Scrubbing Of Fluorine Gas In Super Phosphate Plant
Fluoride and the Phosphate Connection
Fluoride and the Phosphate Connection ... Fluorosilicic acid is composed of tetrafluorosiliciate gas and other species of fluorine gases captured in pollution scrubbers and concentrated into a 23% solution during wet process phosphate fertilizer manufacture. Generally, the acid is stored in ... plants and mines, experience lung cancer and
Conversion of Moroccan phosphogypsum waste into nano ...
· During this process, the fluorine is distributed between PA, PG cake, and gas. In the presence of silica, hydrofluoric acid (HF) reacts readily to form hexafluorosilicic acid H 2 SiF 6 (FSA) via silicon tetrafluoride SiF 4 (STF) [reaction (5, 6, 7 and 8)].After that these fluorine gases are recovered in an adequate scrubber by using scrubbing liquor.

scrubbing of fluorine gas in super phosphate plant
design of single super phosphate plant . Fluorine gas scrubber design for single super phosphate plant Single Super Phosphate SSP Fertilizer industry is the pioneering fertilizer industry in the country and the first SSP plant is said to have been established by EID Parry in the year 1906 Manufacturing of SSP is based on perhaps the simplest chemical reaction amongst chemical
Triple Superphosphates
plant to plant, depending on a number of factors. The effectiveness of fluorine abatement is determined by: (1) inlet fluorine concentration, (2) outlet or saturated gas temperature, (3) composition and temperature of the scrubbing liquid, (4) scrubber type and transfer units, and (5) effectiveness of entrainment separation.
Mixed Fertilizer Plants
In the ammonium phosphate plant, pass the gas streams from the reactor, granulator, dryer, and cooler through cyclones and scrubbers (using phosphoric acid as the scrubbing liquid) to recover particulates, ammonia, and other materials for recycling. In the nitrophosphate plant, prevent NOx emissions by the addition of urea to the digestion stage.
scrubbing of fluorine gas in super phosphate plant
Super PhosphateTriple Superphosphate Plant. Superphosphate is made by acidifiion of rock phosphate with sulphuric acid Similarly TSP is made by acidifiion of rock phosphate with phosphoric acid In both these processes fluorine is evolved which till recently was creating a lot of pollution problems similar to those in the phosphoric acid industry
design of single super phosphate plant
fluorine gas scrubber design for single super . Single super phosphate plant latest design fluorine emission control system. With our latest emission free pollution control system we guarantee the pollution norms as per guideline of PCB. Process reaction raking part for pollution..
Fluosilicic acid
phosphoric acid manufacturing plants and phosphate fertiliser plants. The limit for fluorine gas emissions is (10g) total fluoride per tonne P 2O 5 feed for existing wet process phosphoric acid process line and lbs for new process line. For phosphate fertiliser plants, the maximum current wastewater effluent limitation is

The venture scrubber is equipped with a tailgas scrubber in the form of a packed tower that is usually followed by an entrainment separator. A modern system can reduce fluorine emission to kg ...
Corporate Social Responsibility – Teesta Agro Industries Ltd
Five stage scrubbers have been installed in the single super phosphate plant to control suspended particulate matter (SPM) and Fluorine gas coming out of the chimney. The sulphur yard is surrounded by a high RCC wall of feet and hydrant line and valves are surrounded throughout the wail and the same line is connected with a highpressure pump for 247 hours to control any fire hazard.
EMISSION FACTORS 7/93
abatement systems in removing fluoride and particulate also varies from plant to plant, depending on a number of factors. The effectiveness of fluorine abatement is determined by the inlet fluorine concentration, outlet or saturated gas temperature, composition and temperature of the scrubbing liquid,
Fluoride Action Network | Fluorine recovery in the ...
The fluorine compounds liberated during the acidulation of phosphate rock in the manufacture of phosphoric acid and fertilizers are now rightly regarded as a menace, and the industry is now obliged to suppress emissions of fluorinecontaining vapours to within very low limits in most parts of the world. As with any pollution control operation, it is highly desirable for the operator of the ...
PRE FEASIBILITY REPORT (PFR)
Phosphate, Acid and dilution liquor react together in the Mixer (Reactor) to produce single Super Phosphate. As a result of reaction, fluorine containing gas is generated and by using a scrubber blower continuously the gases are sucked in closed circuit and sent to gas Scrubbing Section.
Super Phosphate/Triple Superphosphate Plant
With proper controls and recovery systems, it is possible to bring down the fluorinebased gas as follows: The existing super phosphate factories which don not recover fluorides have emissions as high as kg/F/tonne of super phosphate.
