In materials science, liquefaction is a process that generates a liquid from a solid or a gas or that generates a non-liquid phase which behaves in accordance with fluid dynamics It occurs both naturally and artificiallyAs an example of the latter, a "major commercial application of liquefaction is the liquefaction of air to allow separation of the constituents, such as oxygen, nitrogen, and .
Liquefaction technology selection for offshore FLNG projects
The key technical challenges, which influence the liquefaction process and equipment selection for a floating gas liquefaction facility, can be summarised as follows Space and weight requirements Floating systems are space limited, requiring more compact and lighter equipment to fit the deck space
A review on hydrothermal co-liquefaction of biomass ,
Sep 15, 2019· In summary, using biomass model compounds to investigate co-liquefaction effects is an effective way, which allows more explicit studies on the chemical interactions during hydrothermal co-liquefaction process, and is helpful to better understand the underlying mechanisms of co-liquefaction effect on biocrude formation
CO₂ purification and liquefaction | Linde Engineering
Our CO 2 plants are designed for the highest levels of energy efficiency Ease of maintenance and automated operations further reduce operating costs A distributed control system (DCS) or programmable logic controller (PLC) dynamically adjust the process to meet changes in the feed gas composition or plant load
CO 2 liquefaction is an essential process for long-distance ship transportation The conventional CO 2 liquefaction process employs either an external coolant or liquid expansion followed by multistage compression to obtain liquefied CO 2 at low pressure However, these processes consume considerable amounts of energy, which presents an obstacle to commercialization

Coal liquefaction: technically feasible, but the process to synthetic crude is not economic Converting coal to transportation fuel for IC engines does not reduce CO 2 emissions If needed for energy security, milder processes with high coal to oil yields must be demonstrated at commercially relevant scales
The following components, applied and proven in LNG and other industries, comprise the core liquefaction process: The single mixed refrigerant (SMR) liquefaction process is at the heart of the OSMR® process, using proven cold box heat exchangers;
Reason for Discussion of Direct Liquefaction of Coal in Gasifipedia As the following discussion of Direct Coal Liquefaction (DCL) explains, the fundamental process approach of DCL does not involve gasification at all Therefore it would seem to be entirely out of scope of Gasifipedia However, the following considerations require that discussion of DCL be included:
Soil liquefaction occurs when a saturated or partially saturated soil substantially loses strength and stiffness in response to an applied stress such as shaking during an earthquake or other sudden change in stress condition, in which material that is ordinarily a solid behaves like a liqu
liquefaction process, iii) generate valuable LPG product, iv) produce refrigerant make-up (C1, C2, C3) •UpstreamLPG extraction usually based on expander process Can provide ”deep”extraction of C3 and C2 Feedgas need to be recompressed before liquefaction Liquefaction pressure can be high
Process of Liquefaction The Natural Gas that is used to meet power, commercial and domestic needs throughout the world is over 90% pure methane, the lightest occurring hydrocarbon with the lowest carbon footprintAlthough predominantly methane, the “Feed Gas” from the interior of Oman also contains “sour gases” (in Oman mainly carbon .
Carbon dioxide (CO 2) is absorbed and removed from natural gas with an amine absorber (acid gas removal or AGR) and an adsorbent is used to remove water These impure substances are removed so that ice will not form during the subsequent liquefaction process 3 Heavy Hydrocarbon Separation and Liquefaction
