This unit operation simulates transport of bulk solids using a pneumatic conveyor.
● Solids Transport by Pneumatic Conveyor Procedure
If Design Mode, the pipe cross sectional area (and consequently the pipe diameter) is calculated by dividing the operating throughput (MT/h) by the specific throughput (MT/h-m2). If the calculated pipe diameter exceeds the maximum, the program assumes multiple, identical units operating in parallel with a total cross sectional area equal to the calculated. In Rating Mode, the user specifies the number of units and their pipe diameter and the program calculates the specific throughput. The user always specifies the pipe length and the program always calculates the operating throughput.
To account for electricity consumption, the user can either specify the power demand (in kW) or the specific power requirement (in kW/(MT-h)-m). In the second case, the specific power requirement times the operating throughput times the pipe length yields the power consumption.
