Claim Text:
1. A method for chemical manufacture, comprising: receiving one or more local constraints from a downstream optimization controller of at least one of a plurality of downstream processes via a maximum feed calculator; executing, via the maximum feed calculator, one or more steady state models for the plurality of downstream processes to determine maximum feed capacities of the plurality of downstream processes in a chemical plant subject to the one or more local constraints on the downstream processes, wherein the plurality of downstream processes comprise separation and purification processes, and wherein the maximum feed capacities are determined by the one or more steady state models based on operating conditions of a plurality of individual units within the plurality of downstream processes; inputting the determined maximum feed capacities from the maximum feed calculator into a feed coordinator; executing, via the feed coordinator, one or more steady state models for a plurality of upstream processes to determine upstream production parameters for the plurality of upstream processes in accordance with the determined maximum feed capacities and a specified objective function, subject to one or more global constraints, wherein the plurality of upstream processes comprise a plurality of reactors, and wherein the upstream production parameters are determined by the one or more steady state models based on operating conditions of a plurality of individual units within the plurality of upstream processes; and controlling the plurality of upstream processes in the chemical plant in accordance with the determined upstream production parameters, thereby facilitating maximum production by the chemical plant in accordance with the specified objective function.
