Dear Team,
We are reviewing Plate type heat exchanger design from some vendor, the exchanger is basically lean/rich amine exchanger for amine plant. we come across that the vendor has used exchanger nozzle of 3-inch for 6-inch inlet pipe size. so far unable to find criteria for this reduce nozzle size. One side fluid parameters are as under.
Flow : 278 usgpm (Hot Lean Amine)
Density : 62.28 lb/ft3(Hot Lean Amine)
viscosity: 0.57 cp (Hot Lean Amine)
Flow : 269 usgpm (Cold Lean Amine)
Density : 60 lb/ft3(Cold Lean Amine)
viscosity: 1.2 cp (Cold Lean Amine)
It would be helpful if any of you can suggest better way out to understand this.
