C2 Hydrogenation reactor

Below is the purpose of C2 hydrogenation reactors, except..

• to hydrogenate acetylene to ethylene and ethane.

• To remove acetylene which is poison to polymerization reaction

• The process also hydrogenates some methylacetylene and propadiene to propylene and hydrogenates butadiene to butenes

• To remove moisture at cracked gas

Hydrogenation reaction in reactor R-360 is exothermic. True or False

• True

• False

• No comment

Excessive N2 cause temperature R-360 to increase. True or false

• True

• False

What happen if acetylene breakthrough R-360?

• Product increase.

• C2 product Ethylene off spec

• Nothing happen

• Trigger SD-3

What is CYCLE TIMES of catalyst R-360?

• 5-6 years

• 10 years

• 13-15 years

• we can use until forever

What is the type of catalyst used in R-360 NC-1?

• mol sieve

• Nickel based

• Palladum based

• Sugar based

Under what condition will R-360 will trigger SD-2?

• Temperature reactor less than 200degC

• Excessive DMDS in Cracked gas

• Temperature cracked gas in the coil outlet 1000 degC

• Temperature reactor more than 200degC

Why there is no need to inject H2 into R-360

• because it will cause company to loss 1 billion per year

• H2 already existed in the cracked gas stream

• because technician lazy to inject

• Boss not order to inject

• 2

• 5

• 6

What is the symbol for acetylene?

• C2H8

• C2H6

• C2H2

• C2H3
