Abstract

The need for energy in the world is increasing day by day, and accordingly the search for new energy sources continues. Although the interest and investment in renewable energy has increased recently, the use of nonrenewable (fossil-based) energy resources still maintains its top position. Among fossil energy sources, it is inevitable that the importance of petroleum, which is the most preferred and consumed, will increase. In this case, it is important to benefit as much as possible from the petroleum that is already extracted to the surface at high costs. Petroleum extracted to the earth; Since it consists of a mixture containing water, mud and some gas, it is first crash at high speed against the plates placed horizontally in the tank and kept in the relevant tank for a certain period of time. By this method, separation of most of the gas and sludge in the mixture is achieved. This process is called the first process, and as a result of this process, crude petroleum, separated water (wastewater), sludge, and gas are obtained. The obtained separated water may contain 20%-5% petroleum. Some processes are applied within the scope of the second process to separate this petroleum in the waste water. In this study, within the scope of the second process, corrugated plates were used based on the gravitational separation method, which is widely preferred because it does not require any energy source in the separation of petroleum in waste water and provides separation to a large extent. In order to consider the effect of corrugated plates on the separation efficiency, 3 (three) different hole diameters (15, 35, 55 mm) and 3 (three) different plate lengths (600, 800, 1000 mm) parameters were considered. Also the individual and compound effects of each parameter on the separation efficiency were examined. In all experiments, the same petroleum-water mixture samples (88% water, 12% petroleum) were used and the temperature of the relevant
samples was kept at 23 °C. The change in the separation efficiency of the petroleum-water mixture pumped
into the separation system at a constant flow rate of 20 liters/minute was examined according to the parameters.
The petroleum/water ratio of the mixture pumped into the system and the petroleum/water ratio of the water
separated from the system were measured, and the difference between the two measurements was considered
as the separation efficiency. As a result of the measurements, it was seen that each parameter considered
affected the separation efficiency both individually and relatively. It was observed that the highest separation
efficiency of 98.75% was obtained when the plate hole diameter was 55 mm and the plate length was 800 mm.
