HACH BioTector 3500c Analyzer For TOC, TC, TIC and VOC Analysis
In recent years, TOC analysis has become accepted in the industry as the standard method and the only reliable online method used to determine contamination in waters, to control processes, to prevent product losses and to minimize waste. It is especially important to monitor this parameter in applications such as condensate return water, boiler/feed water, etc. In boiler/feed water and in industrial steam generating systems, carbonic acid corrosion of condensate lines is often a serious problem. Depending on the application type, analysis of only one parameter (e.g., TC) is generally not sufficient to make any useful process decisions. Multiple-parameter analysis (TOC, TC, TIC, VOC etc.), as carried out in the Hach BioTector B3500c analyzer, is proven to be more useful and always superior to single-parameter analysis in the industry.
Loss on Drying vs. Thermogravimetric Analysis
Synthesized is used in a variety of applications. The construction industry uses it as the primary ingredient in drywall, and as a setting inhibitor in Portland cement. The property of Gypsum that makes it valuable as a fire retardant in construction materials is also what makes it a good candidate for Loss on Drying analysis.
Chemical Processing Special Report: How to Succeed with VFDs
Medium voltage variable frequency drives (VFDs) are often the best choice to capitalize on opportunities to significantly reduce the operating and maintenance costs associated with relatively large rotating equipment. Even a seemingly modest energy savings of a few percent of the operating load can translate into significant energy savings. In this special report we take a look at how to make the most of VFDs: how optimum performance depends upon proper installation and control; how controlling the speed of VFDs can help eliminate waste and promote efficiency, reliability and quality and; considerations for changing drive speed over pumps.

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.

Powders developed to meet certain product performance targets often suffer from inconsistent and unpredictable flow. The reasons for this are many. A material's characteristics - adhesiveness, cohesiveness, aeratability, pressure-sensitivity - often change during processing and can cause flow problems to crop up. Couple this with changes in the processes themselves and costly downtime can be the result. In this Chemical Processing Powder eHandbook, we take a look at strategies and solutions for overcoming powder processing challenges including:
Making the most of flow additives - understand their impact on overall powder behavior to optimize flow
Improving performance of gravimetric feeders - tips to avoid poor accuracy and frequent downtime
Protecting against combustible dust explosion - economical approaches for protecting spray dryer processes and solutions

Energy consumption remains one of the largest controllable costs in oil refineries. Heat exchanger fouling can have a significant impact on energy efficiency and production loss. Asphaltene Precipitation is caused when refiners blend incompatible crudes. This is a major source of fouling and leads to performance limitations within days. Heat exchanger fouling is a major challenge for refinery operations. With the increase in crude blending from opportunity crudes such as tight oil, the traditional “manual” monitoring approach may no longer be effective. This White Paper discusses how on-line monitoring and analysis can enable refineries to:

Breakdown of organic wastes entering a wastewater treatment plant is accomplished by using a biomass or blend of beneficial microscopic organisms, bacteria, and solids. This converts the nonsettleable solids (dissolved and colloidal matter) into settleable solids, carbon dioxide, water, and energy. This paper reviews the most common stages for measuring and controlling dissolved oxygen in a wastewater treatment plant.
Operating and maintaining a reliable steam system is vital to chemical processing plants and can have significant cost impact on a plant's annual budget. Typical profit drainers in operating and maintaining a steam system include excessive fuel cost, inefficient steam generation, less-than-optimal steam utlization and poor condensate recovery. Ensuring adequate supply of steam often results in excessive capacity usage, expensive fuel choices or condensate draining to grade, leading to compromised efficiency levels and higher steam cost. Because steam systems dependency is unavoidalbe, addressing those three issues is crucial to minimizing steam costs. This Chemical Processing Steam eHandbook presents an overview, steam technologies and strategies for reducing cost associated with using and generating steam including:

The debate over the virtues of DCS vs. PLC has been ongoing since these two architectures came into existence 40 years ago. For certain industries, a distributed control system (DCS) provides substantially more value as the basis for automating the plant than a programmable logic controller (PLC)-based system. As functionality differences narrow and price points align, the debate over these virtues is getting more intense and the arguments for and against each system are getting more and more murky. This white paper discusses the “Top Ten” issues to consider when evaluating a DCS vs. building your own “DIY” distributed control system using a PLC-based architecture.
In addition to flow pressure, volume and material state, achieving and maintaining desired flow performance depends upon properly addressing some complicated design and operational issues.

When designing a system to transport powders and granules there is a wide variety of considerations. Different applications, installation environments, equipment, material characteristics and how they may change during the process are all part of the equation. While many plants aim to keep costs low and often times use old equipment for a new project this can also further compound a complex challenge. And that's not even taking in to consideration our increased awareness of the risks of an explosion and the need to avoid hazardous emissions. In this Chemical Processing Powder eHandbook, we take a look at key considerations affecting today’s best practices for transporting and processing powders and granules including:

Level measurement, which is the detection of the phase split between vapor/liquid, liquid/liquid, vapor/solid and even liquid/solid, is a key parameter in the operation and control of modern industrial processes. A reliable outcome depends on the phase conditions being relatively consistent under all process conditions. Unfortunately, the importance of level control isn’t always understood. Failure to measure level reliably has resulted in some of the most serious industrial accidents, including those at the Buncefield, U.K., fuel storage depot and BP’s Texas City refinery. In this Chemical Processing Level Management eHandbook, we discuss best practices for level management including:
How to Select the Right Liquid Level Sensor - It’s important to consider a variety of factors when choosing the type of technology
