    • 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.
    • 根据一些实施方案,本公开涉及用于分馏包含例如一种或多种异氰酸酯,轻组分,溶剂和/或较重组分的进料混合物的装置,系统和/或方法。 在一些实施方案中,分馏异氰酸酯进料混合物可以包括在包含预分馏段和/或塔以及主要段和/或柱的非绝热分馏设备中蒸馏进料混合物,所述主要段和/或柱包含精馏段,侧段和 剥离部分。 例如,异氰酸酯可与轻组分,溶剂和/或较重组分分离。 在一些实施方案中,分馏装置可以构造和布置为分隔壁塔。 根据本公开的一些实施例,装置,系统和/或方法可以是高效的和/或可以具有宽泛的操作范围。
