This paper focuses on the overall column design parameters for the removal of H2S from natural gas with the emphasis on the effect of the sparger/distributor design on achieved Gas holdup and its potential effect on scavenging efficiency. Numerous oil and gas producers utilize triazine based liquid scavengers for H2S removal for applications up to approximately 2 tons of H2S removal per day (4409 lbs of H2S per day). Column designs are generally simplistic and usually consist of a vertical column, a gas inlet, liquid scavenger inlet and gas/scavenger outlet. Various configurations exist for example; continuous cocurrent, continuous counter-current and dual systems. What they all have in common is a sparger or distributor through which the gas enters the column. Numerous studies have been conducted on bubble characteristics through a bubble column, specifically gas holdup as it relates to superficial gas velocity. In most studies the liquid phase is water, the effect of liquid viscosity, liquid and gas density is well documented. Relatively few studies have been conducted on sparger design and its effect on Gas holdup in liquid triazine based applications.

Laboratory performance evaluations and field data of the non-triazine based high temperature stable H2S scavenger will be discussed. The new H2S scavenger acts as a corrosion inhibitor and is thermally stable up to 200°C. It does not promote scale as observed during dynamic scale loop evaluations.
