MGT PetrOil Company is a major producer, supplier and exporter of many petrochemical products in the Middle East which is located in Iran. MGT PetrOil Company has many years’ experiences in exporting and it is active in case of Bitumen supplying.
Iran holds the world's fourth-largest proved crude oil reserves and the world's second-largest natural gas reserves. Moreover, the world's top 10 oil producers and top 5 natural gas producers is belonging to Iran. The most important rout for exporting of oil from Iran and all Persian Gulf countries is the Strait of Hormuz, off the southeastern coast of Iran. Liquefied natural gas (LNG) volumes also flow through the Strait of Hormuz.
in 1963, (NPC) National Petrochemical Company was established to spearhead the development and policy-making for petrochemical industry in Iran. the oldest petrochemical industry in the Middle East is belong to Iran. proudly in ethylene production, Iran can be introduced as a second major producer after Turkey. During 1964-1977 Razi, Abadan, Pazargad, Ahwaz carbon black, Kharg, Farabi and Shiraz expansion projects were completed.
there are many evidences shows that Iranians have been using Bitumen since a dim and distant past and They used Bitumen for their famous stamps and vases, moreover they used to tar their boats and coffins.
straight reduction to grade via petroleum crude oil or a crude blend is The best refining process, which is used for producing Bitumen, that is using atmospheric and vacuum distillation. In the schematic, atmospheric distillation is used to physically separate light, lower boiling point, petrochemical and fuel fractions from the non-boiling component which is defined as atmospheric residuum.
To remove the last traces of the lighter fractions, and stopped molecules thermal transformation, the atmospheric residuum is showed into the unit of vacuum distillation. At decreased pressure it may divide to any remaining lighter fractions, as the boiling temperatures are lower and unwanted thermal cracking of the molecules is avoided.
The lighter fractions, like, vacuum Gas Oils, are removed at atmospheric equivalent temperatures of 345-400°C (650–750°F) and 370–450°C (700–850°F) leaving a high boiling point, high molecular weight hydrocarbon residuum. The atmospheric equivalent temperature to yield the vacuum residuum is normally increased up to 535°C (1000°F) and has a low volatility.
According to the specification grade requirements the vacuum residuum also would be able to used directly, further processed, or used as a blended Bitumen component. The non-distillable materials produced from distillation of atmospheric residuum under vacuum are defined by Asphalt (CAS# 8052-42-4) and Residues (petroleum) vacuum (CAS# 64741-56-6).
