  • Every day countless kilometres of steel pipelines are installed worldwide for the most varied civil and industrial uses. They form real networks comparable to a system of road networks, which, although not so obvious, are definitely much more intricate and carry fluids that have become essential for us. To comply with technical specifications and fulfil the necessary safety requisites, special materials and welding processes which have evolved with the sector have been developed in recent years.

  • The solid product is a wet sludge of calcium sulfate which can be disposed of easily. So FGD does not eliminate pollution. What it does accomplish is to convert a big problem (emission of large volumes of air contaminated by harmful levels of gaseous SOx) into a small problem (collection and disposal of scrubber sludge). Dealing with the problem of air pollution is not cheap. An FGD system installed in a newly constructed power plant represents about one-third of the total cost of building the entire plant.

  • Generalities: The formation of gaseous O2 at the anode of an electrolytic cell containing an aqueous electrolyte solution is the most frequent electrode reaction. It has immense practical implication because it always accompanies the electrolytic production of H2 in water electrolyzers, the cathodic deposition of metals in metal electrowinning processes, and the application of a cathodic current in cathodic protection operations, and it takes place at the negative pole of metal–air power sources upon recharging. ...
