12 | Motonui retrofit a big success The essence of the project was the intricate redesign of 88 distillation trays and the subsequent installation of the new trays inside the plant’s two 70m-high distillation columns. T T from page 10 Methanex REGIONAL DEVELOPMENT “Koch-Glitsch’s team of engineers used sophisticated software modelling to re-design each tray, optimising the flow of liquid to improve the hydraulic performance and contact efficiency of the tray. “Each of the 88 new distillation trays was assembled inside the plant’s 70m columns. The safest way to access these columns was via an industrial lift or staircase.” As with any major project, Methanex’s project was not without its challenges, and Stuart says installation of the new trays was akin to building a ship in a bottle. “After the old trays had been dismantled and removed, each of the new trays were assembled from 320,000 components (120 tonnes).’ “The column was divided into compartments, accessed via purpose-built lifts within a 102-tonne scaffold tower and allowing 50cm of space to work between each tray. Three, 10-person teams worked in parallel, dismantling and then installing new trays in their segment of the column. “The margin for error in such a precise project was extremely thin. During installation, the 6.4mm-wide trays had an allowance of less than 2mm of level. Extensive training of the team, combined with rigorous quality checks and sign-offs meant each of the trays was installed successfully. Your Business, Your Industry, Your News.
