Biomass-derived coal or “biocoal” produced using a torrefaction process presents a carbon-neutral option of coal for power generation. While torrefaction delivers a carbon content and hydrophobicity comparable to coal, it lowers its density and creates material handling, storage, and transportation challenges. Densification into briquettes would help mitigate these challenges. However, the torrefied biomass is difficult to densify and may require the use of binders, which are expensive and can be incompatible with respect to material and emissions. A cost-effective approach to utilize lignin in-situ of the biomass to promote binding during densification was demonstrated using a pilot-scale briquetter unit during this study. Lignin, a cross-linked polymer, tends to break down and lose its binding ability under high-temperature conditions of torrefaction. In this paper, we investigated the use of a lightly torrefied material as a binder―LTM (biomass torrefied in the transition region of non-reactive and reactive temperature ranges of torrefaction). When mixed with torrefied biomass and densified together under suitable moisture and temperature conditions, the lignin is shown to mobilize and provide binding to the briquettes. The results showed that briquettes produced using LTM as binder and 10% to 11% moisture provided in-situ binding, improved density and durability, and produced hydrophobic briquettes.

Pet Films

Low-reflection polyethylene terephthalate (PET) films are fabricated with nano-imprinting method. The films are then used to cover polycrystalline silicon solar cells. The morphological and optical properties of films are investigated. The films have periodic cylinder-like nanostructures and relatively low reflectivity in light incident angle ranging from 30[Formula: see text] to 60[Formula: see text]. The nanostructures are with a period of 600 nm and height of 90 nm. Besides, the polycrystalline Si solar cells covered with the films exhibit 12% more power generation than the cells covered with glass. Nano-imprinting method offers a cost-effective approach to fabricate omnidirectional anti-reflection films, which could boost the power generation of Si solar cells. Additionally, the films also have potential applications in different types of solar cells due to its facile fabricating process.

Detection And Localization

The partial discharge (PD) phenomenon is very harmful for electrical appliances and its early detection could be a cost effective approach for the industry. Although many techniques are used for PD detection yet no technique has presented widely acceptable solution. Still the subject needs parallel study of the detection techniques. In this study, partial discharge signal has been captured by the three techniques using fiber optic sensor (FOS), Piezoelectric Sensor (PZT), leakage current (LC) techniques. In these experiments, FOS shows good sensitivity in the range of applied high voltage > 5 kV. The sensitivity and noise level of PD signal was different in these two experiments. The location of a PD was demonstrated in a 500 gallon water tank using convolution method.

Queensland coal seam gas (CSG) company Arrow Energy (Arrow) has implemented a safer, more efficient and cost effective approach to the transportation and supply of well materials to site. This paper examines Arrow’s approach to mitigating the transportation risks. It looks at current transport health, safety and environment (HSE) challenges, approach to address these risks, outcomes and future opportunities. The movement of well materials has been a concern for Arrow; it is a repetitive activity because wells are drilled, completed and worked over on a regular basis. Arrow’s challenge was to determine a better and safer way to load, unload and transport these materials. To address this material handling risk, an Arrow team developed a specially modified 40-foot flat rack (FR) capable of safely and securely holding a variety of materials. The FR can be picked up by a side-loader truck (swing-lifter), thereby enabling autonomous and safe loading and unloading. Warehouse staff can pre-pack all materials, thereby saving significant time for loading and unloading. Time and resources are also saved at the rig site where the FR can be unloaded autonomously. This unique design reduces human interaction and improves HSE personal safety risk significantly. A continuous improvement approach to further enhance the FR design to achieve better efficiency and safety for staff, as well as expanding its use to other business areas, is a key priority to Arrow.
