Main Objective
The objective is to increase the knowledge in chemical and physical characterization of landfill and WWT biomethane (renewable natural gas) through an expanded sampling and analysis program. Data will be used to augment the existing database constructed through PHMSA Project 250 and further refine the associated Guidance Document. The existing database is limited and focus on trace constituents is of most interest, to assist with studies on odorant fade or instrumentation development.
Public Abstract
Objectives: GTI's goal is to help the natural gas industry establish renewable gas as a fungible zero-carbon product "fit for purpose" for injection into natural gas pipelines. Therefore, GTI proposes to continue the development of a draft guidance document for the safe introduction of renewable gas into natural gas pipelines. This project will build upon previous studies executed by GTI to further characterize and understand the chemical and biological composition of fully upgraded renewable gas. It will supply critical information for safe, reliable, and controlled delivery of biomethane into existing natural gas pipelines. Identification of the key and predominant trace constituents present in processed landfill and WWTP derived renewable gas will alleviate concern, and allow where deemed necessary, the development of instrumentation to specifically detect these compounds for proper monitoring.
Methodology: Gas samples (with an emphasis on post-clean up) will be collected from landfills and waste water treatment facilities and subjected to quantitative analytical chemical and biological tests to measure the concentration of target species. The focus is on samples from facilities that are currently producing high BTU renewable gas. The two criteria for target species are that they (1) are likely to be in the product gas and (2) have potential to impact pipeline integrity or end use applications. The analytical results obtained from the testing program will be combined with past data and used to report most probable concentrations for those constituents that are found to be present in renewable gas.
