Abstract


Distillation is the most widely used separation technique , have a significant impact on the energy consumption of households in the process industry , the production capacity of the entire process , product quality , energy consumption and raw material consumption , environmental protection . The conventional distillation column distillation sequences were not suited to the current process integration , device integration trends . Break through the traditional the simple the Tata structures , design energy-efficient multi-component complex distillation equipment and processes is a very important and challenging topic . Complex fractionator use with conventional fractionator one feed , two stocks fractionator comparison , it is possible to produce relatively large energy consumption and costs savings . Complex tower for updated design , because it often implement minor changes to the existing tower . In the the possible multicomponent distillation process new program , the thermally coupled distillation energy savings and investment costs are very promising . In this paper , the use of the the Underwood equation and the of V min < / sub > minimum energy consumption analysis of multi-component thermally coupled distillation ; mainly discussed with a detailed model of the tower to the multi-component heat even distillation column design , the tower model is able to describe the traditional tower thermally coupled distillation column can be described and compared with each other allows different options structure ; minimal energy consumption target , multi-component mixture separation thermally coupled distillation the sequence of the overall optimization methods . Finally, the separation of the four-component hydrocarbon mixture , for example , according to the detailed thermocouple the distillation column mathematical model to calculate the energy consumption of thermally coupled distillation , the annual total cost , and compare the energy-saving effect of various thermocouple programs . Energy consumption minimum , the overall optimization of the two thermally coupled distillation sequences .
