PPE 2 Flashcards
This process involves breaking down large hydrocarbon molecules into smaller ones by the use of a catalyst
Catalytic Cracking
In a _______ process, solid particles are suspended and behave like a fluid when a gas (usually air) is passed through them at a sufficient velocity.
Fixed Bed Process
In a _____ process, the solid move through a reactor or vessel while the fluid flows countercurrently or concurrently.`
Moving Bed Process
Generally refers to the process of thermal decomposition or cracking of heavy hydrocarbons into lighter fractions.
Coking
The heavy oil vapors are heated in a pre heater to cracking temperature
420 ℃ - 450 ℃
is the process where the gasoline is heated in suitable temperature and the remaining gases are removed to collect a pure gasoline.
Stabilizer
A type of catalytic cracking process where petroleum vapor passes through a low-density bed of catalyst, which causes the heavier fractions to ‘crack’ producing lighter more valuable products
Fluid Bed Process
This process uses the unitary vessel design, which provides a straight-line fow of catalyst and thereby minimizes the erosion encountered in pipe bends
Orthoflow fluid-bed catalytic cracking
This unit involves a procedure in which the catalyst is transferred between the reactor and regenerator by means of U bends, and the catalyst flow rate can be varied in relation to the amount of air injected into the spent-catalyst U bend.
Model IV - Fluid Bed Catalytic Cracking
A catalytic cracking process for upgrading heavy feedstocks, such as topped crude oils, vacuum residua, and solvent deasphalted bottoms using a fluidized bed of iron ore particles
Heavy Treating Oil Process
It is a specialized process configuration used in petroleum refineries and indicates the use of two regenerators in the process.
R2R Process
This process uses heavy residual oil which requires a different catalyst to the used in the FCC process.
Reduced Crude Oil Conversion Process
A type of catalyst used as cracking catalysts possessing strong acidic properties, and function as catalysts by altering the cracking process mechanisms through an alternative mechanism involving chemisorption by proton donation and desorption, resulting in cracked oil and theoretically restored catalyst.
Insulator Catalyst
TRUE OR FALSE: METX is a process that only consists of cooling, and ion-exchange separation, and resin regeneration.
False
This is the latest technique developed by the refining industry to increase gasoline yield and quality. Here, the catalysts are treated from the cracking units to remove metal poisons that accumulate on the catalyst.
