Oil-sludge reduction and recovery solution

Compare separation, dewatering, drying and thermal scope against water, oil, solids and contaminant data.

Feedstock testing and mass balance are prerequisites for route selection.

Oil, gas and industrial oily waste

Start oil-sludge treatment with water, oil, solids and contaminant evidence

Oil sludge may originate from drilling, refining, tank cleaning, oil transport or contaminated sites. Water, oil, solids, salts, metals and viscosity vary significantly, so mechanical separation, thermal washing, dewatering and drying should be compared before defining the thermal scope.

Common project settings

Oil and gas drilling

Oil-based cuttings and field sludge require review against the drilling system and local hazardous-waste rules.

Refineries and petrochemicals

Tank-bottom, separator and maintenance sludges need source-specific sampling because compositions differ.

Storage and transport facilities

Tank cleaning, depots, terminals and ship repair often require oil-water-solid separation first.

Contaminated-site remediation

Oily soil and legacy waste require soil testing, a remediation target and a defined final route.

Feedstocks for combined-process review

  • Tank-bottom sludge, refinery sludge and separator sludge
  • Oil-based cuttings, field sludge and confirmed oily soil
  • Materials with representative samples and water-oil-solid analysis
  • Projects with defined testing, transport, treatment and residue-management duties

Boundaries to confirm first

  • Whether high-water material needs separation or thermal washing first
  • Salts, metals, sulfur, chlorine and other contaminants
  • Viscosity, particles and foreign objects affecting transport and heat transfer
  • Treated solids and water cannot be declared reusable before testing

Typical oil-sludge reduction and recovery chain

01

Sample by source

Record origin, storage time, condition and batch variation separately.

02

Laboratory analysis

Measure water, oil, solids, ash, salts, metals and priority contaminants.

03

Front-end separation

Compare settling, screening, centrifuging, thermal washing, dewatering and homogenization.

04

Dry and meter feed

Control moisture, viscosity and particle size to reduce heat load and feeding risk.

05

Treat thermally and condense

Recover condensable oil gas while managing process gas, odor and system safety.

06

Test all three phases

Test recovered oil, water and treated solids against the required downstream route.

Main material streams and downstream work

Recovered oil

Quality depends on feedstock and pretreatment; test before fuel use, refinery return or further upgrading.

Water phase

Separated or condensed water may contain oil or salts and must enter an appropriate treatment system.

Treated solids

Test residual oil, metals and other contaminants before reuse, remediation acceptance or disposal.

Process gas

Collect and treat it in a closed system and evaluate controlled heating reuse.
