Pipeline management presents challenges that are quite unique. Their long length, high value, high risk and often difficult access conditions require continuous monitoring as well as an optimization of maintenance interventions. The main concern for pipeline owners comes from possible leakages that can have a severe impact on the environment and put the pipeline out of service for repair. Leakages can have different causes, including excessive deformations caused by earthquakes, landslides or collisions mobile...
Process control of a SO2 scrubber on a ship is a challenge due to wet and corrosive gases. In such environment, extractive gas sampling systems require high levels of maintenance in order to operate correctly. OPSIS monitoring system solves this by using an optical, non-contact, cross-duct technique. A light beam is sent across the duct or stack to be measured, and the captured light is sent through an optical fibre cable to an analyser. The analyser measures SO2, CO2 and NOx concentrations using UV and IR...
The presence of humidity in a blanketing gas for sensitive instruments can cause corrosion problems, rapid changes incalibration and loss of sensitivity. The presence of oil contamination in compressors can cause similar problems.
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 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.
The purpose of determining water (moisture) content in liquid VC (vinyl chloride) is to decrease risk of corrosion and damage further downstream the process. The on-line analyzer system uses a selective H2O measurement by means of multi-wavelength infrared.
A number of treatment products are often added to prevent corrosion, scaling and fouling. Coating of sensors and other effects of these products must be taken into account when selecting analyzers. Discharge monitoring needs special attention because zero measurements must be reliable over time with little maintenance.
The purpose of determining oxygen in vinyl chloride return is to keep oxygen levels outside flammability limits. The on-line analyzer system uses a selective and fast oxygen measurement by means of a paramagnetic analyzer with corrosive resistant measuring chamber.
The purpose of determining oxygen in the oxychlorination process is to control the O2/C2H4 ratio in the reactor in order to keep oxygen levels outside flammability limits.

Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. As a result of the confinement of the waste water stations, toxic components such as H2S and...
The purpose of determining water (moisture) content in liquid EDC (ethylene dichloride) is to decrease risk of corrosion and damage to the cracking furnace. The on-line analyzer system uses a selective H2O measurement by means of multi-wavelength infrared.
Process control and emissions monitoring in a chemical plant is a challenge due to corrosive gases, high dust load, and high temperatures. To use an extractive system in this environment will demand a lot of maintenance.
Process control and emissions monitoring in cement plants, can be a challenge due to the dusty and corrosive environment. OPSIS provides an accurate system that will operate with high performance and a minimum of maintenance.
The process control of a sulphuric acid plant needs good and reliable detection of gas phase sulphur dioxide (SO2). To measure SO2 is a challenge due to the corrosive environment and high concentration of SO2. Several places in the process needs to be monitored and to transport the sample gas is difficult. A large dynamic range is needed as the SO2 concentration can vary between 15% volume and a few mg/m3. Most systems installed need a lot of maintenance, sometimes as often as every day.
Monitoring of emissions from incinerators is a demanding application for Continuous Emission Monitoring Systems. The emissions produced are highly corrosive, some of the gases are soluble and, because the waste being burnt is constantly changing, the resulting stack gas temperature varies widely.
Studies have proven that chlorine use has negative consequences due to the formation of byproducts, i.e. chlorinated organic compounds and chloramines. Irritation of eyes and mucous membranes, drying out the skin as well as “chlorine smell” are well known troubles. However, these byproducts also accelerate the corrosion in pool halls and significant risk is given by their toxicity (chloramines, combined chlorine) and/or carcinogenicity. Higher rate of asthma prevalence is one of the consequences....
