Sumur IBN-2 merupakan sumur eksplorasi di Lapangan Panas Bumi Dieng
yaing ditinggalkan dianggap tidak produktif dikarenakan temperatur sumur yang
didapat kecil. Sumur yang gagal tidak dapat dimanfaatkan kembali dengan cara
konvensional. Sehingga dilakukan perencanaan binary cycle untuk memanfaatkan
sumur IBN-2 yang memiliki potensi rendah.
Perencanaan binary cycle, hal yang pertama dilakukan adalah pengambilan
data sumur IBN-2 untuk mengetahui tekanan (P), temperatur (T), dan laju alir
massa (m) fluida pemanas dari kepala sumur hingga outlet heat exchanger.
Selanjutnya, menghitung ∆T fluida pemanas pada inlet dain outlet heat exchanger
untuk menentukan fluida kerja yang digunakan dalam siklus binary cycle ini.
Setelah itu, memilih fluida kerja untuk mengetahui tekanan (P), temperatur (T), laju
alir massa (m), entalpi (h), dan entropi (s) fluida kerja di outlet feed pump, inlet heat
exchanger, outlet heat exchanger, inlet turbin, outlet turbin, inlet kondensor, outlet
kondensor, dan inlet feed pump. Menghitung besarnya entalpi di dalam turbin untuk
mengetahui energi listrik. Dari data tekanan dan temperatur di setiap peralatan,
selanjutnya melakukan perencanaan heat exchanger, turbin, kondensor, dan feed
pump yang akan digunakan agar siklus binary cycle ini dapat beroperasi dengan
baik.
Fluida Kerja yang digunakan adalah n pentana dikarenakan memiliki entalpi
rendah yang bisa melewati temperatur kritisnya hingga menjadi superheated.
Perencanaan binary cycle didapatkan energi listrik sebesar 218 kW atau 0.218 MW.
Kata kunci: Binary cycle, Electric power, Entalpi rendah, n pentana
ABSTRACT
PLANNING OF THE USE OF BINARY CYCLE WORKING
FLUID USING SUSPEND WELLS IN THE DIENG FIELD

The IBN-2 well is an exploration well in the abandoned Dieng Geothermal
Field which is considered unproductive due to the low temperature of the well
obtained. Failed wells cannot be reused in conventional ways. So that a binary
cycle planning is carried out to take advantage of the IBN-2 well which has low
potential.
In planning a binary cycle, the first thing to do is to collect data from the IBN-2
well to determine the pressure (P), temperature (T), and mass flow rate (m) of the
heating fluid from the well head to the heat exchanger outlet. Next, calculate the
∆T of the heating fluid at the inlet and outlet of the heat exchanger to determine the
working fluid used in this binary cycle. After that, selecting the working fluid to
determine the pressure (P), temperature (T), mass flow rate (m), enthalpy (h), and
entropy (s) of the working fluid at the feed pump outlet, heat exchanger inlet, heat
exchanger outlet, turbine inlet, turbine outlet, condenser inlet, condenser outlet,
and feed pump inlet. Calculating the amount of enthalpy in the turbine to determine
the electrical energy. From the pressure and temperature data in each equipment,
then planning the heat exchanger, turbine, condenser, and feed pump that will be
used so that this binary cycle can operate properly.
The working fluid used is n pentane because it has a low enthalpy which can pass
its critical temperature to become superheated. Binary cycle planning obtained
electrical energy of 218 kW or 0.218 MW.
