Chemical equipment is the equipment for all chemical reactions. The correct and reasonable operation and use of chemical equipment is an important measure to ensure safe operation. Even if the planning of the equipment completely meets the requirements, the production and equipment are of good quality. If the operation is not performed properly, the same will happen. Something.
Chemical equipment is the primary equipment in the petrochemical production process. The operator must understand the process flow of the post, the structure and category of the relevant container, the primary technical parameters and technical functions, and strictly follow the operating procedures. Grasp the method of handling general incidents and fill in the relevant records carefully.
During the operation of chemical equipment, the pressure frequently changes and greatly shakes, which is unfavorable to the fatigue resistance of the equipment. The operating pressure should be kept as stable as possible. At the same time, during the operation of chemical equipment, the sudden change of the shell temperature should also be avoided to avoid excessive temperature stress.
When loading and unloading chemical equipment, the speed should not be too fast to avoid the adverse effects of rapid changes in pressure or temperature in a short time. To avoid overloading of chemical equipment, the first thing is to avoid overpressure. It is necessary to strictly control the feed volume and reaction temperature to avoid overpressure in the container due to the reaction out of control. When the storage container is filled with materials, it is necessary to measure strictly, to avoid overfilling, and to avoid thermal expansion of the material and overpressure of the equipment.
During the operation of the container, chemical equipment operators should constantly supervise the work situation, find out the abnormal situation in operation in time, and adopt corresponding measures to ensure safe operation. The supervision and control of the operation of chemical equipment is mainly carried out from the aspects of process conditions, equipment conditions, and safety equipment.
The safety equipment of chemical equipment must be intact. Firstly, check the integrity of the safety accessories and metering appearances, such as whether the appearances are inaccurate or blocked; whether the interlocks and alarms are reliable and put into use, and whether the outdoor equipment is in the promised period of use. Is it frozen? Once an abnormality occurs, it must be stopped urgently.
