Load Rack Vapor Recovery System

Load Rack Vapor Recovery System

 

        Modern Bottom or Top Loading systems incorporate vapor recovery systems that control and collect vapors displaced form an empty compartment as it is filled and prevent them from escaping into the atmosphere and causing ozone damage. This is achieved by having a separate vapor recovery arm or hose adjacent to the loading rack which has a vapor coupler that is connected to the vapor adaptor on the tanker before loading starts. The compartment vapor vents on the tanker are connected to a manifold pipe and as the compartment is filled, the displaced vapor is directed down through the tanker vapor pipe and into the rack vapor arm. The vapors are then piped away for processing. The collected vapors can be flared off or processed with a Vapor Recovery Unit (VRU) and returned as liquid product back into the stock tanks. This puts valuable product back into the Oil Company’s inventory that would otherwise have been lost to the atmosphere. The recovered product is used to pay back the capital expenditure. Payback time is dependent on the turnover of the terminal.
