Embodiment 1

[0021] Adopt the method for condensation reaction of energy-saving type dicumyl peroxide DCP device of the present invention, the production scale of DCP industrial device is 200 tons / year. First add 0.22 tons of 100% hexanaphthene material (1) in condensation kettle (100), then add condensation after 0.023 tons / hour dimethyl benzyl alcohol and 0.052 tons / hour cumene hydroperoxide (2) meter Kettle (100), the operating temperature of the condensation reaction is 42°C, the operating pressure is 0.001MPaG, the condensation reaction heat is 21.3 kilowatts, absorbed by cyclohexane, cyclohexane itself vaporizes and enters together with the water vapor (3) generated by the reaction Condenser (200), the cooled and condensed material (4) enters the oil-water separator (300) for oil-water separation, the cyclohexane material (5) returns to the condensation kettle (100) for recycling, and the process water (6 ) is thrown out of bounds. Due to the adoption of the technical means of cyclo...

Embodiment 2

[0025] According to the conditions described in Example 1, only the production scale of the DCP industrial plant was changed to 1000 tons / year. Add 1.12 tons of 100% cyclohexane into the condensation kettle, then add 0.114 tons / hour of dimethyl benzyl alcohol and 0.259 tons / hour of cumene hydroperoxide to the condensation kettle, the operating temperature of the condensation reaction is 42 ° C, the operating pressure It is 0.001MPaG, and the condensation reaction exotherm is 106 kilowatts. Due to the adoption of the technical means of cyclohexane vaporization and absorption of reaction heat of the present invention, the method of nitrogen bubbling is avoided, and the energy consumption of the DCP unit is reduced by 212.4 tons of standard oil per year.

Embodiment 3

[0029] According to the conditions described in Example 1, only the production scale of the DCP industrial plant was changed to 20,000 tons / year. Add 22.3 tons of 100% cyclohexane to the condensation kettle, then add 2.27 tons / hour of dimethyl benzyl alcohol and 5.18 tons / hour of cumene hydroperoxide to the condensation kettle, the operating temperature of the condensation reaction is 42 °C, and the operating pressure It is 0.001MPaG, and the condensation reaction exotherm is 2127 kilowatts. Due to the adoption of the technical means of cyclohexane vaporization and absorption of reaction heat of the present invention, the method of nitrogen bubbling is avoided, and the energy consumption of the DCP unit is reduced by 4248 tons of standard oil per year.

Abstract

The invention relates to an energy-saving type dicumyl peroxide (DCP) device condensation reaction method and mainly aims to solve the problem of high energy consumption of the device in the prior art. The energy-saving type dicumyl peroxide (DCP) device condensation reaction method comprises the following steps: firstly adding a certain amount of one or several mixed material of cyclohexane, hexane, benzene or methylbenzene into a condensation kettle, then adding dimethyl-benzyl carbinol and isopropylbenzene hydroperoxide into the condensation kettle to carry out condensation reaction, sucking heat released by the condensation reaction by one or several mixed material of the cyclohexane, the hexane, the benzene or the methylbenzene, vaporizing, introducing one or several mixed material of the cyclohexane, the hexane, the benzene or the methylbenzene into a condenser together with the steam generated by the reaction, condensing mixed gas into liquid, introducing the liquid into an oil-water separator for separating, returning oil phase of one or several mixed material of the cyclohexane, the hexane, the benzene or the methylbenzene to the condensation kettle to recycle. Through the technical scheme of discharging water phase which is process water generated by the reaction, the problem can be effectively solved; the method can be applied to the dicumyl peroxide (DCP) device condensation reaction.
