5 Sanity-Saving Tips for Arguing on the Internet
Combustion
...exothermic reaction that requires fuel, oxygen and heat
ex. furnace
,Endothermic reactions absorb...
...energy as they proceed. Heat must be added to form the product
Exothermic reactions are characterized by...
...a chemical reaction accompanied by heat's liberation (removal)
An inhibitor is a substance that prevents...
...the reaction of two or more chemicals
Material balancing is a method used by technicians to determine...
...the exact amount of reactants needed to produce the specified
products when two or more substances are combined
Neutralization reactions remove...
...hydrogen ions (acid) or hydroxyl ions (base) from a liquid
Hydrogen ions and ____ ions neutralize each other
...hydroxyl
Industrial manufacturers use replacement reactions to...
...remove dissolved mineral ions from process water
Stirred Reactor:
1. The basic components include a...
2. The ___ is designed to be heated or cooled and withstands
operational pressures, temperatures, and flow rates.
3. The ___ mixes two or more components into a homogeneous
mixture.As these components blend, chemical reactions create a
new product.
4. ___ are sized to handle and contain any release from the reactor.
5. ___ are designed to stop the reaction process.
6. ___ allow process releases to go to the plant flare system.
7. Alkylation units take two small molecules, ___ & ___ (propylene,
butylenes, or pentylenes), and combine them into one large
molecule of high-octane liquid called alkylate.
8. Alkylate is a superior antiknock product used in blending ___
, 1. mixer or agitator mounted to a tank.
2. reactor shell
3. stirred reactor
4. Pressure relief systems
5. Quench systems
6. Safety relief systems
7. Isobutane and Olefin
8. Unleaded gasoline
A ___ (often called a converter) is a vessel that contains a mass of
small particles through which the reaction mixture passes. The mass
is usually a packed “bed” of ___ , which promotes the reaction. The
mass could also be column packing. ___ support the catalyst.
1. Fixed bed reactor/ catalyst/ trays
___ is a process used by industrial manufacturers to “sweeten” the
mixture by removing the sulfur. Crude oil contains hydrocarbons,
clay, water, and sulfur. High concentrations of sulfur in crude oil are
referred to as ___
Hydrosulfurization/ sour feed crude
___ is a process that industrial manufacturers use to boost gasoline
yields. The process takes heavy gas oil molecules and splits them
into smaller, lighter molecules called hydrocrackate.
Hydrocracking
A ___ suspends solids by the counter-current flow of gas from the
bottom of the reactor. Over time, particles segregate as heavier
components fall to the bottom, and lighter ones move to the top.
fluidized bed reactor
Crude oil is first processed in a pipe still, and the side-stream has
light gas oil. ___ (catcracking) units take the gas oil and split it into
smaller, more valuable molecules.
fluid catalytic cracking
