PLANT FOR METHANE-AND-COAL HOLE DEVELOPMENT AND PRODUCED GAS CONDITIONING Russian patent published in 2007 - IPC E21B43/00 

FIELD: mining, particularly land-based equipment for holes adapted to produce methane from gas-bearing coal seams.

SUBSTANCE: plant comprises gas cleaning line and liquid cleaning line to be connected with hole annuity outlet and with tubing space outlet correspondingly. Gas cleaning line is provided with filter separators each comprising at least two modules, which may operate simultaneously or one after another. Filter separator are installed in liquid cleaning line. Condensate filter separator inlet is connected to condensate discharge line, which discharges condensate from gas cleaning line filter separators. Condensate filter separator outlet is linked to cleaned liquid discharge line connected to liquid outlet of liquid cleaning line filter separator outlet. Gas outlet of condensate filter separator is communicated with gas outlet of liquid cleaning line filter separator. Cleaned gas discharge line includes section provided with control and measure means. Plant also has necessary locking units and bypasses. Modules of each filter separator filter have tangentially arranged pipes located in upper and lower parts thereof and condensate accumulation vessels communicated with condensate discharge line of gas cleaning line filter separators through outlet axial channels. Module interiors are communicated with each other through tangential pipes in upper module part. Tangential pipes in lower module parts are used as inlet and outlet pipes correspondingly.

EFFECT: possibility to develop methane-and-coal holes and produced gas conditioning directly at well head.
