What are the characteristics of chemical plant maintenance?

The maintenance of chemical equipment is characterized by complexity and danger.

Description:

Its complexity is manifested in many maintenance projects, complex maintenance contents, heavy construction workload, concentrated tasks, short maintenance time, many personnel, frequent changes in operation forms and workers, frequent overtime in order to catch up with the construction period, and a wide variety of chemical equipment with different structures and performances.

The maintenance of various types of work up and down the tower and inside and outside the container is limited by environmental and climatic conditions, which increases the complexity of equipment maintenance and is prone to personal injury accidents.

The danger of chemical production determines the danger of chemical maintenance. Because there are flammable, explosive and toxic substances in the equipment and pipelines of chemical plants, and the maintenance of the factory can not be separated from operations such as starting fire, breaking ground and entering tanks, there are objectively factors that cause accidents such as fire, explosion and poisoning. If it is not handled properly, it is easy to have a major accident.

Brief introduction of chemical plant;

Chemical plant refers to the equipment system used to produce chemical products. It usually consists of several different unit operations, each of which has its own specific tasks and functions. These unit operations may include reactors, separators, heaters, condensers and pumps.

Matters needing attention in chemical plant maintenance:

1, make a maintenance plan.

The maintenance department shall formulate a maintenance plan including maintenance objectives, scope, standards and requirements, and conduct safety inspection and risk analysis on all links of maintenance operations. Safety inspection and risk analysis can be carried out by job hazard analysis and safety checklist, so as to identify potential risks and formulate relevant safety measures to ensure the safety of maintenance work.

2. Ensure the safe working conditions of the equipment.

Before overhaul of chemical equipment, stop according to the scheduled parking plan, and cut off the power supply and all media sources; The materials in the equipment should be completely emptied according to the predetermined scheme; Equipment with toxic, harmful, flammable and explosive gases should be replaced with inert gas.

Before entering the equipment, the concentration and oxygen content of combustible gas, toxic and harmful gas must be detected, and the operation can be carried out only after it is qualified.

3. Wear labor protection articles correctly

When working in chemical equipment, operators should wear labor protection articles correctly according to the results of risk analysis to ensure effective protection. If you are in inflammable and explosive equipment, wear anti-static overalls to prevent electrostatic sparks or corrosive substances from contacting the skin; The helmet must ensure that the hat strap is fastened.
