Abstract:
Marine vessel waste treatment installation (1) intended for treatment of dry waste and wet waste. The installation comprises at least one waste receiving unit (2, 3), at least one waste transport means (4), and at least one incinerator unit (6). In order to achieve an efficient waste treatment process, the installation comprises separate waste receiving units (2, 3) for dry waste and wet waste. Dry waste and wet waste are separately fed onto the waste transport means (4) and then mixed by dual waste-feeding screws (41), which feed the waste mixture into the incinerator unit (6).
Abstract:
Methods are disclosed for providing recovered lignin of suitable quantity and quality to provide sufficient heating value to power the generation of supercritical or near critical water without the need for outside sources of energy. Supercritical or near critical water generator devices and systems are also disclosed.
Abstract:
A process for control melting a mixture of coal ash, electric arc furnace dust, recycled glass and additives to create a feedstock. The feedstock is quenched or air dried in a mold to create useful products, such as fracking compounds, abrasives, construction products, building materials, landscaping materials, and the like.

Abstract:
A method is provided for heavy metal stabilisation comprising: mixing waste, comprising heavy metals, with molecular sieve with the proviso that carbon-based molecular sieve is excluded, and clay; and vitrifying the mixture. In particular, a method comprising the steps of: preparing a pre-stabilised mixture by mixing waste, comprising heavy metals, with the molecular sieve, and optionally other chemicals; mixing the pre-stabilised mixture with clay; and vitrifying the obtained mixture is provided. It also provides a product comprising heavy metals that have been stabilised into the structure of the clay-based ceramic matrix, wherein the product is a vitrified product of a mixture of at least waste, comprising heavy metals, molecular sieve (with the proviso that carbon-based molecular sieve is excluded) and clay.
Abstract:
Die Erfindung betrifft ein Verfahren zur Behandlung von Schlamm, wobei dem Schlamm Zusatzstoffe zugesetzt werden, um die Entwässerung des Schlammes zu verbessern und eine thermische Verwertung bzw. Beseitigung des Schlamms zu ermöglichen. Erfindungsgemäss werden als Zusatzstoffe leichte Kunststoffe und/oder Naturfasern in den Schlamm eingebracht.
Abstract:
A coal combustion process is described using coal and processed biomass to reduce adverse by-products in a coal combusting apparatus including the reduction of carbon dioxide by at least 50 volume %. The coal feedstock is selected from coal, a coal substitute processed biomass, or an aggregate blend of coal and processed biomass. The biomass feedstock comprises processed biomass pellets. The total energy density is predetermined and can be similar to the coal component or higher than the coal component. The intracellular salt in the processed biomass is at least 60 wt% less for the processed organic-carbon-containing feedstock used to make the processed biomass pellets than that of the starting un-processed processed organic-carbon-containing feedstock.
Abstract:
An assembly (10) comprising: an engine (12) having a compressor (13) coupled via a shaft (14) to a turbine (15), the engine (12) having an inlet; a heat exchanger (20) having a radiant heat exchanger portion (32) and a convection heat exchanger portion (34); a combustor (40) having a combustor inlet (41) and a combustion products outlet (48); a clean air line (21) having a first section (21a) extending from the engine inlet and through the compressor (13), a second section (21b) extending from the compressor (13) to the heat exchanger (20), a third section (21c) within the heat exchanger (20) extending through the convection heat exchanger portion (34) and then the radiant heat exchanger portion (32), and a fourth section (21 d) extending from the heat exchanger (20) and through the turbine (15); an engine exhaust line (22) extending from the turbine (15) to the combustor inlet (41); a first fuel source (90) in communication with the engine exhaust line (22); and a combustor products line (24) extending from the combustion products outlet (48), through the radiant heat exchanger portion (32) and then the convection heat exchanger portion (34) of the heat exchanger (20) for providing heat energy in use to the third section (21c) of the clean air line (21).
Abstract:
The present invention relates to a waste processing system, comprising: a waste feeding means for feeding waste together with wood chips obtained by cutting wood wastes, under stirring; a waste combustion means, which is installed below the waste feeding means and carbonizes the waste fed from the waste feeing means by applying heat thereto; an exhaust gas purification means, which is installed in communication with the waste combustion means and purifies toxic gases produced from the carbonation process of the waste and toxic gases being introduced into the waste combustion means, thereby discharging them as non-toxic gases; and a fuel production means, which is installed at one side of the waste combustion means and produces fuel by pulverizing and then filtering the carbonized waste from the waste combustion means. Thus, the waste processing system according to the present invention prevents environmental pollution by thermally decomposing those toxic gases produced from waste at high temperatures and also reduces the maintenance cost by recycling the waste as a fuel for combustion.
