Abstract
The production of liquid fuels from natural gas is gaining attention worldwide.
In the plant, one of the unit operation used is autothermal reforming (ATR) reactor
which serves to convert natural gas (methane) to syngas that consist of hydrogen and
carbon monoxide. This unit operations need to be studied before its implementation in
real industry. In this work, REQUIL model in ASPEN Plus V10 was used to simulate
an autothermal reforming (ATR) reactor. The simulated results obtained were first
compared with the simulation data from literature. The simulated results obtained by
ASPEN Plus showed that it is acceptable since the simulation values corroborated the
literature with errors range of 0.72% to 9.45%. Sensitivity analysis on the REQUIL
ATR model showed that reactor temperature (800 K to 1300 K), reactor pressure (20
bar to 50 bar), feed steam molar flowrate (200 kmol/hr to 3000 kmol/hr) and feed
oxygen molar flowrate (500 kmol/hr to 3000 kmol/hr) have significant effects on the
conversion of methane and syngas ratio. The methane conversion was increases when
the reactor temperature, feed steam molar flowrate and feed oxygen molar flowrate
were increase. While, it was decreases when the reactor pressure was increase. The
syngas ratio was decrease when increasing the reactor temperature, reactor pressure,
feed steam molar flowrate and it was decreases when increasing the feed oxygen molar
flowrate.
