Question

A gravity separator is a large, horizontal-shaped tank that can be used to separate two fluids of different densities. A single inlet stream, containing 35wt% chloroform and 65wt% water, and flowing at 1000 kg/h and 4 oC, is separated into two separate outlet streams containing pure chloroform and pure water.

1. What are the densities of chloroform and water (kg/L)? Which fluid separates on top and which fluid separates to the bottom?

2. Determine the mass flow rates for each component in the inlet stream.

a. What are the molar flow rates for each component (kmol/h)? b. What are the mole fractions for each component?

3. Determine the mass flow rates for each outlet stream (kg/h).

4. Determine the volumetric flow rates for each outlet stream (L/h).

Explanation / Answer

1m3 = 1000 litres.

1. density of chloroform= 1.48 g/cm
