24 in. Baffle space Passes Passes 12 split flow h combined PROBLEMS For the following process conditions determine the size and arrangement of exchanger to fulfill the conditions allowing pressure drops of 10 psi each stream and a dirt factor of 0.004. Employ 1-2 exchangers wherever possible. 11.1. 60,000 lb/hr of 42API kerosene is cooled from 400 to 225F by heating 35API distillate from 100 to 200F. Use 34 in. OD, 16 BWG tubes, 16'0" long on 1546-in. triangular pitch. 11.2. 120,000 lb/hr of aniline is cooled from 275 to 200F by heating 100,000 lb/hr of benzene from 100 to 200F. Use 34 in. OD, 14 BWG tubes, 16'0" long on 1-in. square pitch. 11.3. 84,000 lb/hr of 42API kerosene is cooled from 300 to 100F using water from 85 to 120F. Calculate the requirement using the 1-2 exchangers in series. Use 34 in. OD, 16 BWG tubes, 16'0'' long on l-in. triangular pitch. 11.4. 22,000 lb/hr of 35API distillate is heated from 200 to 300F by 28API gas oil from an inlet temperature of 500E. Use 1 in. OD, 14 BWG tubes, 12'0' long on 1/4-in. triangular pitch. 11.6. 68,000 lb/hr of 56API gasoline is cooled from 200 to 100F using water at 85F. Use 1 in. OD, 14 BWG tubes, 12'0' long on 1!4-in. square pitch. 114 11.6. 32,000 lb/hr of oxygen at 5 psig is cooled from 300 to 150F using water at 85F. (Allowable pressure drop for oxygen 2.0 psi.) Use 34 in. OD, 16 BWG tubes, 12'0' long on 1-in. square pitch. is heated
