  • In the United States, the beet sugar industry is the most intensive user of energy, per unit value of product shipped. Approximately 2.6 x 10/sup 6/ Btu of energy are required per ton of beets processed. The increasing cost and scarcity of energy has made the industry very receptive to process changes which can reduce energy requirements for sugar production. A two-year project was undertaken to determine the feasibility of liming fresh sugar beet cossettes, prior to extraction, as a means of reducing energy consumption. Fresh Ca(OH)/sub 2/ was added to cossettes for 10 min prior to introduction into themore » diffuser (extractor). It was found that up to 3.5 x 10/sup 5/ Btu/ton of beets sliced could be saved in pulp drying and 0.45 x 10/sup 5/ Btu/ton could be saved in production of lime (13.5% and 1.7%, respectively, of current overall energy requirements of the beet-sugar process). Quality of raw juice from the diffuser was much better with limed cossettes than with control cossettes. Experimental thin juice was slightly higher in lime salts and lower in quality than controls. Liming of cossettes by dipping in a slurry of 2.6% Ca(OH)/sub 2/ gave better results than mixing of cossettes with dry Ca(OH)/sub 2/ and would be much easier to implement in an existing plant.« less
  • The Massachusetts Institute of Technology (MIT) and Siemens Corporations (SCR) are developing new chemical synthesis processes for commodity chemicals from CO 2. The process is assessed as a novel chemical sequestration technology that utilizes CO 2 from dilute gas streams generated at industrial carbon emitters as a raw material to produce useful commodity chemicals. Work at Massachusetts Institute of Technology (MIT) commenced on October 1st, 2010, and finished on September 30th, 2013. During this period, we have investigated and accomplished five objectives that mainly focused on converting CO 2 into high-value chemicals: 1) Electrochemical assessment of catalytic transformation of COmore » 2 and epoxides to cyclic carbonates; 2) Investigation of organocatalytic routes to convert CO 2 and epoxide to cyclic carbonates; 3) Investigation of CO 2 Capture and conversion using simple olefins under continuous flow; 4) Microwave assisted synthesis of cyclic carbonates from olefins using sodium bicarbonates in a green pathway; 5) Life cycle analyses of integrated chemical sequestration process. In this final report, we will describe the detailed study performed during the three year period and findings and conclusions drawn from our research.« less
  • Irrigation water supplies are becoming expensive and scarce in the western United States. As a water management tool, production functions indicating relationships between crop yields and evapotranspiration have been utilized. Models have been developed using this information. Transferability of these models is dependent upon understanding the moisture extraction characteristics for a given crop under a given set of climatic and soil conditions. Therefore, a wide range of water stress conditions must be produced. The objective of our research was to generate production function data for sugar beets (Beta vulgaris) as influenced by drought stress under irrigation.
  • Organic buffers maintain the pH of the scrubber slurry in flue gas desulfurization (FGD) as the SO2 dissolves at the air-liquid interface. Inexpensive acids with an appropriate pKa are required for this application. The pKa of lactic acid (3.86) is between that of the interface and the recirculating slurry and will make soluble calcium ion available in large amounts. Currently lactic acid is somewhat expensive for this use, but this project will develop a new source of inexpensive lactate. Microbial action during the storage and processing of sugar beets forms lactic acid in concentrations as high 14 g/L in themore » processing water. The concentrations are lower than those occurring in conventional fermentation production of lactic acids, but since a considerable amount of water is involved in the processing of sugar beets in the Red River Valley (1 million gallons/day), a substantial amount of lactic acid or calcium lactate could be recovered as a by- product for use in FGD and other applications.« less
