Seeking a Crude Oil Sludge Dewatering System with Water Treatment & Reuse

In the Chemical & Energy industry, crude oil storage tanks require periodic cleaning to remove heavy sediments and sludge accumulated at the tank bottom. This process involves the use of ultra-high-pressure water jets and vacuum suction to remove the washing sewage which largely comprises of sludge, oil, and water. The waste products are then sent via tanker trucks for disposal and incineration.

As water is a significant constituent of this waste, being able to reduce the water content from the cleaning waste will be advantageous, providing a significant reduction in transportation and overall disposal costs.

A Singapore-based company is seeking a system to separate water (dewater) from sludge, and further option of incorporating in-line water treatment means including volatile organic compounds (VOCs) and pH treatment. The treated water is to be re-directed by the system for reuse as cleaning water via ultra-high-pressure jets.

Collaboration is sought with companies experienced with sludge dewatering, and capable of system integrating the water treatment and reuse functions. The preferred collaboration mode is to co-develop a POC system for evaluation, before scaling up for operations.

1. Oily sludge dewatering system with option of water treatment system for reuse and recycle
2. Sludge waste after tank cleaning consists of oil, solids and water. Of which, water can take up to more than  50% of the overall composition.
3. Proposed system should remove at least 60% water from sludge and be integrated with existing tank cleaning protocol
4. Treated water should be treated to be fit for reuse for tank cleaning operations with particle size in water to be < 5 micron
5. Proposed solution must be compact and not larger than a standard 20 foot container for mobile deployment 
6. Proposed solution should have a consistent throughput of 10 metric tonne per hour

1. Compression methods, filter presses
2. Overly complicated water treatment technologies
3. Solutions that require batch processing for water treatment
4. Proposed technology should be fit for use and cost effective
