Abstract

Telah dibuat sebuah rancang bangun sistem pengendalian suhu pada condenser plant fluidized bed reactor pengolahan oil sludge dengan menggunakan sensor termokopel tipe k, pengkondisian sinyal MAX6675, motor servo MG996R sebagai aktuator, mikrokontroler Atmega 32. Hasil pengukuran ditampilkan dengan menggunakan LCD 16x2 dan software Visual Studio 2015. Pengendalian suhu pada condenser ini perlu dilakukan agar perpindahan panas antar uap minyak dan air pendingin dapat berlangsung secara efisien. Aktuator yang dikendalikan adalah posisi bukaan valve yang digerakkan oleh servo untuk mengatur debit air pendingin yang akan dialirkan pada ruang annulus sehingga suhu steam pada tube condenser terjaga suhunya sesuai dengan set point yang telah ditentukan dan uap minyak dapat terkondensasi menjadi kondensat yaitu minyak mentah. Sensor yang digunakan telah dilakukan uji sensor dengan pembanding alat standard Rotronic HygroPalm. Berdasarkan uji sensor tersebut didapatkan hasil kalibrasi dengan nilai ketidakpastian sebesar ± 1,5358 dengan tingkat kepercayaan 87,7%. Respon sistem pengendalian suhu pada condenser ini pada setpoint 70⁰C memiliki settling time sebesar 1 menit 30 detik, maksimum overshoot 0,78⁰C dan error steady state rata-rata 0,459⁰C. ======================================================================================== A temperature control system design has been developed in condenser plant fluidized bed reactor oil sludge processing using k type thermocouple sensor, MAX6675 signal conditioning, MG996R servo motor as actuator, Atmega 32 microcontroller. The measurement result is displayed using 16x2 LCD and Visual Studio 2015 The temperature control of the condenser is necessary so that the heat transfer between the steam of oil and cooling water can proceed efficiently. The controlled actuator is the servo-driven valve opening position to adjust the cooling water discharge to be drained in the annulus chamber so that the steam temperature of the condenser tube is maintained at a set point and oil vapor can condense to a crude oil condensate. Sensors used have been tested with the standard sensor sensor Rotronic HygroPalm. Based on the sensor test obtained calibration results with an uncertainty value of ± 1.5358 with a trust level of 87.7%. Response of temperature control system at this condenser at setpoint 70⁰C has settling time 1 minute 30 seconds, maximum overshoot 0,78⁰C and error steady state average 0.459⁰C.
