    Abstract: The present invention relates to a computer-implemented method for monitoring and/or controlling a chemical plant. Specifically, the present invention relates to a computer-implemented method for monitoring and/or controlling a physical-chemical process in a chemical plant comprising: (a) receiving sensor data related to the physical-chemical process, (b) determining at least one physical-chemical parameter by providing the sensor data to a plant model, wherein the plant model comprises a mechanistic model containing at least two equations each representing a part of the physical-chemical process and a data-driven model associated to the mechanistic model, wherein the total number of scalars as output parameters from the data-driven model is lower than the number of equations of the mechanistic model, and (c) outputting the at least one physical-chemical parameter determined by the plant model.

    Abstract: Described herein is a process for preparing polyurethane sheet/laminate with reduced bubbles, including the steps of applying a polyurethane system obtained by mixing an isocyanate component (A) and a polyol composition component (B) to form a base coat layer, where the components (A) and (B) are kept separately in tanks under vacuum before mixing, and the application of the polyurethane system is implemented via knife coating under relative humidity of 65% or below. Further described herein are a polyurethane sheet/laminate prepared by the described process and a synthetic leather made from the polyurethane sheet/laminate.
