Abstract: A computer-implemented method for monitoring and analyzing energy consumption of a chemical plant in operation. Plant type specific theoretical energy consumption optimum value based on a corresponding modeled plant are determined, parameters contributing to increased energy consumption are identified and grouped. Energy consumption of a plant is periodically graphed starting from the theoretical energy consumption optimum value and getting up as an energy cascade to a current energy consumption, 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.

Abstract: A computer-implemented method for monitoring and analyzing energy consumption of at least one industrial building is provided, the method comprising determining a building type specific theoretical energy consumption optimum value (TEO) based on a corresponding modeled building, identifying and grouping parameters contributing to an increased energy consumption of the building due to an actual use of the building (CEC), due to intrinsic characteristics of the building (BEO), due to optimised designated operating conditions in an actual state of the building (OEO), respectively, providing energy contribution rates of the respective parameters, partly by an automatic, and whenever required, periodic retrieval, and periodically graphing the energy consumption of the at least one building via a bar graph starting from the building type specific theoretical energy consumption optimum value and arriving at a current energy consumption of the at least one building by adding the provided single energy consumption rat

Abstract: Triisocyanates are produced by gas phase phosgenation of the corresponding (cyclo)aliphatic triamines having three primary amine groups.

Abstract: Diisocyanates are produced by gas-phase phosgenation of aliphatic diamines having two primary amino groups in the 1,2- or 1,3-position to one another or by cycloaliphatic diamines having two primary amino groups in the 1,2- or 1,3-position to one another.
