Abstract
Abstract A degasifier for separating gases or vapors from gas/liquid or vapor/liquid flows in pipelines having a horizontal pipe section in which the flow is diverted by providing a back flow panel of a particular design in a particular position in a suction pipe which panel causes separation of bubbles which are removed by the suction pipe, captured in a container situated above the branch pipe and then exhausted therefrom. The degasifier consists of simple parts, has a small volume and can be applied to reduce gas content of a liquid flowing in a pipe for reduced flow resistance.

Claim 1
Independent Claim
210 words
A degasifier for separating gases from gas/liquid flows in pipelines by means of a pipe section mounted into said pipelines, said pipe section comprising: a branch pipe attached to said pipe section and disposed, with regard to the flow direction at an angle of not more than 90°; container with substantially larger cross-sectional area than the pipes disposed above the branch pipe and being attached to the branch pipe by means of a conical intermediate section; a gas discharge pipe disposed at the container's upper end; a suction pipe arranged with its inlet disposed in the branch pipe above the jointure thereof with the pipe section and extending into the interior of the container above any liquid level therein; a back flow panel arranged in the branch pipe and being attached perpendicularly to the inner surface of the branch pipe, the outer ends of said back flow panel in the branch pipe being bent downward along its inner surface toward said pipe section; the upper end of the back flow panel being situated in approximately the same plane as the inlet of the suction pipe between said suction pipe and the inner surface of the branch pipe so as to block direct communication between the two at their closest point.

A degasifier for separating gases from gas/liquid flows in pipelines by means of a pipe section mounted into said pipelines, said pipe section comprising: a branch pipe attached to said pipe section and disposed, with regard to the flow direction at an angle of not more than 90°; container with substantially larger cross-sectional area than the pipes disposed above the branch pipe and being attached to the branch pipe by means of a conical intermediate section; a gas discharge pipe disposed at the container's upper end; a suction pipe arranged with its inlet disposed in the branch pipe above the jointure thereof with the pipe section and extending into the interior of the container above any liquid level therein; a back flow panel arranged in the branch pipe and being attached perpendicularly to the inner surface of the branch pipe, the outer ends of said back flow panel in the branch pipe being bent downward along its inner surface toward said pipe section; the upper end of the back flow panel being situated in approximately the same plane as the inlet of the suction pipe between said suction pipe and the inner surface of the branch pipe so as to block direct communication between the two at their closest point.
Claim 3
Dependent Claim
73 words
A degasifier according to claim 1, wherein a deflection plate is arranged within the container below the liquid level and around the suction pipe; a float is provided floating on the liquid and having operatively associated therewith a valve member adapted to engage and seal the gas discharge pipe depending on the height of the liquid level and a liquid droplet separator is arranged between the liquid level and the gas discharge pipe.
