Abstract
A degasser system having a central container and degasser tubes extending to the central container. A vacuum is maintained within the tubes and the container by means of a vacuum pump while liquid is extracted from the central container by a pump. A gas cut liquid is drawn into the tubes by vacuum and conditioned to assume a helical path through the tubes. The liquid is then dispersed into the tank where it is allowed to collect. The degasser intake is throttled as a function of the level of liquid within the container. The accumulated gas within the degasser is extracted from a central location in one of the tubes. The pump includes a housing for total emersion of the pump body, dual inlets, straight, radial impeller vanes, multiple volutes and an extended drive shaft to accommodate gas cut mud.
