Patent ID: 8554381

Claim:
Computer-implemented method for monitoring analyzing and simulating energy consumption of a chemical plant in operation, the method comprising determining a plant-type specific theoretical energy consumption optimum value (TEO) that are used for monitoring current data and/or a predictive model based on fundamental natural laws for planning future energy consumptions by using projections, based on a comparative corresponding model plant, identifying and grouping parameters of dynamic and static processes, contributing to increased energy consumption of the plant by assigning the parameters to a list comprising at least chemical process, infrastructure, plant characteristics, partial load, downtime, product mix, plant operational parameters and losses, providing energy contribution rates for each parameter identified by the grouping, partly by an automatic and/or periodic retrieval, further providing by means of an implemented algorithm a transformation of measured and grouped, static and dynamic data into efficiency data, and periodically graphing the energy consumption of the plant via a grouped bar graph starting from the plant type specific theoretical energy consumption optimum value and arriving at a current energy consumption value (CEC) of the plant by adding the provided single energy consumption rates of the respective static and dynamic parameters in groups, thus forming an energy cascade which allows to monitor and/or to predict at least a part of the individual parameters and to compare the current energy consumption of the plant with an energy consumption of another plant and/or with a previous energy consumption of the plant with respect to the parameters of the list.
