Reliability Analysis and Engineering Application on Chemical Process Equipment System

Reliability and availability are important symbols which weigh the reliability of product. Chemical production equipment system is consisted of many single devices. Due to special dangerous, the reliability analysis to whole equipment system is very important to keeping the safety of production process. In this article, to chemical process equipment system, the reliability calculation method, basic principles, basic assumptions and calculation program are described. To a aromatic semi-renewable dehydration process system, by using the reliability calculated method above, the fault tree and reliability block diagram are derived, the system reliability and availability are accounted, the corresponding reliability and availability curves are obtained and the main factors influencing the reliability of the system are analyzed.

Abstract Tantalum finds its largest use in the electronics industry, where it is used in filaments, filament supports, and capacitors. Metallurgical grade tantalum is used extensively in chemical process equipment. Tantalum resists corrosion by body fluids and is used in prosthetic devices. Its high melting point gives it utility in vacuum furnace components. It is also used as an alloying element in superalloys. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Ta-11. Producer or source: Cabot Corporation.

The hazard of chemical process equipment consists of two parts: the inherent hazard of process equipment and the hazard from domino effect among equipments. The inherent hazard of equipment depends on the properties of the substance present in the equipment and the specific process conditions. The domino effect is responsibility for many most destructive accidents in the chemical process industry. However, domino effect is either not considered at all or is done with much less rigour than is warranted. A method was proposed to evaluate the hazard of chemical process equipment. The inherent hazard and the hazard from domino effect were considered in the method. The procedure for the domino effect analysis among equipments was presented to evaluate the hazard from the domino effect. The method was implemented in a case study. The results show that it can be used to select the process equipment which should be intensive monitored.
