Abstract copyright Andrew W. Sloley

Both product pipeline operation and terminal blending often generate slops consisting of mixed hydrocarbon streams. Typical slops dispositions include local burning of the fuel for heat or power generation or reshipment to a refinery in a crude stream. Both of these dispositions can incur significant economic penalties.

An alternative is the use of a small local plant for the separation of the streams back into pipeline products. This is achievable as long as blend stocks rather then final products containing performance additives are being separated. Final products (gasoline, diesel) contain additives and blending components difficult to handle within the constraints of a small process unit.

A proposed multi-product separation unit is presented. The case investigated shows the process configuration required for a unit to process a range of mixtures containing material from LPG to atmospheric gas oil. The material presented includes the plant flow scheme, identification of major equipment, and overall sizing of major equipment. The study results summarize the investment and operating costs of the unit compared to the values of the recoverable products.
