For conditioning and separation of spilled oilfield sludge, tank-bottom sludge, OBM cuttings and refinery oily sludge. The oil phase is recovered, the solids are brought below 2%.
C50N3 has completed multiple deliveries to oil & gas production bases across China. Supplier qualification and batch-by-batch retesting are part of ongoing supply.
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; particle size 2–100 mesh.
PL15 viscosity reducer (pretreatment), PAM cationic flocculant (aqueous-phase flocculation), PAC polyaluminium chloride (final clarification).
25 L / 200 L plastic drums with Chinese and English labels; full documentation for export orders.
Selected projects and supply records.
Multiple production bases across China, with multiple deliveries in recent years and ongoing bulk supply of C50N3.
Volume-reduction treatment of oily cuttings, with complete work plans, safety systems, testing records and personnel qualifications.
Chemical-plus-centrifuge (water wash) process, built on the client's own site, with annual treatment capacity at the 10,000-tonne scale.
Reduces and dilutes high-viscosity sludge for winter, low-temperature and high-wax conditions, improving transfer and agitation.
PAMFlocculation settling and aqueous-phase clarification; standard in the C50N3 process chain.
PACCoagulation of oily wastewater to remove oil and turbidity; final-stage clarification in the process chain.
Provide the sludge type, oil content and treatment volume, and we will give a selection assessment and target indices based on 19 years of field experience.
