Decades of experience in design and construction, combined with continuous developments in separation technology, enable us to offer you optimum internals. Tailor-made gas and liquid distribution, transition sections, inlet and flashing devices guarantee optimum column performance.
Liquid distribution is crucial for packed bed performance. We offer a wide range of liquid distributors for different applications. Specific distributors are available for:
Liquid loads of 0.02 m3/m2h up to 400 m3/m2h
High turndown rates
Distributors for high loaded columns requiring optimized separation of liquid and vapor and low pressure drop
Distributors for suspensions, emulsions, fouling or contaminated liquids
The distribution of vapor is less critical than that of liquid, but is nevertheless challenging for the design of good vapor distributers. Our experienced engineers rely on decades of expertise implemented in internal design tools, and are supported by cutting-edge technologies such as Computational Fluid Dynamics (CFD).
Liquid collectors with integrated packing support help to save column height. Optimized design of the collecting troughs reduces pressure head in the collecting section. Chimney trays are provided to accumulate liquid and redistribute it, or to improve vapor distribution below packed beds.
Flashing feed has to be separated in or outside the column before liquid and vapor are distributed individually. Different feed conditions are carefully considered in the design of the flash devices.
Sand jetting system consists of a distributor pipe system with multiple jet nozzles and a sand pan at the center. While solids accumulate in the bottom of the vessels, the sand jetting system will fluidize the solids and remove them from the vessel. The sand jetting technology from Sulzer completes the portfolio for separators.
Product applications
Sand jetting systems are widely used in the upstream industry. The most particularly suitable used conditions are:
Support systems are available for every different packing type. They can be easily installed with a minimum of beams and welding attachments. Beside welded constructions, clickable solutions that save installation time are also available. Locating devices can be partly integrated into the liquid distributors to save height and installation time.
