Alkylation consumes a large amount of acid
Thread Content
These days, the acid consumption by the device has suddenly increased. Additionally, the reaction products contain acid, and there are hydrocarbons present in the acid. I hope everyone can help by analyzing this situation
Go and check your coalescers to see if there are any issues affecting the acid-oil separation efficiency
There is significant physical and chemical acidification. 1. Check whether the impurities in the raw materials exceed the specified limits. 2. Pay special attention to butadiene, water, propylene, and alcohols in the raw materials. 3. Determine whether the acid-oil interphase detector is functioning properly; clean it using a flushing solution. 4. Assess the effectiveness of the acid-oil separation process. 5. Check whether the acid circulation rate is too high. 6. Verify whether the reactor temperature is too low, which may result in poor separation efficiency
There are many reasons for the acidic nature of the reaction product: the reactor operating beyond its capacity, problems with the acid sedimentation tank resulting in poor separation efficiency, and leaks in the external heat exchange tubes
