Abstract
Minyak bumi merupakan sumber energi utama sekaligus bahan
pokok yang dibutuhkan oleh manusia di dunia. Minyak yang
dipompa ke atas dari dalam bumi bukan merupakan minyak yang
murni langsung, melainkan minyak yang bercampur gas dan juga air
bersama dengan kandungan-kandungan senyawa kimia yang
mengandung hidro dan karbon. Separator diperlukan untuk
memisahkan fluida hydrocarbon menjadi tiga fase pemisahan yaitu
minyak, air dan gas. Dalam rancang bangun separator tiga fasa ini,
sistem flow monitoring penting adanya guna mengetahui nilai debit
atau laju aliran yang melalui inlet separator sehingga lebih
memudahkan manusia dalam mengamati proses separasi. Nilai
pengukuran laju aliran dapat diamati melalui tampilan LCD
menggunakan controller ATmega8535 dengan sensor water flow dan
data nilai laju aliran dimonitoring dan disimpan melalui Visual
Studio. Monitoring flow digunakan untuk mengetahui laju aliran
yang akan memasuki separator. Laju aliran akan dipengaruhi oleh
tekanan yang dihasilkan oleh booster pump. Pembacaan nilai laju
aliran sebelum memasuki separator horizontal 3 fasa relatif tetap
(stabil) yaitu berada di sekitar 15 L/menit. G1” water flow sensor
yang digunakan dapat memberikan hasil pengukuran yang linier
dengan spesifikasi nilai standar deviasi sebesar 1,122 L/menit, error
sebesar 7,07%, Uexpand sebesar 0,707 L/menit, nilai akurasi
pembacaan sensor sebesar 99,08% dan nilai presisi dari sensor
sebesar 99,09%
============================================================================================
Crude oil is the main energy source once a staples needed by
humans in the world. The oil is pumped to the top of the earth is not
a pure oil directly, but oil is mixed with gas and also water along
with the contents of chemical compounds containing hydro and
carbon. The required separator for separating hydrocarbon fluids
into three phases separation, namely oil, water and gas. In the
design build of this three-phase separator, flow monitoring system is
important to determine the value of the flow rate through the inlet
separator so that it easier for humans to observe the separation
process. Flow rate measurement values can be observed through the
LCD display using the controller ATmega8535 with water flow
sensor and flow rate value data to be monitored and stored via
Visual Studio. Monitoring flow is used to determine the flow rate that
will be entering the separator. The flow rate will be influenced by the
pressure generated by the booster pump. The reading of the flow rate
value before entering the horizontal three phase separator is
relatively fixed (stable) which the amount around 15 L/minute. G1"
water flow sensors are used provide linear measurement results with
the specification value of a standard deviation is 1.122 L/minute,
error of 7.07%, Uexpand amounted to 0.707 L/minute, sensor reading
accuracy value of 99.08% and a precision value of sensor at
99.09%
