Embodiment 1
[0038] In the above full volume 5m 3 Add 3850Kg of ethylene glycol into the reactor, vacuumize the reactor and replace it with nitrogen for three times, then fill the reactor with nitrogen to make the pressure of the reactor reach 0.015MPa, take samples to test and control the oxygen content in the reactor to be less than 100ppm, and then evacuate the reactor to - 0.095 MPa. First use 0.8MPa steam to raise the internal temperature of the reactor from 20°C to 150°C, stop using steam, then use electric heating to raise the temperature of the reactor through heat transfer oil, from 150°C to 180°C, the total time is 2 hours 15 minutes, steam: 796Kg, electricity: 168KW.
[0039] Total cost: 0.796*260+168*0.74=331.28 yuan.

Description
technical field [0001] The invention relates to an energy-saving high-temperature and high-pressure reactor, which belongs to the technical field of chemical production equipment. Background technique [0002] Currently used in high-temperature reactors, especially reactors with a reaction temperature of 180-230°C, the heating method is mainly realized by heat transfer oil heating or electric heating jacket; the heat transfer oil heating method is generally equipped with a heat transfer oil heating system alone, including Heat conduction oil electric heater, heat conduction oil circulation pump and heat conduction oil electric heating temperature control system; the advantage of heat conduction oil heating method is that the temperature control of the reactor is relatively accurate, but the disadvantages are: complex system, large investment, large floor space, and high operating costs . The electric heating mantle heating method is relatively simple, but it has the disadva...
