Which acid is used in petroleum refining industry?
The process using hydrofluoric acid as catalyst is performed at temperatures between 30 and 43 °C (85 and 110 °F) while the process using sulfuric acid operates from 4 to 13 °C (40 to 55 °F).
What chemicals are used in oil refinery?
Potential Chemical Exposure by Process

| Hydrogen chloride |
What is used as catalyst in petroleum refining?
The catalysts used in catalytic cracking process are mainly zeolites, similar to those used in petroleum refinery. ZSM-5, Y, silica-alumina, SAPO, MCM-41, SBA-15 and other zeolites were applied in this process to remove oxygen from bio-oils.
How is Sulphuric acid used in petroleum refining?
Another key application is in petroleum refining, where the acid is used as a catalyst in the alkylation process for the production of high-octane gasoline. In many industries, including refining, after the sulfuric acid has performed its function, it becomes partly neutralized (i.e., spent).
Why is Sulphuric acid used in petroleum refining?
It is used in petroleum refining to wash impurities out of gasoline and other refinery products. Sulfuric acid is used in processing metals, e.g., in pickling (cleaning) iron and steel before plating them with tin or zinc. Rayon is made with sulfuric acid.
How is sulfuric acid used in oil refining?
What is the chemical formula of oil?
Its chemical formula, C8H18, reflects the fact that each of the carbons is covalently bonded to one or two of the other carbon atoms and two to three hydrogen atoms.
What is a refining catalyst?
Refining catalyst can be defined as any dual functioning chemical substance that is used in refineries to facilitate the refining process of crude materials and simultaneously regulate the rate of the chemical reaction.
Where is naphtha used?
The main uses of petroleum naphtha fall into the general areas of (i) precursor to gasoline and other liquid fuels, (ii) solvents (diluents) for paints, (iii) dry-cleaning solvents, (iv) solvents for cutback asphalts, (v) solvents in rubber industry, and (vi) solvents for industrial extraction processes.
What is gas oil in refinery?
Gasoil is a broad term that can refer to a range of intermediates and finished petroleum products, generally in the diesel or VGO range of distillation profile. Heavy atmospheric gasoil (HAGO) – Straight run material in between the diesel and VGO range from the atmospheric distillation tower. …
