  • Raising Confidence and Driving Business Value with Product and REACH Compliance

    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.

  • Recovering Precious Metals from Spent Chemical Processing Catalysts

    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.

  • Rectifier design for fuel ethanol plants reduces energy

    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.

  • Reducing Water Consumption in Compressed Air Systems

    Compressed air systems are sometimes called the "4th Utility" due to their presence in almost all industrial processes and facilities. As US water consumption continues to increase, compressed air systems provide an opportunity for energy managers to reduce associated cooling water consumption and costs. In this white paper, we focus on the opportunity to reduce the water consumption of compressed air systems. Understanding the costs and the alternative types of cooling systems is an important first step. This white paper provides background on US water consumption in both the public and industrial sectors; it provides detail on industrial water consumption -- including industrial cooling water -- and its associated costs; it also details six different types of cooling systems available.

  • Relief Design for Reactive Systems – Get the Facts

    This 15-page paper focuses on the additional degrees of complexity that reactive systems pose for emergency relief systems. It covers topics such as how to screen for reactivity and what practices, standards and regulations should be followed, as well as a host of other issues.

  • Removing Liquid From Gas

    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.

  • Risk-Based Process Safety Design

    Safe design has long been a priority in the process industries. A safe design basis, together with a formal safety management system and safety practices, procedures, and training, is critical for providing that level of confidence required for risk management. The goal of process safety management is to consistently reduce risk to a level that can be tolerated by all concerned. A systematic, risk-based approach to safety design can help eliminate hazards that pose intolerable risk from the process and mitigate the potential consequences of hazards.

  • Save Money, Time, and Water With Rotary Impingement Tank Cleaning

    Tank cleaning has always been viewed as a necessary evil for manufacturers. During the cleaning process, a significant amount of resources (time, chemicals, water, electric and labor) is required between batches to ensure a reliable, uncontaminated, quality batch is produced. Although these repeating expenditures have a significant effect on the bottom line, many chemical manufacturers continue to rely on outdated processing for cleaning, not realizing the potential opportunity for substantial cost reductions and revenue recovery through CIP optimization.This whitepaper includes specific case studies on the benefits of rotary impingement and CIP optimization vs. the standard tank cleaning processes. These benefits include drastic savings in time and water usage as well as employee safety.
