Project Tank Vapors - Case Study
Project Overview:
In 2015 Questor was selected to provide emissions control for a truck loading and tank vapors at a Shell oil battery in Alberta, Canada. The waste gas stream consists primarily of rich gasses, ethane (~19 mol%), propane (~35 mol%), butane (~24 mol%) and remaining hydrocarbons, ~35 mscf/d of fuel gas is required to draw the low pressure waste gas stream into the thermal oxidizer and generate a combustion vortex. Questor’s proprietary combustion technology utilizes the pressure of the incoming fuel gas stream to create an internal vortex for homogenous mixing and highly efficient combustion. The Company has a resume of handling similar waste gas streams at loading facilities and is well equipped to handle the unique challenges associated with these facilities. The pressure from the gas separator was used to induce the low-pressure tank vapors and sufficient combustion air into the thermal oxidizer to control emissions in an operation that experienced significant surges and dips in flow rates. This new process design has eliminated the need for a small VRU previously used on site. This design also includes a forty foot (40’) stack (a standard 30’ with a 10’ stack extension) which will ensure adequate residence time to complete the combustion of the waste gas stream.
