Multiple-level treatment for optimizing one or more fluid separation units

摘要

The invention relates to the optimized management of one or more fluid production units, especially those involving fluid separation treatment, comprising: a) a data collection step, the data being on one or more values of current parameters defining a current operating point of the production unit, on a future production demand and on at least one optimization criterion; and b) a computation step for computing one or more parameters defining a new operating point of the unit, at least in accordance with this demand. The computation step b) comprises at least: 1) an estimation of at least one optimum solution for defining the new operating point; and 2) a validity test carried out on this optimum solution, at least in accordance with an analysis of the transition of the production unit from the current operating point to the new operating point.

1. A computer-implemented method for optimizing the management of at least one production unit producing at least one fluid by co-production of fluids, the method comprising the steps of:
a) collecting, by operation of at least one computer processor, data, the collected data comprising:
one or more current parameter values defining a current operating point of one of the at least one production unit,a future production demand, andat least one optimization criterion;simplifying the collected data such that a long-term task of the future production demand is defined as a succession of transitions from the current operating point to a new operating point satisfying the future production demand; b) computing, by operation of the computer processor, one or more parameters defining the new operating point of the at least one production unit, at least according to the future production demand, wherein step b) comprises:
b1) an estimation of at least one optimum solution for the definition of the new operating point, andb2) a test of validity of the optimum solution comprising an analysis of each of the succession of transitions of the at least one production unit from the current operating point to the new operating point, wherein the test of validity determines whether each given transition results in a stable operating state for the at least one production unit at that transition; and c) directly electronically transmitting the one or more parameters to at least one automatic system to control at least one of a flow rate, a pressure, a temperature, or an equipment run state of the at least one production unit when the validity of the optimum solution is validated to cause the at least one production unit to reach the new operating point via the succession of transitions of the at least one production unit from the current operating point to the new operating point to produce the at least one fluid.
