1. Desludging & Oil Recovery Solutions

PSI chemistry is a proprietary blend that enhances several oil and gas applications and processes. It is an anionic formulation with an affinity to attract to negative surfaces. I’m pleased to share that PSI is approved by SAUDI ARAMCO and ADNOC, and the approval process is currently underway with PETROLEUM DEVELOPMENT OMAN (PDO) and THE BAHRAIN PETROLEUM COMPANY (BAPCO).

Applications:

  • Crude Oil Tanks
  • Slop Oil / Black Oil / Heavy Fuel Oil Tanks
  • Desalters & Dehydrators
  • Separators & Other Production Vessels
  • Flowlines & Pipelines – including fully clogged and non-piggable lines

PSI will disperse and release Wax, Asphaltene, and Sand deposits in the sludge, liquefying it into a pumpable form, which significantly eases the cleaning process and minimizes the time required to clean tanks and vessels. Solids and liquids will be separated. Being water-soluble, PSI will not travel in the oil phase but will precipitate out in the water phase, without influencing the oil properties. PSI's unique ability to break the bonds of interfacial surface tension between solids and liquids enables production equipment to operate within its designed range, resulting in a cleaner and more efficient process while maintaining a safe and environmentally responsible working environment.

Highlights:

  • Sludge depositions are gradually liquefied molecule by molecule, so no chunks of solid sludge flow downstream.
  • Hydrocarbon gets broken down into hydrocarbons.
  • Salts and other solids drop into the water phase.
  • PSI solution drops into the water phase.
  • No influence on the chemistry of liquid – oil – Compatible with Hydrocarbons.
  • Significantly minimizes time for desludging.
  • 95% of oil sludge is recovered back into the oil stream.
  • Integrates with the existing scope of work of the user with minimal changes in the current cleaning program.
PSI Chemistry

We are proud to highlight PSI proven track record in successfully executing large-scale desludging operations for major clients like Saudi Aramco, with projects involving high-capacity crude and slop oil tanks. These projects were completed safely, efficiently, and within remarkably short timelines, demonstrating the speed and reliability of our PSI chemistry in real field conditions.

    1. • Successfully desludged a 90,000-barrel dry crude tank (Tank ID 369 T-5) with 650 m³ of sludge in just 4 days at Aramco Safaniya GOSP-1.
    2. • Completed desludging of a massive 1.25-million-barrel wet crude tank (Tank ID 60-3945) containing 5,000 m³ of sludge in 40 days at Aramco Ras Tanura North Terminal.
    3. • Cleaned a 10,000-barrel slop oil tank (Slop Oil 142) with 125 m³ of sludge in only 5 days at Aramco Ras Tanura Refinery.
    4. • Removed 5,500 m³ of sludge from a 300,000-barrel slop oil tank (Slop Oil 145) in 21 days at Aramco Ras Tanura Refinery.
    5. • Efficiently desludged a 500,000-barrel wet crude tank (Tank ID 60-1140) with 1,300 m³ of sludge over 30 days at Aramco Ras Tanura South Terminal.

Get in Touch:

To proceed with a tailored solution, we would appreciate it if you could kindly provide the following details:
  1. • Crude API gravity – to assess viscosity and sludge behaviour.
  2. • Tank bottom slope orientation – is it sloped from center to shell, or shell to center? This affects the drainage strategy.
  3. • Tank size – diameter and height (or total volume in m³/barrels).
  4. • Estimated sludge volume – to calculate chemical dosage and cleaning time.
  5. • Number and size of dewatering lines – to evaluate fluid management during treatment.
  6. • Current desludging practice – e.g., manual entry, jetting, circulation, steam, or mechanical removal.
Once we receive this data, we can provide a detailed proposal that includes a chemical strategy, circulation plan, and estimated time for cleaning.
