Saturated chlorine capacity of the reforming pre-hydrogenation high-temperature dechlorination vessel
Thread Content
The unit has been operating at low load for 3 years; the two dechlorination tanks in the process are connected in series as A-B, and regular samples taken from the high-temperature dechlorination stage show a chlorine content of less than 0.5PPM； It always seems necessary to replace the tank; in theory, it’s possible to replace it while it’s still in use, but the valve has internal leakage issues ； There is no data to support the replacement, so there is no basis for it, and there is also concern that the operation cycle will become saturated next year. Questions: 1. Is there a specific formula for calculating saturated chlorine capacity, and how to use it? 2. What is the model of the dechlorination agent JX-5A?
This is related to the chlorine content of your raw materials. If you always use raw materials with a high chlorine content, while the filling volume is designed for materials with low chlorine content, then it will be necessary to replace the catalyst between cycles of operation. Under constant pressure and temperature, the usage time is related to the chlorine capacity of the dechlorinating agent, the filling height, the chlorine content in the raw material, and the feed rate
Saturation chlorine capacity is a property of the catalyst; generally, catalyst manufacturers will not provide you with such formulas
