cost optimization of heat systems 

The reduction of fuel and energy consumption in industry is connected with the utilization of various technological developments and implementations of state of the art energy saving technologies, aimed at the creation of high-performance energy-eco-friendly manufacturing complexes.

During the fuel and energy crisis of the 1970s, energy saving technology for heat exchange systems analysis and designing was pioneered for industrial enterprises. This technique is known as Process Integration (Pinch) analysis and is related to the systematic integration of methods and unit operations of processing. Pinch analysis is based on the first two laws of thermodynamics and it first sets targets for optimal design, before asign mathematical models and techniques to formulate the optimal design to match the targets.

The application of Pinch analysis for the design and retrofit of industrial processes heat exchanger networks allows the designer to identify the values of the energy capacity, consumed from the external and internal units of operation and energy supply at the minimal level of thermodynamic specified demand. The use of Pinch analysis allows you to define: 

• Optimal values for hot and cold utilities;
• The minimal number of heat exchangers in the required heat exchanger network;
• The optimal value of the heat transfer surface area;
• Cost of inputs

Prior to the implementation of any heat exchange network project, the application of Pinch analysis technology enables you to optimize the energy consumption of the territorial production site complex, which consists of multiples of operating processes, and to optimize the energy consumption from the general utility system for the site.

On average, such projects enable you to reduce energy consumption by 30% along with pollution emissions reduction of 20 - 30%. The pay back period of these projects, as a rule, does not exceed one year term.
