LPG

What is LPG?

Liquefied petroleum gas (LPG) is the liquefied form of petroleum gases released during the extraction of crude oil and natural gas or during the refining of crude oil.

The primary components of liquefied petroleum gas (LPG) are propane, butane, propylene, butylene, and isobutane.

LPG

The process provided by this invention can produce high yields of LPG rich in propylene and butylene’s, meanwhile produce high yield of gasoline which has enhanced anti knocking ability and stability; and also produce diesel fraction, its quality is compatible to that produced by conventional fluid catalytic cracking process.

Riser pilot plant results show the yields(based on feed) as follows: LPG 30˜40 wt%, in which 67˜75 parts by weight are propylene and butylene’s (i.e. total yield of propylene plus butylene’s amounted to 20˜30 wt%); C5 + gasoline yields 45˜55 wt% with RONC of 91˜95, motor octane number(MONC) of 80˜84, induction period of 500˜1000 minutes and existent gum of 0˜3 mg/100 ml. Liquefied petroleum gas plus total liquid products are high up to 90 wt%.LPG to H2 ˜C2 ratio on weight basis is up to 8˜13:1.

Usage of Liquefied petroleum gas

Liquefied petroleum gas is a highly flammable mixture of the hydrocarbon gases which is widely used as a fuel in household cooking applications. It is also used as a fuel in some automobiles.
