Meet SCS Engineers’ carbon sequestration and deep well injection experts at BOOTH 729 at the 39th annual International Fuel Ethanol Workshop (FEW) & Expo, June 12-14, in Omaha, Nebraska.
The FEW provides cutting-edge content and unparalleled networking opportunities to the global ethanol industry within a dynamic business-to-business environment. It is the largest, longest running ethanol conference in the world—and is powered by Ethanol Producer Magazine.
The FEW delivers timely presentations with a strong focus on commercial-scale ethanol production – from quality control and yield maximization to regulatory compliance and fiscal management. The FEW is also the ethanol industry’s premier forum for unveiling new technologies and research findings. The program extensively covers cellulosic ethanol while remaining committed to optimizing existing grain ethanol operations.
Abstract: Carbon Capture and Storage (CCS) is becoming increasingly attractive due to growing climate change concerns as well as tax incentives related to conducting CO2 capture. Facilities that capture CO2 may consider storing captured CO2 via geologic sequestration (GS). GS at a given location requires a Class VI Underground Injection Control (UIC) permit for a Class VI UIC well(s) to inject supercritical CO2. These permits require multiphase flow modeling to delineate both the extent of the supercritical CO2 plume and areas that exceed a critical pressure threshold as a result of injection. We have found numerical modeling is also valuable during project scoping to provide a sense of what the total CO2 storage capacity may be for a given project. To determine long-term storage capacity, CO2 trapping (storage) mechanisms must be considered, including structural/stratigraphic, capillary, solution, and mineral trapping (depending on geochemistry). Solubility trapping appears to be the ultimate trapping mechanism for injected CO2 under most geochemical conditions; therefore, solution storage efficiency will be a key metric for project scoping. Solubility trapping occurs when the CO2 dissolves from its separate, buoyant phase into formation pore water. If the total available pore space for the project and the solubility limit of CO2 can be estimated, then the total solution storage capacity can also be estimated. Then numerical modeling can be used to estimate design and operational parameters to quickly examine under what conditions the most efficient use of pore space occurs. In this example, we investigated what factors may promote solution storage efficiency using a multiphase flow model. This includes how supercritical CO2 injection rate, duration, and location(s) affect solution storage efficiency. This simplified study concluded that injection rate, duration, and location(s) all affect solution storage efficiency. Project-specific considerations need to be incorporated into the model in order to determine the conditions ideal for maximizing solution storage efficiency.
The 2023 FEW program has four concurrent tracks and three additional events:
The FEW typically draws industry professionals from all 50 states and more than 30 countries. Upwards of 550 biofuels producers from 209 facilities all over the world attend each year.
The 2023 FEW proudly visits Omaha, NE. We look forward to seeing you there!
