Method and system for monitoring and analyzing energy consumption in operated chemical plants

Abstract

The invention relates to a method and system for monitoring and analyzing energy consumption in operated chemical plants. The present disclosure refers to a computer-implemented method for monitoring and analyzing energy consumption of at least one operated chemical plant, the method comprising determining a plant type specific theoretical energy consumption optimum value based on a corresponding modeled plant, identifying and grouping parameters contributing to an increased energy consumption of the plant due to processes running on the plant, due to internal characteristics of the plant, due to operating conditions of the plant, respectively, providing, such as partly automatically retrieving energy contribution rates of the respective parameters, and periodically graphing the energy consumption of the at least one plant via a bar graph starting from the theoretical energy consumption optimum value and getting up as an energy cascade to a current energy consumption of the at least one plant by adding the provided, partly retrieved single energy consumption rates of the respective parameters in groups such that the resulting energy cascade allows to monitor at least a part of the individual parameters and to automatically compare the current energy consumption of the at least one plant with an energy consumption of another plant and / or with a previous energy consumption of the at least one plant with respect to the individual parameters. Furthermore, an appropriate system is provided.

Description

technical field [0001] The present invention relates to a method and system for monitoring and analyzing energy consumption in an operating chemical plant. Background technique [0002] US 4,146,923 describes a system for controlling multiple variable rate consumption units using a unique sequence to optimize the total consumption of said units and the number of activated units relative to a target in a manner that responds to comparing the total cost to a target and increasing and decreasing the total cost from a state position in the sequence in response to the comparison of the total cost to the target minus the difference cost from the state position in the unique sequence to the next step . The status of the unit and the result of the comparison address the device storing the unique sequence to provide the status of the consumption request, which can be overwritten by cyclic means to turn min and max off Time and minimum on-time demand command states are provided to d...

Problems solved by technology

However, said technician does not often have an overview of the complexity of the parameters influencing each other in the operating state of the facility, so that an overall comprehensive improvement management cannot be implemented on it

[0012] The prior art does not provide a solution to define a program according to which the performance of a facility can be characterized formally and abstractly such that deviations from optimal values ​​can be represented so that different facilities can be compared with way of comparing each other
