What are the reasons for the increase in temperature in an alkylation contact reactor?

I have never operated an alkylation unit, and theoretically there are the following possibilities: 1. It could be that uneven mixing due to boredom led to direct polymerization of the olefins, resulting in high heat release; 2. The cooling effect of the refrigerant is insufficient; 3. The stirring speed is not appropriate, causing excessive local heat release; 4. The water content in the material is high or the sulfuric acid concentration is low, leading to more side reactions; 5. The alkene to olefin ratio is too low

The main reason should be the high heat release, I guess

1. High pressure in the flash tank； 2. Low refrigerant flow rate ； 3. The olefin content in the raw material suddenly increases.
