Hydrotreating or hydrodesulfurization refers to a set of operations that remove sulfur and other impurities (Figure 1). During hydrotreating, crude oil cuts are selectively reacted with hydrogen in the presence …

There are more than 1600 active hydrotreating units across more than 600 refineries globally with a combined capacity in excess of 400 million barrels per day (including all forms of hydrotreating but …

What is Hydrotreating? Hydrotreating is a catalytic chemical process used in refineries to purify petroleum fractions by removing undesirable elements such as sulfur, nitrogen, oxygen, and metals.

Minimization of cracking (or any other chemical change that is not needed for removing heteroatoms) and minimization of hydrogen consumption are the two principal objectives of hydrotreatment …

Oct 31, 2025 · Hydrotreating is a vital refinery process that involves the removal of impurities such as sulphur, nitrogen and other contaminants from petroleum feedstocks. It employs hydrogen under …

Hydrotreating is defined as an industrial refinery process that utilizes a high volume of hydrogen gas to remove undesired impurities such as sulfur, nitrogen, and oxygen from petrochemical feedstock, …

Jun 10, 2025 · Hydrotreating is a crucial process in the field of catalysis that plays a vital role in the production of clean fuels and petrochemicals. It involves the removal of impurities such as sulfur, …

Hydrotreating is the process of removing impurities like Sulfur, Nitrogen, Oxygen, metals, chloride, etc. from petroleum products like gasoline, kerosene, and diesel.

Jun 19, 2025 · In simple terms, hydrotreating involves treating petroleum fractions with hydrogen in the presence of a catalyst, aiming to eliminate or reduce various contaminants.

Hydrotreating is a catalytic chemical process to remove Sulfur (S), Nitrogen (N), Oxygen (O), and metals from straight run and cracked products. This “clean-up” also saturates olefins to yield easier-to …
