Problems solved by technology
[0005] At present, my country's desulfurization of oil products is mainly based on hydrodesulfurization devices. Although this device can reduce the sulfur content in fuel oil, it is still limited by chemical reaction conditions, requires high temperature and high pressure, is easy to corrode, and the device occupies a large area. The input cost is high, and it is difficult to achieve deep desulfurization, and it is difficult to realize industrialization in refineries

The invention discloses low-temperature normal-pressure fuel oil desulfurization and purification equipment and a desulfurization and purification method thereof. The fuel oil desulfurization and purification equipment comprises a pretreatment device, a desulfurization reaction device, a centrifugal extraction and separation device and a by-product recycling device; structures of the desulfurization reaction device, the centrifugal extraction and separation device and the by-product recycling device are improved respectively, fuel oil sequentially passes through the pretreatment device, the desulfurization reaction device and the centrifugal extraction separation device to obtain desulfurized fuel oil, and by-products pass through the by-product recycling device. The desulfurization process is mild in reaction, the reaction is carried out under low-temperature and normal-pressure conditions, reaction is mild, the desulfurization efficiency is high, the safety is high, and industrialization is easy to realize.
Description
technical field [0001] The application relates to the technical field of fuel oil desulfurization, in particular to a low-temperature atmospheric-pressure fuel oil desulfurization purification equipment and a desulfurization purification method thereof. Background technique [0002] Ships are the main mode of global trade and transportation. With the rapid development of the world economy, the pollution caused by ships is becoming more and more serious. Taking oil pollutants as an example, the proportion of pollution caused by ships is as high as 45%. According to the data of the International Maritime Organization (IMO), ships emit 6.34 million tons of SOX annually, accounting for about 4% of the world's total emissions. Under the background of increasingly stringent environmental protection requirements, low-sulfurization and lightweight fuel oil has gradually become a major trend. [0003] At present, low-sulfur fuel oil desulfurization units at home and abroad are mainl...
