Patent ID: 8652233

Claim:
An apparatus for degasification of fluid, comprising: a separation tank; a first separation screen positioned within the separation tank, dividing the separation tank into an upper, gas-collecting section and a lower, fluid-collecting section, wherein the first separation screen comprises a plurality of orifices sufficiently small to catch and prevent passage of foam and bubbles that fall onto it, while allowing unfoamy fluid to pass through to the lower section; a fluid inlet port positioned in the upper gas-collecting section, for entry of fluid and entrained gas into the separation tank for degasification and fluid/gas separation; a foam-generating cup, configured to hold a small volume of fluid, positioned in the upper gas-collecting section above the first separation screen, and further positioned to receive the fluid and entrained gas from the fluid inlet port across an air gap above the fluid level in the cup to stimulate formation of bubbles upon contact between the fluids, and to allow a portion of the formed bubbles to then fall to the first separation screen below; a gas vent in the upper section allowing gas freed from the fluid to escape the separation tank; and a fluid outlet line in fluid communication with the lower section for conducting the degasified fluid from the lower section.
