Gasoline (65° API gravity) flow rate of 60,000 lb/h with a small boiling range at 400°F is to be vaporized to form 37,050 lb/h vapor at an operating pressure of 200 psig. Use gas oil (30°API gravity)

Gasoline (65° API gravity) flow rate of 60,000 lb/h with a small boiling range at 400°F is to be vaporized to form 37,050 lb/h vapor at an operating pressure of 200 psig. Use gas oil (30°API gravity) in the temperature range from 600 to 500°F at 120 psig operating pressure as the heating medium. A tube side pressure drop of 10 psi is allowable. Design a suitable Kettle reboiler to serve the purpose.
