Abstract
Component gas is separated from a gas mixture. Component gas flow rate, or demand, is determined. One or more gas separator operating parameters is changed based on the component gas flow rate. For example, gas flow rate can be approximated by measuring a rate of pressure decay of a product tank during a time period in which the tank is not being replenished by the separating system. When it is determined that the flow rate is relatively low, operating parameters of the separating system are changed to improve system performance with the lower demand. For example, a target product tank pressure at which sieve beds are switched can be lowered when demand is lower.
