Contaminants in plant samples are the most frequent cause of problems with on-line analyzers. Trace contaminants can rapidly build up and cause instrument failure. It’s critical that a filter specifically designed for sampling applications be used rather than a general purpose filter. Read guidelines to ensure proper filtration and sample delivery to on-line analyzers in this white paper.09/23/2013

Chemical plants vary widely in size and complexity yet share common goals for maximizing efficiency safely and cost effectively. This Chemical Processing Special Report tackles two areas in chemical processing - compressed air systems and powder handling - where gains can be achieved for improving efficiency. We also address the concerns of safety as it relates to drying compressed air in hazardous atmospheres.
- Whether compressed air systems are centrifugal, rotary screw, reciprocating compressors or a combination, this Special Report provides and understanding of what’s involved in getting a suitable supply of compressed air.
- Efficient powder handling can be achieved through optimized humidity management.
- Safe drying practices in hazardous air locations
Hazardous locations have or could potentially have high concentrations of flammable gases, vapors, combustible dusts, etc. A small spark can lead to a horrific explosion dangerous to equipment and workers in the area. Equipment located in hazardous areas must be specifically designed to prevent ignition and explosion.
Read this White Paper to learn:
- Types of hazardous areas
- Conditions classified as hazardous
- Hazardous substances
- Specifications for equipment located in hazardous areas
- Explosion proof dryers designed for compressed air systems
Increasingly precise process control strategies, often linked to computer control, have accelerated the use of sophisticated on-line chemical composition analyzers in plant applications. Instruments such as gas and liquid chromatographs, ion chromatographs, laser optic instruments, atomic absorption instruments and specific ion analyzers, which were rarities in laboratories ten years ago, are now found routinely in plant settings.
While continuing miniaturization and “rugged-ization” of the electronics are making the instrumentation circuitry more tolerant of the plant environment, the level of contamination in plant samples compared to laboratory samples continues to plague the process. This white paper reviews the factors in plant operation that may affect the deliverability of acceptable samples and provides guidelines for addressing these factors.11/04/2014
Heat transfer and other process fluids -- from mineral oils to synthetic and organic-based formulas -- are the lifeblood of many critical operations within chemical and the process industries. Their condition reveals critical details about the health of the entire process itself, and that of the components of the system and their interoperation.

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.05/26/2006
OSHAs Hazard Communication Standard (HCS) is based on a simple conceptthat employees have both a need and a right to know the hazards and identities of the chemicals they are exposed to when working.08/30/2005
Under the provisions of the Hazard Communication Standard, employers are responsible for informing employees of the hazards and the identities of workplace chemicals to which they are exposed.03/28/2006

Heat exchanger efficiency is a critical factor in processing productivity, and tube bundles must be kept clear of deposits to maintain that efficiency. Automated high-pressure water jetting systems, with flexible or rigid lances, remove deposits 75% to 90% faster than manual methods and are more operator-friendly.12/14/2009
Automated water jetting removes hardened deposits from tanks and reactors quickly and thoroughly, saving hours of downtime and getting tanks back into service sooner. A new white paper explains high-pressure water jetting, introduces typical equipment, and compares the process with other methods.04/15/2013
High-pressure water jetting is powerful and versatile, helping contractors and industrial companies do hundreds of challenging jobs.
While many jobs are still done manually, new semi-automated systems can maximize three elements crucial to any company’s success: productivity, safety and environmental responsibility.05/12/2015
