BEHAVIOURAL ANALYSIS OF AGRO-BASED INDUSTRY: PRILLING SYSTEM OF UREA PRODUCTION IN FERTILIZER PLANT

ABSTRACT

In this paper a subsystem of a Fertilizer plant is analyzed using reliability theory. we are discussing about the Prilling subsystem of urea production process which comprises three subsystems. The key parameters of the system i.e. the Mean Time to System Failure(MTSF), Availability, Busy period of Server, number of Server’s visits and number of Replacement etc. (under steady state conditions), are evaluated using the Regenerative Point Graphical Technique(RPGT). The study can be extended for multiple unit system having Perfect and Imperfect Switch-Over devices. The Regenerative-Point Graphical Technique is useful for the evaluation of the parameters in a simple way, without writing any state equations and without doing any lengthy and cumbersome calculations.
