Abstract
This paper presents the load problem table (LPT) a numerical technique to
establish the minimum water, wastewater targets
and the pinch locations for continuous water using processes.
The LPT has been adapted from the numerical technique problem table analysis
(PTA) in heat integration and composition interval table (CIT) in mass
integration . The LPT which is tabulated in nature, has overcome the tedious
graphical drawing exercise and inaccuracy problem associated with graphical
technique. The broad applicability and ease of implementation of LPT are
shown and verified through the solution of several previous case studies
published in earlier literature includes mass transfer based as well as the non
mass transfer based water using operation and problems with multiple pinch
points. In addition, the LPT procedure is characterized by its simplicity and can
be implemented by hand calculations.
