| 20120004389 | METHOD FOR EXTRACTING PROPOLIS USING FAR-INFRARED RAYS FROM EARTHENWARE - A method for extracting propolis by using far infrared ray from pottery. The method for extracting propolis by using far infrared ray from pottery makes it possible to prohibit the growth of microorganism by way of far infrared ray by using pottery which emits far infrared ray and has a construction that inside and outside air can exchange while increasing a storage and seasoning effect. Aldehyde contained in alcohol is naturally radiated with the help of air circulation and preventing oxidation decay and shortening an extraction period of propolis. | 01-05-2012 |

| 20120123087 | METHOD FOR PRODUCING CRUDE TALL OIL BY SOAP WASHING WITH CALCIUM CARBONATE REMOVAL - A method for producing crude tall oil from black liquor soap while removing calcium carbonate and lignates is disclosed. Black liquor soap is first combined with an alkaline ash medium having a lower concentration of lignates and inorganic solids than the black liquor soap, to form washed tall oil soap, fortified brine, lignates, and calcium carbonate. The washed tall oil soap is then separated from the fortified brine, lignates, and calcium carbonate, by centrifugation, decantation, filtration, settling, or a combination of these techniques. Acidification of the washed tall oil soap gives crude tall oil and a spent acid mixture. The crude tall oil is separated from the spent acid. The spent acid is made alkaline, and at least a portion of it is returned for use as alkaline wash medium. The method avoids accumulation of calcium sulfate in acidulation units. | 05-17-2012 |
