A 100 kmol/h stream that is 97 mole% carbon tetrachloride (CCl4) and 3% carbon disulfide (CS2) is to be recovered from the bottom of a distillation column. The feed to the column is 16 mole% CS2 and 84% CCl4 , and 2% of the CCl4 entering the column is contained in the overhead stream leaving the top of the column

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
