80. Shaping Effective Practices for Incorporating Sustainability Assessment in Manuscripts Submitted to ACS Sustainable Chemistry & Engineering: Catalysis and Catalytic Processes

Abstract

The principles of green chemistry and green engineering provide guidelines for choosing reagents, catalysts, and operating conditions aimed at minimizing adverse effects of catalysts and catalytic processes on human health and the environment. The use of these qualitative principles in assessing the sustainability of catalysts and catalytic process concepts remains valuable. However, the editors of ACS Sustainable Chemistry & Engineering (ACS SCE) expect greater implementation of sustainability metrics to quantify the extent to which the adverse effects of incumbent catalytic technologies are mitigated by the innovations described in manuscripts submitted to the journal. Authors are strongly encouraged to adopt these quantitative analyses not only to identify and quantify the contributions to sustainability of innovations reported in manuscripts but to also reveal economic and environmental problem areas that must still be addressed in future research to achieve a sustainable process.(1) The outcomes of such analyses also inform investments in research that will eventually lead to the commercialization of green chemical technologies. This editorial suggests guidelines for incorporating quantitative sustainability assessments in manuscripts describing catalytic processes. We have classified the guidelines based on the types of manuscripts we receive in the area of catalysis. Please note that guidelines for electrocatalysis will be provided in a separate editorial on sustainability metrics for electrochemical processes and will appear later this year.

100. Field inter-comparison of low-cost sensors for monitoring methane emissions from oil and gas production operations.

Abstract

Four solar-powered methane sensing systems with remote communication capabilities were tested for nine months at an oil and gas production site in west Texas. Sensor performance was evaluated using single blind certified gas challenges and by comparison with a continuously operated quantum cascade tunable infrared laser differential absorption spectrometer (QC-TILDAS) system. Dispersion modelling was used to estimate concentrations that would need to be detected to identify continuous and intermittent emission rates of 5-10 kg/hr from oil and gas production sites within ~50-100 m of the sensors, and these concentration thresholds were used in establishing performance criteria for the sensors. The four sensors demonstrated sufficient precision to allow for detection of emission rates of 5-10 kg/hr and had data capture rates that exceeded 80 % during the 9 months of operation. One sensor had a 100 % data capture rate, despite severe weather conditions and extended local electrical power losses. These results demonstrate that multiple commercially available sensing systems are suitable for long term methane emission monitoring in remote oil and gas production regions. [ABSTRACT FROM AUTHOR]
