Johnny and Andy are best friends. Both he and she are desperately fighting against poverty and crime in a world that denies them their dream. They dream of being artists. The only outlet they have is spray-art. At night they secretly transform their cold surroundings into a riot of colour and imagination. Johnny finds a voluptuous young woman and falls in love. Soon he finds himself enslaved by drugs, sex and violence. He is at Hell's gate, immersed in hopelessness and near death. An evil crime-boss demands that Johnny does as he commands. When Andy's life is threatened, Johnny comes alive, fighting to regain his pride, his dreams, his friend. Caught between the worlds of truth and deception, where few survive, Johnny is set up in a Double Cross

Fluoride removal from wet-process phosphoric acid reactor gases by John M Craig( Book )
1 edition published in 1970 in English and held by 1 WorldCat member library worldwide
Due, in part, to the growth of the phosphate fertilizer industry, fluoride pollution of the air has become an area of major concern. Since the state of Florida is the center of this industry in the United States, air pollution from the phosphate fertilizer industry is a major problem in certain areas of the state. Fluoride air pollution is a matter of great concern since even at very low levels it is known to produce detrimental effects on vegetation and animals. Phosphate fertilizer manufacturing complexes normal I3' have acid plants associated with them which produce the acid necessary to convert the highly insoluble fluorapatite in phosphate rock to a more readily available form of a nutrient phosphate. One of the most common methods of producing fertilizer grade phosphoric acid is via the wet-process phosphoric acid process. In this process, the reaction between the phosphate rock, sulfuric acid, and recycled weak phosphoric acid releases fluoride gases which may be harmful to plants and animals if not closely controlled. With this in mind, a research project was initiated to study the effects of operating variables upon certain types of air cleaning equipment and the efficiency of fluoride removal from wet-process phosphoric acid reactor gases. For this study, a portable pilot plant was construct ed on two semi- trailers, taken to a 650 tons/day wetprocess phosphoric acid plant, and connected into the center compartment of the reactor tank. The air cleaning equipment used in this study included a 2600 cfm capacity cyclonic spray chamber, a 2600 cfm capacity venturi-cyclonic demister scrubber, a 350 cfm capacity baffle plate impingement column, and a 1000 cfm capacity variable throat venturi. The effects of liquid and gas flow rates and type of scrubbing liquid upon fluoride removal efficiency were studied. The types of scrubbing liquid used -were well water and gypsum pond water. In the case of scrubbing with well water, fluoride removal efficiencies of 63.2 to 96.1 percent, for less than 1.5 inches of H?, and for an energy input of less than 0,7 horsepower/1 0C0 std cfm, are possible using the cyclonic spray chamber. Efficiencies of 88.3 to 99.5 percent, for less than 15 inches of H^O, and for an energy input of less than 3.7 horsepower /1 000 std cfm, are possible using the venturi-cyclonic demister scrubber. Efficiencies of 90.1 to 99.0 percent, for less than 8.5 inches of I^UO pressure drop, and for an energy input of less than 1.0 horsepower/1000 std cfm, are possible using the baffle plate impingement column. Efficiencies of 92.9 to 97.8 percent, for less than 40.0 inches of FUO pressure drop, and for an energy input of less than 4.3 horsepower/1000 std cfm, are possible using the variable throat venturi. In all instances, scrubbing with gypsum pond water produced lower removal efficiencies than scrubbing with well water at approximately the same pressure drops and energy requirements. The fluoride removal efficiencies developed by the equipment studied were not sufficiently high to meet the requirements necessary for emission control from this process. Two- stage scrubber installations are required if the fluorides from the reactor are to be brought under control. Since two -stage scrubber installations are necessary, gypsum pond water would be the preferable scrubbing liquid because the use of this liquid will not disturb the existing water balance established in the process
