Chemical Engineering Q: Is a laboratory scale distillation column or an industrial scale distillation column more efficient? Give reasons to support your answer.
Homework Answers
Laboratory scale distillation column are more efficient than industrial scale distillation column mainly because of below reasons
1)In industrail distillation columns some of the energy losses may be there due to surrounding atmosphere but in laboratory it is fully isolated
2)Murphee efficiency of small column is high compare to large column ,so obviousley small column has more efficiency compared to large column
3)Condenser and Reboiler loads for small are small and large for large columns
4)The effectiveness of column depends on No.of Transfer units ----> Z = HTU x NTU
5)In industrial scale columns there is a problem of Weeping,dumping . Entrainment problems

4.6. A distillation column is a process unit in which a feed mixture is separated by multiple partial vapor- izations and condensations to form two or more product streams. The overhead product stream is rich in the most volatile components of the feed mixture (the ones that vaporize most readily), and Equipment Encyclopedia distillation column the bottom product stream is rich in the least volatile components. The following flowchart shows a distillation column with two feed streams and three product...

10. The UTC chemical engineering program is looking to purchase a new reboiler (a type of heat ZUVOR exchanger) for the distillation column in EMCS 120. In the design specifications, liquid water enters the heat exchanger at T = 100°C and P = 3 MPa. The total heat transferred to the water, from a resistance heater at T = 1727°C, is 1000 kW. The outlet temperature and pressure of the water is 500°C and 3 MPa. The mass flow rate...

Nitric acid is a key industrial chemical, largely used to make fertilizers and explosives. The first step in its synthesis is the oxidation of ammonia. In this reaction, gaseous ammonia reacts with dioxygen gas to produce nitrogen monoxide gas and water. Suppose a chemical engineer studying a new catalyst for the oxidation of ammonia reaction finds that 988 liters per second of dioxygen are consumed when the reaction is run at 188. "C and 0.56 atm. Calculate the rate at...
