The present invention describes a method and an automatic system for recovering protein powder meal, crude and pure omega-3 oil and purified distilled water from a mixture of animal tissue processed in a filter-drier-reaction tank. Animal tissue, for example fish, and organic solvent are directly or indirectly fed into the filter-drier-reaction tank. The filter-drier-reaction tank mixes, heats, and separates solid and heavy liquid portions of the mixture, the organic solvents are automatically recycled back in to the system after distillation. The solid portion is retained in the filter-drier-reaction tank and baked. Solid protein powder product (the protein powder meal) is thus recovered.

A method is disclosed for controlling retention time in a reactor, such as an autoclave, having a plurality of compartments separated by dividers with underflow openings. A retention time of the reaction mixture is calculated and compared with an optimal retention time, and the volumes of the reaction mixture in the compartments are adjusted while maintaining the flow rate of the reaction mixture, so as to change the retention time to a value which is closer to the optimal retention time. The reactor may include a level sensor in the last compartment for generating volume data; a control valve for controlling the liquid level in the last compartment; and a controller which receives volume data from the level sensor and controls operation of the control valve.

The present disclosures and inventions relate reactor and method useful in Fischer-Tropsch processes, such as a reactor comprising a first one or more catalyst holding zones, wherein each of the first one or more catalyst holding zones have a first inner surface, wherein the first inner surface defines a first interior space, wherein each of the first one or more catalyst holding zones have a first longitudinal axis, wherein each of the first one or more catalyst holding zones have a first end and a second end, wherein the first inner surface is tapered towards the first longitudinal axis from the first end towards the second end, and wherein each of the first one or more catalyst holding zones are configured to perform an exothermic reaction.

The present disclosure relates to the field of reactor technologies and in particular to a solid-liquid phase reactor for preparing a powder product, which includes a vessel shell, a material-restricting partition net, a solid reactant charge opening, and a reaction solution make-up opening. The material-restricting partition net is disposed in a cavity of the vessel shell and connected to the vessel shell. The material-restricting partition net is enclosed to form a semi-closed material-restricting zone with an upward-facing opening itself or together with an inner wall of a vessel. A frame of the semi-closed material-restricting zone is rigid. The solid reactant charge opening is in communication with the facing-up opening of the semi-closed material-restricting zone, and the reaction solution make-up opening is in communication with an internal space of the semi-closed material-restricting zone.
