Upstream Oil & Gas Production (Onshore / Offshore Oilfields)

Core Pain Points

Crude oil contains sediment, rock cuttings, free water, emulsified water and scale particles. Drilling fluid and produced water feature high impurity content and high salinity, which easily cause blockages and abrasion of pumps and valves, as well as malfunctions of electric desalting units.

Supporting Filtration Solutions

Wellhead Coarse Filtration: Basket filters / Dual-parallel basket filters to intercept large-particle sediment and rock cuttings of 500~2000μm, protecting wellhead pumps and pipelines.

Crude Oil Oil-Water Separation: Gas-liquid / liquid-liquid coalescing separators for demulsification to separate free water and emulsified water from crude oil, and remove salt impurities.

Produced Water Reinjection Purification: Multimedia filtration + precise cartridge security filtration, controlling suspended solids (SS) ≤5mg/L to prevent formation blockage and corrosion of reinjection pipelines.

Natural Gas Wellhead Purification: Dry gas filter cartridges for dust removal plus coalescing liquid separation to eliminate wellhead condensate oil and water mist, safeguarding gathering and transportation compressors.

Recommended Equipment

Basket filters, vertical coalescing separators, skid-mounted automatic backwash multimedia filters, corrosion-resistant titanium filtration units for offshore service.

Midstream Oil & Gas Gathering, Transportation and Long-Distance Pipelines

Core Pain Points

Long-distance oil and gas pipelines carry iron rust, welding slag, condensate liquid and dust. These contaminants tend to block flow meters, pressure regulating valves and compressors, and bring risks of pipeline corrosion, liquid accumulation and deflagration.

Supporting Filtration Solutions

Main Pipeline Protection: Y-type and T-type straight-through filters installed upstream for coarse filtration to trap large particulate debris.

Fine Filtration for Gas Transmission Trunk Lines: High-precision pleated filter cartridges for 1~5 μm dust removal to protect gas turbines and booster compressor units.

Oil-Gas Two-Phase Separation: Horizontal coalescing filters that continuously remove liquid hydrocarbons and condensed water from natural gas to prevent liquid slugging damage to compressors.

Storage Tank Inlet & Outlet Filtration: Bag filters / self-cleaning filters to stop tank bottom sediments from flowing into downstream processes.
