A fractionator of the orthodox gravity type would have to be 700 ft. high, said he, to compete with his trim little machine in efficiency. Heart of the device is a conical coil which is rotated at such speed that the heated contents are squeezed by a force 1,500 times gravity. Outlets at the base of the spinning coil provide very fine separation by density. The super contactor was de-signed to extract from petroleum certain...
