  • Measurement of Oxygen Concentration in Blanketing and Inerting Operations

    Gaseous oxygen measurement with amperometric sensors is the most direct and easiest solution for oxidation and explosion protection.

    Unwelcome oxygen Tank blanketing is the process of filling the headspace in storage vessels and reactors with an inert gas to prevent its contents from exploding, degrading or polymerizing and to protect equipment from corrosion. A blanketing system is normally designed such that it operates under higher than atmospheric pressures, therefore preventing outside air from entering the vessel. As oxygen and moisture in the air can be undesired in numerous processes and applications, blanketing is done in a wide range of industries, varying from (petro)chemical to food and beverage, pharmaceutical to pure water.

  • Choosing the Right Emissions Control Option

    Determining the most economical option to control airborne emissions during chemical process operations presents several unique challenges. As with any add-on control system, the goal is to minimize the annualized total costs while maintaining proper operation. In this white paper, learn the different options that are available and which ones fit your process the best.

  • Spray Gas Quench Design Considerations

    The use of spray nozzles to rapidly cool or quench gas streams is an essential application in many industrial processes, such as chemical reaction vessels, incineration, and power plant absorber gas inlet. An optimized spray quench design requires engineering analysis of the operating environment, spray nozzle performance and process reliability. This technical paper describes the design considerations for spray gas quench systems such as nozzle selection, process control, system configuration and reliability. Application of this knowledge can result in a gas quench system that operates efficiently and reliably with reduced vessel size, reduced atomization energy consumption, and minimized downtime, to achieve capital and operational cost savings for your process.

  • Closed System Technology Drives the Trend Toward Safer, More Cost-Efficient Chemical Dispensing

    In dozens of industries and in millions of applications around the world, dangerous chemicals are transferred from their original shipping containers into smaller jugs or buckets or applied to other end-use processes. Historically, the predominant dispensing method in many of these applications has been through an open system where the liquid is poured out of the container. With a poured system, the container is often flipped on its side and the liquid is poured into a secondary container. The user then just carries the bucket to wherever it needs to go. A mental image of this technique quickly reveals its potential dangers and inefficiencies.

  • 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.

  • Environmental Health and Safety Compliance in Biotech Companies: Common Deficiencies Encountered During Audits

    Environmental health and safety (EH&S) compliance programs for companies that house laboratories are complex and not easily maintained. Even the most basic plan involves keeping a variety of permits up-to-date, performing regular employee training, conducting inspections, complying with a myriad of chemical storage and handling requirements, and keeping a number of contingency plans current and complete. This white paper identifies the most common pitfalls and four simple steps to keeping your EH&S program current.

  • Guidance note for environmental safety instrumented systems

    Safety Instrumented Systems (SIS) are designed to monitor the process and control outputs to prevent or mitigate hazardous events. The design process strives for inherent safety, which is enhanced by applying multiple independent safety layers. Learn how to prevent accidents with prevention layers and minimise the consequences with mitigation layers.
