Single pulleys may be fixed or moveable. Compound pulleys consist of two or more pulleys.

A chemical engineer needs to design a distillation column for the separation of a mixture containing ethanol (boiling point of 78.4°C) and water. The desired composition of the distillate is a minimum of 90% ethanol. What is the minimum number of theoretical trays needed in the column to achieve this composition, given that the feed contains 40% ethanol and the reflux ratio is 1.5?

Design a chemical reactor system for the production of 500 kg/hr of methanol (CH3OH) through the reaction of carbon monoxide (CO) and hydrogen gas (H2). The reactor should operate at a pressure of 100 atm and a temperature of 300°C, and must achieve a minimum conversion rate of 80%. Determine the type of reactor needed and its dimensions, as well as the required flow rates of CO and H2 gas to meet the production target.

A chemistry student needs to determine the conditions required for a liquid mixture of water and ethanol to boil at a temperature of exactly 80°C. What is the minimum percentage of ethanol needed in the mixture and at what pressure should it be boiled in order to achieve this specific boiling point?

Design a distillation column to separate a mixture of cyclohexane and toluene with a feed composition of 60 mol% cyclohexane and 40 mol% toluene. The distillate product should contain a minimum of 90 mol% cyclohexane and the bottom product should contain a maximum of 10 mol% cyclohexane. You have access to a temperature range of 80-150°C and a pressure range of 1-5 atm. Determine the number of theoretical plates required for this separation and the corresponding reflux ratio.
