Total Chlorine Analyzer
Measuring Chlorine is very important for oil industries and refineries. Refineries do not accept crude oil containing more than 5ppm of Organic Chlorides. Hydrochloric acid can be produced in hydro treating or reforming reactors and the acid accumulates in condensing regions of the refinery. Unforeseen concentrations of organic chlorides cannot be neutralized effectively and damage of the catalytic process can be the result.
Chlorine compounds are not known to be naturally present in crude oils and usually result from cleaning operations at production sites, pipelines and/or tanks. It is important for the oil industry to have common methods available for the determination of organic chlorines in crude oil, particularly when the transfer of custody is involved.
Chemical companies are striving for sustainable solutions and need to know the chlorine concentrations to recycle theirwaste chemicals effectively.
Organic Chlorine analysis in laboratories is based on two principles;oxidative pyrolysis and quantitative determination through microcoulometry. These techniques have been in existence for many years now because of their ease of use, absolute detection and sensitivity. The ASTM D4929 method describes this technique particularly for crude oil analysis, which is applicable to the Thermo Electron Corporation Total Chlorine analyzer (ECS3000)
The ECS3000 is a sensitive, robust and cost effective analyzer. When equipped with an autosampler, it offers extremely reliable sub ppm level 24 hour operation. This modular instrument saves benchspace and reduces investment costs because of the fast and easy switching between the chlorine and sulfur detectors. The key features of the Total Chlorine Analyzer are:
• Flexibility of design allows easy adoption of new application requirements
• Combustion in combination with microcoulometric detection is a proven technology
• Track record of successful analyses of various matrices in the concentration range from low ppm to very high ppm
• Superior to competitive techniques at the sub ppm level
• Use of high quality solid silver electrodes in the halogen capillary titration chamber
• A turbo quartz tube eliminates partial combustion and soot formation and increases the injection speed of the sample, which will generate sharper peaks and shorter analysis time.
