The purpose of this paper is to define and evaluate the key sequential steps required in transmitting, sampling and speciating sulfur laden NGL streams, in order to recommend and install absorbents capable of passing pipeline copper strip tests. An evaluation of the sulfur adsorption characteristics of specific sample containers will be given along with sample container material recommendations. A description of speciation instrument options will be followed by a description of the method for choosing and testing absorbents from an appropriate range to remove the sulfur species present in the speciated NGL. A case study will be discussed demonstrating sulfur absorbent selection after a sour liquid is sampled, speciated and treated using an absorbent in a plant slipstream treater in the field. The effect of sulfur species, concentration, temperature and pressure on the candidate absorbent will be discussed.
