OCTANE NUMBER
A rating of a gasoline in terms of its propensity to cause knocking.
Gasoline is not a chemical compound; it is a mixture of many different compounds. By 1882, experimenters noted that spark ignition internal combustion engines knocked more on some gasolines than on others. Ideally, when the spark ignites the fuel-air mixture in the cylinder of a gasoline engine, the flame front

What is Cetane Number ?
CETANE NUMBER
A rating on a scale used to indicate how quickly a fuel will ignite in a diesel engine, a figure of merit for diesel fuel as the octane number is a figure of merit for gasoline burned in spark ignition engines. A diesel engine run on a fuel with a lower cetane number than it was designed for will be harder to start, noisier, operate roughly and have higher emissions.

Advanced Partial Conversion Unicracking ( APCU )
UOP : Advanced Partial Conversion Unicracking
Introduction
The Unicracking process has proven to be effective in the production of clean fuels. This is especially true for cases where a partial conversion unicracking unit and a FCC unit are integrated. The Advanced Partial Conversion Unicracking (APCU) process is UOP’s latest advancement in the area of ultra-low-sulfur diesel (ULSD) production

Flare Gas Recovery Unit
Flare Gas Recovery
Flare Gas Recovery adalah salah satu metode yang digunakan untuk menurunkan flare loss dengan cara me-recover flare gas yang mempunyai nilai potensial untuk dijadikan sebagai feedstock (feed Hydrogen Plant), fuel ataupun product (seperti LPG). Flare Gas Recovery Unit ini juga dapat menurunkan emisi kilang dari produk samping pembakaran seperti NOX, CO, dan CO2.

Hydrogen Production - Steam Methane Reforming
Hydrogen Production - Steam Methane Reforming (SMR)
Introduction
In today's energy supply system, electricity, gasoline, diesel fuel, and natural gas serve as energy carriers. These carriers are made by the conversion of primary energy sources, such as coal, petroleum, underground methane, and nuclear energy, into an energy form that is easily transported and delivered in a usable form to

Advanced Process Control on DCS
Last month, I got very excited course at Japan Cooperation Center Petroleum (JCCP) during mid winter. I attended that course for around 3 weeks ( 5 - 22 February 2008) in JCCP office (Sunshine 60 Building, 57/58F, Higashi Ikebukuro, Toshimaku, Tokyo, Japan). The participants were from several countries : China (CNPC) , Colombia (Ecopetrol) , Indonesia, Iran (NIORDC) , Libya (AORC), Malaysia (

Derajat Pemisahan
Derajat pemisahan dapat diartikan sebagai tingkat kemurnian produk atau perolehan produk. Ketajaman pemisahan dapat diketahui dari gap antara dua produk yang berdekatan. Gap adalah beda antara titik distilasi 5% produk dengan titik distilasi 95% produklainnya yang lebih ringan. Semakin rendah nilai gap maka derajat pemisahan fraksi-fraksi menjadi tinggi.
