5. A compressor receives CO2 with a pressure of 1 ATM and a temperature of 300 K. The compressor increases the enthalpy of the gas 1.5 times and decreases its volume 6 times. It is also known that during compression there is a heat loss of 32 J/kg. a. What is the work done by the equipment to compress 1 ton of gas? b. What is the final pressure of the gas? c. If the compressed gas is cooled to its initial temperature, what will its new pressure be?
PROBLEM 2 In general, the disposal of hot streams to the environment is not a good a practice due to the risk of violating EPA regulations and also, it represents as waste of potential useful energy. For example, raising the temperature of lakes, rivers, and atmosphere have negative consequences on the ecosystems. In this problem, a gas stream at 500°C contains eight percent mole carbon monoxide and the balance carbon dioxide. Before disposing this gas mixture stream into the atmosphere, it makes sense to recover some of its energy first. To achieve this we will use a heat exchanger where the gas stream flows across the tubes. Water flows inside the tubes entering at 25°C and it is fed at a ratio of 0.2 mole water per mole of the hot gas. The water is heating to its boiling point forming saturated steam at five bar. The steam produced can be used for heating or power generation in the facilities or as the feed for another unit operation. You can assume that heat exchanger is thermally…
