Title: Final Report

Abstract

Contaminants present in paper recycling mills can degrade product properties and can also lead to substantial downtime. Of these, adhesive material such as hot melts and pressure sensitive adhesives are especially troublesome. These are known as “ stickies ” and their handling and re- moval requires process equipment such as screens and cleaners as well as chemical additives. In the preceding phase of the project we demonstrated that firing an underwater spark in a tank of stock reduces the tack of the stickies and reduces their impact. The present phase was to demon- strate the technology in full-scale trials, address any issues that might arise, and commercialize the process. Trials were run at the Appleton papers mill in West Carrollton, OH, the Graphics Packag- ing mill at Kalamazoo, MI, Stora Enso mills at Duluth, MN, and Wisconsin Rapids, WI, and the Jackson Paper mill at Sylva, NC. It was shown that the sparker not only detackified stickies but also increased the efficiency of their removal by centrifugal cleaners, improved the effectiveness of dissolved air flotation, and increased the efficiency of flotation deinking. It is estimated that the sparker improves the efficiency of hydrocyclone cleaner, deinking cells and dissolved and dispersedmore » air flotation units by 10-15%. This translates to a corresponding energy benefit in operating these units. The technology has been licensed to Eka Chemicals, a division of Akzo Nobel.« less

  • A process design for a CLEAN COKE commercial facility has been developed, based on information obtained from completed bench-scale and process-development studies. The design envisages a plant, based on Illinois No. 6 coal, and with a 21-year operating life. A coal feed rate of 12.43 million tons per year, raw basis (8.9 million tons MAF basis), is comprehended. Carbonization encompasses a preoxidation/drying stage followed by two stages of devolatilization to a maximum temperature of 1400/sup 0/ F. This yields a product char with residual volatile-matter and sulfur contents of 2 and 0.78 percent, respectively. The char is converted to amore » pelletized formcoke in a sequence of operations including disk pelletization, air curing, and final coking. Hydrogenation is carried out noncatalytically at 870/sup 0/F and 2700 psia pressure, with a 1-hour residence time. Products of hydrogenation are separated by a vapor-stripping technique, and the carbonaceous residue is processed through a slagging gasifier to produce additional hydrogen for the process. The products from the plant include, on an annual basis, 3.6 million tons of coke, 2.9 billion pounds of chemical feedstocks, and more than 33 trillion Btu of liquid fuel.« less
  • The Western Study Area (WSA) report integrates the study area history, geology, and hydrology with the results of soil, surface water, ground water, air, biota, and structures investigations to define the nature and extent of contamination of the western part of RMA. The WSA includes all of sections 3, 4, 9, and 33 and portions of sections 28 and 34. The WSA is a relatively undeveloped region that was used for railroad transport, vehicle maintenance, and waste disposal. The chemical sampling included analysis of 1081 samples from 388 borings, three soil gas programs, and monitoring of 369 wells. The dominantmore » contaminant group is volatile halogenated organic compounds. The volume of potentially contaminated soil is estimated to be 178,000 cubic yards.« less
  • This report contains two separate parts: Characterization of the Radon Source in North-Central Florida (final report part 1 -- final project report); and Characterization of the Radon Source in North-Central Florida (technical report). The objectives were to characterize the radon 222 source in a region having a demonstrated elevated indoor radon potential and having geology, lithology, and climate that are different from those in other regions of the U.S. where radon is being studied. Radon availability and transport in this region were described. Approaches for predicting the radon potential of lands in this region were developed.
  • The objectives of this work were to determine if the numbér of fiber cell initials varied genetically and to compare the number of initials with that of mature fibers obtained at harvest time. The method used to count the number of fiber cell initials is direct, simple, quick and done while the plant is growing. In contrast, the currently used commercial process is indirect and needs large amount mature fibers gathered at harvest time. However, all current work on cotton yield is based on fiber numbers obtained by the indirect commercial process. Consequently, it was necessary to compare results obtainedmore » from the two methods using the same plants as the source of material. The results show that the number of fiber initials per ovule differed significantly (P>0.05) for seven cultivars in 1995 and 1996. AIso, a 1997 study shows the number of fiber initials varied by 15% over boll positions and environments, with rankings among cultivars generally consistent across boll positions and sampling times. Finally, although there were differences among cultivars for initial fiber cell number, all cultivars had nearly the same number of mature lint fibers per seed. This last finding is significant. It indicates that the rate of fiber cell initiation varies among cultivars; the lower the rate, the greater the difference between the number of initials and the number of mature fiber cells. If the rate of fiber initiation is relatively high, the number of initials and mature fibers differs by about 11%; if it is low, the difference is as high as 31%. Cotton breeders may be able to use genetic differences for the number of fiber initials and/or the rate of fiber cell initiation in crop improvement programs.« less
