Oil & Gas

Filter, liquid filtration, madd maxx, filter bags, Strainrite, clarity, oil, gas
Oil and gas production often takes place in extremely harsh environments. Typical filtration challenges include heavy fog, salt, spray, air pollution from other sources or very high dust concentrations. These conditions are also frequently impacted by the by-products of drilling and industrial contaminants like hydrocarbons.

For filtration of surface water used in make-up water, Strainrite offers multiple options including the EVP, Hi-Pro Micro or Madd-MAXX GF.

With produced water and onsite filtration, Microglass pleated elements at 2 micron efficiency helps prevent formation plugging. Strainrite’s Hi Pro Micro 9900 series or Glass-Pleat cartridge excels.

Strainrite offers valuable knowledge and a thorough understanding of downstream oil and gas applications, providing the most comprehensive filtration solutions for everything from refining to hydrocracking. Strainrite’s Madd-Maxx large diameter pleated filters excel at these critical tasks.
Amine Sweetening / Glycol Dehydration

​Amine Sweetening removes toxic and corrosive components, primarily hydrogen sulfide and carbon dioxide, from a hydrocarbon gas stream. Glycol Dehydration removes water to prevent corrosion or freezing of processing equipment. 

Part of the Amine/Glycol filtration process involves critical filtration steps such as:
  • Make-up Amine/Glycol Filtration: to protect downstream equipment from particulates that settle in storage tanks, to maximize operational efficiency and to minimize energy costs and foaming
  • Carbon Bed Pre-Filtration: to minimize large particulates that can foul the carbon beds and to improve operational efficiency and carbon resin life
  • Carbon Bed Post-Filtration: to prevent carbon particles from migrating down stream, to reduce unnecessary maintenance due to plugging and equipment damage and to maximize absorber performance
  • Sour Water Filtration: to protect water treatment equipment from contaminants caused by highly corrosive hydrogen sulfide and ammonia

​Proper filtration is critical to these processes. Contamination from particulate matter, foaming and other unwanted byproduct effects hampers operational efficiency when left unchecked by a poor filtration system.

For amine filtration requirements that are 10 microns and higher, Strainrite offers the polypropylene EVP with patented enhanced vertical pleat technology. For higher solids loading applications, the Madd-MAXX XL exceeds expectations. For 1 - 5 micron applications, Strainrite recommends the Madd-MAXX MF.

Glycol filtration is full flow, typically using 10 micron nominal filtration. Strainrite’s ​Visc-MAXX element easily replaces the majority of competitor brands. One P1 size element replaces 40 competitor 10” equivalent resin bonded cartridges.
Hydrocracking

Filtration is essential in the hydrotreating process to remove contaminant sources resulting from catalytic reactions and feedstock impurities.

Refineries use the hydrotreating process to remove sulfur from petrochemical feed stock through a catalytic conversion. These feed stocks are combined with hydrogen and fed into the fixed-bed catalyst hydrotreater at high temperatures and pressures. Contaminant sources include sulfide from the catalytic reaction and feedstock impurities which would significantly reduce productivity.

Strainrite’s products will effectively filter out contaminants from feedstocks, lubrication oil, make-up hydrogen, desulfurized hydrocarbon and sour water sources.
Storage, Transfer, Final Product Filtration

For amine, diesel, gasoline, heating oils, heavy fuel oils, jet fuel, kerosene, naphtha and many other products, final filtration occurs both during and after processing, refining, storage and transfer. Through the network of pipelines and storage systems, water, dirt and other contaminants belie the need for the highest quality microfiltration systems to meet customer specifications.

Strainrite’s products will ensure the highest quality microfiltration to ensure fluids are free of contaminants during the storage and transfer process.

Frac Tanks are key to portable water storage solutions. Sometimes called fixed-axle storage tanks, frac tanks provide safe and secure water storage. Frac tank filtration and salt water disposal wells require versatile solutions. Strainrite delivers solutions. If no oil is present Strainrite’s EVP bags (10 micron is standard) will do. When oil is present Strainrite offers the BRB or Visc-MAXX (10 or 25 micron). No need to replace cartridge housing already on site. Strainrite offers the CRB-Pleat resin-bonded cartridge.

For rail car and tank loading /offloading of oil based streams, Strainrite’s BRB bags are recommended, provided polyester fibers are chemically compatible.
