Kinergetics' Pseudo-Pinch Design

PsuedoPinch Design [noun]: The combination of certain aspects of advanced evaluation ethadologies such as Pinch and Availability Analysis with practical design.

Benefits: Identification of “hidden” energy efficiency opportunities, assign practical minimum utility targets, and assignment of reasonable cost to energy flows within a facility.

PseudoPinch Design was first applied during an energy investigation at an ethanol plant in

2016

Application of PsuedoPinch Design lead to idetification of a fuel reduction of approximately

17 MMBTU/Hr in a portion of the facility.

While initially applied to ethanol production, PseudoPinch can be applied in any facility, including those with CHP and waste heat to power opportunities.

PsuedoPinch Applications in Paper & Ethanol Plants

The relative value of low pressure steam in a paper mill. The Energy Ratio sets value based on enthalpy, and shows very little changes with temperature.

The Availability Ratio shows the more correct values as the Ratio drops with temperature.

The steam is worthless at 70 degrees Fahrenheit.

Here is a grid diagram of an existing heat recovery network developed during application of Pseudo-Pinch at an ethanol facility

A total fuel use reduction of 32 MMBTU/Hr was identified.
