Abstract Production of liquefied natural gas (LNG) from natural gas is justified in the case of transport by LNG mobile machines. LNG has a temperature of -164 °C and density of 460 kg/m3. Density of gas at normal pressure is 0.75 kg/m3, whereas LNG has a density over 640 times the density of natural gas. In other words, the equivalent of 1.5 litres LNG is 1 m3 of natural gas. The transport of 1 tonne of LNG to the designated location is equivalent to 1400 m3 of natural gas. A consumption of 6 million tonnes of LNG per year is equivalent to a 300 MW power plant energy production; or approximately 70000 m3/h water consumption. The conversion of natural gas to a liquid state is carried out in several stages. First, all impurities are removed, primarily carbon dioxide, and sometimes minimal balances of sulphuric compounds. The gas is then gradually cooled until it reaches approximately -164 °C. Water is then removed that could otherwise turn into ice crystals and block installation components. The next step is the removal of most heavy hydrocarbons. Keywords: liquefied natural gas (LNG), production, energy, transport |
