overview mason triazine represents an established and efficient liquid h2s scavenger, manufactured from monoethanolamine and formaldehyde. the resulting “scavenger” product is a hexahydro-1,3,5- tris(hydroxyethyl)triazine, and is commonly called “triazine” in the industry. mason triazine is a water soluble, aqueous-based solution. in most h2s scavenger applications, the reaction products are also water soluble, with very low toxicity characteristics and biodegradable, making this a relatively simple system to handle.

dihydrogen sulfide, h2s, is present in low concentrations in natural gas from many sources. because of its obnoxious characteristics, it is necessary to remove it during processing, before the end use. the reaction of triazinane with h2s and also its rate of hydrolysis as a function of ph and temperature. hydroxyl groups on the side chains increase the hydrophilicity of the molecule, making it ideally suited for reactions in the aqueous phase. the 2-hydroxyethyl functional groups add a more hydrophobic character, allowing for removal of h2s directly in the well itself.

other applications for mason triazine include adhesives, polymer intermediates and photographic media.

liquid scavengers an also be employed in two different processing schemes. after separation of liquid hydrocarbons and water from the gas, the liquid scavenger can be either i
