"A lot of biomass processing technologies resemble a petroleum industry process called hydrotreating, which uses a lot of hydrogen," Bond said. ❋ JT McLain (2010)
Next comes distillation, thermal conversion, catalytic conversion, and hydrotreating. ❋ The Media Consortium (2011)
The quality of pygas, which is high in diolefin content, can be satisfactorily improved by hydrotreating, whereby conversion of diolefins into mono-olefins provides an acceptable product for motor gas blending. ❋ Unknown (2008)
Typically, hydrotreating is done prior to processes such as catalytic reforming so that the catalyst is not contaminated by untreated feedstock. ❋ Unknown (2008)
Naphtha produced from steam cracking contains benzene, which is extracted prior to hydrotreating. ❋ Unknown (2008)
In addition, hydrotreating converts olefins and aromatics to saturated compounds. ❋ Unknown (2008)
Lube-oil hydrotreating uses catalytic treatment of the oil with hydrogen to improve product quality. ❋ Unknown (2008)
Catalytic hydrotreating is a hydrogenation process used to remove about 90% of contaminants such as nitrogen, sulfur, oxygen, and metals from liquid petroleum fractions. ❋ Unknown (2008)
The liquid stream is the product from hydrotreating and is normally sent to a stripping column for removal of H2S and other undesirable components. ❋ Unknown (2008)
In addition, diesel sulfur levels are slated for a major reduction from 500 parts per million to 50 ppm by 2010, requiring significant additional hydrotreating capacity. ❋ Unknown (2008)
The objectives in mild lube hydrotreating include saturation of olefins and improvements in color, odor, and acid nature of the oil. ❋ Unknown (2008)
Severe lube hydrotreating, at temperatures in the 600°-750° F range and hydrogen pressures up to 3,000 psi, is capable of saturating aromatic rings, along with sulfur and nitrogen removal, to impart specific properties not achieved at mild conditions. ❋ Unknown (2008)
Mild lube hydrotreating also may be used following solvent processing. ❋ Unknown (2008)
Catalytic hydrotreating processes such as hydrodesulfurization remove sulfur compounds from refinery product streams. ❋ Unknown (2007)
So we actually have to look at the volume of material we are hydrotreating.
Of course, as the volumes become much higher in the base, then we would hit physical limits on the hydrotreating capabilities.
What we're seeing is consistent with the operational excellence drive, we've been focusing on hydrotreating and we are seeing the reliability, both our hydrogen plants and hydrotreaters increase.
