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.

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

The present invention relates to a process for the continuous production of carbonates having aromatic ester groups by reacting aromatic hydroxy compounds with phosgene in the gas phase in the presence of heterogeneous catalysts.

Process for the continuous production of aryl carbonates

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

Process for preparing triisocyanates

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.
