Question

List 4 uses of CNG and LPG. plz anyone answer.​

Answer 1

Answer:

LPG - Liquefied petroleum gas or liquid petroleum gas, also denoted as just propane or butane, are both flammable hydrocarbon gases used as fuel for heating, cooking and vehicular fuel.

CNG - compressed natural gas storage cylinders have a tare weight approximately 3x heavier than comparable capacity LPG cylinders. LPG can be compressed into a liquid, increasing its energy density. The biggest difference between CNG and LPG cars is the fuel itself. CNG is methane and LPG is propane and/or butane.

CNG gas is compressed natural gas storage – methane. LPG is liquefied petroleum gas – propane.

There are many similarities between LPG and CNG, as well as some major differences…

CNG vs LPG differences and similarities• Chemical formula of CNG is CH4; Chemical formula of LPG is C3H8

• LPG has a higher energy content than CNG gas, with 25MJ/L versus 9MJ/L, respectively.

• Storage pressure of LPG is less than 2 MPa whilst CNG compressed natural gas storage is 20 – 25 MPa.

• For proper combustion, LPG requires an air to gas ratio of approximately 25:1 whilst the air to gas ratio for natural gas is a 10:1 ratio.

• LPG and natural gas appliances operate at different pressures – 2.75 kPa vs 1.1 kPa, correspondingly.

• LPG (propane) is denser than air at a relative density of 1.5219:1 vs natural gas (methane) at 0.5537:1, which is lighter than air.

• CNG - compressed natural gas storage cylinders have a tare weight approximately 3x heavier than comparable capacity LPG cylinders.

• LPG can be compressed into a liquid, increasing its energy density.
