FILTER-SEPARATOR FOR CLEANING AND COARSE DRYING OF METHANE GAS Russian patent published in 2006 - IPC E21B43/38 

FIELD: mining industry, in particular, ground-based equipment of wells for extracting methane from gas-yielding coal beds, possible use in composition of plant for finishing methane-coal well or preparation plant at mouth of methane-coal well for gas extracted from there.

SUBSTANCE: device includes two modules, each one of which contains cylindrical body with tangentially positioned branch pipes in its upper or lower sections. Positioned in the body are vessel for accumulating condensate, connected to output axial channel in its lower part, and filtering element with rigid perforated frame, cover and crater. In first module, filtering element is positioned on the outside of frame, cover is open in upper section, and mounted with a gap between body and filtering element. Second module is provided with tail open in lower section and a cowling mounted inside it, filtering element is positioned in it on the internal side of frame, enveloping tail with a space. Frame in first module, tail and frame in second module by their upper parts are connected to supporting bushings, mounted in upper part of body of appropriate module. Modules are interconnected mutually by means of tangentially positioned branch pipes in upper parts of their bodies. Branch pipe in lower part of body of first module is the inlet branch pipe, and branch pipe in lower part of second module - the outlet branch pipe.

EFFECT: possible simultaneous cleaning, filtering and coarse drying of gas immediately at well mouth.
