New international regulations aimed at decarbonizing maritime transportation are positively contributing to attention being paid the use of liquefied natural gas (LNG) as a ship fuel. Scaling up LNG-fueled ships is highly dependent on safe bunkering operations, particularly during simultaneous operations (SIMOPs); therefore, performing quantitative risk assessment (QRA) either mandated or recom...

About 10 years ago, Korea Gas Corporation (KOGAS) carried out a feasibility study on businesses using Liquefied Natural Gas (LNG) for cold power generation, air separation, cryogenic crushing, frozen food storage, and carbonic acid. Recently, an air liquefaction plant started operations near Pyungtaek Receiving Terminal (R/T) and a cryogenic crushing plant is now partially operating near Tongyo...

The demand for natural gas (NG) in Thailand has been continuously increasing, but part of NG volume not distributed to customers locating far from the pipeline network. Therefore, is transported by trucks liquid form called liquefied (LNG) meet demand. However, road transportation truck causes many problems such as high cost, low capacity, poor environmental conditions, and safety. To solve the...

Two types of combustion instabilities were observed in a multi-injector research combustor with liquid oxygen and liquefied natural gas (LOX/LNG) propellants operating at conditions similar to an upper stage rocket engine. The first was identified as excited tangential acoustic mode the chamber can be explained by coupling LOX injectors, mechanism previously tests propellants. other type is cha...

Abstract The scarcity of freshwater resources in the marine environment drives advancement conventional desalination technologies. It is appealing to recover waste thermal energy power process. With fast expansion global fleet liquefied natural gas (LNG) powered vessels and number LNG terminals, it envisaged that cryogenic becomes an important form apart from engine exhaust. A generator assiste...

As the use of fossil fuels becomes more and restricted there is a need for alternative also at sea. For short sea distance travel purposes, batteries may be solution. However, longer distances, when no possibility recharging sea, do not have sufficient capacity yet. Several projects demonstrated compressed hydrogen (CH2) as fuel road transport. The experience with maritime very limited. In this...

A new concept of land-based Atlantic salmon farming utilizing liquefied natural gas (LNG) cold energy is proposed. In this study, laboratory-scale experiments were conducted using liquid nitrogen as a source to confirm whether the water temperature fish tank can reach below 17 °C within an hour. particular, effects mass flow rates (0.0075, 0.01, and 0.0125 kg/s) (0.05, 0.1, 0.15 on cooling perf...

Transport of liquefied natural gas (LNG) by ship occurs globally on a massive scale. The large temperature difference between LNG and water means will boil violently if spilled onto water. This may cause physical explosion known as rapid phase transition (RPT). Since RPT results from complex interplay phenomena several scales, the risk its occurrence is difficult to estimate. In this work, we p...

Iran’s environmental condition is critical, since it is experiencing desertification, unsustainable development and overpopulation. The objective of this study is power source replacement in natural gas stations that operate with natural gas compressors, through using electrical motors, which can be fed by a 160 MW geothermal power plant, as an alternative to gas turbines. Application of such a...
