Abstract
A gas trap assembly including a base connector housing including an inflow port and an outflow port, a reservoir fluidly connecting the inflow port to the outflow port, and a grooved porous media located within the reservoir. The grooved porous media including a plurality of grooves and composed of a material having a plurality of pores of a selected size. The grooved porous media fluidly divides the reservoir into two portions in such a way that a working fluid flowing from the inflow port to the outflow port must flow through the plurality of grooves and the plurality of pores of the grooved porous media. The plurality of grooves and the plurality of pores are configured to prevent gas from passing through the grooved porous media.
Claims13
A gas trap assembly, comprising:
- a base connector housing comprising an inflow port and an outflow port;
- a reservoir fluidly connecting the inflow port to the outflow port, wherein the reservoir is coupled to a venting and sampling port;
- and
- a grooved porous media located within the reservoir, the grooved porous media comprising a plurality of grooves and composed of a material having a plurality of pores of a selected size,
- wherein the plurality of pores are sized to prevent gas entering the inflow port from reaching the outflow port such that the gas is vented via the venting and sampling port and to pass a working fluid entering the inflow port such that the working fluid reaches the outflow port.
A component assembly for a gas trap assembly, comprising:
- a central tube;
- a grooved porous media circumferentially surrounding the central tube, the grooved porous media comprising a plurality of grooves and composed of a material comprising a plurality of pores of a selected size, wherein
- the plurality of pores are sized to prevent gas from passing through the grooved porous media,
- each of the plurality of grooves is formed by two opposing sidewalls that extend radially outward from the central tube, are separated at one end of each of the two opposing sidewalls to form a base that extends radially outward from the central tube at the one end of the two opposing sidewalls, and are joined at another end, opposite the one end, to form an apex that extends radially outward from the central tube at the other end of the two opposing sidewalls, and
- an apex angle measured between the two opposing sidewalls at the apex directly adjacent to the central tube and a second apex angle measured between the two opposing sidewalls at the apex radially outward from the central tube are a same angle or a different angle.
