Liquefied natural gas (LNG) is a vital source of energy for many countries around the world. In order to transport it efficiently over long distances, LNG is cooled to around -160°C, which turns it into a liquid that can be transported by tanker ships. However, before it can be used as a fuel, the LNG must be regasified - or converted back into its gaseous form. In this article, we will explore how LNG regasification works and why it matters for energy markets. Ambient Air Vaporizer Skid ( Chart Industries ) How LNG Regasification Works LNG regasification is typically done at specialized import terminals, which are designed to receive, store, and process LNG. The regasification process involves several key steps: Storage: The LNG is pumped from the tanker ships into large storage tanks at the import terminal. These tanks are typically insulated and designed to keep the LNG at a constant temperature of around -160°C. LNG Storage Skid ( Chart Industries ) Heating: In order to convert the...

The Altamont landfill gas to liquefied natural gas (LNG) plant is a joint venture between Waste Management and Linde North America. The plant takes the methane gas (bio methane) produced by the landfill and converts it into LNG, which can then be used to power vehicles and heat buildings. This process not only provides a clean, renewable source of energy but also helps reduce greenhouse gas emissions. The Altamont landfill has been producing methane gas since it was opened in the 1960s. Methane gas is a byproduct of the natural decomposition of organic materials, such as food waste and yard waste, that are buried in the landfill. For many years, the methane gas produced by the landfill was simply burned off, which was a waste of a valuable resource and contributed to air pollution. However, in 2009, Waste Management began working with Linde North America to explore ways to convert the methane gas into a usable form of energy. The result of their efforts was the Altamont landfill gas to...

Hydrogen ortho-para conversion is a chemical process in which the spin isomers of hydrogen molecules are converted from ortho-hydrogen (nuclear spins are parallel) to para-hydrogen (nuclear spins are antiparallel) or vice versa. This process occurs due to the energy difference between the two spin isomers, with para-hydrogen being the lower energy state. The conversion of ortho-hydrogen to para-hydrogen occurs spontaneously at low temperatures due to the release of excess energy in the form of electromagnetic radiation. This process is exothermic and can be accelerated by catalysts such as activated carbon, which promotes the relaxation of the ortho-hydrogen molecules to their lower energy para-state. The reverse process of para-hydrogen to ortho-hydrogen conversion requires an input of energy, which can be provided through processes such as microwave radiation or infrared laser excitation. The hydrogen ortho-para conversion process can be described by the following equation: H2 (ortho...

LFG (landfill gas) can be upgraded to produce RNG (renewable natural gas), which is a highly purified form of methane that can be used as a substitute for conventional natural gas. The process of converting LFG to RNG involves several steps, including: Collection : LFG is collected from the landfill using a network of pipes that are buried underground. The gas is typically a mixture of methane (50-60%), carbon dioxide (40-50%), and trace amounts of other gases. Pre-treatment: The collected LFG is first pre-treated to remove any impurities, such as moisture, hydrogen sulfide, and other trace gases. This is typically done using a series of filters and scrubbers. Compression: The pre-treated LFG is then compressed to increase the pressure and reduce the volume of the gas, making it easier to transport. Upgrading: The compressed LFG is then upgraded to produce RNG, which involves removing the carbon dioxide and other impurities from the gas to produce a high-purity form of methane. There a...

Magnetic refrigeration is a cooling technology that uses a magnetic field to transfer heat, as opposed to traditional cooling methods that rely on the compression and expansion of gases. The process relies on the magneto-caloric effect, which is the property of certain materials to heat up when exposed to a magnetic field and cool down when removed from the field. In a magnetic refrigeration system, a magnetic material is placed in a magnetic field and is allowed to heat up. The material is then removed from the magnetic field, causing it to cool down due to the magneto-caloric effect. The cooled material is then used to cool a heat transfer fluid, which in turn cools the surrounding environment. The system typically consists of a series of rotating disks or cylinders that are made up of magnetic material and a heat transfer fluid. The magnetic material is alternately exposed to and removed from the magnetic field, causing it to heat up and cool down. The heat transfer fluid flows thro...

Magnetic refrigeration has the potential to be used for hydrogen liquefaction, as it can provide a highly efficient and environmentally friendly alternative to traditional refrigeration methods. Hydrogen is typically liquefied through a process known as the Joule-Thomson effect, which involves the expansion of compressed hydrogen gas through a valve, causing it to cool and liquefy. However, this process requires a large amount of energy and is not very efficient. Magnetic refrigeration can potentially offer a more efficient and environmentally friendly solution for hydrogen liquefaction. The magneto-caloric effect can be used to cool down hydrogen gas, which can then be compressed to liquefy it. The cooling process would be repeated as necessary to achieve the desired temperature for liquefaction. One of the main advantages of using magnetic refrigeration for hydrogen liquefaction is its high efficiency. The process can provide high levels of cooling with a relatively small amount of e...

Optimizing landfill conditions is an important strategy for increasing the production of landfill gas.

This can be achieved by adding water to the landfill or by covering it to reduce evaporation. Control temperature: The rate of decomposition and gas production in a landfill is also influenced by temperature. The optimal temperature range for landfill gas production is between 35-45°C (95-113°F). To achieve this temperature range, the landfill can be insulated to retain heat or heating systems can be installed to keep the temperature at the desired level. Optimize pH: The pH level in the landfill can also affect the rate of decomposition and gas production. An optim...

Landfill gas is a natural byproduct of the decomposition of organic waste in landfills. It is mainly composed of methane and carbon dioxide, but also contains small amounts of other gases like nitrogen, oxygen, and trace amounts of other gases. To increase the production of landfill gas, there are a few strategies that can be employed: Increase the amount of organic waste in the landfill: The more organic waste there is in the landfill, the more landfill gas will be produced. This can be achieved by diverting more organic waste away from other disposal methods (like incineration or landfilling in a non-gas-producing landfill) and into the gas-producing landfill. Optimize landfill conditions: The decomposition of organic waste is influenced by a variety of factors, including temperature, moisture, and pH. By adjusting these factors to create the ideal conditions for decomposition, the production of landfill gas can be increased. For example, increasing the temperature and moisture conte...

Ionic liquids have unique properties that make them ideal for use as working fluids in hydrogen compression. Ionic liquids are composed of ions, which are electrically charged particles, and are characterized by their high thermal stability, low vapor pressure, and high electrochemical stability. These properties make them suitable for use in hydrogen compression because they can maintain a constant pressure over a wide temperature range, reducing the risk of hydrogen leaks. In an ionic liquid compressor for hydrogen, the ionic liquid is used as the working fluid. The ionic liquid is circulated through a compressor, where it is subjected to high pressure and high temperature. As the ionic liquid is compressed, the hydrogen gas is compressed as well, resulting in an increase in pressure. The ionic liquid works by absorbing the hydrogen gas molecules into its structure, which results in an increase in the ionic liquid's volume. This increased volume causes the ionic liquid to be comp...
