SuperSat – prevent evaporation and reduce loss!

By maintaining a continuous high pressure the SuperSat reduces buildup of volatile organic compounds (VOC) reducing emissions and subsequent loss of cargo.

The boil-off of cargo that evaporates through p/v-valves is increasingly problematic for the industry. Emissions are bad for the environment and a cause of loss. By preventing this loss, the SuperSat is not only an environmental sound choice for your company, it is also a solution with an attractive return on investment.

Key benefits of the new SuperSat:

The SuperSat system continuously and without interruptions maintain cargo tank pressure at a high level. Our high velocity valves feature a negative pressure drop as a last resort safety valve, and thus the higher pressure is achieved without compromising safety. This is essential for VOC containment during loading and throughout the entirety of the journey. The benefits of this is to:

  • Reduce emissions
  • Maintain continuous pressure
  • Save money
  • Protect the environment
  • Reduce fire hazards
  • Suppress VOC buildup

How SuperSat prevents loss of cargo

Control of the pressure within a crude oil cargo tank vapor system will determine the extent of further vapor evolution. If the pressure within the system is controlled at or above the Saturated Vapor Pressure of the cargo, then equilibrium pressure between the liquid and vapor phases is obtained, and no further VOC will evaporate.

The physics are the same for Flashing and Breathing losses, since VOC emissions occur when a liquid with entrained gases goes from higher pressure to a lower pressure. Keeping the pressure high and stable will eliminate escalated VOC loss on tankers and will, when implemented on FPSOs, reduce the total VOC loss from field to terminal to a fraction.

At pressure below SvP the formation of VOC escalates and are flashed to atmosphere.

At high pressure, the VOC are held down and won’t evaporate.

Compounds that are liquids at the initial pressure/temperature transform from a liquid into a gas/ vapor and are “flashed” from the liquid.

Stop wasting money –
reduce losses today

An average loss of 0.13% of the cargo to evaporation sounds like it is next to nothing, but in an Aframax tanker carrying 114.000 tonnes oil 0.13% evaporation amounts to a loss of more than 40,000 USD per voyage.

The latest predictions indicate that as much as nine million tonnes of VOC could be emitted annually due to crude oil transport. This corresponds to about 70 million barrels of light end hydrocarbons representing a value of 3.0 to 3.5 billion USD a year.
The SuperSat reduces evaporation loss by keeping VOC formation low. Start saving today. Please contact us on how we can help you.

Built for the future to meet increasingly strict environmental requirements

As care for the environment grows as a focus, governments are introducing stricter regulations for vessels operating within their jurisdiction. Recently introduced Norwegian legislation has banned the emission of potentially dangerous gases from tankers and it is likely that legislation that mimics these initiatives will follow around the globe.

The SuperSat VOCON system is built to ensure both environmental safety, profitability and compliance for enterprises in the future. SuperSat is the smart valve of the future built to fight pollution and at the same time offer our clients a solution with an attractive return on investment.
