摘要： A continuous process for treating coal to form stable coal char by passivating the coal and then rehydrating and cooling the product thereof to prevent spontaneous ignition. The process includes the steps of pyrolyzing the coal to vaporize and remove low end volatile materials and to mobilize high end volatile materials and cooling to demobilize the high end volatile materials within the at least partially collapsed micropores of the coal char to pyrolytically passivate the coal char and form a char having about 14-22 wt % high end volatiles. The pyrolytically passivated coal char is then conveyed to a reaction vessel wherein a process gas having about 3%-21% by volume oxygen flows through the reaction vessel to at least partially fluidize the coal char and oxidatively passivate the coal by chemisorption of oxygen. The passivated coal char is then substantially simultaneously rehydrated and cooled to form a stable coal char having about 5-10 wt % moisture.

摘要： A continuous process for treating a noncaking coal to form stable char. The process includes the sequential steps of drying the coal to remove moisture therefrom and form a dry coal; pyrolyzing the dry coal by progressively heating substantially all of the coal to a temperature sufficient to vaporize and remove low end volatile materials from the coal to form char and sufficient to mobilize at least a portion of high end volatile materials within the char and at least partially collapse micropores within the char. The char is then cooled to a temperature sufficient to demobilize the volatile materials within the at least partially collapsed micropores of the char to pyrolytically passivate the char. The char is then conveyed to a reaction vessel wherein a process gas having about 3%-21% by volume oxygen flows through the reaction vessel to oxidatively passivate the coal by chemisorption of oxygen. The oxidatively passivated char is then substantially simultaneously rehydrated and cooled to form a char having about 5-10 wt % moisture and then conveyed to a final passivation vessel wherein a process gas having about 3%-21% by volume oxygen flows through the vessel to finally passivate the rehydrated char by chemisorption of oxygen.

摘要： An apparatus and method for removing particulate and gaseous pollutants from flue gas. The flue gas enters a presaturation section and is treated with a coarse spray of solution recovered from the system. The saturated gas enters a primary contacting section and is contacted by an ultrafine mist of fresh solution containing a gaseous pollutant absorption agent. The fine mist has an average droplet size of approximately 20 microns. The gas moves to a secondary contacting section where it is contacted by a coarse spray of recirculated solution. If necessary, the gas is demisted. Finally, the gas is discharged into the environment. Usable spent solution is regenerated and reused. Unusable water byproducts containing contaminants are discharged.

摘要： A method and apparatus are provided to control the burning of a lean hydrocarbon containing gas stream under stable conditions using a combination of control logic and hardware. Temperature within the combustor is controlled by using a plurality of staging valves that adjust the amount of oxygen and auxiliary fuel supplied to the combustor burner. Oxygen level is controlled by using actuated butterfly valves that control the flow of primary air to the combustor. The system has pressure control valves for anticipating and compensating for pressure changes and resulting air flow changes as well as temperature monitors and transmitters for anticipating and correcting temperature drops.
