Straight Run Kerosene
This fraction is usually the first side stream of a conventional atmospheric distillation unit. It may be cut to meet a burning oil specification or become a component in Jet Fuel finished product. Its cut range is usually between 360?F … Continue reading
Naphthas
There are usually two naphtha cuts produced from most crude. These are: Light naphtha (sometimes called light gasoline) Heavy naphtha. Both these streams are the bottom product of the debutanizer unit. They are separated in a naphtha splitter fractionation tower. … Continue reading
Refinery Gas and LPGs
In many refineries most of theC4’s and lighter are removed from the atmospheric column overhead distillate in the first column of the light end unit. This is the unit’s debutanizer column. Some refineries however chose to separate the light naphtha … Continue reading
Atmospheric Overhead Distillate
This is not strictly a cut but consists of all the light material in the crude absorbed into the total overhead distillate from the crude tower. This distillate, and in most cases, together with similar distillates from other processes form … Continue reading
Vacuum Residue
This is the bottom product from the vacuum distillation unit. Just as in the case of the atmospheric residue it has several options for its use in meeting the refinery’s product slate. In the case of the energy refineries it … Continue reading
Vacuum Distillation of Atmospheric Residue
In modern refinery practice the distillation of atmospheric residue is accomplished under high vacuum conditions in a specially designed tower whose internal equipment ensures a very lower pressure drop. Normally the vacuum conditions in the flash zone of the tower … Continue reading
Atmospheric Residue
This is the bottom product from the atmospheric distillation of the crude oil. Most crude oils are distilled in the atmospheric crude oil tower to cut the atmospheric residue at a +650?F up to a +680?F cut point. Cutting the … Continue reading
