On the difference between the product yield of crude oil in atmospheric and vacuum distillation units and the actual yield as determined by testing
Thread Content
In the theoretical yield differences for crude oil analysis, the yield of heavy fraction products is roughly the same as that of the products produced in atmospheric and vacuum distillation units. However, the theoretical and actual yields of light fraction oils do not match. Interestingly, the theoretical yield of naphtha is a few percentage points higher than its actual yield, while the theoretical yield of diesel is a few percentage points lower than its actual yield. What’s going on here?

Yes, both the initial distillation tower and the stripping tower have them
In a process with a primary distillation tower, it depends on how you control things: to obtain more diesel, keep the temperature at the top of the column low, increase the amount of recycled heat accordingly, and make other necessary adjustments; the key is to achieve a low flash point
