vapour is an indirect delivery to your siteIt is vapour gained from the car fuel tank not

deliveredIf converted to liquid this will provide you with

additional stockProcessing this vapour will reduce Wet Stock

LossesProvides a payback from Stage 2, if processed.

Stage 2 – A Delivery from the Pumps

Stage 2 vapour is collected, from all nozzles supplying petroleum products, at the neck of the nozzle, and

returned to one tank via a manifold

Tank Deliveries – Stage 1B

Normally, most Stage 2 vapour is taken by the tanker when connecting to the Stage1B system during the delivery process

Basic Principle of Stage 2

The stage 2 vapour is returned to one tank, whilst the product could be supplied from a number of tanks.

This creates increased pressures and rapid expansion causing temperature differentials and turbulence.

Stage 2 – The Effect on the Tank

Pressure increase within the tank farm

Extreme vapour generation due to thermal differences.

Venting of excess pressure to the atmosphere due to air/vapour

expansion

Increased stock losses

Stage 2 – Temporary Solution

A Hole !!!!Existing solutions merely transfer the same problem to

another part of the forecourt

Stage 2 – Solution

The Infuser

Stage 2 – The benefits of the Infuser

• Calming the entry of the stage 2 vapour/air mixture • Balancing the temperature between the mixture and tank

• Reduce operational pressures in the tanks

• Increased site safety

• Environmentally beneficial

• Provide a payback on the expense of Stage 2

Stage 2 – Infuser Installation

The infuser is installed within the storage tank below the Stage 2 entry.

Thereafter no maintenance is required

Stage 2 – Infuser Return

Based on a standard sales of 2,500,000 litres of petrol per annum

Vapour/Air collected – 2,500,000 litres (1:1 ratio)

Air/Vapour concentration ratio 50/50

Saturated Petrol vapour collected – 1,250,000 litres

Divided by 846 (known conversion factor vapour to liquid)

= 1,477 litres of liquid
