Abstract

The objective of this study is to propose a solution for process plant upgradation becoming extinct due to obsoleteness of spares. The study will help in reliability, availability, and maintainability (RAM) based upgradation of control system of process plants in developing countries. Available options for plant upgradation are compact control, modular, and semiautomatic. RAM based upgradation provides solution which is high in reliability and availability (usually all parts are replaced with upgraded and compatible technology) and is easy to maintain throughout the service life of process plant. Case study for stacker and reclaimer of cement plant upgradation is considered to both implement and evaluate the idea. Upgradation methodology is finalized by expert’s feedback regarding selection of hardware with respect to availability, market survey to validate the opinion, and economical availability viability of selected hardware. Pre- and postupgradation scenarios are analyzed to validate the implementation of study and conclude the expected outcomes. The process plant upgradation yielded a cost-effective solution to the problem with automation increasing by 17%, plant maintainability increasing by 80%, and downtime of plant decreasing by 17%. Among all available options, modular design Op1 is considered the best choice that can satisfy RAM criteria.

采用可靠性、可用性和可维护性（RAM）标准的工艺装置升级

本研究的目的是提出一种解决方案，以解决因备件过时而导致的工艺装置升级。该研究将有助于发展中国家工艺装置控制系统的可靠性、可用性和可维护性(RAM)升级。工厂升级的可用选项是紧凑型控制，模块化和半自动。基于RAM的升级提供了高可靠性和可用性的解决方案(通常所有部件都替换为升级和兼容的技术)，并且在过程装置的整个使用寿命中易于维护。以水泥厂改造中的堆料机和回收机为例，对该思想进行了实施和评价。升级方法是通过专家对硬件选择的反馈来确定的，这些反馈涉及到可用性、验证意见的市场调查以及所选硬件的经济可行性。分析了升级前和升级后的场景，以验证研究的实施，并得出预期结果。过程工厂升级产生了一个经济有效的解决方案，自动化程度提高了17%，工厂可维护性提高了80%，工厂停机时间减少了17%。在所有可选方案中，模块化设计Op1被认为是满足RAM标准的最佳选择。
