Abstract
In propylene products, there is still a small proportion of propane which still the impurity of the propylene. Therefore, a tool for monitoring is needed while controlling the content of impurities (propane) so that the propane content in propylene is within the permissible tolerance, a maximum of 0.4 vol%. The tool that can be used to analyze the propane content in propylene is the Online Propane Analyzer which works continuously for 24 hours. Need to installation of the Online Propane Analyzer. However, the installed propane analyzer often fails (downtime) caused by the inability of the oven (heater) to maintain the temperatures stability in the column at a temperature of 60 °C, so that the column is unable to separate the propylene components mixed with propane properly. Frequent down time on the analyzer causes the installed propane analyzer to be poor and unreliable. The value of reliability tests with existing data is only 60.51%, under the IEEE 1336-2000 standard. it is important to do a retrofit analyzer to improve the analyzers performance in maintaining the quality of propylene according to the design, to facilitate the operator in monitoring the process and to facilitate technicians in performing preventive maintenance.
