Poland:
Gases optimize manufacturing processes A contract was signed with the Toruń waterworks for the supply of liquid oxygen for ozone production. Tests with ozone for water treatment also took place in two other waterworks.
Czech Republic:
Full service for Spolchemie Messer Technogas supplies liquid nitrogen and oxygen to Spolchemie in Usti nad Labem. Spolchemie also takes nitrogen from a Messer PSA plant for inerting. In 2006, the Czech subsidiary augmented the biological sewage treatment plant with oxygen, which involved the delivery and commissioning of three injection systems.
Hungary:
Oxygen prevents unpleasant odors Gödöllő, a town near Budapest, was having a problem with unpleasant odors in some areas, particularly in summer. The reason for this was putrefaction in the wastewater mains. Messer Hungarogáz enriched the wastewater of the sewage treatment plant with oxygen, which led to a marked improvement in the air quality within just one day. Oxygenation also proved to be an economically optimal solution.
Removal of soil contamination On the site of a former aluminum oxide plant, the soil had become contaminated with alkaline deposition. The required soil clean-up was supported by Messer Hungarogáz through, among other things, the supply and application of liquid carbon dioxide. During the soil clean-up, the groundwater that was pumped out of the ground was neutralized as far as possible with mineral acid, while lances were also used to inject gaseous carbon dioxide below the groundwater table. The carbon dioxide reduced the pH of the contaminated water in a particularly eco-friendly way.
France:
Good technology references At Sanofi, Messer France was able to install a reference plant for Messer’s DuoCondex process for waste gas cleaning with nitrogen.
Belgium and the Netherlands:
For good paper The paper industry is a completely new line of business. Already, three customers – Smurfit, Stora-Enso and Sappi – have been won for the application of CO2 for processwater neutralization. This avoids the use of other additives and improves the paper quality.
