Oil And Gas Filtration Systems - ESG Filtration Ltd.

Canada is a large oil and gas producer and is home to many oil and gas facilities, mostly in Alberta, BC, Saskatchewan and Manitoba but with many facilities in Eastern Canada as well. Filtration and separation products are used in countless upstream, midstream and downstream oil and gas filtration applications by producers, service companies, transporters, refineries, etc.. ESG Filtration provides nominal and absolute rated filters and separation products for oil and gas applications in natural gas processing / gas plants, gas sample conditioning, natural gas transmission, oil pipelines, fracking, oil sands, SAGD, CSS, crude oil production, EOR, oil refineries, Liquefied Natural Gas (LNG) terminals and more.

Natural Gas Processing: Amine & Glycol Filtration

ESG Filtration provides products for numerous gas plant applications. Amine sweetening uses amines to remove hydrogen sulfide (H2S) and CO2 from raw natural gas. Natural gas plants in Alberta, British Columbia and Saskatchewan processing sour gas may have an amine contactor/absorber, amine regenerator (stripper/reboiler), lean amine filter and rich amine filter. Glycol Dehydration is used for removing water from natural gas and natural gas liquids (NGLs). Gas plants often have a glycol dehydration unit for removal of liquid vapor, with a glycol contactor/absorber, glycol regenerator, lean glycol filter, and rich glycol filter. Filters are used to remove particulates and contaminants from amines and glycols (i.e.: TEG, DEG, MEG, TREG). Optimized filtration can help prevent upset amine systems, contactor plugging, foaming, frothing, etc..

Natural Gas Processing: Coalescing of Inlet Gas, Fuel Gas, Sales Gas, etc.

Raw inlet gas entering a natural gas facility can contain liquid aerosol contaminants and may pass through an inlet separation vessel to remove slugs (large droplets) and then through an inlet gas coalescer where smaller droplets are removed. Coalescers are used as fuel gas filters for methane (CH4) entrained with contaminants, which may be coming from the inlet separator or glycol reboiler in gas plants, or raw gas or partially treated gas at compressor stations and other facilities. Sales gas filtration may involve high efficiency coalescers for the final removal of fine liquid and solid impurities from gas prior to entering sales gas pipelines.

Heavy Oil: Boiler Feedwater & Tailings Filtration for SAGD, CSS, Oil Sands Mining

Northern Alberta’s Athabasca, Wabasca, Peace River and Cold Lake oil sands operations involve unconventional oil resources containing viscous bituminous sands which require in-situ methods to extract oil. The Peace River, Bonnyville and Lloydminster oil sands areas primarily utilize Steam-Assisted Gravity Drainage (SAGD) and Cyclic Steam Stimulation (CSS, HPCSS) technologies to extract bitumen. In-situ operations often require boiler feedwater for steam production. In Northeastern Alberta around Fort McMurray and in the industrial heartland around Edmonton and Fort Saskatchewan, Athabasca oil sands ore is processed into synthetic crude oil through numerous separation processes at extraction plants and upgrader facilities. ESG Filtration offers filters and membranes that are suitable for many heavy oil applications in various facilities such as extraction plants, processing plants, upgraders, tailings ponds, and SAGD injection sites. ESG offers RO, NF, UF and MF membranes to remove salt & TDS from brackish water for steam, boiler feedwater filters, wastewater filters, boiler make-up water filters, boiler blowdown water filters, boiler condensate filters, evaporator blowdown filtration, SAGD produced water filters, bitumen froth filters, amine filters and more.
