Difference between LNG, LPG and NGL




✅ LNG — Liquefied Natural Gas, is gas that has been Liquified at very low temp. and is transported as a liquid. It’s Primarily methane ,NG is a mixture of HC which, when liquefied, form a clear colorless,odorless liquid; it’s usually transported and stored at a temp. very close to its boiling point at atmospheric pressure (~ -160), The actual composition of LNG will vary depending on its source and on the liquefaction process, but in all cases the major is methane with small percentages of the heavier HC such as ethane, propane, butane and pentane ,N2 may be present. 

✅ LPG — Liquefied Petroleum Gas gas that is liquid near room temperature and at some extent of pressure. This product has very little methane and butane and is primarily propane (C3),LPG is more dense (has a higher specific gravity) than natural gas ,Their common characteristic is that they can be compressed into liquid at relatively low pressures ,The two most common LPG constitutes are Propane and Butane.

 ✅ NGLs — Natural Gas Liquids,are heavier gaseous hydrocarbons that are included in the raw natural gas stream from the wellhead , Raw natural gas also contains impurities including water vapor,(H2S), CO2, helium, N2, and other compounds that must be removed.
