An experimental study of a novel integrated heat pipe-heat sink for chip cooling

Application of Heat Integration of the Regular Column Sequence in Chemical Production;

The methods of heat integration and synthesis were studied for mixtures with wide boiling-range in terms of its separation characteristics.

Taking trimethylbenzene precise distillation for example,a new heat integration technology for energy saving was put forward.

91% through heat-integration of conventional extractive distillation process.

In the new process with double-effect distillation,the reboiler duties of both pre-column and low-pressure column were provided by the vapor distillate of the high-pressure column,which achieved complete heat-integration of heating steam to reduce the total heat consumption of the whole distillation process.

In the new process with double-effect distillation to realize heat-integration, the feed to the lower-pressure column was a side-stream with moderate methanol concentration drawn from a stage of the higher-pressure column above its feed stage.

Through improving the heat-integrated strategies among the distillation without giving up existing equipment and basic technology, a thermal coupling process is proposed for 1-3-butadiene solvent recovery in a synthetic rubber plant.
