The history of natural gas goes back thousands of years, but its fuel has become used only in the early 20th century. During this time, a classification of species appeared as gas fuel. We offer you a short digression into the terminology to understand the difference between natural, liquefied, and compressed gas.
The simplest hydrocarbon (an organic compound consisting of carbon and hydrogen atoms). It usually also contains heavier hydrocarbons: ethane (C2H6), propane (C3H8), butane (C4H10), and some non-hydrocarbon impurities. Natural gas can exist in the form of gas deposits located in the layers of certain rocks, gas caps (above oil), and in the dissolved or crystalline structure.
Compressed gas under pressure of 200-250 atmospheres, which reduces volume by 200-250 times.
Gas is compressed (compressed) for transportation through main gas pipelines to maintain the correct pressure within the reservoir (reservoir pressure) during underground injection, and also the production of CNG is an intermediate step in the production of liquefied natural gas (LNG).Natural gas cooled after purification from impurities to a condensation temperature (-161.5 ° C). The volume of gas during liquefaction is reduced by 600 times, which is one of the main advantages of this technology.
Natural gas in liquefied form is stored for a long time, which allows you to create reserves.
Before delivery directly to the consumer, LNG is returned to its original gaseous state at regasification terminals.
Liquid gas (propane-butane) is obtained during the processing of the associated gas. These are pure gases or special mixtures that can be used for home heating, as automotive fuel, and also for the production of petrochemical products. In Kazakhstan, LPG is mainly used as a motor fuel.
It should be noted that QazaqGaz NC JSC does not produce and sell liquefied gas.Today, most of the growing energy demand is met by hydrocarbons. At the same time, natural gas helps to ensure the transition to a low-carbon economy as renewable energy sources develop. Natural gas could be a great addition to renewables energy (RES).
Natural gas is the only fossil fuel that burns completely when use.
Comparing the use of natural gas with coal, the generation of electricity produces half the amount of carbon dioxide (CO2) and only one-tenth of other air pollutants.
Converting natural gas to a liquid state reduces its volume more than 600 times. This facilitates the transportation of gas to end users located in remote areas.
After being delivered to its destination, it is again converted to ordinary gas at regasification plants, and the gas can be pumped into pipelines for the transmission to consumers.
