Development of Vapour Collection and Control Systems for Petroleum Storage Tanks

This paper reviews Trans Mountain’s progress in the development of vapour collection and control systems for petroleum storage tanks. These systems are specifically designed for removal of Hydrogen Sulphide (H₂S) vapours. The basic principles for vapour emission control and the design basis for the vapour control systems are reviewed. Experience with a number of adsorption processes is documented and current development work on an alternative vapour collection systems is presented.
