Review of tribological sinks in six major industries

Description: Friction and material wear occur throughout all industries and are involved in many processes within each industry. These conditions make assessing tribological activity overall in industry very complex and expensive. Therefore, a research strategy to obtain preliminary information on only the most significant industrial tribological sinks was defined. The industries examined were selected according to both the magnitude of overall energy consumption (particularly machine drive) and the known p… more

Energy and protein production from pulp mill wastes. Progress report, June 15, 1977--September 15, 1977

Description: Experiments conducted during this past quarter demonstrated the decided difference both in amount and composition of the gas produced from the fermentation of ozonated versus unozonated yeast-plant SSL. Gas from ozonated SSL averaged over 80% methane content while unozonated effluent was mostly carbon dioxide. Gas production rates and retention time studies indicated that the fermentation was substrate-limited. Preliminary tests using supplemental carbon sources have verified this. The success … more

Method for evaluating the potential of geothermal energy in industrial process heat applications

Description: A method is presented for evaluating the technical and economic potential of geothermal energy for industrial process heat applications. The core of the method is a computer program which can be operated either as a design analysis tool to match energy supplies and demands, or as an economic analysis tool if a particular design for the facility has already been selected. Two examples are given to illustrate the functioning of the model and to demonstrate that results reached by use of the model… more

Technology trends in econometric energy models: Ignorance or information

Description: Simple time trend variables in factor demand models can be statistically powerful variables, but may tell the researcher very little. Even more complex specification of technical change, e.g. factor biased, are still the economentrician's measure of ignorance'' about the shifts that occur in the underlying production process. Furthermore, in periods of rapid technology change the parameters based on time trends may be too large for long run forecasting. When there is clearly identifiable engine… more

Investigation of freeze concentration as a process for industrial energy conservation in black liquor, acetic acid, and citrus juice applications. Final report

Description: One of the largest consumers of energy in industrial processing is the equipment that concentrates weak aqueous solutions to stronger more sellable or reusable concentrations. The technical and economic feasibility of applying freeze concentration (that is, crystallization and removal from solution of pure solvent - water) as an alternative to heat evaporation (or distillation) to three industrial applications is established. For each of the applications - pulp mill black liquor concentration, … more

Energy and protein production from pulp mill wastes. Progress report, September 15, 1977--December 15, 1977

Description: Effort during the past quarter was directed at two specific objectives. First, the conversion of the protein production experiments from batch to continuous operation and, second, the identification of growth stimulants to increase methane yield. Early in the project, yeast production ranging from 0.5 to 5.0 grams of dry yeast per liter had been obtained in batch cultures. Highest yields were consistently attained on SSL (spent sulfite liquor) which had been ozonated for only 10 minutes. Contin… more

Energy and protein production from pulp mill wastes. Annual report, June 15, 1976--June 15, 1977

Description: The effect of ozone treatment on spent sulfite liquor yeast plant effluent was studied. A 500 ml capacity packed column was constructed to efficiently react ozone with spent sulfite liquor (SSL) on a continuous flow basis. The SSL was reacted at pH 3.0 for 3 hours averaging an ozone consumption of 12.8 gm/1. It was found that pH tended to decrease during ozonation indicative of the formation of oxalic and other organic acids. Chemical oxygen demand (COD) decreased 13 percent from 101,000 to 88,… more

Industry process models: applications for market penetration and energy use projections

Description: The Brookhaven National Laboratory pulp and paper industry process model is used to project market penetration of energy conserving technologies and purchased energy for the paper industry. The risk adjusted discount rate concept is incorporated to penalize the capital costs of unproven technologies. For this analysis, the production-cost minimization objective is relaxed to explore near-minimum cost industry alternatives. Allowing paper production to include all possibilities within 1% of the … more

Model of penetration of coal boilers and cogeneration in the paper industry

Description: A model has been developed to forecast the penetration of coal boilers and cogeneration of electricity in the paper industry. Given the demand for energy services (process steam and electricity) by the paper industry, the Penetration Model forecasts the demand for purchased fuel and electricity. The model splits the demand for energy service between energy carriers (coal, fuel oil/natural gas, bark, and spent liquor) on the basis of the installed capacity of 16 types of boilers (combinations of… more

Energy and protein production from pulp mill wastes. Final report, 15 Jun 1976-14 Jun 1979

Description: The goal of this research was to convert the organics and sulfur in sulfite spent liquor (SSL) now classified as pollutants from sulfite pulp mills, into synthetic methane and protein by means of a combination chemical-biological process. Ozonization was used to break the high molecular weight lignosulfonate molecules present in SSL into lower weight fractions which could be metabolized by methane-producing bacteria and protein-producing yeast. Ozonization experiments showed that this treatment… more
