Optimization in the use of energy in a petrochemical process; Optimizacion del uso de la energia en un proceso petroquimico

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.

Se realizo un analisis termico para evaluar las oportunidades de ahorro de energia. Se encontro que la planta opera con un alto nivel de integracion energetica, es decir, se recupera la maxima cantidad de calor en forma de vapor y se reutiliza en otras secciones de la planta. Sin embargo, el diseno del proceso es tal que una fraccion importante del potencial de calentamiento de este vapor se pierde debido a la expansion a que es sometido para ajustar su presion a la del cabezal de distribucion, limitando de esta manera su uso optimo. Se presenta una propuesta para reducir las perdidas de potencial y reducir el consumo global de energia en aproximadamente 5 millones de Btu/hr.}
