Minimizing the emissions of VOCS (Volatile Organic Compounds) from oil tankers during the fluctuating ambient conditions experienced during voyages is important from both environmental and commercial points of view.
The controlled release is often undertaken when the gas pressure approaches a pre-set point. However, it is not always clear at what pressure a manually controlled release should be stopped. Without this information, excess vapor can be released, causing air pollution and a loss of gas.
To meet this challenge, a VECS and Reporting System can be used to control the vapor pressure in oil cargo tanks to minimize and fully control VOC emissions. It is designed to comply with the latest international rules and regulations with an advanced reporting system.
The VECS is installed on the mast riser’s bypass line, and controls the vapor pressure in all the cargo tanks during voyage for direct emission control in order to reduce VOC loss from the tanks during voyage.
By controlling the pressure in the venting system, it is possible to fully control the VOC emissions.
The VECS can be programmed to enable adjustment of the opening setting on the valve according optimal level for the specific cargo.
