Production process of batch process of catalytic oil slurry

Abstract

Disclosed is a production process of catalytic slurry oil intermittent machining; the catalytic slurry oil is the raw material and the heat recovery process is added to the production process; the raw material in the heat exchange oil tank is enabled to have heat exchange with a medium heat exchanger on top of the evaporator; the raw material is heated to the temperature of 200 DEG C and then is fed into the evaporator; under pressure of 10-30 mmHg, the material is heated to 200-370 DEG C and machined according to the processes of feeding, heat exchange, evaporation and cooling; the light component is distillated from the top part of evaporator and the rubber processing oil is obtained through the heat exchanger and the condenser; the heavy component is distillated from the bottom of the evaporator and is made into petroleum resin through the condenser. The waste heat is used sufficiently because of the added heat recovery process; the average electricity of the single evaporator production is saved by 15-27%; the production time is saved by 20-30%; the purpose of high efficiency, saving energy and reducing consumption is realized; the frothover problem during the production process is avoided through the addition of the normal pressure heat exchange oil evaporator; thereby, the quality of the product is guaranteed and the hard recovery problem of the unstable high heat flow is solved; the production process of catalytic slurry oil intermittent machining is applicable to the intermittent production of the products in the chemical industry.

Description

technical field [0001] The invention relates to a catalytic oil slurry intermittent processing production process for producing rubber operating oil and petroleum resin by using catalytic oil slurry as raw material. Background technique [0002] Rubber operating oil plays an important role in rubber production and product performance. In order to improve the properties of rubber such as elasticity, flexibility, easy processing, and easy mixing, and ensure the production of high-quality rubber products, a certain amount of rubber operating oil is usually added. Due to different uses and industries, the requirements for the physical and chemical properties of rubber processing oil are different, so there are many varieties of rubber processing oil to meet different needs. [0003] At present, my country's petroleum-based rubber process oil mainly uses catalytic oil slurry as raw material, and adopts batch distillation technology to heat the raw material to 200-370°C in the eva...

Problems solved by technology

[0003] At present, my country's petroleum-based rubber process oil mainly uses catalytic oil slurry as raw material, and adopts batch distillation technology to heat the raw material to 200-370°C in the evaporator, and the light component is separated from the top of the evaporator, and is produced after cooling by the condenser. The heavy components flow out from the bottom of the evaporator to make petroleum resin through the cooler. The heating of the evaporator in the whole production process consumes a lot of energy, and the subsequent cooling process will release a large amount of heat. Failure to recover, the heat is not only wasted, but also exacerbates the greenhouse effect and pollutes the environment
