Show SPRIK inveWrmaT extract oil from shale M. U. Kraui of I'. inland. Ore., inventor of an oil shale retorting tost, which 'ives every indication that li,. Ikis solved one of the jrivut-'st jrivut-'st problems in the development of Die oil shale hiduslry that of tractinu' oil fnun shale on a commercial com-mercial basis. If. .lr. K null's commercial com-mercial tests of the device. 10 be made in the near future, prove as successful as Inborn ory tests, the dinle industry will have a new continuous con-tinuous food retort that should expedite ex-pedite t be development' of western -hale deposits and make the retort-inir retort-inir of the mineral pay in competition competi-tion even with petroleum. AV ith I he interest held by ma ny local citizens in oil shale deposits in this and Uintah counties the Kraul process is nttvaetinic wide attention at-tention here. It is a low tempera lure distihition process where practically prac-tically all of the heal units are conserved, con-served, oil of maximum quality is distilled ;ind a hiirh percentage of extraction secured. AVith this process, oil can be produced pro-duced at a cost of fifty cents a bar rel from Utah shale. Mr. Kraul explained ex-plained Monday morning. "The reduction of oil from shale is comparatively simple. AVith two tin cans, a few feet of pipe and fire, oil can be extracted from shale by boys. But the problem is to extract oil economically enough so that il can compete with tiatural oil. AYe can claim that the manufacture ol oil from shale has been so simplified simpli-fied by the Kraul process that a shale plant can operate profitably at present prices," Mr. Kraul explained. ex-plained. Extreme simplicity and lack of complicated mechanism make it possible, pos-sible, according to Mr. Kraul. te construct a plant, at n cost of $1H per ton daily capacity, or a 500-ton plant for .ffiO.OOO, which is about one-fifth of the cost of building-other building-other plants. The Kraul retort measures twelve feet high, twelve feet long and three sm one-half feet wide. Gas or oil generated from the shale will he used for retorting thi-shale. thi-shale. The firebox between tin? Jshale chambers is twelve inches wide. The blast chamber below the shale and firebox is two feet wide. |
