    Abstract: A method and apparatus for enzymatic hydrolysis where a plant based feed is hydrolysed using an enzyme to form a hydrolysed product. An additive for preventing enzyme adsorption is fed to an enzymatic hydrolysis stage, the plant based feed, the hydrolysed product, a starting material, and/or a plant based material formed from the starting material. The hydrolysed product is supplied from the enzymatic hydrolysis stage to a first solid-liquid separation stage where a lignin fraction comprising the additive and a liquid composition comprising the enzyme are separated. The liquid composition is mixed with the plant based material in a mixing stage, forming a mixture. A solid and liquid fraction are separated from the mixture in a second solid-liquid separation stage. At least part of the solid fraction comprising the enzyme is fed as the plant based feed to the enzymatic hydrolysis stage.

    Abstract: The invention relates to a method and a device for cleaning contaminated used oil, in which starting material is heated to the gas phase and the resultant vapor is rectified, with purified oil being removed as condensate from a drain in a rectification column. This enables efficient operation even in the smallest of systems, such that a compact system configuration and thus in particular mobile use by a container structure is made possible. The invention also reduces the cost required for servicing. The used oil is subjected to an evaporation process by at least indirectly placing the starting material in contact with a melting bath, the melting temperature of which is above the evaporation temperature but below the ignition temperature of the used oil, and by rectifying the vapor in the rectification column.

    Abstract: A Salinity Gradient Solar Pond has saturated salt water in the bottom of the pond and nearly fresh water at the top, with a gradient zone between the top and bottom. Due to this salinity stratification the upward diffusion of salt is a natural consequence in SGSP's. This upward diffusion of salt has been found to range 60-80 gr/m2/day (Tabor, H.; Solar Ponds, Solar Energy, v. 27 (3), pp. 181-194, 1981 and v. 30 (1), pp. 85-86, 1983). Controlling the salinity gradient in SGSP systems is vital to their reliable operation. One proposed method for controlling the salinity gradient is the so called “Falling Pond” method, where water is extracted from the saturated bottom layer by some means and returned to the nearly fresh upper layer. This action creates a downward velocity in the pond's layers which can be matched to counter the upward diffusion of salt, thereby maintaining the pond's gradient stationary in space.

    Abstract: Systems and methods for disposing of produced water as steam released into the atmosphere. After wastewater is prepared for disposal by suitable filtering and/or treatment, it flows into a preheating tank where it is heated prior to disposal by liquid filled preheating coils extending from the heating tank which are heated by burner boxes. From the preheating tank, the preheated water flows into evaporation coils, where it is heated above boiling and released as steam. Water flowing into the tank passes adjacent the evaporation and preheating coils near the burner boxes. The preheating coils may contain antifreeze which can be circulated to prevent freezing of the preheat tank when not in use or to maintain the temperature of the preheat tank. The system may be moved with the preheat tank filled with preheated water to facilitate the use another location.

    Abstract: An objective of the present invention is, in refining a metal or a semiconductor melt, without impairing refining efficiency, to alleviate wear and tear commensurate with unevenness in a crucible caused by instability in melt flow, and to allow safe operation over long periods of time such that leakages from the crucible do not occur. Provided is a metal or semiconductor melt refining method, in which, by using an AC resistance heating heater as a crucible heating method, the melt is heat retained and mixed by a rotating magnetic field which is generated by the resistance heating heater. The metal or semiconductor melt refinement method and a vacuum refinement device which is optimal for the refinement method are characterized in that, in order that a fluid instability does not occur in the boundary between the melt and the bottom face of the crucible when the melt is rotated by the rotating magnetic field, with a kinematic viscosity coefficient of the melt designated ν (m2/sec), the radius of the fluid surface of the melt designated R (m), and the rotational angular velocity of the melt designated Ω (rad/sec), the operation is carried out such that the value of a Reynolds number (Re) which is defined as Re=R×(Ω/ν)̂(1/2) does not exceed 600.
