摘要： The present disclosure relates, according to some embodiments, to apparatus, systems, and/or methods for fractionating a feed mixture comprising, for example, one or more isocyanates, light components, solvents and/or heavier components. In some embodiments, fractionating an isocyanate feed mixture may comprise distilling the feed mixture in a non-adiabatic fractionating apparatus comprising a prefractionating section and/or column and a main section and/or column, which comprises a rectification section, a side section, and a stripping section. For example, isocyanates may be separated from light component(s), solvent(s) and/or heavier component(s). A fractionating apparatus may be configured and arranged, in some embodiments, as a dividing wall column. According to some embodiments of the disclosure, apparatus, systems, and/or methods may be energy efficient and/or may have a broad operating range.

摘要： This disclosure relates to a static phosgene mixer, and more generally, to an apparatus for mixing of fluid components such as phosgene and amine during an highly reactive, chemical reaction that is vulnerable to the creation of undesired by-products, and equipment fouling. A guide element ( 5 ) is disposed in the static mixer ( 1 ) to divert the incoming flow of phosgene around the guide element and create an annular mixing passage in the static mixer. This allows for the use of an increased external radius of the effective phosgene flow while maintaining phosgene velocity by creating a blockage of the flow. The same flow, when transformed from a circular configuration to an annular configuration has an increased external radius, and a greater quantity of MDA jets can be placed along the increased radius, thus increasing the overall homogeneity of the mixture. Further, the cross - sectional area of the annular passage section of phosgene defined around the guide element controls the velocity of phosgene which facilitates the mixing of MDA injected through the jets into the phosgene.
