What should be the maximum level of chloride ions in coal tar hydrogenation, and what are the hazards if this level is too high? Can it be controlled?
Control the raw materials; keep the chlorine level below 20
There should be clear requirements in the device’s setup instructions, right? If it is too high, it will accelerate corrosion and raise the crystallization temperature of ammonium salts. Hydrogenation alone cannot adjust the chloride ion content; it is necessary to address the upstream processes in order to control the quality of the raw materials
Stainless steel corrosion is most severely affected by chloride ions, as well as ammonium chloride crystals. If the chloride ion content is high, a dechlorination tank can be added. You can refer to the indicators for desalinated water, such as the sulfur content of chloride ions in the water. It’s okay to order a little extra occasionally.
It is mainly to prevent corrosion of the equipment
