“…However, Marrone and Hong [138] stated that the transpiring wall reactor has limited usefulness for gasification systems due to adverse effect of dilution on the system's energy balance. On the other hand, Schubert et al [159] used a salt separation vessel which the design is similar to MODAR's reverse flow reactor. The feed inlet and effluent to the reactor are from the top, whereas the brine effluent is from the bottom.…”

“…The top of the reactor is at supercritical and the bottom part is at subcritical temperatures. In contrast to MODAR reactor which acts as both salt separator and reactor, salt separation vessel proposed by Schubert et al [159] is a kind of pretreatment unit before the reactor. Zöhrer et al [141] used this salt separator to perform catalytic gasification and liquefaction of fermentation residue samples.…”

Abstract:The supercritical water gasification process is an alternative to both conventional gasification as well as anaerobic digestion as it does not require drying and the process takes place at much shorter residence times; a few minutes at most. The drastic changes in the thermo-physical properties of water from the liquid state to the supercritical state make it a promising technology for the efficient conversion of wet biomass into a product gas that after upgrading can be used as substitute natural gas. The earliest research goes back as far as the 1970s and since then, supercritical water has been the subject of many research works in the field of thermochemical conversion of wet biomass. This article reviews the state of the art of the supercritical water gasification technology starting from the thermophysical properties of water and the chemistry of reactions to the process challenges of such a biomass based supercritical water gasification process plant.

“…Since processes running under supercritical conditions, are at comparably low temperatures, hence show less tendency towards corrosion (Eliaz et al 2003). But removal of these inorganic compounds from supercritical water is essential since inorganic compounds lead to severe problems like catalyst poisoning, scaling and corrosion (Schubert et al 2010). Supercritical water due to the changes in solvation behavior and solubility for the inorganic compounds offers an option for separation of inorganic compounds in a solid form from the remaining bulk of fluid by the super critical removal process (SCR).…”

'Supercritical fluid' describes a gas or liquid at conditions above its critical point. A greater range of solvent properties can be achieved with Supercritical fluid as a single solvent by careful manipulation of temperature and pressure at the supercritical state. Supercritical fluids are attractive media for several chemical reactions having better control over the reaction rates in different areas of biochemistry, polymer chemistry and environmental science. Supercritical fluid extraction (SFE), a rapid, convenient, efficient, and selective method has been used successfully for the separation of analytes prior to supercritical fluid chromatography (SFC), which is a relatively recent chromatographic technique and is commercially available since 1982. SFC significantly reduces the usage of organic solvents and wastes by using supercritical CO 2 as the mobile phase. The important principles of green chemistry that are applicable to green chromatography includes prevention of waste, use of safer solvents and increasing energy efficiency. All these factors are taken care of in SFC which combines some of the best features of HPLC as well as GC. Analytes that cannot be vaporized for analysis by gas chromatography or have no functional groups for detection by the usual liquid chromatography techniques, can be separated and detected using SFC. By now SFC has been applied to wide variety of materials including natural products, pharmaceuticals, foods, pesticides, herbicides, surfactants, polymers and polymer additives, heavy metals, fossils fuels, petroleum, explosives and propellants. SFC has now become an attractive alternative for chiral drug separation.
