Saturated steam at 300°C is used to heat a counter-current flowing stream of methanol vapor from...

Saturated steam at 300°C is used to heat a counter-current flowing stream of methanol vapor from 65°C to 240°C in an adiabatic (no heat exchange with surroundings) heat exchanger. The flow rate of methanol is 400 kg/minute, and the steam condenses and leaves the heat exchanger as liquid water at 90°C. Calculate the required rate of heat transfer from the water to the methanol in kW. Then, calculate the required flow rate of entering steam in m3/min.

Q 5. Saturated steam at 295˚C is used to heat a counter-currently flowing stream of acetone vapour from 65˚C to 290˚C in an adiabatic heat exchanger. The inlet flow rate of the acetone is 7500 standard litters per minute (at 1 bar), and the steam condenses and leaves the heat exchanger as liquid water at 86˚C. I. Calculate the rate of heat transfer from the water to the acetone (kW). II. Calculate the required flow rate of the entering steam...

A heat exchanger is used to transfer heat from a steam stream to a chlorine gas stream. 100 kg of steam at 1 bar and 250°C enters the heat exchanger and leaves the exchanger as saturated steam at 1 bar. Chlorine gas enters the exchanger at 1 bar and 33.0°C and leaves the exchanger at 132.0°C. Assume the heat exchanger is adiabatic. A)What is the specific enthalpy of the inlet steam stream? (Use liquid water at 0.01°C as a reference...

Saturated steam at a gauge pressure of 0.50 bar is to be used to heat a stream of ethane. The ethane enters a heat exchanger at 16°C and 1.5 bar gauge pressure at a rate of 795 m3/min and is heated at constant pressure to 93°C. The steam condenses and leaves the exchanger as a liquid at 20.0°C. The specific enthalpy of ethane at the given pressure is 941 kJ/kg at 16°C and 1073 kJ/kg at 93°C. You may take...

Saturdated water vapor (steam) is commonly used as a heat source in heat exchanger applications. Why saturated vapor? Why saturated water vapor? In a plant of any reasonable size, several varieties of saturated steam are commonly available; for example, saturated steam at 4.5,9,17, and 33 bar. But the higher the pressure the lower the useful energy content (why?), and the greater the unit cost. Why then is higher-pressure steam used?

In the process of methanol production, a gas stream flowing at a molar flow rate of 100 mol / min containing 32 mol% CO, 64 mol% Hz. and 4 mol% of N2 is led to the reactor. The product from the reactor is condensed where liquid methanol is separated. Unreacted gases are recycled in a ratio of 5: 1 mol of recycle to moles of fresh feed. Parts of the recycled gases are purged. The reaction equation is CO +...
