Controlled duty
Define circuit, flow, chemistry, temperature, time, valve states and drain for balance, regeneration, heater, hold, divert, cooler and bypass sections under worst deposited soil. The review must also reconcile worst product soil and dirty-hold condition with circuit geometry and parallel-flow paths across normal, transition and fault conditions.
- Worst product soil and dirty-hold condition
- Circuit geometry and parallel-flow paths
- Required result and acceptable operating range
