As one of the hazardous chemicals, the phosgenation process has dangerous characteristics. Phosgene is a highly toxic gas. If leaked during storage, transportation and use, it can easily cause large-scale pollution and poisoning accidents; the reaction medium has the risk of explosion; the by-product hydrogen chloride is corrosive and can easily cause leakage of equipment and pipelines. Cause poisoning accidents to people.
Many of the causes of production safety accidents are employees' low safety awareness and weak safety prevention capabilities. Therefore, it is extremely important to carry out phosgenation process training.
Obel Chemical Training Base has a phosgenation process training device and is equipped with professional training courses to help companies carry out phosgenation process training.
Phosgenation process training device
process training:
The carbon monoxide from the carbon monoxide dryer and the chlorine from the liquid chlorine supply tank are mixed in the feed mixer in a certain proportion. The gas mixture enters the top of the phosgene synthesizer. There are 2 phosgene synthesizers, 1 on and 1 on standby, to ensure that production will not be affected when catalyst fails and is replaced. The phosgene synthesizer is a shell-and-tube type, and the tube is filled with coconut shell activated carbon as a synthesis catalyst. Thermal oil is used as coolant on the shell side, and the thermal oil passes through. The reaction gas from the phosgene synthesizer enters the clean reactor. Under normal circumstances, all chlorine is reacted in the phosgene synthesizer. The purification reactor only plays an insurance role to ensure that all chlorine is reacted. The phosgene coming out of the clean reactor is sent to the subsequent phosgenation process.
phosgene thermal nitrogen system consists of nitrogen heater. Hot nitrogen is used to purge phosgene synthesis process equipment and pipelines during shutdown. Purge the phosgene synthesis process equipment and pipelines in sections. The purged waste gas is sent to the waste phosgene alkali washing tower for treatment. The purge ends when the phosgene concentration in the analyzed exhaust gas is lower than the set value. The exhaust gas from the phosgenation reactor is dechlorinated by the alkali solution and then discharged to the torch at high altitude.
