Executive Summary
The objectives of this work included the evaluation of alternative emissions estimation methodologies, determination of the key operating parameters that influence methane emissions, and identification of emissions reduction technologies applicable to these process units and their associated marginal abatement cost. The study involved a review of both glycol dehydration units (typically using triethylene glycol- TEG) and refrigeration plants (using ethylene glycol- EG). Primary data collection from UOG companies/facilities as well as secondary data collection from a number of other sources were used to inform the study results, including total installed costs and market penetration of emissions control technologies.
