Energy use and distribution in the pulp paper and boardmaking industries

Description: The Pulp, Paper and Boardmaking Industries (PPBI) are major energy consumers in the U.S. economy, ranking fourth among all industry groups in this respect. Including the consumption of waste streams generated within the industry's manufacturing processes, the overall energy consumption in 1972 was 2.2 x 10/sup 15/ Btu (2.2 quads or 2.3 x 10/sup 18/ joules). Energy consumption is almost equally distributed between pulpmaking and recovery or regeneration of pulping chemicals, on the one hand… more

Energy and protein production from pulp mill wastes. Progress report, September 15, 1976--December 15, 1976

Description: Significant progress was made during the past quarter in establishing the operability and reliability of major pieces of equipment needed for the production of protein and methane from spent sulfite liquor (SSL). Batch ozonations of SSL were conducted at times varying from 1 to 6 hours at pH's in the range of 10 to 2. These screening experiments consistently indicate that low ph's favor the breakdown of SSL into organic fragments which are more easily assimulated by micro-organisms. Approximate… more

Testing of an advanced thermochemical conversion reactor system

Description: This report presents the results of work conducted by MTCI to verify and confirm experimentally the ability of the MTCI gasification process to effectively generate a high-quality, medium-Btu gas from a wider variety of feedstock and waste than that attainable in air-blown, direct gasification systems. The system's overall simplicity, due to the compact nature of the pulse combustor, and the high heat transfer rates attainable within the pulsating flow resonance tubes, provide a decided an… more

Energy and protein production from pulp mill wastes. Progress report, December 15, 1976--March 15, 1977

Description: During the past quarter significant progress was made toward demonstrating the feasibility of producing protein and methane from pulp mill waste materials. The most significant result obtained in the project to date occurred when ozonated spent sulfite liquor, SSL, was demonstrated to be a suitable substrate for biosynthesis. Sustained production of methane was obtained by biological conversion of ozonated SSL. Total methane production approximated 2 volumes of gas per volume of ozonated SSL af… more

Non-Process Element (NPE) Removal Using Functionalized Monolayers on Mesoporous Supports

Description: As Kraft pulp mills move toward minimum impact manufacturing, one of the most difficult challenges is the development of strategies for dealing effectively with buildup, carryover, and recovery of cationic and anionic non-process elements (NPEs). Even at low concentrations, NPEs present a serious concern due to scaling and other reactions caused by Ca, Mg, Mn, Fe, Cu, phosphates, silicates, and aluminates. The drivers behind NPE removal include environmental regulatory issues (e.g., Mn), scale … more

Measures to reduce industrial consumption of petroleum under a short-term energy emergency

Description: Significant opportunities for petroleum conservation in the industrial sector in the event of an energy emergency are discussed. The most feasible government options identified are presented. These and the probable savings are: removing institutional barriers to fuel switching in industrial boilers and burners (384 to 407 Mbbl/day); rescinding certain air pollution regulations (19 to 100 Mbbl/day); restricting export of energy-intensive goods (20 to 60 Mbbl/day); rescinding thermal pollution re… more

Biomass energy success stories: a portfolio illustrating current economic uses of renewable biomass energy

Description: This second edition of the Biomass Energy Success Stories covers a wide range of examples of organizations which have experienced economic benefits by substituting renewable biomass energy for non-renewable fossil fuels. In addition to the broader spectrum of industry seen to be pursuing this approach, the cases illustrate a move towards innovative and technologically more sophisticated approaches. For example, the Quebec Community's thermal accumulator acts as a buffer to accommodate the varia… more

Evaluation and Development of a Prototype Electrokinetic Sonic Amplitude (ESA) System for On-Line Measurement of Charge in Papermaking Process Streams

Description: The papermaking industry uses an abundance of chemicals to control the process of papermaking. These chemicals are used to control everything from paper strength to brightness. Due to the natural variability of products used in papermaking, the chemistry of the process is heavily monitored. Cationic (charge) demand is one of the most important parameters in process control of papermaking. High variations in cationic demand result in off-spec final product or paper breaks resulting in wasted pro… more

Energy use in Poland, 1970--1991: Sectoral analysis and international comparison

Description: This report provides an analysis of how and why energy use has changed in Poland since the 1970s, with particular emphasis on changes since the country began its transition from a centrally planned to a market economy in 1989. The most important factors behind the large decline in Polish energy use in 1990 were a sharp fall in industrial output and a huge drop in residential coal use driven by higher prices. The structural shift away from heavy industry was slight. Key factors that worked to in… more

Boiler Blowdown Heat Recovery Project Reduces Steam System Energy Losses at Augusta Newsprint

Description: The boiler blowdown process involves the periodic or continuous removal of water from a boiler to remove accumulated dissolved solids and/or sludges. During the process, water is discharged from the boiler to avoid the negative impacts of dissolved solids or impurities on boiler efficiency and maintenance. However, boiler blowdown wastes energy because the blown down liquid is at about the same temperature as the steam produced. Much of this heat can be recovered by routing the blown down liqui… more

Development of a novel and environmentally friendly method for the separation of non-inked and inked cellulose fibers in wastepaper

Description: There is currently no method in existence for the separation of non-inked cellulose fibers from the inked fibers in old newsprint (ONP). Current methods for de-inking involve the pulping of the whole paper in the presence of chemicals (caustic sodium hydroxide, diethylenetriaminepentaacetic acid, sodium silicate, hydrogen peroxide, and a surfactant) followed by washing and flotation operations. The result is a mixture of high- and low-quality de-inked secondary fibers and the production of wast… more

Proof of concept test and evaluation (pilot/mill testing) of Lasentec refining sensor. Final report

Description: On-line measurement of refining development is of vital concern to the papermaker since its control directly affects the uniformity of the product, drainage, drying and energy consumption. The current methods of monitoring fiber development during refining rely on secondary measures such as: Drainage rate, either measured off-line as Canadian standard freeness, or on-line with a number of commercial sample and test devices; energy consumption at the refiner; or changes in vacuum on the paper ma… more
