Gas separators mesh
Gas mesh separators are designed for final purification of natural and associated petroleum gas from liquid (condensate, hydrate inhibitor, water) in gas treatment facilities for transportation, as well as gas and oil refineries.
Structurally the separators are manufactured in two types:
Type 1 - cylindrical vertical with a body flange connector with a diameter of 600, 800 mm for a nominal pressure of 1.6 to 6.4 MPa (от 16 до 64kgf/сm2);
Type 2 - cylindrical vertical with a diameter of 1200, 1600, 2000 mm for conditional pressure from 0.6 to 4.0 MPa (от 6 до 40kgf/сm2).
