The reduction of Volatile Organic Compound (VOC) from (Crude) Oil Storage tanks is a world-wide topic. Oil companies are obligated to reduce the discharge of VOC’s to the atmosphere.

An efficient way of realizing such targets is blanketing the tank head space with fuel gas. The main advantage of using fuel gas as blanket is that all VOC coming from the oil enters the fuel gas and therefore contributes to the energy production from the fuel gas when combusted, instead of polluting the environment.

The amount of VOC’s in the headspace of the tank will depend on pressure, temperature and medium stored in the tank.  The WIM COMPAS™ can be used for real time analysis of key combustion parameters such as Energy content (Wobbe Index or Heating Value) and Stoichiometric combustion air requirement.
