CLEANING OR DE-SLUDGING A CRUDE OIL TANK OR LAGOON IS ONE THING. HOW TO RECOVER THE GOOD OIL FROM THE SLUDGE?OIL RECOVERY FROM THE SLUDGE IS THE ANSWER

The solution is The TS150 which recovers the good oil from the sludge leaving dry cake sediment and water using superior technology with our decanter centrifuge with full Viscotherm drives of bowl and scroll. A mobile system built into 20ft certified shipping containers for ease of transport.

all hydraulic centrifuge with viscotherm — all containerized system

The processing rate can vary. It depends on the incoming quality and desired outgoing quality. A general rule is 10-15m3 is a normal throughput giving good results

Recovered oil will contain 2% or less BS&W and the Sediment or solids remaining after processing will have 100ppm or less of leach-able hydrocarbons.

The TS150 portable sludge treatment unit is a specially designed and fabricated system, of heavy-duty, welded construction built into special certified shipping containers.

The centrifuge unit has been purpose-built into a 20ft container for safe operation and maintenance and is all Hydraulic Viscother drive of the bowl and the scroll giving automation and ability to alter the speeds.

All electric motors and the system control panel are rated EExd for Zone 1 refinery use and are 3 phase with 50 or 60hz power supply.

The TS150 unit includes:

A screen shaker to remove any solids that could damage the system

A heated pre-treatment system with a heavy-duty electric drive agitator is used for effective re-circulation and re-suspension of solids in the sludge. The pre-treatment tank has a large external level indicator and high/low-level alarms.
An electric drive agitator is used to effectively re-circulate and re-suspend solids in the sludge. The pre-treatment tank has a large external level indicator and high/low-level alarms
Heavy-duty, variable-speed electric drive Centrifuge Feed Pumps. The main pump plus standby pump is hard piped and wired into the control system for continuous working.
Chemical Dosing System for improved performance and treatment of a wide range of waste oil sludge materials. The system includes mixing and holding tanks with electric drive agitators and variable-speed dosing pumps.
Centrifuge supplied complete with sediment and recovered oil chutes.
Purpose-built, heavy-duty two-phase Centrifuge to remove solids from the pre-treated sludge and reclaim good quality oil suitable for pumping directly back to refinery storage facilities. Centrifuge system includes comprehensive control and alarm systems wired into the system Control Panel
Purpose-built centrifuge built into a special 20ft container which allows safe access around centrifuge for routine maintenance.
Electrically driven VISCOTHERM Power Pack for centrifuge bowl and scroll drive and control. Unit wired into the centrifuge control panel for safe and simple operation.
Recovered Oil Holding Tank (3.5m3) with large external level indicator and high/low-level alarms.
Heavy-duty, variable speed electric drive Sludge Feed Pump for sludge feed.
Heavy-duty, variable-speed electric drive Recovered Oil Pump to transfer reclaimed oil into adjacent storage tanks or directly back into the refinery system
All equipment is wired into the main Control Panel for safe and simple operation. All feed pumps stop/start wired into integrated high/low-level alarms.
System is designed for on-site operation in remote locations and has all maintenance items easily accessible.
