The design of extraction columns based on information from lab experiments and appropriate simulation tools allows reduction of time and costs compared to conventional design methods using pilot-plant experiments. For this purpose, the behavior of drops and drop swarms is investigated in lab-scale experiments in order to create mathematical models containing system-specific parameters that have to be fitted to those experiments. These models are implemented in a simulation program that solves drop-population balances in extraction columns. At AVT-Thermal Process Engineering of the RWTH Aachen University this concept was implemented in the program ReDrop. ReDrop can predict the separation performance and flooding point of pulsed sieve tray and structured as well as random- packing extraction columns for standard and technical systems. The program has successfully been extended to columns with rotating internals. [less ▲]

Crude oil is the most important raw material for the chemical industry. Due to the continually rising price of crude oil, alternative carbon sources are becoming increasingly important. Biomass is basically the only available renewable carbon source. Because the chemical composition of biomass differs from fossil raw materials, the raw-material change also offers many chances for new product properties and applications. At the same time, the chemical processes have to be redesigned if the feedstock changes to biomass. Here, the effects of a raw-material change are examined on a rather generic level. The study is based on exergy balances and indicates that it is exergetically advisable to reconsider the previously established system of platform and basic chemicals. In general, exergy losses can be minimized if the synthesis pathways leading to the final products are adapted to the chemical structure of biomass. [less ▲]
