Abstract: Process and apparatus for extraction of oil and hydrocarbons from crushed hydrocarbonaceous solids, such as oil shale, involving the pyrolyzing of the crushed solids with liquid hydrocarbon and syn gas rich in hydrogen and carbon dioxide. Crushed hydrocarbonaceous solids are treated with liquid hydrocarbon and hot syn gas at an elevated temperature in a rotary kiln where the crushed solids are cascaded into the hot syn gas for sufficient time to strip the volatile liquids and gases found in the solids, removing the vaporized liquids, enriched syn gas and spent crushed solids from the kiln, fractionating the vaporized liquids and enriched syn gas into the desired fractions. The enriched syn gas is particularly suited for use in combined-cycle electricity generation and in the preparation of various by-products. The process efficiently recycles heat and energy to reduce harmful atmospheric emissions and reliance on external energy sources.

Abstract: Superabsorbent polymers (SAPs) are used for the containment and treatment of wastewaters. SAPs are mixed with a wastewater in amounts sufficient to absorb substantially all of the wastewater and prevent it from leaving a defined containment area. The water can then be evaporated from the SAP to produce a substantially dry polymer composition containing the SAP and the wastewater contaminants. The dry polymer composition is discarded or, when appropriate, used as a fertilizer for plants. Surprisingly, the SAP reduces the odor associated with ammonia containing wastewaters by binding to the ammonia and reducing the ammonia gas present in the airspace around the wastewater. The evaporation process may be conducted in the presence of a heat exchanger to produce cool, fresh air that is used to cool facilities, particularly animal rearing and production facilities.

The undissolved gaseous byproduct may then be vented. The particulate byproduct may then be separated from the fluid by, for example, a cyclone separator. The separated particulate byproduct may then be flushed from said flow.
