Alkylation product isooctane
Thread Content
The product octane contains olefins. What are the reasons and the impacts?
Is there a leak in the heat exchanger causing issues with the reaction feed and output?
The separation tower doesn’t separate well, or some olefins are leaking into the product
The reaction is not complete, which is why the samples taken from the isobutane removal tower are of substandard quality; this is also a very important indicator. Indicators for regulating reactions
There are two reasons for this: first, the empty space velocity is too high during the DuPont process; second, there is a problem with the condition layer in the Lumas process
Common causes include: 1. The device is operating under overload conditions, with too fast a space velocity resulting in incomplete reactions； 2. Uneven reaction due to filler skew flow in the reactor bed of the LUMMUS process ； 3. Leakage within the heat exchanger tube bundle between the reaction products and the feedstock; the feedstock olefin enters the reaction product system ； 4. Malfunctions of analytical instruments, etc.
