3. A mixture of 10 wt% water and 90 wt% chloroform enters a gravity separator at the flow rate of 20 kg/s through a 3 inch schedule 40 steel pipe (this mixture has a density of 1200 kg/m³). The mixture separates into a light phase and a heavy phase. The light phase consists of 99 wt% percent water and the heavy phase consists of 97 wt% chloroform. The density of the light phase is 1100 kg/m³ and the SG of the heavy phase is 1.40. The separator is a vertical cylinder operated at 30°C with the light phase overflow placed 5m from the bottom of the tank. The inside diameter of the tank is 3m. All lines and the tank are vented to the same pressure. Determine the velocity of the feed (m/s). Determine the flow rate of the light and heavy phases (kg/s). If the overflow for the heavy phase is brought to a level 4 meters above the bottom of the tank, at what level (meters) will the interface be from the bottom of the tank? How much time does the light and heavy phase spend in the tank (minutes)? d. e. Estimate the ideal separation time for these two fluids. f. What process adjustments could you make so parts d and e match?

Transcribed Image Text:A mixture of 10 wt% water and 90 wt% chloroform enters a gravity separator at the flow rate of
20 kg/s through a 3 inch schedule 40 steel pipe (this mixture has a density of 1200 kg/m³). The
mixture separates into a light phase and a heavy phase. The light phase consists of 99 wt%
percent water and the heavy phase consists of 97 wt% chloroform. The density of the light
phase is 1100 kg/m³ and the SG of the heavy phase is 1.40. The separator is a vertical cylinder
operated at 30°C with the light phase overflow placed 5m from the bottom of the tank. The
inside diameter of the tank is 3m. All lines and the tank are vented to the same pressure.
Determine the velocity of the feed (m/s).
Determine the flow rate of the light and heavy phases (kg/s).
If the overflow for the heavy phase is brought to a level 4 meters above the bottom of
the tank, at what level (meters) will the interface be from the bottom of the tank?
