RE: refineries



Dana --

though you may need to use a specialist to help you with the methodology, if
the refinery has not already done so they should consider evaluating the
plant using the so-called "Pinch" technology (see for example,
http://www.linnhoffmarch.com/Resources/WhatIsPinch/pinint1.htm).  The method
was pioneered by B. Linhoff, but has been applied and extended by numerous
others and is essentially a thermodynamic analysis method for identifying
opportunities for heat recovery in complex process plants.   This can often
be a very effective means of identifying significant energy use reductions
in plants, and has the advantage of a fairly high degree of industrial
acceptance.

And although it was NOT written with refineries specifically in mind, the
following articles
from ChemAlliance have some suggestions for P2 in Chemical Process Plants.
Several of them are applicable to a refinery environment.

Subject: refineries


I will be visiting two oil refineries next week to conduct energy
efficiency and pollution prevention assessments.  As of yet, I do not
know a lot about the equipment and practices involved in the refining
process.  Any information regarding potential improvements that can be
made in the process, or ideas on what I should look for during the
assessments (P2 and E2 opportunities) would be a great help.
