Investigate the use of a gasketed plate heat exchanger for the duty set out in Example 12.1: cooling methanol using brackish water as the coolant. Titanium plates are to be specified, to resist corrosion by the saline water.

Data from example 12.1

Design an exchanger to sub-cool condensate from a methanol condenser from 95°C to 40°C. The flow-rate of methanol is 100,000kg/h. Brackish water will be used as the coolant, with a temperature rise from 25° to 40°C.
