Reduction of Oil Losses from Evaporation at Oil Collection Points

Abstract

Abstract During the filling and emptying of the tanks at the oil collection points, the transfer of petroleum products from one tank to another, and the storage of petroleum products in tanks, evaporation losses of petroleum products occur, and ecology and the environment are polluted. In order to reduce evaporation losses in the tanks, the gas spaces should be connected with the collector pipe. For the condensation of oil vapors, the collector connecting the gas spaces of the tanks should be connected to the drainage capacity by passing through the overflow crude oil collection or formation water collection tanks. Steam passing through the tank condenses as a result of cooling. Ecology and environmental protection are the most important issues in the collection, transportation and storage of extracted oil and gas. Ecology and environmental protection is about reducing losses in the transportation and storage of oil. There may be quantity and quality losses in petroleum products. In quantitative losses, the consumption of petroleum products increases, and in quality losses, their composition changes. Quantitative losses are caused by leaks in the flange joints of fittings, pump casings, erosion of tanks and pipes during transportation of oil products, as well as evaporation of oil products in tanks. Evaporation losses account for 75% of total losses [1]. Evaporation losses of petroleum products occur as they are stored in tanks, filled and unloaded, and transported from one tank to another. In tanks filled with petroleum products, a complex evaporation process always occurs, resulting in oil losses. Oil losses are inevitable during the "breathing" of tanks [2, 3]. Small "breathing" is accompanied by the temperature difference between day and night, and large "breathing" is accompanied by filling the tanks with petroleum products.
