Title: Indiana Corn Dry Mill

Abstract

The goal of this project is to perform engineering, project design, and permitting for the creation and commercial demonstration of a corn dry mill biorefinery that will produce fuel-grade ethanol, distillers dry grain for animal feed, and carbon dioxide for industrial use.

  • Biomass from plants can serve as an alternative renewable energy resources for energy production. Low densities of 40–60 kg/m3 for ground lignocellulosic biomass like corn stover limit its operation for energy purposes. The common drawbacks are inefficient transportation, a bigger storage foot print, and handling problems. Densification of biomass using pellet mill helps to overcome these limitations. This study helps to understand the effect of binder on high moisture biomass with a focus on the quality (density and durability), the pelleting efficiency and the specific energy consumption of its pelleting process. Raw corn stover was pelleted at high moisture ofmore » 33% (w.b.) at both varying preheating temperatures and binder percentage. The die speed of the pellet mill was set at 60Hz. The pellets produced were analyzed and showed higher moisture content. They were further dried in a laboratory oven at 70°C for 3-4 hr bringing the pellet moisture to <9%. The dried pellets were evaluated for their physical properties like unit, bulk and tapped density, and durability. Furthermore, the results indicated increasing the binder percentage to 4% improved the physical properties of the pellets and reduced the specific energy consumption. Higher binder addition of 4% reduced the feedstock moisture loss during pelleting to <4%, which can be due reduced residence time of the material in the die. On the other hand the physical properties like density and durability improved significantly with binder addition. At 4% binder and 33% feedstock moisture content, the bulk density and durability values observed were >510 kg/m3 and >98% and the percent fines generation has reduced to <3%. Also at these conditions the specific energy consumption was reduced by about 30-40% compared no binder pelleting test.« less
  • A total of 197 headwater and wading stream sites were sampled in 1990 to develop and calibrate an Index of Biotic Integrity for use in Indiana. Separate metrics were developed based on previous works to quantify water quality degradation characteristics. Separate scoring criteria and batteries of metrics were developed for Lake Michigan recognizing two divisions. Divisions are based on the presence of salmonid species. Water resources were evaluated indicating improved water resource quality in the Kankakee and Iroquis Rivers with increasing drainage area, while declining quality occurred in the Lake Michigan drainage. Site specific data, scoring criteria, and guild definitionmore » are included in the appendix.« less
  • The Clean Water Act Amendments of 1987 mandate the development of biological criteria for evaluating the nation's surface waters. The requirements of Section 304(a) was implemented in Indiana to determine water resource degradation. A total of 197 headwater and wading stream sites were sampled in the Central Corn Belt Plain ecoregion in order to develop and calibrate an Index of Biotic Integrity for use in Indiana. Based on inherent variance within the ecoregion, sub-basins were established based on the concept of natural areas as recognized by Homoya et al. (1985). Site specific data; locality information; and species specific scoring criteriamore » for tolerance classification, trophic guilds, and reproductive guilds are included in the appendix.« less
  • The principle planning objective was the development of a renewable resource energy production facility for Cagles Mill Lake and the surrounding study area to be of benefit for a 100-year period of analysis. All plans studied are economically infeasible due primarily to the cost of the conveyance system needed to deliver the water to the powerhouse. The maximum capability of a house power unit in the center gate opening of the control tower is almost 250 KW. It is recommended that the study of the feasibility of small scale hydropower at Cagles Mill Lake, Indiana be terminated. It is recommendedmore » that a small station power unit, having an installed capacity of about 250 KW, be designed and installed in the existing tower at the earliest possible date to provide power for project facilities.« less
