Novel cascade natural gas liquefaction processes with or without flash gas recovery are proposed to coproduce high‐purity ethane and LNG. The expansion natural gas liquefaction process combining two-stage compression and two-stage expansion is generally utilized for the portable liquefied natural gas system. Two-stage compression includes a low-pressure compressor and a high-pressure compressor. Thus, the compressors’ performance directly affects the natural gas

Natural gas liquefaction technologies

Natural gas liquefaction processes The liquefaction of natural gas using a mixed refrigerant process was first proposed by Kleemenko in 1959 [50]. Mixed refrigerant processes were subsequently adopted for the commercial liquefaction of natural gas nearly 40 years ago. Over 95% of the base-load LNG plants operate on mixed refrigerant processes, with the remaining Based on this concept, the present research proposes a novel system for natural gas liquefaction utilizing pipeline exergy integrated with helium recovery and innovative carbon dioxide capturing and liquefaction. The process was evaluated by energy, exergy, economic, and exergoeconomic analyses. The liquefaction process is the critical segment of the LNG value chain and liquefaction train is is the core of the liquefaction process. A discussion on some aspects of NGL covers the most

A new boil-off gas (BOG) re-liquefaction system for LNG carriers has been proposed to improve the system energy efficiency. Two cascade mixed refrigerant cycles (or dual mixed refrigerant cycle, DMR) are used to provide the cooling capacity for Liquefaction of gases is physical conversion of a gas into a liquid state (condensation). The liquefaction of gases is a complicated process that uses various compressions and expansions to achieve high pressures and very low temperatures, using, for example, turboexpanders. In this paper, an innovative natural gas Pressure Reduction and Liquefaction System (PRLS) is proposed for efficient exergy recovery and liquefied natural gas (LNG) storage. The idea is to recover high-quality exergy of feed gas by producing LNG which makes full use of the thermodynamic exergy generated from the isentropic expansion.

Generally, natural gas is liquefied by rejecting heat to the cold gas that operates in a refrigeration cycle. As the heat duty curve of mixed refrigerant (MR) matches the cooling curve of natural gas in cryogenic heat exchangers, MR based systems are used widely for large scale onshore natural gas liquefaction systems [4]. This paper conducts comparative thermodynamic analysis and performance evaluations of various gas liquefaction configurations. The four most common liquefaction systems (Linde–Hampson, Kapitza, Heylandt, and Claude) were considered. The isothermal and multi-stage isentropic compression processes were evaluated and compared as actual Abstract Hydrogen is emerging as one of the most promising energy carriers for a decarbonised global energy system. Transportation and storage of hydrogen are critical to its large-scale adoption and to these ends liquid hydrogen is being widely considered. The liquefaction and storage processes must, however, be both safe and efficient for liquid hydrogen to be viable as

This system is suitable for natural gas liquefaction by burning a small amount of natural gas to liquefy the rest. In this paper, a heat-driven thermoacoustic Stirling refrigerator with linear motor phase adjuster is proposed.

In contrast, LNG supply chains that include LNG regasification with cryogenic CCS and natural gas liquefaction using proposed systems demonstrate higher exergy efficiency than the conventional method. Siemens‘ Dresser-Rand business recently commissioned an LNGo-HP (high-pressure) micro-scale natural gas liquefaction system for Altagas Ltd. in Dawson Creek, British Columbia, Canada. The modular, expandable LNGo technology enables efficient installation, especially in a demanding environment like Dawson Creek. The Dawson Creek facility, with a

In general, the well gas and associated gas will be purified to a certain standard of pipeline gas which in most countries contains approximately 97% of CH 4. Stirling has developed an integrated gas purification & liquefaction plant together with sister company Hysytech who specializes in gas purification technologies. This change of state takes place in liquefaction plants that include sections for the pre-cooling, extraction and fractionation of heavy component residues. Once liquefied, the gas is stored in large tanks with an efficient thermal insulation system that allows the stored gas to be kept below its evaporation temperature indefinitely.

Liquefaction The dry CO 2 gas passes through a reboiler followed by the CO 2 distillation column. The gas leaving the column at the top contains the inert LNG life cycle The process begins with the pre-treatment of a feedstock of natural gas entering the system to remove impurities such as H 2 S, CO 2, H 2 O, mercury and higher-chained hydrocarbons. Feedstock gas then enters the liquefaction unit where it is cooled to between −145 °C and −163 °C. [12] Although the type or number of heating cycles and/or refrigerants used Gas liquefaction is defined as the process of cooling gas to very low temperatures below its boiling point to convert it into a liquid form for storage and transportation. This involves using industrial scale refrigeration technology to achieve cryogenic temperatures, allowing natural gas to be transported as LNG to regasification plants for distribution. AI generated definition based on

The systems can be designed to handle all boil-off gas, or only the excessive gas not used by the engines (partly liquefaction). Wärtsilä’s Compact Reliq module is our updated offering, translated into a compact and reliable module. The natural gas liquefaction process is the key component in LNG plants in terms of cost, complexity, and operational importance. A good understanding of design and operational requirements and efficiencies of natural gas liquefaction systems is essential for the success of the gas liquefaction plant. There are several licensed natural gas liquefaction processes

BOG Re-liquefaction System Gasified LNG by inevitable heat input from external area is referred to as boil off gas (BOG). BOG is conventionally pressurized Compared to the cascade system, the CO2 rich liquid from phase separator V-1 in the SMR based process is used not for liquefaction but precooling of the compressed retentate gas.

The change of a gaseous substance into a liquid condition is known as liquefaction. Changes in physical circumstances such as temperature, pressure, and volume cause this transformation. Let’s dig deeper into this subject. In recent years, liquefied natural gas (LNG) boil-off gas (BOG) re-liquefaction technologies in LNG ships have been developing rapidly as LNG trade across the sea has become a hot spot in global energy trade. However, there are lots of restrictions on board and BOG re-liquefaction is an energy-intensive industrial process.
