Was passiert in der Erdölraffinerie?
Eine Erdölraffinerie ist ein Industriebetrieb, der den Rohstoff Erdöl durch Reinigung und Destillation unter Normaldruck und unter Vakuum in Fraktionen mit einem definierten Siedebereich überführt. Die weitere Verfeinerung erfolgt durch Verfahren wie Extraktion oder chemische Reinigungsverfahren.
Was macht man in einer Raffinerie?
Eine Raffinerie ist ein Betrieb, der aus Naturstoffen durch Reinigung und Veredelung (Verarbeitung) höherwertige Produkte herstellt.

What is the purpose of a hydrotreater?
The purpose of a hydrotreater unit is primarily to remove sulfur and other contaminants from intermediate streams before blending into a finished refined product or before being fed into another refinery process unit.
What is the operating temperature of a hydrotreater?
The typical process flow scheme for a hydrotreater, with the main temperatures for each feedstock, is shown in Figure 3. The operating temperature for naphtha desulfurization is of the order of 700°F, but this varies as a function of the catalyst activity and stringency of the treatment.
What is hydhydrotreating and how does it work?
Hydrotreating processes aim at the removal of impurities such as sulfur and nitrogen from distillate fuels—naphtha, kerosene, and diesel—by treating the feed with hydrogen at elevated temperature and pressure in the presence of a catalyst.
What is a hydrotreating reactor?
A hydrotreating reactor is a fixed bed and downward flow reactor with Alumina base Ni-Mo (for Nitrogen removal and aromatics saturation) and Co-Mo (for sulfur removal and Olefin Saturation) catalysts. In addition, guard or grading catalysts are present at the top of the main catalyst to remove metals or particles from the reactor feed.
