摘要:
A centrifugation device includes a feeding tube defining a longitudinal axis, and a plurality of centrifugal plates extending longitudinally and radially around the feeding tube and rotatable about the longitudinal axis. The centrifugal plates have coarse surfaces coated with one or more layers of polymer material. A centrifugation tank is disposed coaxially with the feeding tube and around the centrifugal plates. A sidewall of the tank is provided with micro/nano filters. Methods for isolation of algal biomass from an algae and aqueous mixture, and extraction of oil from kitchen residue and/or microalgae are also disclosed.
摘要:
A method of producing industrial corn base oil from a raw corn oil byproduct of a corn ethanol production process. The raw corn oil byproduct of the corn ethanol production process is first washed to separate water-soluble products from raw corn oil, then the free fatty acid in the resulting corn oil is neutralized using potassium hydroxide, and a polymeric quaternary biocide is added in a demulsification step, followed by vacuum dehydration of the demulsified corn oil, degumming of the dehydrated corn oil using citric acid, removal of red color from the oil, and final polishing.
摘要:
A method of separating oil from a composition containing an oil and water emulsion, by adding a separation additive which is a fatty ester of alkoxylated glycerol, and performing at least one oil separation step. The method is particularly suitable for separating corn oil from stillage produced in a corn ethanol mill.
摘要:
A process for pre-treatment of a crude tall oil (CTO) for removal of impurities is disclosed. The process comprises a first pre-treatment step involving a CTO wash and a separation of a first oil phase comprising refined CTO and an aqueous phase holding impurities, and a second step involving a separation of a second oil phase from the aqueous phase. A process for refining of crude tall oil (CTO) is also disclosed. The process comprises fractionation under vacuum of a refined CTO into at least one stream of refined tall diesel (RTD) or tall oil fatty acids (TOFA) and at least one stream of resin acid(s) (RA). The stream of RTD or TOFA is deoxygenated forming hydrocarbon compounds in a subsequent step. This invention also relates to a refined tall diesel. Furthermore, a process for the production of a refined tall diesel (RTD) composition, wherein crude sulphate turpentine(s) (CST) is added to the refined tall diesel (RTD) composition, is described.
摘要:
A method of and system for producing oil and valuable byproducts from grains, such as corn, in dry mills are disclosed. The method and system include dewater milling process after fermenting. Further, the method and system are able to produce oil without evaporating. Moreover, the method and system include one or more of the germ processing units, emulsion processing units, fiber processing units, high value protein producing units, and glycerol and inorganic salt producing units, such that high value byproducts are able to be generated.
摘要:
There is disclosed a system and method for processing diesel fuel from petroleum-based waste oil on a small scale compared to conventional methods for re-refining waste oil to a valuable product. In an embodiment, the method comprises dehydrating waste oil to remove water from the waste oil, and operating a thermal reactor to induce thermal pyrolysis of the dehydrated waste oil and convert it into a hydrocarbon vapor phase. The hydrocarbon vapor derived from pyrolysis is condensed and distilled using a distillation tower to produce diesel fuel, heavy liquid hydrocarbon, light liquid hydrocarbon and light hydrocarbon vapor. A filtering step cleans the processed diesel fuel to obtain a clean diesel fuel product.
摘要:
The present invention relates to processes of recovering oil after liquefaction and/or from thin stillage and/or syrup/evaporated centrate from a fermentation product production process by adding a thermostable protease to the whole stillage, thin stillage and/or syrup.
摘要:
This invention is directed to a process for separating a solute from a solute-bearing material. A substantial amount of solute is extracted from the solute-bearing material by contacting particles of the solute-bearing material with globules of an extraction solvent. The particle size of the solute-bearing material and the globule size of the extraction solvent are balanced such that little if any solute or extraction solvent remains in the solute-bearing material.
摘要:
A pod for processing used cooking oils is disclosed that allows a higher energy efficiency of the process and better quality of the final result obtained, in view of different possible uses. This increase in terms of energy efficiency makes it possible to use an apparatus of the domestic appliance type, for processing a given quantity of used cooking oils together with the processing pod according to the invention. Providing the user with the possibility of opting among different combinations of functional substances provided in a main structure and in a secondary structure of the processing pod should, together with the possibility of using an apparatus of domestic use, allow the valorization of used cooking oils directly at the point of consumption.
