| The ecologically acceptable technology for processing large particle shale includes the retorting in a thin bed, the use of recycle heat carrier heated in heat exchangers, semicoke deep gasification in the lower part of the retort, separate take off of oil vapours and gasification gases, and also a cleaning process for desulfurization of the retort gas and flue gases coming from the burners of heat exchangers. |
