Embodiment Construction
[0023] use Figure 1-Figure 3 The efficient styrene production process of one embodiment of the present invention is described as follows.
[0024] Such as figure 1 and figure 2 Shown, a kind of chemical product production process optimization method described in the present invention, this process comprises the steps:
[0025] S1: Pass ethylbenzene into the ethylbenzene dehydrogenation reactor, and put a catalyst in the ethylbenzene dehydrogenation reactor, so that the ethylbenzene dehydrogenation reaction occurs;
[0026] S2: After ethylbenzene is introduced into S1, a high-temperature water steam boiler is installed, and the high-temperature steam generated in the boiler is passed into the ethylbenzene dehydrogenation reactor, so that the high-temperature steam heats ethylbenzene and dehydrogenates ethylbenzene The crude product of styrene is obtained and heated with water vapor, so that while the ethylbenzene is heated and reacted, the water vapor reduces the pressure ...

The invention belongs to the technical field of styrene production, and more specifically relates to a chemical product production technology optimization method. The chemical product production technology optimization method comprises following steps: ethylbenzene is introduced into an ethylbenzene dehydrogenation reactor, and a catalyst is introduced into the ethylbenzene dehydrogenation reactor, so that ethylbenzene dehydrogenation reaction is carried out; a high temperature steam boiler is adopted, high temperature water vapor generated in the high temperature steam boiler is introduced into the ethylbenzene dehydrogenation reactor for heating of ethylbenzene, so that a styrene crude product is obtained through ethylbenzene dehydrogenation; a heat exchanger used in petroleum chemistryis adopted for heat exchange and cooling of the styrene crude product, water is taken as a cooling medium, at the same time, a pipeline is used for communicating a liquid outlet of the heat exchangerused in petroleum chemistry with a liquid inlet of the high temperature steam boiler, so that the high temperature steam boiler is provided with heated water; the styrene crude product is introduced into a styrene distillation column so as to obtain refined styrene. The chemical product production technology optimization method is suitable for large batch production of styrene, and is low in production cost.
Description
technical field [0001] The invention belongs to the technical field of styrene production, in particular to a process optimization method for chemical products. Background technique [0002] Styrene is an organic compound formed by replacing one hydrogen atom of ethylene with benzene. The electrons of the vinyl group are conjugated with the benzene ring. It is insoluble in water, soluble in ethanol and ether, and gradually polymerizes and oxidizes when exposed to air. Industrially, it is an important monomer for synthetic resin, ion exchange resin and synthetic rubber. Styrene is widely used in industries such as automobiles, home appliances, medicine, dyes, pesticides and mineral processing. With the development of society, the use of styrene The demand is increasing, but the existing styrene production process is low in efficiency and high in cost. How to improve the production efficiency of styrene and reduce the production cost of styrene has become a problem we need to ...
