Abstract
An apparatus is disclosed including an encasement defining a gas inlet to receive a gas stream and a gas outlet to release the gas stream. The apparatus further includes a vertical baffle attached to an encasement top within the encasement, the vertical baffle in contact with at least one horizontal baffle, the baffles separating the encasement into at least one chamber. The gas stream passes through the at least one chamber through perforations on the at least one horizontal baffle, and particulates from the gas stream are deposited on the encasement or the baffles.
Claims10
A method of removing gas from drilling fluid, the method comprising:
- providing a used drilling fluid having gas entrained therein;
- removing the gas from the used drilling fluid, wherein the removed gas is in a form of a gas stream;
- providing an encasement comprising a gas inlet, an atmospheric inlet, and a vertical baffle in contact with at least one horizontal baffle that extends on both sides of the vertical baffle, wherein the vertical baffle and the at least one horizontal baffle separate the encasement into a plurality of chambers and the vertical baffle has a continuous surface with no perforations preventing fluid communication therethrough;
- passing the gas stream into the encasement through the gas inlet, deflecting the gas stream downward from the gas inlet, and passing the gas stream through the plurality of chambers of the encasement and through perforations on the at least one horizontal baffle;
- receiving incoming air from the atmospheric inlet;
- and
- depositing particulates from the gas stream on at least one of the encasement, the vertical baffle, and the at least one horizontal baffle.

A method of removing gas from drilling fluid, the method comprising:
- providing a used drilling fluid having gas entrained therein;
- removing the gas from the used drilling fluid, wherein the removed gas is in a form of a gas stream;
- providing an encasement comprising a gas inlet, an atmospheric inlet, and a vertical baffle in contact with a first horizontal baffle and a second horizontal baffle that extend on both sides of the vertical baffle, wherein the vertical baffle, the first horizontal baffle, and the second horizontal baffle separate the encasement into a plurality of chambers, the first horizontal baffle has first perforations defining a first baffle voided area, the second horizontal baffle has second perforations defining a second baffle voided area, and the second baffle voided area is greater than the first baffle voided area;
- passing the gas stream into the encasement through the gas inlet, deflecting the gas stream downward from the gas inlet, and passing the gas stream through the plurality of chambers of the encasement and through perforations on the at least one horizontal baffle;
- receiving incoming air from the atmospheric inlet;
- and
- depositing particulates from the gas stream on at least one of the encasement, the vertical baffle, the first horizontal baffle, and the second horizontal baffle.
