摘要： A process for preparing an isocyanate product includes providing a phosgene inlet stream and an amine in solvent inlet stream to a phosgenation mixer, the amine in-solvent inlet stream including one or more amines and one or more inert solvents, and during steady state operation compensating for a fouling pressure drop increase by decreasing a pressure drop in the phosgenation mixer over a time period divided into at least a first period of time T1 and a second period of time T2 that is subsequent to the first period of time T1. During the second period of time T2 an amine concentration of the one or more amines in the amine-in-solvent stream is higher than during the first period of time T1, and during the second period of time T2 a phosgene-to-amine ratio value in the phosgenation mixer is higher than during the first period of time T1.

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.
摘要翻译：本公开涉及静态光气混合器，更一般地，涉及在容易产生不期望的副产物和设备污染的高反应性化学反应期间混合流体组分如光气和胺的装置。引导元件（5）设置在静态混合器（1）中以将进入的光气流转向引导元件周围，并在静态混合器中产生环形混合通道。这允许使用有效光气流的增加的外部半径，同时通过产生流动阻塞来保持光气速度。当从圆形构造转变为环形构型时，相同的流动具有增加的外部半径，并且可以沿着增加的半径放置更大量的MDA射流，从而增加混合物的总体均匀性。此外，围绕引导元件限定的光气的环形通道部分的横截面面积控制了光气的速度，其有助于通过射流喷射的MDA与光气的混合。

摘要： Excessive residence time in the conduits located between the outlet of a static mixer and a reactor/separator reservoir can lead to undesired by-products, formation of solids, and conduit fouling. This disclosure relates to an improved configuration for a static mixer with reduced transitory time to help reduce the creation of undesired by-products and fouling during the process of mixing, and more particularly to a phosgene reactor comprising a short or very short conduit for reducing the transit time from the static mixer to a reactor/separator reservoir to one second or less.
