Notes:

a. Units -- Indicates the number of streams x autoclaves per stream for continuous plants

b. Type -- V = Vertical cylinder, H = Horizontal x number of compartments ( number of agitators), S = Spherical

c. Heat Exchange -- F = Flash generation of steam, F & S = product to feed heat exchange using flashed steam in splash condenser - number of stages indicated, SAT = Shell and Tube, CP = Concentric pipe exchanger.

d. Feed Pump Type -- C = Centrifugal, D = Diaphragm, A = Air, H = Hydraulic

e. -- Aluminum Plants -- Only one plant is shown as an example. There are numerous high pressure Bayer style plants around the world
