The allowable pure flow rate setting depends on the column inlet pressure. Figure 3.5.3
shows the range of purge flow rates permitted.
Fig. 3.5.3
Allowable APC settings are shown below, for a supply pressure of 500 kPa. (When the
supply pressure is less than 500 kPa, the available maximum flow rate decreases
proportionally.) When the set value is more than the set range, displayed values may not be
accurate, or APC cannot control the flow.
