Hydrogenated decomposition and separation system for intermediate composition oil of petroleum

Abstract

The invention relates to petrochemical engineering equipment and in particular relates to a hydrogenated decomposition and separation system for intermediate composition oil of petroleum. The hydrogenated decomposition and separation system comprises a thermal oil furnace, a hydrogen compressor, a feeding pot, a desulfurizer, a hydrogenator, a hydrogen tank, a hydrogenation solution heater, a reaction tower, a reaction solution heater, an adsorption tower, a high-separation tower, a macromolecular solution heater, a fractionating tower, a gasoline cooler, a refined diesel cooler, a heavy diesel cooler, a gasoline circulating tank, a refined diesel circulating tank, a heavy diesel circulating tank and a tail oil circulating tank. The hydrogenated decomposition and separation system has the advantages of simple production process, short flow path, low energy consumption, labor saving, occupying land saving, low investment, high effect-taking speed and the like. The hydrogenated decomposition and separation system can be used for refining gasoline and diesel with high quality from the intermediate composition oil of the petroleum, thereby solving the problem of deep processing of the intermediate composition oil of the petroleum and saving a great deal of petroleum resources. Therefore, the hydrogenated decomposition and separation system has the advantages of obtaining favourable economic and social benefits and powerfully promoting the development of the oil industry in China.

Description

technical field [0001] The invention relates to petrochemical engineering equipment, in particular to a hydrolysis and separation system for petroleum intermediate oil. Background technique [0002] In the process of petroleum refining, a part of intermediate oil (light oil, non-standard oil, etc.) will be decomposed. Since large-scale oil refining manufacturers cannot solve the problem of intermediate oil refining, they have not been able to solve the problem of non-standard oil for many years. The re-refining technology of standard oils has led to the intermediate oils being purchased by some small and medium-sized manufacturers and put into the market after simple decolorization treatment, which is used as so-called gasoline, diesel and other fuel oils. The quality of this product does not meet the national standards, such as flash point, sulfur content, ash content, freezing point and other indicators are not up to standard. The composition of petroleum intermediate oil...
