Answers
Answer:
LPG – Liquefied Petroleum Gas. CNG-Compressed Natural Gas. Liquefied petroleum gas is also called liquid petroleum gas is a flammable blend of hydrocarbon gases applicable for fuel in heating, cooking, and automotive appliances.

HPG
It means gases to which the provisions of the Act apply. High pressure gases shall be classified according to their current state as compressed gases and liquefied gases, which are defined as follows. Moreover, pressure means gauge pressure.
(1) Compressed gas (except for compressed acetylene gas)
Gas falling under any of the following items:
(i) compressed gas whose pressure is not less than 1 MPa at its normal operating temperature and whose pressure is not less than 1 MPa currently (Gas A shown in the drawing below); or
(ii) compressed gas whose pressure is not less than 1 MPa at a temperature of 35 degrees Celsius (Gas B shown in the drawing below; Note that Gas B is also high pressure gas when its pressure is less than 1 MPa.)
(2) Compressed acetylene gas
Gas falling under any of the following items:
(i) compressed acetylene gas whose pressure is not less than 0.2 MPa at its normal operating temperature and whose pressure is not less than 0.2 MPa currently (Gas A shown in the drawing below); or
(ii) compressed acetylene gas whose pressure is not less than 0.2 MPa at a temperature of 15 degrees Celsius. (Gas B shown in the drawing below; Note that Gas B is also high pressure gas when its pressure is less than 0.2 MPa.)
(3) Liquefied gas
Gas falling under any of the following items:
(i) liquefied gas whose pressure is not less than 0.2 MPa at its normal operating temperature and whose pressure is not less than 0.2 MPa currently (Gas a shown in the drawing below); or
(ii) liquefied gas whose pressure is 0.2 MPa at a temperature of not more than 35 degrees Celsius (Gas b shown in the drawing below; Note that Gas b is also high pressure gas when its pressure is less than 0.2 MPa.); and
(iii) of liquefied gases other than those set forth in the preceding two items whose pressure is more than 0 Pa at a temperature of 35 degrees Celsius, liquefied hydrogen cyanide, liquefied methyl bromide, and liquefied ethylene oxide (specific liquefied gases); moreover, the Act does not apply to liquefied methyl bromide outside facilities for production.
Liquefied petroleum gas (LPG), also called LP gas, any of several liquid mixtures of the volatile hydrocarbons propene, propane, butene, and butane. It was used as early as 1860 for a portable fuel source, and its production and consumption for both domestic and industrial use have expanded ever since. A typical commercial mixture may also contain ethane and ethylene, as well as a volatile mercaptan, an odorant added as a safety precaution.
Liquefied petroleum gas (LPG) is recovered from “wet” natural gas (gas with condensable heavy petroleum compounds) by absorption. The recovered product has a low boiling point and must be distilled to remove the lighter fractions and then be treated to remove hydrogen sulfide, carbon dioxide, and water. The finished product is transported by pipeline and by specially built seagoing tankers. Transportation by truck, rail, and barge has also developed, particularly in the United States.
LPG reaches the domestic consumer in cylinders under relatively low pressures. The largest part of the LPG produced is used in central heating systems, and the next largest as raw material for chemical plants. LPG commonly is used as fuel for gas barbecue grills and gas cooktops and ovens, for gas fireplaces, and in portable heaters. In Europe, LPG water heaters are common. It is also used as an engine fuel and for backup generators. Unlike diesel, LPG can be stored nearly indefinitely without degradation. Compare liquefied natural gas.
