Development of multistage distillation in a microfluidic chip
Microfluidic separations is an important area in microprocess engineering. Distillation, even though it is an important chemical engineering operation, has had only limited success in the microscale. This paper shows a new approach in microfluidic distillation, utilising heat pipe principles for fluid movement. Microdistillation can have a significant impact in the analysis of small volume or high value components and in the design of microchemical plants. The paper presents the systematic approach we used to solve the various problems encountered. It is one of only a couple of papers internationally that has demonstrated multistage distillation at an extremely small scale.
