A stream of pure cyclopentane vapor flowing at a rate of 1550 L/s at 150 ºC and 1 atm of pressure enters a cooler, which is operating at 1 atm. The cooler functions as a flash separator (one liquid outlet stream, one vapor outlet stream) with 75% of the feed being condensed and exiting the cooler at 1 atm. The liquid stream exiting the cooler is in equilibrium with the exiting vapor. Use a molar flow and enthalpy summary table to help organize your work.
- What is the temperature (ºC) of the streams exiting the cooler? Clearly explain your reasoning.
- Calculate the required cooling rate in units of kW

A stream of water vapor flowing at a rate of 452 mol/h is
brought from 700.0 °C and 10 bar to 400.0 °C and 1 atm. Using Steam
Tables, Estimate the required cooling rate (in kW). Use five
significant figures in your calculations.

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.

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.
