  • Three cost effective ways to strengthen trays against uplift

    Several common operating conditions cause tray damage, including high liquid levels, free water flashing at the bottom of the column, and excessive pressure drop. The result can be an expensive shutdown causing lost production and profit. Increasing tray thickness can be a first approach for strengthening the tray, but this can increase the material cost of the trays by 50% or more. Sulzer commonly uses three simple cost effective alternatives to increase tray strength in new ...

  • Tray designs for extreme fouling applications

    Today refiners experience a lot of problems with processing of opportunity or heavy crudes. Such crudes have very high sulfur content and require the addition of amine scavengers before desalting. These amines decompose in the heater and create ammonium chlorides in the presence of water in the top of the crude tower. Dissolved salts start to precipitate and crystallize when the solution becomes saturated and water is vaporized. Such fouling starts to grow below and above trays ...

  • Understanding design and performance of high performance structured packing

    High performance structured packings have been on the market for around 10 years. They continue to gain market share because of their high capacity and excellent efficiency. This is especially true in vacuum tower applications where pressure drop is critical. High performance packings can yield substantial savings in capital and operating costs with increased capacity and lower flash zone pressure and temperature. Packing Design Fundamentals One of the fundamental characteristics ...
