  • Structured grid packing

    Structured grid packings have traditionally been used for high severity services. Grids have a high open area, relatively low surface area, and a robust construction to withstand process upsets and to resist fouling. There are two main types of grids, categorized by structure - conventional grid and corrugated, high-efficiency grid. Developed first, conventional grids have a structure made from vertical members and angled flaps. The simple construct is fouling resistant, but has ...

  • 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 ...

  • Traffic jams in your amine system

    Have you ever found yourself in a traffic jam – one that results in a gridlock? If you have, you probably will not forget the frustration and headache that resulted from lost time just sitting there feeling helpless. You probably felt there were just too many cars on the road. If there weren’t so many, things would run smoothly and be alright. Have you considered the possibility of too much traffic in your amine system? Have you had to increase solvent circulation ...

  • 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 ...

  • ULTRA-FRAC® Technology

    Expand your Capacity Not your Vessel. Before the introduction of ULTRA-FRAC® trays, appreciable capacity increases in light hydrocarbon services could be achieved only through new column construction.  With ULTRA-FRAC, existing columns can be retrofitted, resulting in significant capacity increases without the major capital expenditures and space requirements of building new columns. ULTRA-FRAC is the ultimate tray, outperforming all other trays not only those in the ...

  • Understanding amine system terminology

    As we work with valued customers in our business, we have come to realize that there is confusion with some of the terms used to describe amine systems. Some of these terms such as Heat Stable Salts, Heat Stable Amine Salts, Lean Loading, Bound Amine, etc may need clarification. We explain below the differences with these terms because we recognize it is helpful to understand them.

  • 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 ...
