In boilers of the partial oxidation process vanadates condensate under reducing conditions and induce highly accelerated corrosion as well. The boilers or heat exchangers are usually manufactured from low Cr...

... and the reduction of reactivity with CO gas in syngas environments. The new alloy had no pits. As next step, a field test in a commercial Gas to Liquid (GTL) plant was conducted. The field test duration and temperature was 15,000 h and 520°C, giving a carbon activity of 175.8. Several pits have developed...
