In coal tar hydrogenation, the pressure difference is high; the water injection volume needs to be increased. How to address the situation where the pressure difference doesn’t decrease?

What is exchanging heat with what, is coking occurring? Increase the number of bypasses to see if there is an improvement
Scaling and ammonium salt crystallization lead to high pressure differences in heat exchangers
Use a polymerization inhibitor to prevent scaling; water should be injected before the heat exchanger, and the temperature before heat exchange must be above 240 degrees. Monitor chloride ions as well
