Benzoic acid was extracted from water with heptane in a single stage HRDC extractor
College of Chemical Engineering and Chemistry Technology, Southwest Petroleum University, Chengdu 610500, China
The horizontal rotating disc contactor (HRDC) for extraction consisted of a mixing chamber and two settling chambers, which enabled continuous cycling of the dispersion-mass transfer-separation processes and achieved higher mass transfer efficiency compared to a single equilibrium stage. The extraction efficiency of benzoic acid/n-heptane/water system was measured by an HRDC extractor, and the two-phase concentration could be measured by spectrophotometer. The experimental results showed that the extraction efficiency of benzoic acid/n-heptane/water was 46%.
Key words: HRDC extractor / extraction efficiency
