The purpose of determining impurities in dry chlorine (after compression) is a quality control measure to avoid contamination and off-spec product batches. Alternatively, chlorine purity can also be determined by measuring absolute levels of chlorine in dry chlorine, by means of multi-wavelength UV analysis.
Chlorine levels in liquid hydrochloric acid (HCl) are precisely and safely monitored by means of AppliTek’s EZ-HCl process analyzer. On-line measurement of chlorine in liquid HCl guarantees the purity of the end product. An additional possible reason for the measurement is that chlorine is an indicator for the amount of excess hydrogen in the synthesis of hydrochloric acid.
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.
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 chloride process of titanium dioxide (TiO2) pigment manufacture first converts titania-containing ores to TiCl4 via a carbochlorination reaction at a high temperature in a chlorinator in the presence of chlorine gas and petroleum coke added as a reductant.
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 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 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 determining ferric chloride in liquid EDC (ethylene dichloride) is to avoid contamination of EDC and decrease risk of corrosion to production units. For all other analytical solutions in the chlorination process, please browse the On-line Analyzers Suite under Products & Solutions. Background: Ferric Chloride (FeCl3) is used as catalyst in the EDC reactor. The FeCl3 colors the EDC with a yellow / brown color which is measured with an opacimeter.
ALUMINUM INDUSTRY: Performed a range of test measurements required by the promulgation of the Secondary Aluminum MACT standards. Testing included measurements of Hazardous Air Pollutants for establishing Area vs. Major Source Determinations, as well as dioxin/furan compounds associated with chlorine emissions from fluxing operations.
