It is required to heat 2000 hl/day of 37 °API crude oil in a fired heater from 220 °F to 650 °F using refinery gas. NHV =1700 BTU/lb, as a fuel. In the radiant section, the heat rate is 45000 BTU/hr.ft2 of projected area. The tubes are of (15" outside diameter, 40' long, and 10" spacing) and arranged in two rows. Given: R%-44%, Cp oil -2.3 BTU/lb. °F, pwater =62.4 lb/ft3, 1 ft³-0.02832 m³ .Calculate: 1. The mass flow rate of fuel required. 2. Number of tubes in radiant section.
