Das Zusammenwirken Technischer Regeln und technischer Entwicklungen für die Sicherheit von Chemieanlagen

Interplay of technical specifications and technical developments in the safety of chemical plant. In the planning, construction, and operation of chemical plant requiring close supervision the aims are defined by rules and regulations which refer back to a comprehensive compilation of technical specifications concerning the means by which these aims can be accomplished. These rules were, and are, worked out by business federations in collaboration with occupational and governmental agencies in joint committees. Since both practical experience and fresh knowledge resulting from technical developments are gained in industrial undertakings, the feedback of experience from industry ensuring continuous up-dating of the technical specifications is of immense importance. Starting from the current state of the art, the expert frequently has to work out solutions to specific problems. Once general conclusions which have proved their value in practice can be derived, they are incorporated in the technical specifications. Such a contribution to safety engineering is illustrated for a pressure vessel. The examples described range from the derivation of reliable criteria for assessing the danger of brittle fracture of high-strength steel pressure vessels to the development of preventative techniques of nondestructive testing of components. They also incorporate the development of design data for conservative dimensioning of safety valves for frothing mixtures and their safe release into the atmosphere as well as investigation of the pressures expected on explosion of flammable hydrocarbon/air mixtures.     

FWRP压力容器的可靠性设计研究

纤维缠绕聚合物基复合材料(FWRP)压力容器在航空航天及民用领域的应用是当前研究热点。减轻结构重量对于性能和成本都具有非常重要意义。为实现FWRP压力容器结构设计和安全评定的高目标,引入可靠性理论,应用统计学原理,基于应力-强度干涉模型,以同一失效概率为标准进行FWRP压力容器结构设计,以取代现应用的传统安全系数法设计。采用无碱无捻玻璃纤维-环氧树脂材料体系,应用同一缠绕工艺制备8个压力容器。试验得到纤维强度、缠绕角、几何尺寸、爆破压力等随机变量特征值。其结构可靠性设计值(纤维缠绕壁厚)与试验结果基本吻合,并显著小于常规设计值。将各设计变量随机分布特征值与压力容器结构设计相结合,实现安全与经济的有效统一,为可靠性设计在FWRP压力容器上的应用与发展提供了依据。

Applying Spray Drying to Customized Powder Manufacture

Spray drying is an important continuous industrial process for drying pumpable liquid formulations irrespective of their heat sensitivity, rheology, solids content and processing rate. Furthermore spray drying has the capability through drying chamber design, plant layout and mode of operation to produce dried products of specific particulate size and morphology. These are important aspects when spray drying technology is applied to the needs of customized powder manufacture. There are many examples in industry where spray dried powders have to meet stringent specifications set by such factors as end-product powder quality standards dictated by global competition, dry raw material characteristics required for optimum downstream processing, and dry materials handling to comply with environmental, health and safety issues. Spray drying is no longer regarded just as a convective industrial drying concept, but also as an integral part of modern manufacturing practices applying powder technology. This paper r
