  Most chemical processors use precious-metal-bearing catalysts for facilitating and/or speeding chemical reactions. These catalysts are typically composed of platinum group metals (PGMs). After a number of process cycles the catalysts lose their efficacy and must be replaced with fresh catalysts. Spent catalysts are sent to a precious-metals refiner for recovery and refining of the valuable PGMs remaining in this material. Selecting—and working with—a precious-metals refiner is critical to ensure highest possible returns and peace of mind with regard to environmental concerns.

  Liquid entrainment in a gas stream can be a disturbance in many industrial processes. In natural-gas processing, higher-order hydrocarbons, water or impurities have to be separated from the main methane stream. Upstream of gas compressors, droplets that can damage the impellers, have to be removed. With the recently acquired Knitmesh technology and the strategic alliance with Shell Global Solutions, Sulzer Chemtech can supply a broad portfolio of advanced, tailor-made systems for gas/liquid separation to customers in all industries.
