Heavy vacuum gas oil cracking

[0010] Feedstocks most often subjected to hydrocracking are vacuum and atmospheric gas oils and heavy gas oils recovered from crude oil by distillation. The residue from the atmospheric tower contains gas oils that are not recovered. heater outlet temperature is limited due to the concerns over thermal cracking. Heavy vacuum gas oil (HVGO) is a side draw off the tower, and can be used to  

The heavier feed components in the blends cover heavy coker gas oil (HCGO), heavy vacuum gas oil (HVGO), light cycle oil (LCO) and deasphalted oil (DAO). These feed blends are processed in hydrocracking units with various objectives and flow schemes including single-stage once-through and recycle as well as two-stage and separate hydrotreat flow schemes. cracking units. The vacuum distillation consists of the vacuum furnace, vacuum tower and the vacuum producing system. The topped crude is heated up in the vacuum furnace to about 400 °C. The temperature is controlled to be just below the temperature of thermal decomposition. Although a single cut of vacuum gas oil (VGO) is allowed in The heavy vacuum gas oil from the vacuum distillation unit is processed by hydrocracking, a combination of catalyst cracking and hydrogenation. The unit also serves as an isomerisation processor improving the pour and low smoke properties of the end product of jet fuel and gas oil. Light vacuum gas Oil is sent to a hydrotreater and then to a ‘catalytic cracking’ unit to obtain smaller chain hydrocarbons. Heavy vacuum gas oil is also sent for cracking using hydrogen in a ‘hydrocracking unit’ to produce smaller chain hydrocarbons. Originating in the flashtower, the residuum receives more heating in a vacuum tower, where light vacuum gas oil and heavy vacuum gas oil are extracted from it. The remaining tarry solids left near the base of the tower are then sent through another heat exchange and furnace and on to the hydrocracking tower or "cracker" or they can be claimed as asphalt. A hydrocracking unit, or hydrocracker, takes gas oil, which is heavier and has a higher boiling range than distillate fuel oil, and cracks the heavy molecules into distillate and gasoline in the presence of hydrogen and a catalyst.

The main feedstock is vacuum gas oil, a heavy fraction of petroleum. The products of this process are saturated hydrocarbons; depending on the reaction conditions (temperature, pressure, catalyst activity) these products range from ethane, LPG to heavier hydrocarbons consisting mostly of isoparaffins. heavy vacuum distillates derived from refining crude oil cause cancer in laboratory animals.

These feed blends are processed in hydrocracking units with various objectives and flow schemes The feedstocks for catalytic cracking can be any one (or blends) of the flowing: (1) straight-run gas oil, (2) vacuum gas oil, (3) atmospheric residuum, and (4) vacuum residuum. More recently, heavy oil, extra heavy oil, and tar sand bitumen have been added to the feedstocks available for catalytic cracking but as blends rather than direct

A particular process of catalytic cracking, Fluid Catalytic Cracking, is almost exclusively used worldwide in heavy gas oil and light vacuum gas oil conversion. Aug 21, 2014 Vacuum distillation breaks out light and heavy gas oil fractions leaving to crack VGO into lighter gasoline blending components and diesel. FCC, Unicracking, and VGO Unionfining processes are the keys to cost-effective upgrading of Vacuum Gas Oil. These treating and conversion technologies,  Also known as: vacuum gasoil. VGO is one of The primary use of VGO is as feed to cracking units such as the FCC or the hydrocracker. oil. VGO is often sub-divided into a lighter and heavier fraction called LVGO and HVGO, respectively.
