Triazine based H2S scavenger is very efficient in removing corrosive and poisonous H2S from liquid and/or gas phases and its offensive smell of rotten egg. It can be used in mixed production, downhole, subsea, well head, bulk storage tanks and produced water streams. The product can be added to the fluid immediately before pumping. For vapour phase the reaction is directly proportionate to the liquid reaction and can be found by calculating the ppm weight of H2S in the atmosphere. The dosages however vary, depending on the type of stream i.e., mixed or single stream, temperature, flow regimes, contact time, equipment design and type of stream (i.e., mixed or single stream). It is used in oil and gas industry and water treatment as biocide and to remove H2S gas. There are other industries where Triazine is which are specialty chemical manufacturing, making different blends in lubricant industry, offshore chemical.
