Due to the limited sample size atmospheric distillation profiles using classic techniques (ASTM D86) was not possible.
Naphtha is a hydrocarbon intermediate that is generally produced during the refining of crude oil in the atmospheric distillation unit (ADU/CDU) of a refinery, which is also the primary source.
These gases are primarily obtained from atmospheric distillation of air, with some of them also being sourced from natural gas and rock sediments.
In an oil refinery, primary distillation occurs in a crude distillation tower, also known as a crude distillation unit or an atmospheric distillation unit.
The company, officially known as Petroleo Brasileiro, restarted gasoline output from its atmospheric distillation systems at the Reduc refinery outside Rio de Janeiro, according to Simao Zanardi, president of the union known as Sindipetro Duque de Caxias.
They address catalytic reaction processes, such as fluid catalytic cracking, catalytic reforming, and hydroprocessing, together with upstream fractionation units, such as atmospheric distillation unit and vacuum distillation unit, as well as downstream fractionation units following the catalytic reaction processes.
He indicated that several projects are being carried out at the refinery to achieve the hoped-for goals such as the project of rehabilitating oxygen analyzers with a cost of SYP 25 millions, the project of modifying the atmospheric distillation unit No.
The complex is proposed to have an atmospheric distillation unit, a heavy naphtha hydro-treating reformer, a light gas-oil hydrocracker, a delayed coker hydrocracker and sulphur plants.
Although the refining process is complex, the flowsheet is very simplified, showing only an atmospheric distillation column, a vacuum distillation column, a fluid catalytic cracker, a hydrogen plant, a catalytic reformer, and a sulfur plant.
Foster Wheeler's scope comprises a new 15,000 barrels per stream day (BPSD) continuous catalytic reformer, modification of the existing atmospheric distillation unit in order to switch the operation from high to low sulphur crudes and revamp of the existing naphtha hydrofiner and crude light ends processing unit to increase to 26,000 BPSD the refinery's processing capacity for the light products.
