C50N3 is a water-based blend of non-ionic surfactants that acts on the oil–water–solids interface, releasing oil from solid and equipment surfaces so it can be separated and recovered. Its main uses cover conditioning and separation of spilled oilfield sludge, tank-bottom sludge, OBM cuttings and refinery oily sludge, and it is applicable to a wide range of petroleum-based cleaning tasks including vehicle and component degreasing, metalworking de-oiling, and oily pipeline and tank cleaning.
C50N3 is a water-based liquid built around non-ionic surfactants. Wetting, demulsification and interfacial displacement strip adsorbed and emulsified oil from solid surfaces into a separable oil phase; the formulation does not change the composition of the material. Dosing ratio, cleaning temperature and contact time are set against the actual feed and working conditions.
C50N3 acts on the oil–water–solids interface. The chemical does not change the composition of the sludge — only where the oil is.
The agent adsorbs onto the solid surface, changes the particles' wettability and breaks the interfacial film around the oil phase, stripping adsorbed oil and emulsified oil off the sand and clay surfaces.
With hot water (recommended above 60 °C) and mechanical agitation, the desorbed oil floats up and coalesces while the water phase carries the fines, completing a primary phase split dominated by solids–liquid separation.
The separated slurry goes to the centrifuge; the solids (oil content <2%) are discharged, the oil phase is recovered, and the oily water enters the PAM + PAC coagulation-flocculation stage for clarification and reuse.
The dosing ratio is determined by the material's properties and must be based on bench-test results. Below is the typical procedure and reference ranges.
Spilled oilfield sludge, tank-bottom sludge, OBM cuttings, refinery oily sludge and gathering-station tank-cleaning sludge; vehicle and component degreasing, cutting fluid residue, metal surface de-oiling, oily pipelines and tanks. Particle size 2–100 mesh applies to sludge-type materials.
PL15 viscosity reducer (pretreatment), PAM cationic flocculant (aqueous-phase flocculation), PAC polyaluminium chloride (final clarification).

Beyond the conditioning and separation of oily waste, C50N3 is applicable to a wide range of petroleum-based oil contamination cleaning tasks, including vehicle and component degreasing, metalworking de-oiling, and oily pipeline and tank cleaning. Dosing concentration and cleaning temperature are confirmed by a bench test with the actual material, since substrates and oil types vary.
Engine, bearing, gear and workshop parts degreasing; ship cargo tanks, engine rooms, decks, fuel tanks and ballast tank cleaning.
Cutting fluid residue removal, metal surface de-oiling and machinery maintenance cleaning.
Cleaning of oily pipelines, oily water lines, storage tanks and heat exchangers.
