Gasoline

Gasoline:  A  fuel  for  petrol  engines,  gasoline  is  classified  by  its  octane  rating,  which  indicates  its  resistance  to  “knocking”  or  “pinging”  during  combustion.  Under  state  regulations,  IRPC’s  gasoline is divided into ULG91 lead-free gasoline, GSH95 and GSH91 gasohol, and gasohol base, the last of which is used to manufacture gasohol and E20.

Diesel

Diesel: Diesel is a fuel for high-speed diesel engines used in the industrial sector and vehicles, such as cars, trucks, fishing trawlers, passenger boats, and tractors. IRPC offers blends of 5-7% biodiesel as per government policy to promote the use of alternative energy and palm oil. Furthermore, as per government policy, B10 is the standard diesel in Thailand, while B7 and B20 are alternatives. IRPC began selling B20 by mid-2018; and B10 at the end of 2019

Fuel oil

Fuel oil: A fraction of crude oil with a high boiling point, fuel oil is widely used in the industrial sector, transportation, and power generation.

Liquified petroleum gas (LPG)

Liquified  petroleum  gas  (LPG):  A  mixture  of  hydrocarbon gases, mainly propane and butane, LPG  is  commonly  found  in  household  kitchens  and various other industries. It can also be used as a fuel or gasoline engines.

Lube base oils

Lube base oils refer to heavy distillates used for  producing  different  grades  of  lubricants.  IRPC  produces the following grades of base oil for various purposes and applications: 

150 SN  is  the  feedstock  for  the  automotive  and  transport industries, among others.

500 SN  is the feedstock for lubricants used in most  vehicles.

150 BS  is used in industries and engines involving  high  friction,  such  as  those  in  trucks, locomotives, and seagoing vessels.

In addition to these products, IRPC has researched and  developed  other  innovative  base  oils-namely, Treated Distillate Aromatic Extract (TDAE) and Residue Aromatic Extract (RAE). These serve as feedstocks  for automotive tires and contain reduced Polycyclic Aromatic Hydrocarbons (PAHs), which is a carcinogen, meaning they are safer for consumers’ health.

Asphalt

Asphalt: Asphalt, also called bitumen, is a compound of hydrocarbons and other organic substances. Thick and viscous, asphalt is the heaviest portion obtained from the crude oil distillation process. It is used for road construction and waterproofing.

Naphtha

Naphtha  refers  to  light  distillates  obtained  from  the oil refining process. It is a major petrochemical  feedstock.
