| Preserving quality of life
Environmental issues, especially urban air pollution, acid rain and toxic air emissions are of increasing concern to governments and people all over the world.
Our gases help to identify and eliminate pollutants, re-use raw materials and conserve resources.
Oxygen - the elixir for waters.
In biological sewage treatment, the microorganisms need oxygen for respiration. The SOLVOX® process selectively introduces pure oxygen into waste waters and thereby considerably enhances the cleaning efficiency of sewage-treatment plants.
Nitrogen compounds that do not degrade in sewage-treatment plants cause excessive algal growth and so temporarily deplete oxygen levels in surface waters. The SOLVOX® process also helps restore the self-cleansing power of the waters and, for instance, to prevent fish from being killed.
Further areas of application for pure oxygen are:
- Wastewater transport
- Drinking water processing
- Intensive fish farming
Life-giving air
Industrial manufacturing processes often generate volatile organic compounds, which contaminate the air. The coldness of liquid nitrogen (LIN) can be utilized to condense them. This non-polluting method is especially economically attractive when the condensed components and the vaporized nitrogen can be reused.
Specialty gases
Our specialty gases are used also in the energy and water treatment sector for analytical purposes, e.g. laboratory research but also to monitor and control environment related emissions.
Laws regulate pollution control guidelines imposed on waste incinerators, power plants, industrial manufacturers and others. The need for environmental testing of the water, soil and air is therefore an important issue in today's production processes. Precision testing must accurately measure levels of Volatile Organic Compounds (VOC's), PCBs, emissions and other pollutants within the plant, and in the ambient air and surroundings.
A wide variety of plants including electric power stations, refineries, chemical plants, pulp and paper mills are required to operate Continuous Emission Monitoring (CEM) systems to quantify the amount of critical pollutants such as SO2, NOX, CO2 etc. in the facility's exhaust stream. CEM units must be calibrated on a regular basis using gas calibration standards produced under a stringent manufacturing protocol often mandated by either national law and regulations, e.g. EPA and NIST or international standards such as EN 14000. Using our mixtures assures the customer to remain in compliance with national requirements and regulations. |
