Abstract
This paper presents the results of a study to reduce the energy consumption in a section of a dimethyl terephthalate plant. A thermal analysis was performed to evaluate the opportunities in energy saving. It was found that the plant operates with a high level of energy integration, that is, the maximum amount of heat is recovered by the generation of steam that is utilized in other sections of the plant. Nevertheless, the process design is such that an important part of the heating potential of this steam is lost due to the expansion it is subjected to adjust its pressure to the distribution header pressure which in this way limits its optimum usage. A proposal is also presented to reduce the losses of potential and the overall consumption of energy in approximately 5 millions of Btu/hr.
