Question:
Design a shell and tube exchanger to heat 50,000 kg/hr of liquid ethanol from 20 DegC to 80 DegC.Steam at 1.5 bar is available for heating.
Assign the ethanol to the tube side. The total pressure drop must not exceed 0.7 bar for the ethanol stream.
Plant practice requires the use of carbon steel tubes, 25 mm inside diameter, 29 mm outside diamter, 4m long.
在HTRI设计时,调整换热管长度为12 feet (3658 mm),外径1.25 inch (31.75 mm), 壁厚0.083 inch (2.108 mm)。
检查又调整了下Baffle方向,由垂直方向改为平行方向。Baffle的间距也做了下微调。
