Base oil (N150 / N350)

Base oils are used to manufacture products including lubricating greases, motor oil and metal processing fluids. Different products require different compositions and properties in the oil. One of the most important factors is the liquid’s viscosity at various temperatures.

Almost every lubricant used in plants today started off as just a base oil. The American Petroleum Institute (API) has categorized base oils into five categories. AT HHY, we provide group-I and group-II base oil.

Our main products N150 and N350:

  • Light-grade base oil in the middle of the specifications.
  • Solvent refined.
  • Main components for lubricants and functional fluids
  • N150
    • Common in mineral based motor oils currently available on the market
    • Fair to good performance in lubricating properties such as volatility, oxidative stability and flash/fire points
    • With Viscocity Index over 100 and flash point over 200
  • N350
    • Mainly used in lubricant and lubricant additives production
    • Contain less than 90 percent saturates and has a viscosity index greater than or equal to 85 and less than 120.

Naphtha contains varying amounts of its constituents viz., paraffin, naphthenes, aromatics, and olefins in different proportions in addition to potential isomers of paraffin that exist in the naphtha boiling range.

Naphtha is the first petroleum product produced during the distillation process and subsequently upgraded to make the major components of gasoline. Virgin or straight-run Naphtha is the largest source of Naphtha in most petroleum refineries.

  • a general category of hydrocarbons that are volatile
  • commonly used as a solvent.
  • It is used in hydrocarbon cracking, laundry soaps, cleaning fluids, and as a solvent for paint.
Diesel oil

Diesel is produced from the fractional distillation of crude oil at the oil refineries. Diesel is used in various applications throughout many industries. These includes automotive diesel engines, marine boats, industrial boilers, generator sets and other industrial applications.

  • Used as fuel for diesel engines.
  • Applied in various production / process / operation throughout many industries.
  • Releases more energy on combustion than equal volumes of fuel
  • Generally produce better fuel economy than fuel engines.
  • Diesel for industrial use is commonly stored in skid tanks
Fuel oil

Fuel oil is the heavier fraction of the crude oil that remains after the extraction of the higher valued distillates. Broadly speaking, fuel oil is any liquid petroleum product that is burned in a furnace or boiler for the generation of heat or used in an engine for the generation of power.

Some of the common use in Malaysia are in industries for process heating, steam generation and power generation, and as bunker fuel for marine vessels.

  • A dark heavy hydrocarbon
  • For process heating, steam generation and power generation
  • Used in boilers and furnaces for heating homes and buildings, for industrial heating, and for producing electricity in power plants
  • Similar to Diesel, fuel oil is also commonly stored in skid tanks.
