CNG

CNG is an abbreviation for Compressed Natural Gas, where CNG is compressed natural gas that can be used as an alternative fuel for small and medium-sized industrial markets. CNG is distributed using Cradle and Pressure Reducing System technology that is safe and simpler, so it does not require a large area.

CNG GASRA

CNG for small and medium-scale industries with the product name GASRA.

PT CEI focuses on retail industries such as hotels, restaurants, and catering that use gas as their main fuel for business.

We have created a technology called Pressure Reduction Station that can be applied in this retail industry with the function of reducing the pressure of CNG gas from inside the cylinder from 250 bar to 0.8 - 1.5 bar, adjusting to the needs of the customers.

CNG (Compressed Natural Gas)

​CNG ​

 
​
  • * Predominantly composed of methane (CH₄) gas, typically ranging from 85% to 98%.
  • * Contains minimal amounts of other hydrocarbons such as ethane, propane, and butane.
  • * Usually, CNG also contains small quantities of non-hydrocarbon gases like nitrogen, carbon dioxide, and hydrogen sulfide.

LPG (Liquefied Petroleum Gas)

​LPG



  • * Primarily consists of propane (C₃H₈) and butane (C₄H₁₀), with propane being the main component.
  • * The typical composition is around 60% propane and 40% butane.
  • * LPG may also contain small amounts of other gases such as ethane and propylene.

           Diesel                         Fuel

​DIESEL


  • * Diesel fuel is not a gas but a liquid hydrocarbon fuel primarily derived from crude oil.
  • * It consists of various hydrocarbons, including alkanes, cycloalkanes, and aromatic hydrocarbons.
  • * The specific composition of diesel fuel can vary depending on its source and refining process.
  • * Diesel fuel typically has a higher energy density compared to CNG and LPG due to its liquid state.

Here is a comparison between CNG (Compressed Natural Gas), LPG (Liquefied Petroleum Gas), and Diesel from various aspects, including calorific value, density, storage phase, pressure, and calculation:

CNG 

(Compressed Natural Gas)


* CNG: CNG has a relatively high calorific value because it mainly consists of methane (CH₄), which has a high calorific value.

LPG 

(Liquefied Petroleum Gas)

* LPG: LPG has a lower calorific value compared to CNG because it mainly consists of a mixture of propane (C₃H₈) and butane (C₄H₁₀).

Diesel

* Diesel: The calorific value of diesel fuel is usually higher than LPG but lower than CNG because it is a liquid and has a different molecular structure.
