| Abstract | A 2.7 m3/h capacity compact plate separator (CPS) pilot-plant was developed to study the practical engineering aspects and economics for possible future development of the unit at commerci.al scale.· Investigations were carried out in comparison to the API's conventional oil-water
separator generally regarded as a standard device for physical treatment of oil-wastewater. The API unit is an expensive option with limited scope to handle the emulsified oil-wastewater and has many operational
difficulties. The unit is often supplemented with sophisticated steam heating emulsion breaking system and mechanical sludge scrapers. In
developing CPS unit, need for steam-heating and mechanical scrapers was eliminated by provision of a simple direct-fired emulsion breaking system
and semi-automatic sludge knockout arrangement. Pilot-plant operation at 1.5 m3/h, 2.7 m3/h, and 5.5 m3/h flow rates
demonstrated ·almost uniform effluent quality by successfully handling the petroleum wastewater (free oil and temporary emulsions) containing up to 6,000 mg/t oil and about 1,000 mg/t SS. For all three flow rates oil level in effluent was found to be less than 10 mg/t. Similar results were obtained with palm oil wastewater containing up to 1,200 mg/t oil.
Economic study revealed that a commercial CPS unit may be developed by a nominal fixed capital investment as compared to the investment required for an API unit of the same capacity. Annual operation cost was
found to be about one half of the expense needed for API unit. |
