Energy Flow Analysis and Optimization of Tahe No.1 Union Station

The Tahe No. 1 Union station has undergone many transformations, and the existing energy flow direction is unreasonable. In order to improve the efficiency of energy utilization within the Union Station, the energy flow diagram of Tahe No. 1 Union Station was firstly analyzed, and it was found that there were weak links in heat loss and heat energy consumption at the separator equipment. Afterwards, the existing heat exchange network was analyzed using the problem table method in the pinch technology, and it was found that there were two hot streams that violated the principle of pinch technology, and energy-saving transformation was carried out on them, the energy-saving potential could reach 54.7%. After analysis, it was found that if there is a heat exchange process in the system, it can be pinch technology to find out what is not right in the system and to modify it. The pinch point analysis technique is therefore a highly applicable energy saving technique.

I. Introduction

At present, the analysis of the energy saving potential of energy-consuming equipment is mainly focused on the energy analysis and evaluation of single equipment, while the energy flow relationship between different upstream and downstream equipment and processes is less involved. For example, Ngancha [1] et al. have analyzed the pump as a piece of equipment and achieved energy savings in the equipment through hydrodynamic analysis.
