How should sudden increases in water content in the gas caused by moisture in the reformation feed be handled? (In continuous reforming units) What emergency measures should we take when an increase in water content in the reforming feed leads to a sudden rise in water levels in the gas? What steps should be taken to achieve the best results? (It is best to explain the detailed operations for specific devices.)
Lower the reforming reaction temperature and increase the chlorine injection rate; resume normal operations once the water content in the gas returns to normal
It affects the water-chlorine balance and metal function. Try to reduce the reaction temperature, control the amount of coke formation, and pay attention to regeneration. There’s no need to take action regarding chlorine supplementation for now; just keep an eye on it. Pay attention to the HCL content of downstream equipment.
It depends on how high the water level in your gas is
In general, the water content in crude oil is no more than 0.5PPM. Find out the reason for the high water content in the gas; if the water level is too high, the reforming reaction temperature must be reduced ； The reflux tank at the top of the dehydration tower enhances dehydration; in addition, it is necessary to ensure stable operation ； If the water content in the pre-hydrogenation feed is high, dehydration should be enhanced in the tank area ； Put the molecular sieve into use ； Stop the water injection, and add chlorine in an appropriate amount depending on the level of water present. Keep in mind that if the water content is too high, it is necessary to lower the temperature to prevent this; at high temperatures, the platinum crystals in the catalyst grow, causing permanent damage to the catalyst
First, the water supply must be cut off; if necessary, the feed for the reforming process should be changed. Then, the reaction temperature is reduced to 480 degrees, and chlorine is added according to the specified schedule
