What conditions must be met for heating the reactor in an phthalic anhydride plant?
We use BASF’s products, and usually experts are available to provide on-site guidance
The question is unclear; why raise the temperature? – Feedstock or salt dissolution? I see you have many questions; actually, the answers are all in the operating procedures, so take a closer look
First, the gas is preheated, followed by molten salt circulation; once a certain temperature is reached, material feeding for production can begin. This technology is already very mature.
Meanwhile, in the phthalic anhydride industry, as already explained clearly above, the air is heated initially through air heating, and then via electric heating.
The heating rate should not be too fast. Keeping it below 10 degrees per hour is sufficient
