A waste stream from our process has 5 g diethylamine/kg water, flowing at 60 kg/min. Presently, cleanup is conducted in an extractor that transfers 80% of the diethylamine (abbreviate as DEA or D) into a stream of chloroform flowing at 60 kg/min. Both streams are available only at these flowrates. Your manager is considering adding a second extractor to improve performance, and she asks you to predict the increased recovery into chloroform (removal from the aqueous stream) that could be obtained. a) Using the performance of the existing extractor, determine the equilibrium distribution factor for diethylamine between chloroform and water. (Show the units on all quantities used.) b) Calculate the overall % removal of DEA expected if you split the chloroform into two equal streams and operate two extractors in a crosscurrent flow configuration.
