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 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.
A reliable supply of breathing air is critical for applications in the military, medical and fire fighting sectors. The presence of excess moisture in breathing air can lead to freezing in the pressure regulator and ice blocking the orifice, causing an interruption to the supply of air to the user. Such freezing effects have caused the loss of life and equipment in submarines and aircraft.
The presence of moisture in high-pressure natural gas from production wells causes pipelines and associated valves to freeze. High moisture content also leads to the formation of hydrates of the liquid hydrocarbons present, thus causing further difficulties. The moisture content of the gas also adversely affects the calorific value of the gas, thus lowering the quality and value of the product. Moisture is therefore measured at the point of extraction, at export stations, at gas storage locations and in the...
There are a lot of waterproofing systems inside a building. Their only purpose is to tight
Waterproofing systems are the major component to protect a building and the people inside against water and moisture. To be able to protect, they have to tight for the whole lifespan of the building. Unfortuneately there are a lot of reasons, why waterproofing systems can fail. Eventually, every waterproofing system starts leaking.
effective maintenance needs reliable information
To do maintenance on waterproofing systems,...
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.
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.
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.
Three Steps of CEMS:
1st Step: Gas Sampling
2nd Step: Gas conditioning and treatment
3rd Step: Measurement/Calibration
In first step, the function is to get sample gas and forward to 2nd step for treatment. During this step, it cannot block the probes and cannot result condensation of moisture. So a filter online back flushing should be equipped in this part.
The filters to be used: 1, Filter is used to ensure the stability of system and reduce the maintenance
2, Filtration Grade: usually 2 or 3 micron
CIC Photonics first applied its IRGAS technology to semi-gases when a major semiconductor equipment manufacturer, Applied Materials, requested a demo of its capability to monitor gas quality for epitaxial reactor applications; that was in year 2000. The IRGAS System met all of the technical requirements, which included ppb sensitivity for moisture as an impurity, gas cell chemical resistance to both acid and basic semi-gases, and fast concentration tracking time response.
