Levels of hydrogen in dry chlorine are monitored in hydrochloric acid synthesis by means of AppliTek’s multi-wavelength IR analyzer system. With increasing concerns over safety and efficiency in the chlorine manufacturing processes, AppliTek has investigated the use of proprietary on-line analyzer systems to monitor and control the HCl synthesis. Each of these on-line analyzer systems has been selected to control a specific part of the burner, by using techniques such as multi-wavelength infrared, thermal...
The Opsis monitoring solution in aluminium smelters is based on either DOAS or laser diode technique. The on-line, open-path systems are used for monitoring HF and sulphur dioxide in potrooms, in fence-line applications and in continuous emissions monitoring. Opsis has long experience of monitoring in aluminium smelters.
The purpose of monitoring calcium and magnesium levels in hydrochloric acid is to control brine acidification in chlorine electrolysis, which can be precisely monitored by means of AppliTek’s UPA Universal Process Analyzer.
Nitric acid HNO3 is an important intermediate reagent for production of several important end products, such as fertilizers, explosives, dyestuffs/pigments, pesticides, pharmaceuticals, photographic materials, plastics, and synthetic fibers. At nitric acid manufacturing plants, the Gasmet™ FTIR Gas Analyzer can be used to measure several gaseous components from the process stream for purposes of process control. A single system can be used to measure the high levels of nitrogen monoxide NO and nitrogen...
Levels of oxygen in dry chlorine in hydrochloric acid synthesis are monitored by means of an on-line analyzer system that can be equipped with two different measuring technologies: Alternating Pressure Paramagnetic or Tunable Diode Laser (TDL) analyzer system.
Steel, an alloy of iron and carbon (up to 2% of weight), is one of the most widely used construction materials. It is produced by Basic Oxygen Steelmaking (BOS) in a converter : oxygen is blown to form carbon monoxide (CO) and carbon dioxide (CO2) with the carbon excess of molten pig iron. Other chemical elements (such as nitrogen) that may decrease the efficiency of furnace are also removed. Finally, oxygen is replaced by an inert gas (Ar) to minimize the oxidation.
Sulfur Dioxide (SO2) is the product of the combustion of sulfur compounds and causes significant environmental pollution. The main source of sulfur dioxide SO2 in the environment are from various industrial processes such as the burning of coal in power stations, the extraction of metals from ore and combustion of fuel within automobiles.
The purpose of determining oxygen in the chlorination process is to control the O2/C2H4 ratio in the reactor in order to keep oxygen levels outside flammability limits. The on-line analyzer system uses selective and fast oxygen measurement by means of a paramagnetic analyzer with corrosive resistant measuring chamber.
Total Sulfur includes all the gases described within total reduced sulfur, as well as sulfur dioxide as these compounds are oxidised forms of sulfur. Exposure to sulfur dioxides, and other reduced sulfur based compounds can cause many harmful effects in humans including headaches, general discomfort up to death in large doses. Those with impaired heart or lung function and asthmatics are at increased risk. Sulfur dioxide, one of the major pollutants, is absorbed by soils and plants and captured within and below...
The purpose of determination of moisture in dry chlorine is threefold: prevent corrosion, prevent formation of ferric chloride and control the overall drying process. AppliTek offers two different solutions for determination of moisture: one traditional method by means of an amperometric phosphoric pentoxide (P2O5) electrochemical cell, or a more advanced technique based on tunable diode laser technology (TLDS). Both analyzer systems are installed in a compact protective corrosion resistant cabinet.
Irrigation Systems: A common problem encountered in all irrigation systems is growth of micro-organisms in the irrigation pipes causing poor flow, blockages and the potential for the spread of disease-causing organisms throughout the irrigated area, particularly fungal diseases. The micro-organisms flourishing in irrigation pipes include bacteria and fungi and, if sufficient light is present, algae. Irrigation pipes provide an ideal environment for the establishment of biofilm on the inside of the pipes.
Make more out of your mill. OPSIS tested and approved monitoring systems provide cost-effective and reliable on-line monitoring of several gas compounds, such as both high and low concentrations of methane, moisture, carbon dioxide and hydrogen sulphide, at several locations.
The purpose of determining hydrogen chloride in liquid EDC (ethylene dichloride) is to protect EDC against corrosion by HCl during transport or storage. For all other analytical solutions in the chlorination process, please browse the On-line Analyzers Suite under Products & Solutions.
The purpose of determining impurities in liquid EDC (ethylene dichloride) is a quality control measure to avoid contamination of EDC and off-spec product batches. For all other analytical solutions in the chlorination process, please browse the On-line Analyzers Suite under Products & Solutions.
The determination of oxygen in hydrogen is a safety critical measurement to keep the hydrogen mixture below explosion limits during chlorine electrolysis. AppliTek’s analyzer system is engineered to detect oxygen in an early stage and safeguard the compression process, with a small footprint allowing easy integration in any production site.
In the normal course of operation, hospitals generate a variety of waste products which are not suitable for normal disposal. While some or most hospital waste may be harmless, it is difficult to distinguish such harmless waste from infectious waste. As a result, all of the waste from a hospital must be treated as if it is harmful.
The recent COP 21 meeting reexposed the need for global coordination to monitor Green House Gases (GHG) as well as emissions of ChloroFluoroCarbons (CFC). Networks of sensors have been deployed over the Earth to measure concentration of gases such as methane, carbon monoxide, ethane, carbon dioxide, nitrous oxide, nitrogen oxide and dioxide (NOx)… Such task requires instrument with not only ultra high accuracy but also ultra high precision. Our QCNose Instruments have been designed for such operations...
The Opsis monitoring solution for mining and smelting applications is based on either DOAS or laser diode technique. Opsis non-contact monitoring solutions are very well suited for applications in the Mining and Smelting Industries, as the flue gas conditions often involves high temperatures and high dust concentrations. The on-line, open-path systems are used for monitoring HF, sulphur dioxide, SO3 and HCl in potrooms, in fence-line applications and in continuous emissions monitoring.
While land-based industry has been subject to strenuous emissions regulations over the past decades, air emissions from sea-going ships’ machinery has so far been largely unregulated. As a result, according to EU statistics, ships have become the single biggest source of sulphur dioxide (SO2) within the EU. The US EPA (US Environmental Protection Agency) reports similar findings, i.e., that the proportion of air pollutants released which can be attributed to the shipping industry is increasing. MARPOL Annex...
