MENINGKATKAN KUALITAS REPEATABILITY DAN REPRODUCIBILITY SAMPEL LIQUID GAS DE-ETHANIZER DI PT. BADAK DENGAN MEMODIFIKASI ALAT PREPARASI PADA KROMATOGRAFI GAS
Abstrak: Modification has been
done to the gas chromatograph by adding a de-ethanizer preparation tool that
serves as the evaporation of liquid samples de-ethanizer gas from the LNG
(Liquid Natural Gas) plant PT. Badak NGL Bontang, East Kalimantan. With the aim
to obtain stable analysis results as required. From the results obtained for
the repeatability value 0.104% methane component, 0.036% ethane component and
0.154% propane components and reproducibility values obtained for the methane
component of 0.025%, 0.036% component ethane, and propane components 0.014%.
Data analysis of the samples obtained test results are still below thelimit
allowed by the method of GPA 2261-64 which found samples with good homogeneity
so that the analysis becomes stable and the true value can be resposibility and
laboratory as a Quality Control can keep reliability for LNG Plant.
