Highly Accurate Continuous Emissions Monitoring
Continuous emission monitoring systems (CEMS) are used by manufacturers and producers that have combustion and other forms of emissions releases as part of their processes. These systems provide the information required for regulatory reporting. A recent news...
Improving Quality for Food and Beverage Producers
Consumers have come to expect only the highest quality when it comes to the food and beverages they purchase. Automation has driven the variability of the products way down over the years. But even with these improvements, the average food & beverage producer...
Measuring and Analyzing Gas Components Across Broad Range
Many applications including emissions monitoring, ethylene purity, ammonia slip, hydrocarbon gas composition, and more require the measurement of the concentration of various components in a gas mixture. One technology used to perform this measurement is tunable diode...
Laser Gas Analyzers for Optimizing Ethylene Production
The ethylene molecule consists of a double bond between carbon atoms and four hydrogen atoms bonded, two to each carbon atom. Per the Wikipedia Ethylene entry, it: …is widely used in the chemical industry, and its worldwide production (over 150 million tonnes in...
Continuous Emissions Monitoring for Energy Optimization
For process manufacturers, the energy bill can up to 40-60% of the total operating budget. One way to optimize the energy expended is with Continuous Emissions Monitoring Systems (CEMS). Many people think of CEMS as something used for emissions regulatory reporting to...
Disruptive Innovations in Automation
Technology advances have disrupted many markets including photography, music, video and communications to name just a few. These disruptive innovations have improved usability and reduced costs for those taking advantage of the technology advancements. In our world of...
Continuous Gas Analyzers for Emissions, Gas Analysis and Compliance
The combustion process leads to emissions which must be measured and reported to regulatory authorities in jurisdictions where process manufacturers and producers operate. Technologies such as Quantum Cascade Laser (QCL) and Tunable Diode Laser (TDL) are used to sense...
Optimizing Ammonia Usage in NOx Emission Reduction Processes
Mono-nitrogen oxides (NOx) including NO and NO2 are byproducts of combustion where it occurs in the presence of nitrogen. Since the composition of the atmosphere is 78% nitrogen, this would include most places where this combustion occurs. These NOx gases: …react to...
