Supercritical Fluid Extraction on the Vanguard: Advances and Innovations

28th Green Chemistry & Engineering Conference

Call for Abstracts

Supercritical fluid extraction (SFE) is a powerful chemical processing technique that goes beyond the green chemistry principles of environmentally friendly solvents and essentially complete solvent recovery and reuse. While the most popular supercritical fluid is carbon dioxide, small molecule hydrocarbons, alcohols, ketones, nitrogen containing compounds (e.g., N2O and NH3) and mixtures are finding increasing applications. The ability to selectively tune temperature, pressure, polarity, and other physical properties of the supercritical solvent is attractive to a diverse audience and recent innovations in methodologies and technologies keep the field on the vanguard. Metrics, scalability, and dynamic process control and real-time monitoring enhance the range of accessible conditions and expand applications. This session highlights the practice gaps of extracting thermally-sensitive and bio-active compounds, scalability, techno-economic analysis of initial cost, efficiency, and scale-up, lack of universally applicable conditions, operator training and safety, regulatory standards, and AI and machine learning predictive modeling.

Details below on 1) indoor air quality, 2) methane, 3) carbon dioxide, 4) misleading information, and 5) SARS-CoV-2 and COVID-19 Resources.

1) Indoor Air Quality

Ensure the ventilation on trains and busses is operating. Carbon dioxide should not exceed 1,000 ppm CO2 except for brief periods. Outside fresh air is 423 ppm CO2. Increase air exchange and use MERV 13 filters.

2) Methane

The current global market value of methane (natural gas) is $105 billion and is projected to grow at least 5% per year. Methane is second in terms of contribution to the greenhouse gas inventory, between carbon dioxide and nitrous oxide, and accounting for about 30% of the global warming since the industrial revolution; the atmospheric concentration of methane is increasing faster than at any time since record keeping began in the 1980s. Methane’s savior is its mean atmospheric lifetime of about ten years, providing a near-term opportunity to mitigate its atmospheric concentration, the imbalance between natural sources and sinks.

“Based on average natural gas prices from 2017 to 2021, we estimate that around 40% of methane emissions from oil and gas operations could be avoided at no net cost because the outlays for the abatement measures are less than the market value of the additional gas that is captured. Based on the record gas prices seen around the world in 2022, we estimate that about 80% of the options to reduce emissions from oil and gas operations worldwide could be implemented at no net cost. Around USD 100 billion in investment is required to 2030 to deploy all methane abatement measures in the oil and gas sector. This is less than 3% of the net income received by the oil and gas industry in 2022.”

3) Carbon Dioxide

Globally, approximately 50 billion tonnes (50 Gt) of greenhouse gases, as measured in carbon dioxide equivalents, are emitted directly into the atmosphere each year. Energy use (electricity, heat and transport) accounts for 73.2%, direct industrial processes 5.2%, waste 3.2%, and agriculture, forestry and land use 18.4%.

4) Coping with Misleading Information

Information flows to us via many channels. Misleading information is more than an inconvenience, it can create chaos and delay or prevent decisions in public health, environmental action, and the market. Scientific literature enjoys longstanding guardrails to publish peer-reviewed reports and issue retractions when warranted. The popular press and social media proffer in real time and mis- and dis-information can spread like wildfire; if unchallenged, societal polarization can increase and confidence in public institutions can erode. We need to help society understand complex social and technical issues. Frame your activities around who is creating the content, who is amplifying the content, and who is affected by the content.

5) SARS-CoV-2 and COVID-19

The coronavirus is airborne, an aerosol. Filters, masks, and vaccines help stop spreading.
