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. Download and read this 22-page white paper to learn more about recovering precious metals from spent catalysts.
Precious metals are often present in hydrocarbon, petrochemical, and chemical catalysts. Techniques for recovering precious metals have been around for many years; yet many catalyst owners have misconceptions about how their refining organizations work. In "The Five Myths of Refining Precious Metals", critical information is shared about the chemical processing industry:
Crucial aspects of weighing
Sampling and analysis of catalysts
Methods of catalyst recovery
What to look for in a proposal from a precious metals refiner
Understanding the cost of quality
How to ensure maximum precious metals return value
Environmental, ethical, and regulatory compliance issues
Over the past 10 years, manufacturers have faced an increasing number of compliance and product quality challenges, ranging from new regulations to product recalls. This White Paper details the business case for an integrated and comprehensive view of product and REACH compliance processes. If "done right," it is expected that these improvements to the compliance process can not only provide time and cost savings but also open doors to new markets, lower risks associated with complex supply chains, protect the reputation of the brand, and create a foundation for environmental sustainability.
Many companies have invested heavily in mission-critical business software initiatives. Much time and effort has gone into deploying sophisticated customer relationship management solutions, adaptive supply chain software, ambitious data migration projects, and other endeavors. All too often, however, these worthy but expensive initiatives fail to deliver anticipated benefits because theyre hobbled by poor data.

Specifying a hygienic bulk solids feeder is not a simple task. The wide variety of requirements needed
for specific applications are similar in scope to explosion proof environmental requirement variations.
Download the white paper to receive information on maximizing the performance of your gravimetric feeder. You will receive tips on how to choose and set up the right feeder for the specific material being fed in your process. Handling free flowing, adhesive, cohesive, aeratable, hygroscopic and pressure sensitive materials plus ways on where and how to properly install a gravimetric feeder are discussed.
The pressure of international competition is being felt in the field of plant engineering with a demand for shorter development times and reduced project costs. A consistent and efficient approach to plant design can help to dramatically save both time and money. Download this white paper to learn more.
Medium voltage VFDs are high cost, high consideration assets that greatly improve process control and efficiency in manufacturing facilities. It is vital that you and your company understand the TCO of this asset. Download the white paper for more information.
The design of the expansion tank plays an important role in the successful operation of a heat transfer system using organic fluids. It can contribute to longer fluid life and lower maintenance. This paper describes the proper sizing, piping and valving, instrumenting, and inerting of the tank.
The high prices for oil and gas have spotlighted other sources of fuel for internal combustion engines. Biofuel, a fuel derived from ethanol, and biodiesel fuel, a dieselequivalent derived from biological sources, are 2 possible substitutes for petrochemical fuel. Palm oil is increasingly used as feedstock for the production of biodiesel, but certain palm oil fractions have other uses, e.g., in the cosmetics and food industries. Sulzer Chemtechs technology supports the separation of crude palm oil (CPO) in its valuable constituents.
Plants have traditionally used trays in the distillation columns to produce fuels grade ethanol. Trays of various configurations have been adequate in this service and their technology is well founded. The ever-present desire to reduce the energy needed to produce a gallon of ethanol has opened the doors to structured packings being used in the rectification sections of ethanol distillation columns.
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.
Except for a few odd services, high liquid rate applications are typically the domain of either trays or random packings. Aside from the distributors, random packing designs are rather straightforward with the designer choosing the proper size to accommodate the fluid flow rates and achieve the desired efficiency. Trays, on the other hand, have a large variety of adjustable parameters and can be especially complex, especially when designed for high liquid rate applications.
