A
Pinch Analysis study assesses the following energy efficiency solutions:
>
 Heat
recovery: heat exchangers, streams mixing, economizers, quenching
towers and other heat transfer means;
> Utilities
optimization: steam pressure levels, boilers efficiency, make-up
water preheating, refrigeration levels...;
> Identification
of judicious process modifications: equipment and operation
(pressures, temperatures, flows,...);
> Best
schemes of integration for heat pumping, thermocompression,
mechanical vapor recompression and cogen units;
> Streams
reuse / recycling;
>
Appropriate integration of existing and
new unit operations (evaporators, dryers, distillation columns,
etc.). |

The savings
identified vary largely and can be as high as 90% (ex.: Kraft mill) of
the fossil fuel bill. Savings around 25% of the fuel bill for payback
periods of 12 to 24 months are typical values. The important points to
remember are:
>
In any plant, the minimum energy
requirement can be calculated with Pinch Analysis;
>
Among the most
cost-effective solutions can be designed to get as close as possible
to this minimum value for a given economic criterion.

Pragmathic
expertise in Pinch Analysis rests on the 16 years of experience of its
personnel in process integration for the sectors of pulp and paper, petrochemical and food and
beverages.
For any plant,
a minimal management commitment to energy efficiency is mandatory to
achieve real results. In plants where this condition is met, the rate of project
implementation of a Pragmathic's Pinch analysis study is always high,
and the savings and profitability obtained are on target.
