of course, a very slow method. Recently, the bleaching of oils by means of ultra-violet rays has attracted some attention. Cotton Oil Refining. The arrangement of a typical refinery for treating cotton-seed oil is reproduced in Fig. 66. The oil in this case is fir.st heated by steam in a mixing tank A until it reaches a temperature of about 140° F. Thereafter the oil is violently agitated by means of compressed air. the temperature, meanwhile, being kept as near 140° F. as possible. During the ...agitation cau.stic soda solution from the tanks C, D, is run into the mixing tank. As this solution, being heavier than the oil. tends to sink to the foot, care is necessary if it is to be brought properly into intimate contact with the oil. This is secured by distributing the solution evenly over the surface of the oil, and by the vigorous agitation to which the contents of the mixing tank are subjected. When it has been ascertained by testing samples that sufficient caustic soda has beg added to neutralise the acid reaction of the oil, the charge is allowed to standand settle in the mixing tanly The settling is usually sufficiently complete at the end of about twelve hours to permit the clear supernatant oil to be drawn off and passed into the washing tank H.
