Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of reactor equipment, and in particular relates to a heat energy recovery and utilization device for a hydrogenation reactor. Background Art
[0002] The hydrocracking unit belongs to the catalytic process technology of hydrogenation. It is composed of three process modules: reaction, fractionation and desulfurization. The unit adopts a series production process. During operation, the raw oil is first heated, and then it is transported to the reactor, where the hydrogenation reaction is realized. After the reaction, it is transported to the distillation tower, where the fractionation treatment is completed, and then the corresponding gasoline and diesel primary products can be obtained. Then, the purification and desulfurization of the gasoline and diesel primary products are completed again in the unit process, so that the gasoline and diesel products can meet the relevant national quality standards. During the operation of this unit, the stripping tower is mainly used to separate the distillation tower. The key to improving the quality of gasoline and diesel products is to produce products such as diesel and kerosene. It cannot be ignored that during the catalytic cracking process, the finished gasoline contains a certain amount of sulfides. The sources of these sulfides are mainly two aspects. One part is the sulfides existing in crude oil, and the other part is formed in the catalytic cracking process of crude oil (formed by the cracking of long-chain alkylthiophenes and the addition of H2S and olefins and dienes to generate mercaptans and then cyclization). The more common catalytic cracking gasoline hydrodesulfurization processes currently include selective hydrodesulfurization technology and non-selective hydrodesulfurization technology, among which selective hydrodesulfurization technology is more widely used;
[0003] Hydrocracking is a process in the petrochemical industry, that is, during the petroleum refining process, hydrogen is used as a catalyst to hydrogenate, crack and isomerize heavy oil at a relatively high pressure and temperature, and convert it into light oil (gasoline, kerosene, diesel or raw materials for catalytic cracking and cracking to produce olefins).
[0004] However, the current process causes a large amount of water vapor to adhere to the inner wall of the device during processing, and the general way to deal with the water vapor is to discharge it to the outside of the device through the bottom or surface drainage pipes. This behavior undoubtedly wastes processing resources to a certain extent, and the water vapor cannot be used to discharge into the distillation tower for recycling during processing, and the heat energy of the hydrogenation reactor cannot be effectively utilized. Moreover, when the processed product is processed, the processed product is easily attached to the inner wall of the device, and the user is required to regularly clean the residue on the inner wall, which is time-consuming and labor-intensive, and increases the workload of the user. Based on this, we propose a heat energy recovery and utilization device for a hydrogenation reactor, which has the function of facilitating processing and is urgently in need of development.
