ANALISA KADAR SILIKA PADA AIR UMPAN KETEL DAN AIR BOILER DENGAN ALAT LOVIBOND DI PKS PT.
PERKEBUNAN NUSANTARA IV DOLOK ILIR
ABSTRAK
Analisa kadar silika telah dilakukan pada air umpan ketel dan air boiler di PKS PT. Perkebunan Nusantara IV Dolok Ilir. Sampel air umpan ketel diambil
dari tangki yang telah dipanaskan sedangkan sampel air boiler diambil dari drum pipa pemanas pada boiler. Kandungan silika didalam sampel ditentukan secara komparasi dengan pereaksi Amonium molybdat, HCL 1:1, dan asam oksalat.
Penentuan dilakukan selama periode 18-27 Februari 2015. Hasil yang diperoleh menunjukkan bahwa kandungan silika dari air umpan ketel adalah 4,1 ppm
sedangkan air boiler adalah 141,6 ppm. Maka dapat disimpulkan bahwa hasil yang telah diperoleh telah memenuhi standart PKS PT. Perkebunan Nusantara IV Dolok Ilir.
ANALYSIS VALUE OF SILICA IN BOILER WATER AND CATTLE WATER WITH LOVIBOND IN PKS PT.
PERKEBUNAN NUSANTARA IV DOLOK ILIR
ABSTRACT
Analysis was performed on a silica content of boiler feed water and boiler water at the PKS PT. PTPN IV Dolok Ilir. Samples taken from the boiler feed
water tank heated while the boiler water sample taken from the heating pipes in the boiler drum. Silica content in the sample is determined by comparison with a
reagent Ammonium molybdat, HCL 1: 1, and oxalic acid. The determinations were performed over a period of 18 to 27 February 2015. The results showed that the silica content of boiler feed water is 4.1 ppm while the water boiler was 141.6
ppm. It can be concluded that the results that have been obtained already meet the standard PKS PT. PTPN IV Dolok Ilir.
