boil-off

boil-off

[′bȯil‚ȯf]
(textiles)
Removal of impurities from fabric by boiling the material in a solution.
(thermodynamics)
The vaporization of a liquid, such as liquid oxygen or liquid hydrogen, as its temperature reaches its boiling point under conditions of exposure, as in the tank of a rocket being readied for launch.

The technology is also applicable to LNG insulated tanks to lower boil-off gases.
Since the first production in 1996, Qatargas has delivered cargos to 31 countries and also operates the Jetty Boil-Off Gas facility, Al Khaleej Gas, two Helium Plants, the two Laffan Refineries (among the largest condensate refineries in the world), and the Ras Laffan Terminal.
There is also a problem concerning containment of the smallest molecule we know of at up to 700bar as hydrogen will 'evaporate' through most common materials, and even highly insulated tanks must allow for a 'boil-off 'of up to 5% of the contents daily to prevent over-pressurisation at lower pressures.
Since they would contain volatile and often cryogenic liquids, they were painted white to reflect the hot Florida sun at Cape Kennedy, to reduce the amount of boil-off, while waiting for lift-off.
He said this MoU to establish a company for the generation of electricity from solar power is a continuation of QP's environmental commitment demonstrated by various environmental projects, such as the reduction of gas flaring and greenhouse gas emissions, and the Jetty Boil-off Gas Recovery project.
