Hydrogenation system for c3 and c4 acetylenes
The granted patent US12037553B2 outlines a system designed for the hydrogenation of acetylenes within a hydrocarbon stream, which is integral to the operation of an ethylene plant. The system includes several key components: a debutanizer that generates an overhead stream, a condenser that condenses this stream into a liquid phase, and a C4 acetylene hydrogenation reactor that selectively hydrogenates the condensed stream. Following these components, a depropanizer and a methyl acetylene and propadiene (MAPD) reactor are positioned downstream, with a stripper column designed to vent off any residual unreacted hydrogen. The configuration ensures that the hydrogenation process is efficient and maintains the condensed stream in a liquid state throughout the reaction.
Further claims detail the arrangement and functionality of the system components. Notably, the stripper column can be positioned downstream of the MAPD reactor to receive a crude propylene stream, and the C4 acetylene hydrogenation reactor is linked to the depropanizer, which produces a bottoms crude butadiene product stream. The design also specifies that there is no additional stripping column required for venting unreacted hydrogen from the crude butadiene product stream. Additionally, the condenser is equipped with a refrigeration medium, enhancing the system's operational efficiency. This patent presents a comprehensive approach to hydrogenating acetylenes, contributing to advancements in ethylene production processes.
