FILTER-SEPARATOR Russian patent published in 2013 - IPC B01D45/08 

FIELD: process engineering.

SUBSTANCE: invention relates to oil and gas processing equipment, particularly, to coalescing, filtering and separating devices. Proposed filter comprises casing with gas-fluid mix inlets, pullet of gas, separated fluid and impurities, coalescing sections arranged therein and made from porous elements, and separation sections. Porous elements are composed of separated bulky porous vertically oriented plates arranged along gas-fluid mix feed, their surfaces being provided with gas-fluid mix flow supercharge grates on one side, and, on opposite side, with gas bleed grates. Several coalescing sections are arranged one after another in aforesaid casing wherein porous plates of next section are fitted opposite gas outlets from previous sections. Supercharge grates have tangential gas-fluid mix channels with open inlets while gas bleed grates have closed channels. Separation section is made of perforated separated plates with their surfaces furnished with porous vertical bundles and porous bundles of adjacent plates.

EFFECT: higher filtration efficiency.
