In 2008, Alpha Natural Resources initiated investigations to determine the most desirable technology to facilitate the continuation of fine tailings disposal and water management at the Trace Branch tailings impoundment site during the capping stage at the Rockspring coal preparation plant. This 1800 ton per hour thermal coal facility was nearing capacity of its existing tailings impoundment and needed to determine and evaluate alternative methods to increase impoundment capacity and improve water management. This paper discusses the findings of various assessments and trade off studies that resulted in a decision to install eight three-meter belt presses capable of dewatering 180 tons per hour of tailings solids in a slurry so they could be mixed with coarse material and used as capping material.

Filtrate drainage during mat formation in a brownstock washer directly affects the washer's productivity and indirectly affects its efficiency. In this paper, we demonstrate the role of entrained air on mat formation and filtration as they occur in brownstock washing. We further show how chemical treatments, such as defoamers and wash aids, and fiber surface chemistry influence air entrainment and thereby washer productivity and efficiency. Application: With this knowledge, washer operations can be improved through the design and selection of better treatments.

The dynamic rheological properties of a model poly(acrylic acid) microgel mucilage in the close-packed concentrated region (reduced concentration cQ > 1) were evaluated as a function of the degree of neutralization, α = [NaOH]/[COOH]. As the parent microgel is neutralized, up to an order of magnitude increase is observed in the swelling ratio Q, dynamic modulus, and yield properties. Four regions were observed where the dynamic rheological properties exhibited a different power law dependence with increasing α. The dynamic yield strain does not change remarkably with increased neutralization, whereas the dynamic yield stress increases more than 10-fold. This supports a mechanism where the yield strain depends on geometric considerations, whereas the yield stress reflects the stress required to force microgels past adjacent microgels. A linearity observed between modulus and dynamic yield stress with increased neutralization suggests a concerted expansion and affect on the rheological properties with the microgel core and emanating polymer chains.

This paper discusses a technology that was developed by Ashland and which has been utilized for several years to provide excellent MB control in paper machines. Recently, the same technology was adapted for cooling tower MB control with excellent success. The technology is based on the use of a biocide of lower oxidizing potential when compared to the more common ones like hypochlorite, chlorine dioxide and chlorine gas. The active oxidizer is bromine-activated chloramines (BAC) and it is safely generated on site, by reaction between 2 common products. BAC chemistry provides significant advantages compared to other oxidizers. Because BAC is a less aggressive oxidizer, MB control is obtained at a lower oxidation-reduction potential (ORP) level when compared to chlorine, for example. This facilitates better corrosion rates because corrosion inhibitors are not impaired by high ORP. Another significant advantage is the ability of BAC to selectively attack the MB growth, and not be consumed by organic matter or any other components that easily react with strong oxidizers. Results from 3 case histories will be discussed. In addition to excellent MB control other benefits such as lower corrosion rates, cleanliness, less sludge and fewer shutdowns will be demonstrated. © 2013, Assoc.

A new approach to developing strength in recycled tissue and towel grades using a cellulase enzyme-based product is yielding beneficial results. The use of cellulases to develop strength in virgin fiber is well documented; however, its effectiveness in recycled papers has proven to be more challenging. Recycled tissue manufacturers know that strength, drainage and downtime issues are common when using this type of furnish. This is mainly due to the presence of lower quality fibers in recycled furnish that are not only shortened but also contaminated with stickies, which lowers the overall fiber reactivity. This latest product development combines a proprietary base enzyme with a functional polymeric additive that controls contamination downstream and allows better access of the enzyme to the fiber surface for fibrillation. This new cellulase-based product, which is marketed by Ashland as Hercobond ™ 8800 paper performance additive (Product A), has proven to be more effective than older cellulase-based products and chemical strength additives. The enzyme product further addresses a concern related to the negative effect on fiber yield. It also overcomes the negative attributes of older cellulase-based products when cellulase is overdosed or has a prolonged contact time with wood fiber. This paper demonstrates the synergistic effects of the new product formulation on enzyme activity and discusses the strength and stickies control benefits provided. Mill trial data is presented to highlight the applications of the new product in recycled tissue manufacturing.

Tissue softness is a property that all manufacturers attempt to control, either to produce the highest quality tissue or to produce a level of softness at a specific cost. Softness can be enhanced by changing the furnish used or by changing the tissue machine operation. Alternatively, sheet softness can also be enhanced downstream of the tissue machine using treatments applied to the surface of the sheet. Choosing the most cost effective approach for achieving the desired level of softness is complicated by the problem of quantifying the improvement in softness. Panel testing is the method most commonly used to evaluate softness; however, this method generally only provides a qualitative result. Ashland Water Technologies is currently developing a quantitative method for evaluating softness and correlating softness changes with fundamental sheet properties. The goal of this effort is to provide a tool for choosing the most appropriate method for enhancing softness. This paper first discusses the differences between low, medium and high quality tissues; the discussion includes data quantifying differences in sheet properties. Next, the outline of a softness model that correlates fundamental sheet properties with softness is presented. An example implementation of the model is developed. Finally, selected results from a study on the effectiveness of surface treatments for enhancing softness are presented; the data presented quantifies the softness improvement and relates it to potential model parameters.

Many paper machine efficiency problems originate in the press section and are caused by high open draw and press roll picking. High open draw and press roll picking often result in poor sheet release, sheet breaks and quality issues such as dirt and holes in the sheet. Due to these issues, press rolls are often the number one speed-limiting factor on high-speed paper machines. Ashland recently developed a new generation of roll release products that improve the runnability of high-speed paper machines. These roll release products, which are marketed as Presstige™ roll cleaning and conditioning agents, prevent deposits such as pitch and stickies from adhering to roll surfaces. In contrast to older technologies, application of these new products to press rolls leads to a significant reduction in adhesion of the wet paper web to the roll surface and to significant reductions in the draw or speed differential between the last press roll and the first dryer section. This ultimately results in a significant reduction in web breaks. The new formulations are effective on ceramic, granite and composite surfaces and are applied using conventional doctor blade lubrication showers. This paper reviews the development of the new roll release products using both a wet web peel tester and the fundamental work of adhesion calculations. Results from several commercial validation trials are also described.
