摘要:
The topic of this invention is a procedure for the magnetic separation of yeast biomass from sparkling wine using magnetic particles. The procedure will replace the time-consuming and expensive classic procedure. The classic procedure is based on manual rotation and simultaneous tilting of the bottles from the horizontal to the vertical position with the bottle neck facing down (remuage). For the classic procedure to be completed, approximately 60 days of manual labour are needed to sediment the used yeast biomass in the bottle neck. When the sediment is in the bottle neck, it is removed by freezing and expelled from the bottle during disgorgement. The application of the magnetic particles, which are adsorbed onto the yeast cells needed for the secondary fermentation, and/or on the used yeast biomass after the secondary fermentation, makes the yeast biomass responsive to the magnetic field and thus enables the magnetic separation. The biomass with magnetic particles absorbed onto its surfaces is separated into the bottle neck using an external magnetic field in approximately 15 minutes, whereas the subsequent procedure of purification for the yeast biomass from the wine remains the same as in the classic champagne procedure, including the freezing of the sediment and its expulsion from the bottle during disgorgement.

A continuous online process for rejuvenating whole stream of contaminated lean sulfolane in an extraction system is provided. In particular, a rejuvenator is installed in the solvent circulation loop to remove the contaminants continuously to keep the solvent clean, effective and less corrosive. Specifically, the rejuvenator comprises a high pressure vessel with a removable cover and a round rack with vertical stainless steel tubes fitted in the high pressure vessel. A magnetic bar is placed in each stainless steel tube. A screen cylinder is installed inside the ring of stainless steel tubes. As the contaminated sulfolane is passed through the rejuvenator, the rejuvenator picks up its contaminants. The rejuvenator can be dissembled to remove the contaminants periodically. The rejuvenator is characterized by simple in construction, reliable in operation, and low in operation and maintenance costs. With this rejuvenator, the extraction system can be operated at high efficiency and high capacity without the dreaded corrosion.

A method for suspending or re-suspending magnetically attractable particles is provided. Thereby at least a mixing vessel (10) is provided filled at least partially with a mixture (30) containing magnetically attractable particles (40) at least partially precipitated at the bottom (11) of the mixing vessel (10). An effective magnetic field acting at least in the front end area (3) of the mixing bar (1) is switched on by the magnetic field generating apparatus (4) while the mixing bar (1) is immersed in the mixture (30). Subsequently, the magnetic field is moved away from the bottom (11) of the mixing vessel (10) along with the mixing bar, whereby the movement of the magnetic field along with the mixing bar is carried out such that at least a part of the magnetically attractable particles (40) is raised from the bottom (11) of the mixing vessel (10) and the portion of the particles sticking to the bar is minimized. The magnetic field is switched off in a predefined distance from the bottom which is greater than the distance from the bottom at the time when the magnetic field is switched on. Thereafter, repeated mixing movements of the mixing bar (1) are carried out until the magnetically attractable particles present in the mixture (30) are sufficiently suspended or re-suspended whereby a magnetic field which is switched on does not exist at the front end (3) of the mixing bar (1).

摘要:
Conventional purification apparatuses and operation methods therefor require continuous addition of coagulants as expendables in every operation, and the coagulants are expensive, thereby causing increase in operation cost, and furthermore, the operators have to convey and resupply the coagulant at regular intervals which further increases the operation cost owing to the personnel cost to be increased accordingly. The invention provides a purification apparatus and an operation method therefor, for coagulating and separating particularly the pollutant matter in sea water including oil and the like, which can regenerate and reuse the coagulant within the apparatus, without scarcely resupplying the coagulant and acid/alkali solutions. For disintegrating coagulated flocs and regenerating the coagulant from the sludge, a strong alkali solution and a strong acid solution are required. According to the invention, an alkali water enriched in sodium hydroxide and an acidic aqueous solution containing hydrochloric acid and the like are generated by electrolyzing sea water and collecting sodium ion and chloride ion respectively in the cathode and anode sections, and also by including hydroxide ion and hydrogen ion in sea water; the flocs in the sludge are disintegrated by use of the alkali water; pollutant matter is removed from the aqueous solution subjected to disintegration; and the strongly acidic solution containing hydrochloric acid is added to the acidic solution from which pollutant matter has been separated and removed, and a ferric chloride aqueous solution is generated. The ferric chloride aqueous solution is the coagulant, and thereby the coagulant can be regenerated from the recovered sludge.
