Device for deep recovering light oil from dry distillation gas

Abstract

The invention relates to a device for deep recovering light oil from dry distillation gas. According to the device, gaseous light oil and water vapor in dry distillation tail gas are condensed by cooling the dry distillation tail gas, and the light oil is covered so that a gas calorific value is improved and an enterprise can get large economic benefits. Through a high-efficiency heat exchanger and an oil-water separator used by the device, tail gas is cooled only by the one-grade heat exchanger and then is treated by an oil mist filter, the amount of oil recovered by the high-efficiency heat exchanger and the oil mist filter is basically the same as that provided by the contrast file 1, and a cost of the oil mist filter is much lower than that of the high-efficiency heat exchanger. The oil-water separator independently developed by the company has good separation effects and can acquire high-purity light oil only by one-grade oil-water separation. An intermediate oil tank used by the device guarantees maximal recovery of light oil and prevents light oil volatilization possibly appearing in the contrast file 1.

Description

technical field [0001] The invention belongs to a deep recovery device for light oil in coal, shale oil, petrochemical and other industries, and in particular relates to a deep recovery device for dry distillation gas light oil. Background technique [0002] Due to the acceleration of the world's population and developing countries such as China's industrial process, global energy consumption is growing at a rate of 3%, and this growth rate will likely be maintained for a long time to come. In this case, the world's proven primary energy reserves are expected to be exhausted within 100 years. Therefore, it is imperative to actively develop new energy-saving and consumption-reducing process technology routes around the world. Internationally, coal and oil shale are rich in resources, widely used, and developed and utilized relatively early. However, due to the low price of crude oil over the years, relatively speaking, the cost of producing and processing shale oil is relati...
