vacuum distillates and residue depend on the type of crude oil feed, the type of refinery and its downstream processing capacities. The major specifications for the most common products are (Watkins, 1979): • Catalytic cracking feedstock: Gas oils for catalytic cracking feedstock require a strict separation between distillate and residue.
The process of crude oil refining. Print. ... A process called cracking is used to produce more of the lower molecular weight hydrocarbons. This process breaks up the longer chains into smaller ones. There are many different industrial versions of cracking, but all rely on heating. ... The production of final petroleum products differs from ...
A process for regenerating spent cracking catalyst, especially spent fluid cracking catalyst, is provided, which includes subjecting a mixture of spent cracking catalyst particles and hydrogen to wave energy in the microwave range.
The modern petroleum refinery has a series of core process units that create clean gasoline and low sulfur diesel fuel. The first oil refinery unit is crude oil desalting. The desalter removes salt, water and other contaminants from crude oil prior to distillation in an atmospheric tower.

During the cracking process, coke deposits on cracking catalyst surfaces; this causes a significant reduction of catalyst activity and selectivity.
May 02, 1978· A process according to claim 1 wherein the cracking is carried out by bringing the steam and hydrocarbon feedstock into contact with the catalyst bed in counter current fashion. 6. A process according to claim 5 wherein the hydrocarbon feedstock is brought into contact with the catalyst bed under force of gravity.
Propylene Production and Manufacturing Process 06 November 2007 15:03 Source: ICIS The two main sources of propylene are as a byproduct from the steam cracking of liquid feedstocks such as naphtha as well as LPGs, and from offgases produced in fluid catalytic cracking (FCC) units in .
oil vs. naphtha comparisons of yield sets, major equipment sizes, and process economics. Our analysis indicates that the ExxonMobil process achieves a 100200/ton cost advantage visàvis naphtha cracking
Fluid catalytic cracking yields mostly gasoline and diesel, as well as some light gases. Hydrocracking yields kerosene instead of diesel. Fluid catalyst As the name implies, fluid catalytic cracking uses a freeflowing catalyst to help break apart molecules of heavy gas oil.
