Increasing worldwide energy demand requires the replacement of fossil fuel sources with clean and alternative ones to limit the chances of a climate collapse. In this scenario, natural gas supplies approximately 30% of total energy demand and is…
Natural gas liquefaction allows to transport this energy vector over long distances from stranded reserves to the market. Pure Refrigerant Cascade processes will be responsible for more than 105 mtpa of the LNG base-load production by 2021. Classical…
It is preferable to transport or store natural gas (NG) in a liquid state, as liquefied natural gas (LNG). In recent decades, a variety of natural gas liquefaction processes (NGLPs) using mixed refrigerants (MRs) with different configurations have…
A novel concept for energy integration across the liquefied natural gas (LNG) supply chain is proposed by using liquid air as a medium for recycling cold energy. This allows the natural gas liquefaction and LNG regasification stages to be integrated…
CO2 replacement is considered as a promising method for the simultaneous development of natural gas hydrate and CO2 sequestration. The addition of small molecular gases, such as N2 and H2, into the injected gas can increase the gas recovery ratio and…
Coil-wound heat exchangers (CWHEs) have been widely used in natural gas liquefaction plants nowadays. But few studies on the condensation heat transfer and frictional pressure drop of mixed hydrocarbon refrigerants inside the tubes of CWHEs have been…
Selection of mixed refrigerant has a significant impact on the performance of the single mixed refrigerant process for natural gas liquefaction. However, current studies mainly focus on optimizing the fraction of the mixed refrigerant with pre-fixed…
Multi-component refrigerant compression refrigeration cycles have a high coefficient of performance and difficult controllability. In these systems, it is not easily possible to keep the ratio of stream compositions constant in the event of a leak.…
Natural gas (NG) fields of low pressure and small reserve are usually located remotely and dispersedly in China, for which pipeline transport in gaseous state is not economic. As a result, liquefying natural gas with small-scale liquefiers is a more…
Taking advantage of the refrigerating effect in the expansion at an appropriate temperature, a fraction of high-pressure natural gas transported by pipelines could be liquefied in a city gate station through a well-organized pressure reducing process…
