From monitoring impurities in vents, stacks, air or water to point source or area monitoring, automatic and on-line measurement is an important tool. This type of measurement will detect, quantify and assist in reducing emissions. Siemens analytical products are utilized for many of these measurements.
Feed millers from around the world use Perten Instruments´ analytical equipment to improve efficiency and profitability. The DA 7200 At-line and DA 7300 On-line Near-Infrared (NIR) Analysis Systems are at the heart of it all. They are highly accurate and versatile, and provide great savings through better raw material usage and process optimization. In most cases the cost savings mean that the investment is paid back in only a few months.
The production of construction materials has a long tradition. Thus the production processes in some places have not yet been adapted in all areas to the present state of art. With our measuring systems we are improving and modernizing production processes in cement and mineral plants as well as in the construction material chemistry. Continuous mass flow measurement, online moisture measurement and dust monitoring systems are used frequently in this sector.

The aim is to ensure quality during the manufacturing process, to improve the safety of the plant and to increase environmental protection. In the last years, we have been able to improve the processes with our technologies in a wide range of chemical applications with our experience. Our online operating systems are maintenance-free and operate reliably with almost all bulk solids. No matter whether abrasive, corrosive or otherwise...
AppliTek’s analytical solutions for efficient wet etching processes can be used in the semiconductor industry where latest generation fabs have only accelerated the needs for process monitoring. With the increased speed of processing, precise chemical concentration control is becoming crucial to wafer processing in order to obtain consistency and more cost-effective manufacturing of integrated circuits.
During the last two decades AppliTek was able to build up a unique expertise in the design, manufacturing and commissioning of on-line analyzer systems in the chlor-alkali industry. Our know-how in the critical processes is contributing to the Responsible Care Principle, while our goals for your production plant are self-evident: assure safety, enhance efficiency and increase net profits.
Acidity in vinyl chloride can be quantified by measurement of hydrogen chloride (HCl) levels, serving as a quality measure and preventing corrosion of the storage and handling equipment. For this reason it is recommended to monitor and control HCl by means of AppliTek’s UPA Universal Process Analyzer technology.
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.
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.
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.
Determining chlorinated organics in waste water of the oxychlorination process is for reasons of environmental compliance. The on-line analyzer system uses a scrubber system where a carrier flow is bubbling through the water. The vapor phase is measured by a Flame Ionization Detector (FID) and is a measure for chlorinated organics of the water.
The purpose of determining ethylene in the chlorination process is to minimize ethylene losses by feedback control of C2H4 / Cl2 ratio in the chlorination reactor. The on-line analyzer system uses selective C2H4 measurement by means of multi-wavelength infrared with automatic optical span possibility. For all other analytical solutions in the chlorination process.
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.
Levels of chlorine in dry chlorine in hydrochloric acid synthesis are monitored by means of AppliTek’s multi-wavelength UV analyzer system. Hydrochloric acid or HCl is one of the primary products of the chlor-alkali industry and commonly produced by the exothermic reaction of hydrogen and chlorine inside a burner. 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 HCl...
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...
Levels of iron in liquid hydrochloric acid (HCl) are precisely monitored by means of the EZ-HCl analyzer system. Iron oxides that dissolve in the HCl can lead to the formation of ferrous chloride (FeCl2) and compromised purity of the end product. 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...
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.
Determining levels of CO and CO2 and their respective ratio in the oxychlorination reactor contributes to overall process efficiency. The on-line analyzer system uses a selective CO/CO2 measurement by means of multi-wavelength infrared with automatic optical span possibility.
