Deoiling plants
LIQUID/LIQUID SEPARATION BY COALESCENCE PROCESS
The plants we design for liquid/liquid separation are based on mechanical-physical effects. Depending on the application or specific requirement, separation takes place in a single- or multi-stage pressure system.
By using special materials, efficient phase separation of liquids and emulsions is achieved. The respective liquid phases can then be continuously discharged from the system for reuse or disposal. Depending on the application and solids content, the de-oiling system can be extended to include a pre-filter/intermediate filter.
Our facilities
With the aid of two stages of SPO and SCO connected in series, the oil phase is reliably separated from the bilgewater occurring on ships, but also from industrial wastewater. A fine filter is used as an intermediate stage to protect the coalescing elements.
The respective required limit and discharge values for the residual oil content of the discharged medium must be complied with. In shipping, for example, the residual oil content of 15 mg/l required by the IMO applies (according to IMO MEPC.107(49)).
Function & Design:
Depending on the application and requirements, our deoiling system consists of one or two pressure vessels equipped with our core technologies "SPO / SCO".
In the SPO stage, small oil droplets are combined by an optimized coalescence process by means of separation profiles to form larger droplets which, due to the difference in density between oil and water, rise into the oil collection dome and are controlled from there via the system pressure. At the same time, dirt particles in the medium are separated into corresponding sludge compartments due to gravity and the directed flow, so that we speak here of a so-called three-phase separation. The second stage SCO serves to separate the remaining smallest oil droplets, mostly emulsions, in a special fiber bed of the coalescer elements used.
The combination of multiphase separation profiles and coalescer elements guarantees compliance with the requirements. The fully automatic plants are mounted on a base frame, completely piped internally and wired to the control system. As components such as valves, feed pump and sensors are also integrated, the customer is provided with a plug & play installation. In addition, customized solutions can be offered for any industrial application.
Advantages:
- fully automatic and wake-free operation
- compact and robust design
- very efficient separation performance, even at high loads in the system inlet
- no use of chemicals and additives
- low operating costs
- low maintenance
