1. Main manifestations of illegal work
If the stainless steel reaction kettle is not replaced or the replacement is not complete, the test run or the manhole is opened for welding maintenance, and the air enters the kettle to form an explosive mixture and explode. Use flammable gas (such as the refining gas of the synthesis system, the shift gas of the carbonization system) to make up the pressure, test the pressure, and test the leak. Hot work is carried out without hot fire analysis and hot treatment (such as no blind plate is added to isolate the maintenance equipment from the production system, or the quality of the blind plate is poor, or asbestos plate is used as the blind plate), and the hot work is carried out without a hot fire certificate. Bolts for valves and flanges of pressure-tightening equipment. Blind pursuit of output, overpressure, overload operation. Unauthorized lowering of the liquid level in the storage tank makes the water seal ineffective or the positions do not cooperate well, causing the compressor and pump to be pumped negatively, allowing air to enter the equipment to form an explosive mixture. The change of process parameters in the equipment was not detected in time when the equipment was in operation, resulting in the explosion of oxygen in the system.
2. The main types of operational errors
When the equipment is replaced and cleaned, the replacement sequence is wrong. Staggering the valve during operation, or not opening and closing the valve in time, or the wrong sequence of opening and closing the valve, will cause the equipment to hold back pressure or the gas to flow back and overpressure, causing a physical explosion. Feeding too fast or feeding unevenly causes a sharp increase in temperature, or solidifies the mother liquor in the equipment. Failure to discharge condensed water in time or improper operation will cause the equipment to operate with water overpressure. Compressor and pump suction caused by operational reasons allows air to enter the equipment and form an explosive mixture. Prematurely stopping the pump and water will cause local overheating, melting and perforation of the equipment. Throwing the wrong material will cause it to decompose and explode in the recycling process. Staggering the outlet valve of the oil tank will cause the roof to overflow and explode in case of an open fire.
