ANALYTICAL SOLUTIONS FOR Chemical Manufacturing Applications

For decades, our products and solutions have had a long history in industrial gas, medical gas, and chemical processing enabling detection of moisture and other rogue impurities in process gas streams, including inert, reactive, corrosive, bulk and specialty gases.  We offer solutions for quality control, optimization of analysis in chemical laboratories, and field-proven instrumentation.  Process control is the ability to monitor and adjust a process to give a desired output to maintain quality and improve performance.

Process Insights:  We are revolutionizing measurement everywhere!


Process Control

Rapid gas and liquid analyzers are able to deliver real-time control of process reactor resulting in fast, accurate process optimization for increased manufacturing yields, safer operation and reduced wear on equipment.  Enhanced process safety and meeting environmental constraints and compliances keep non-compliance fees down.  At the same time, satisfying product quality and specifications must be maintained. 

Moisture is everywhere. For dew point control, our COSA XENTAUR™ HTF™ sensor technology can be trusted where other methods have routinely failed. The stability, accuracy and life expectancy of our HTF™ sensors have set new a standard in the industry.  Dew point or moisture concentrations can have a very major effect on the quality of a process or final product.  Accurate dew point measurements are often of mission-critical nature.  We offer both online and spot control moisture measurement systems for gases and liquids suitable for use in hazardous areas.

Laboratories in the chemical industry have relied on our lab and elemental analyzers for decades. When it comes to the analysis of trace sulfur, nitrogen and chlorine, we follow ASTM methods to deliver unprecedented detection limits, accuracy and stability.  Regulatory agencies around the world have been implementing increasingly stricter fuel emissions guidelines over the past decades to limit air pollution. Regulations such as the American Tier IIIEuropean Euro 6 or the Indian Bharat VI set quantitative limits on the permissible number of specific pollutants that can be released during combustion.  Sulfur and nitrogen are both controlled under these regulations due to the health and environmental impact of their oxides: Sulfur Dioxide (SO2), Nitrogen Oxide (NO) and Nitrogen Dioxide (NO2), commonly referred to as NOx.  Accurate low-level measurement of total sulfur in natural gas and related LNG products is becoming increasingly important. The SGA-1000™ online process analyzer incorporates patented Excimer UV Fluorescence (EUVF) Technology and is ideally suited for measurement of total sulfur in a variety of applications, including low-level sulfur analysis in hydrocarbon products and process streams.

Our Stack Oxygen Analyzers are well-proven with thousands of installations in chemical and power plants, refinery process heaters, blast furnaces, coke ovens, incinerators and small boiler and furnace installations worldwide.  The small detector can easily be serviced or replaced while the probe remains in place, thus no disruption of the process is required.  Calibrations can be performed manually or automatically at user programmable intervals.  Until now, in situ measurements, used to tune boilers, were limited to O2 only. Now, there is a compact in-situ probe for combustion optimization to measure both COe and O2 simultaneously providing engineers an improved tool to lower excess air to previously unachieved levels, saving fuel costs. 

Sulfur Analysis

Sulfur is an impurity often found in petroleum products and feedstocks, typically it is removed during crude oil processing. Sulfur content is toxic and corrosive which may cause damage to refinery equipment. There are numerous methods for monitoring sulfur in a hydrocarbon stream.  Many of these methods are slow and not cost-effective.  Our Excimer UV Fluorescence technology for total sulfur analysis works in butane, diesel, liquid fuels, LNG, hydro-treaters, blenders and scrubbers, in Renewable Natural Gas (RNG) and biofuels manufacturing.

Our FGA-1000™ online process analyzer utilizes patented Excimer UV Fluorescence (EUVF) Technology to measure total sulfur in a variety of applications such as monitoring refinery flare gas and subsequent sulfur dioxide (SO2) emissions as mandated by the EPA Rule 40 CFR 60, Subpart Ja.  The FGA-1000 has the highest dynamic measurement range of any commercially available analyzer, requiring only a single point calibration without the need for additional sample valves, calibration gases or system hardware. It provides complete TRS Data resulting in the total analysis of all sulfur compounds potentially present in flare gas streams, not just the analysis of a few selected sulfur compounds as with GC-type applications.   Our patented Excimer UV Fluorescence (EUVF) Technology is incorporated into our online analyzers. 

Driven by an increasing need for trace sulfur analysis in gas and LNG products, we developed the Trace S-1000™. This remarkable online process analyzer incorporates patented Excimer UV Fluorescence (EUVF) Technology and is specifically designed for measurement of trace total sulfur content in applications that require the ultimate in low-level sensitivity, such as polymer-related applications.  One application where the Trace S-1000 has demonstrated exceptional analytical performance is the measurement of total sulfur in butane at the ultra-low range of 0-1000 ppb/vol.  Acquired test results reflect excellent linearity, precision and long-term stability for this extremely low range.  Analytical results represented were obtained utilizing an oxygen/argon blend for combustion. The Trace S-1000 provides unparalleled sensitivity and rapid response to concentration changes with a typical analysis time of only 180 seconds.

In order to measure sulfur and nitrogen content in fuels, chemicals and petrochemicals, we designed the XT-2000 laboratory analyzer for both total sulfur (TS) and total nitrogen (TN) measurements. The XT-2000 also utilizes patented Excimer UV Fluorescence (EUVF) Technology for TS measurement and proprietary Chemiluminescence (CL) technology for TN measurement offering exceptional sensitivity that does not require a vacuum pump minimizing maintenance requirements and improving analytical stability.

Laboratory, Safety and Compliance

In chemical manufacturing, fenceline monitoring is the use of monitoring technology to measure the ambient air concentration of a specific chemical at the property line of a manufacturing plant.  The details of the fenceline monitoring work practice is prescribed in EPA Test Methods 325A and 325B.  Our solutions monitor fenceline data allowing sites to have additional insight into their emission sources and their potential impact.  

Laboratory safety is governed by numerous local, state and federal regulations to reduce injury and illness.  Our oxygen deficiency monitoring solutions were designed to chemical safety, health, environmental protection and compliance.  An oxygen deficient environment is defined by the Occupational Safety and Health Administration (OSHA) as one containingless than 19.5% oxygen by volume.
