Design and Development Aspects of Process Instrumentation for a Newly Developed Technology
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 9
Abstract
Process development is a multidisciplinary field involving experts from various branches of engineering such as chemical, instrumentation, mechanical, electrical and electronics engineering. The role of an instrumentation engineer increases as we move from bench level project to a pilot scale level, and then to a commercial scale level. To design a process and its control effectively, it is necessary to understand the process thoroughly. The main role of an instrumentation engineer involves design, commissioning and maintenance of the instruments and also control of the processes. This paper is based on the authors experience in the design of such systems. The detailed description about the role of an instrumentation engineer in the development of a process and the steps involved in the designing of a chemical process is explained. The general rules to be followed while designing a process are explained in detail with reference to a vacuum distillation process. The design considerations in the vacuum distillation process, control loops and basic instrumentation applied for the equipment and the process lines are explained. These designs and data sheets are used for commissioning and automation of the process plant. Using these data sheets, one can determine the type of instrument to be used for measuring a particular physical parameter, number of instruments required, alarms and interlocks used in the plant and to easily locate any instrument during the maintenance of the plant.
