Quantitative Risk Assessments (QRAs) are done if dangerous substances are thought to be present at a location (e.g. industrial sites and transportation routes) in amounts that can endanger the environment. Risk assessment studies essentially encompass; x Hazard identification using techniques like checklist, preliminary hazard analysis, what-if, and HAZOP. x Hazard analysis using techniques like fault tree analysis, event tree analysis and dispersion modeling. x Consequence analysis using relevant models like ALOHA & PHAST. x Mitigation measures including: ¾ Risk reduction ¾ Emergency preparedness – on-site as well as off-site 7.3.1 Risk Assessment Methodology A typical risk assessment process consists of following tasks: x Obtaining detailed description of process and plant x Identification of hazards x Identification of vulnerable targets x Select Most Credible Scenario which can be converted into an accident out of several major and minor. x Select Worst Case Scenario which has the highest potential to cause an accident of maximum damage x Identification of mitigating measures x Estimation of consequences - in the plant in form of fire, explosion and toxic effects x Estimation of frequency of occurrence x Estimate Effect of Damage x Decision making 7.4 Hazard Identification and Risk Assessment (HIRA) The hazard identification and risk assessment is used to identify possible accidents and estimate their frequency and consequences. While identifying hazards only those areas of plants having potential risk are used further for risk analysis. Hazard is considered as characteristic of system/plant/process that presents potential of causing harm to people, property and the environment. Hence, all the components of a system/plant/process are thoroughly examined to assess their potential for initiating or propagating an unplanned event/sequence of events, which can be termed as an accident. 7.4.1 Hazard Identification Methods Hazard identification method used for the proposed project is given below. x Identification of major hazardous units based on Manufacture, Storage and Import of Hazardous Chemicals Rules, 1989 of Government of India (as amended in 2000); x Hazard Indices: Identification of hazardous units and segments of plants and storage units based on relative ranking technique.

    PEER-REVIEWED ARTICLE bioresources.com Effect of Alkyl Ketene Dimer on the Physical, Mechanical, and Biological Durability of Plywood Gaye Köse Demirel,a Halime Güdül,b Ali Temiz,a,* Süleyman Kuştaş,a and İsmail Aydın a The effect of alkyl ketene dimer (AKD) on plywood properties was studied. AKD is widely used in the paper industry as a sizing agent and can esterify wood cell wall components. Two types of veneers obtained from alder (Alnus glutinosa subsp. barbata (C. A. Mey) Yalt.) and beech (Fagus orientalis L.) wood logs were used. Two different treatment processes and two different concentrations (1% and 3%) of AKD were tested. The first method was AKD-dispersion, which was mixed with glue and sprayed onto veneers. The second method was dipping veneers into the AKD solutions (1% and 3%) for 25 min. Water uptake after 2 h, 24 h, and 48 h was reduced by the AKD treatment. Plywood produced from AKD impregnated veneers showed the lowest thickness swelling versus untreated plywood and plywood produced from AKD blended in glue. The AKD treatment generally reduced the mechanical properties of the plywood. However, AKD treatment considerably improved the biological resistance against brown rot fungi (Coniophera puteana BAM Ebw. 15) and white rot fungi (Trametes versicolor CTB 863A). Increased methyl/methylene and carbonyl groups of the alkyl chain were determined in the Fourier transform infrared (FTIR) spectra of specimens subjected to the AKD- dispersion method.

ABSTRACT The influence of shear, electrolytes, polyelectrolytes (anionic trash), and surfactants on the colloidal stability of differently formulated AKD dispersions was investigated. The stability was tested under shear in a Britt Dynamic Drainage Jar by measuring particle size distributions and microelectrophoretic mobilities. Three cationic dispersions were used, stabilised with (1) starch with low charge density, (2) starch with medium charge density and a polyaluminum salt, (3) synthetic polymer with high charge density. All dispersions showed good to excellent stability to high levels of shear and electrolytes. All tested dispersions were influenced by carboxymethylcel- 12th Fundamental Research Symposium, Oxford, September 2001 393 R. Mattsson, J. Sterte and L.

Western Michigan University Kalamazoo, Michigan April, 198'.l ABSTRACT It is the purpose of this thesis to attempt to eval­ uate the influence of fines on an alkyl ketene dimer (AKO) synthetic sizing agent and to study the role of fines on sizing. It was found that the addition of fines lowered the degree of sizing in the sheet. Since there was more surface area available when fines were increased, more sizing agent was necessary in order to obtain the same level of sizing with a Hercules or Cobb Size Test.

Eveliina Jutila Date 16.4.2014 Number of pages Language English 184+17 Abstract Paperfluidic devices are microfluidic devices patterned out of paper or other highly porous material. Liq- uid transport in paperfluidic devices is propelled either by surface wetting or interior capillary wicking. The direction of aqueous liquid flow on such devices is controlled by selective patterning of hydrophobic barriers on an otherwise hydrophilic base substrate. A variety of hydrophobic materials and printing methods have been lately demonstrated as feasible for producing such patterns. Unlike conventional graphic printing, hydrophobising ink has to penetrate the whole depth of the wicking substrate, in order to produce properly functioning leak-free barriers. One major expected application area for paperfluidics in the future is in the field of lab-on-a-chip devices, intended to provide simple, transportable, disposable and self-sufficient analysis tools for medical diag- nostics and environmental monitoring. On such devices, fluid samples flow along hydrophilic channels through assay zones, where they chemically interact with pre-applied reagents.

  • Dialkylketones in Paperboard Food Contact Materials—Method of Analysis in Fatty Foods and Comparative Migration Into Liquid Simulants Versus Foodstuffs
    molecules Article Dialkylketones in Paperboard Food Contact Materials—Method of Analysis in Fatty Foods and Comparative Migration into Liquid Simulants Versus Foodstuffs Antía Lestido-Cardama 1,* , Ángela Störmer 2 and Roland Franz 2 1 Department of Analytical Chemistry, Nutrition and Food Science, Faculty of Pharmacy, University of Santiago de Compostela, 15782 Santiago de Compostela, Spain 2 Fraunhofer Institute for Process Engineering and Packaging (IVV), Giggenhauser Straβe 35, 85354 Freising, Germany; [email protected] (Á.S.); [email protected] (R.F.) * Correspondence: [email protected] Academic Editor: Mihai Brebu Received: 31 January 2020; Accepted: 15 February 2020; Published: 18 February 2020 Abstract: Dialkyl diketene dimers are used as sizing agents in the manufacture of paper and board for food contact applications to increase wetting stability. Unbound residues can hydrolyze and decarboxylate into dialkylketones. These non-intentionally added substances (NIAS) have potential to migrate to fatty foods in contact with those packaging materials. In Germany, the Federal Institute for Risk Assessment (BfR) established a specific migration limit (SML) of 5 mg/kg for the transfer of these dialkylketones into foodstuffs. In order to investigate the differences between simulants and real foods, an analytical method was optimized for extraction and quantification of dialkylketones in edible oils and fatty foods by gas chromatography coupled with flame ionization detection (GC-FID), and additionally by gas chromatography with mass spectrometry (GC-MS), to confirm their identification and to quantify them in case of interferences. Dialkylketones are separated from the extracted fat by alkaline saponification of the triglycerides. Dialkylketones migration from paper-based food contact articles into organic solvents isooctane and dichloromethane, in olive and sunflower oils, and in fatty foods (croissants, Gouda, cheddar cheese, and salami was studied).
