Liquefied Gas

The importance of liquefied natural gas (LNG) vessels and the technology that enables their operations is steadily growing. Hence, in addition to professional interest, the general public also displays a considerably large interest in this issue. Today LNG carriers belong to the category of the most technologically developed vessels and therefore managing these vessels requires not only the general knowledge but also the specific knowledge relating to their cargo handling systems. To ensure the safe and economical transport of LNG by sea and to minimize the risk of fire or explosion it is necessary to understand the properties of LNG and nitrogen, an inert gas used in all phases of the carriage and transfer of liquefied gas. The subject of this research is the overall process of nitrogen management in daily operations on board LNG carriers. The aim of the research is to explain, evaluate and define the various applications of nitrogen systems on LNG carriers.

The increase in demand for natural gas in the world, cause that the production of liquefied natural gas (LNG) and in consequences its regasification becoming more common process related to its transportation. Liquefied gas is transported in the tanks at a temperature of about 111K at atmospheric pressure. The process required to convert LNG from a liquid to a gas phase for further pipeline transport, allows the use of exergy of LNG to various applications, including for electricity generation. Exergy analysis is a well known technique for analyzing irreversible losses in a separate process. It allows to specify the distribution, the source and size of the irreversible losses in energy systems, and thus provide guidelines for energy efficiency. Because both the LNG regasification and liquefaction of natural gas are energy intensive, exergy analysis process is essential for designing highly efficient cryogenic installations.

Storage tanks are widely used in the oil refinery and petrochemical industry in storing a multitude of different products ranging from gases, liquids, solids, and mixtures. Design and safety concerns have become a priority due to tank failures causing environment pollution as well as fires and explosions, which can result in injuries and fatalities. The chapter illustrates different types of crude oil and oil product storage tanks as well as the risks regarding the storage itself. Considering that the natural gas, in its gaseous state, is stored in underground storages like oil and gas depleted reservoirs, aquifers or salt caverns, and there are numerous publications and books covering the subject in detail, this chapter only illustrates the storage of liquefied natural gas and the risks posed by its storage.

In this paper we research the development and competitiveness of the LNG (Liquified Natural Gas) market in the European Union, especially in its member states located in west and south of Europe. First, we analyze legal and regulatory framework at the EU level, under which LNG terminals and facilities operate. In addition to content analysis, we also compare trends in the European LNG market with trends in other regions, especially in the Asian LNG market. The result of the research highlights the changed structure of the EU's gas market, characterized by larger imports of liquefied natural gas, especially since the end of 2018, as well as increased number of terminals and capacities for receiving liquefied gas. However, the growth in the share of liquefied gas in total import was not linear in the previous years. As a part of the discussion we examine three possible scenarios regarding the future of LNG market in the European Union, and we conclude that the perspective of LNG in the market will primarly depend on price competitiveness comparing it to pipeline gas transport.

In this paper, the analysis of liquefied natural gas process plant technology, into the device before the natural gas compression, and then through the MEA aqueous solution to remove CO2. Finally, the compressed water removed; clean natural gas before entering the liquefaction unit. In the liquefaction unit, the high-pressure natural gas is cooled and liquefied deep. The required cooling capacity is obtained by circulating the gas turbine to drive the closed mixed refrigerant nitrogen, methane, ethylene, propane and other components, and liquefied natural gas (LNG), which is finally stored in an atmospheric tank through a liquefied natural gas container or liquefied natural gas tanker for distribution. The recycle of the recycle refrigerant is carried out by means of environmental conditions. The heating medium required during the installation process is the hot oil heated by the exhaust gas of the gas turbine. The liquefied gas in the liquefied natural gas tank is compressed to regenerate the desiccant and then sent to the gas turbine as the fuel gas.

Subject Asian liquefied gas markets. Significance India has overtaken South Korea as the second-largest buyer of spot and short-term cargoes of liquefied natural gas (LNG), with the percentage of its LNG imports from such cargoes -- based on contracts of four years or less -- rising by 45% in 2015 over 2014. With global gas prices likely to remain low through to 2020, transforming what was a seller's market only two years ago into a buyer's market, a structural shift is underway in the demand for imported LNG in South and East Asia. Impacts The pipeline of new LNG supplies that will be added to the market in the next few years will ensure a buyer's market through to 2020. A persistently low global price could see Asian buyers opting for smaller volumes and shorter contracts for LNG imports. Sustainability of demand growth in new markets such as India will depend on the speed of expansion of infrastructure.
