Question 1

What is the primary difference between refinery and petrochemical processes?&#10;A) petrochemical processes have been around longer&#10;B) refinery processes have been around longer&#10;C) refinery processes are based on crude oil&#10;D) petrochemical processes are based upon chemicals

Accepted Answer

refinery processes have been around longer&#10;

Question 2

During WW-2, American manufacturers produced _____% of the aviation fuel used by the Allies.&#10;A) 25&#10;B) 40&#10;C) 80&#10;D) 95

Accepted Answer

American manufacturers produced 80% of the aviation fuel used by the Allies during World War II, playing a crucial role in the Allied war effort.

Question 3

The _________ process is designed to produce high-purity ________ and heavy aromatics from a mixture of toluene and heavier aromatics.&#10;A) paraxylene&#10;B) BTX aromatics&#10;C) xylene&#10;D) benzene

Accepted Answer

benzene&#10;

Question 4

What process is based upon extractive distillation and is designed to produce yields of benzene, toluene hydrogen, xylenes, and C5+?&#10;A) BTX aromatics&#10;B) paraxylene&#10;C) benzene&#10;D) ethylene glycol

Accepted Answer

BTX aromatics production involves extractive distillation, targeting the extraction of benzene, toluene, xylenes (the "BTX" components), and other related products from hydrocarbon streams.

Question 5

The raw feed stock for an (a) ______ ______ unit includes refined ethylene oxide and pure water.&#10;A) iron oxide&#10;B) ethylene glycols&#10;C) ortho xylene&#10;D) BTX aromatics

Accepted Answer

The raw feedstock for an ethylene glycols unit includes refined ethylene oxide and pure water, as ethylene glycols are produced by the hydration of ethylene oxide.

Question 6

What three processes are associated with olefins production. Circle three!&#10;A) natural gas or raw methanol to ethylene, propylene, and butene.&#10;B) hydrocarbon feed stock to isobutylene and isoamylene feed stocks.&#10;C) gas oil feed stocks into high octane gasoline and distillate, and C2-C5 olefins.&#10;D) takes mixed xylenes from reformers or steam crackers to produce high purity paraxylene.

Accepted Answer

A) This process involves converting natural gas or methanol into olefins like ethylene, propylene, and butene.  B) This process involves converting hydrocarbon feedstock into olefins such as isobutylene and isoamylene.  C) This process involves converting gas oil feedstocks into olefins like C2-C5 olefins, along with high octane gasoline and distillate.

Question 7

Polyethylene, linear polyethylene or linear low density polyethylene is closely associated with:&#10;A) plastics&#10;B) rubber&#10;C) steel&#10;D) ethylene oxide

Accepted Answer

Polyethylene, including its linear forms, is a type of plastic widely used in various applications, from packaging to containers.

Question 8

There are ___ common refining processes used by industrial manufacturers.&#10;A) 19&#10;B) 29&#10;C) 38&#10;D) 49

Accepted Answer

The answer of There are ___ common refining processes used...

Question 9

Alkylation units take two small molecules of iso-butane and olefin (propylene, butylenes or pentylenes) and combines them into one large molecule of high-octane liquid called _______.&#10;A) propylene&#10;B) pentane&#10;C) alkylate&#10;D) methane

Accepted Answer

Alkylation units combine iso-butane and olefins to produce alkylate, a high-octane liquid used in gasoline blending.

Question 10

Fluid catalytic cracking units take gas oil and&#10;A) splits it into smaller, more useful molecules.&#10;B) combines it into a larger molecule&#10;C) burns off the excess coke&#10;D) blends it with xylenes

Accepted Answer

Fluid catalytic cracking units break down heavier fractions of crude oil into smaller, more valuable hydrocarbon molecules, making them more useful for various applications.
