Quick answer: Plate-and-frame and chamber filter presses for oil and gas plants dewater drilling mud, frac flowback solids and refinery sludge so solids can be hauled dry and water reused or discharged. Oil-resistant cloth, polypropylene or coated plates and, where required, explosion-proof electrics and enclosed cake handling are specified for this duty.
Oil & Gas Plant Plate Frame Filter Press & Filter Plate Supplier
- Efficient Dehydration: Through the combination of precision filter plates and filter cloths, the moisture content of the filter cake is as low as 45–60%, significantly reducing subsequent processing costs.
- Corrosion & Oil Resistance: Key parts are made of polypropylene and fluororubber materials, specially processed to resist corrosion from strong acids, alkalis and various oil media.
- Drilling Mud Recovery: Efficiently separate solid particles, recycle drilling fluid and reduce mud treatment costs.
- Oil Production Wastewater Treatment: Remove suspended matter and sludge to achieve standard discharge and resource utilization.
- Refinery Washing Water Purification: Deeply remove oil and particles in washing wastewater to protect subsequent process equipment.
- Oil Sludge Solidification & Dehydration: Dewater high-oil sludge into a solid cake, reducing transportation and disposal costs.

Buyer FAQ
Can the press handle oil-wet or hot sludge?
Yes. PP plates and oil-resistant PP or PET cloth handle oily slurries; for temperatures above about 90 °C or aggressive solvents, reinforced or metal-cored plates and PTFE or PA cloth are specified.
Is an explosion-proof version available?
Explosion-proof motors, controls and hydraulics can be specified for hazardous-area installations; state the zone classification with your enquiry.
What micron rating should the filter cloth have?
Cloth is chosen by the particle size of the solids: typically 5–25 µm equivalent for fine refinery sludge and coarser for drilling cuttings. A slurry sample lets us pick the cloth that gives clear filtrate without blinding.
