Centrifugal compressors for the synthesis loop and refrigeration services were also implemented, which provided significant cost. In this reaction, ammonia is oxidized to [21] This situation repeated in September 2021 due to a 250-400% increase in the wholesale price of natural gas over the course of the year. Ammonia is especially prevalent in anoxic sediments because nitrification (the oxidation of ammonia to nitrite [NO2-] and nitrate [NO3-]) is inhibited. Channel alteration can result in decreased nitrogen uptake within the stream, while decreases in riparian and watershed vegetation associated with agriculture and urbanization can reduce nitrogen uptake in the surrounding landscape. At each site ammonium was introduced at the upstream portion of the study reach.
