the ATEM mixture is sent to the second stage of neutralization, Phosphate fertilizers – Manufacturing process of Phosphate fertilizers Phosphate rock (PR) is the raw material used in the manufacture of most commercial phosphate fertilizers on the market. A known method of producing ammonium phosphates, including the neutralization of phosphoric acid with gaseous and/or liquid ammonia in a tubular reactor, at a pressure of 3-6 MPa, stirring the mixture in the transport pipeline and feeding the resulting slurry granulation and drying of the product (AS the USSR №1495330, 05, 7/00, 1989). Privacy Policy The method allows to obtain a stable product as the composition and the chemical composition and the process adaptable and reliable. Output - 40 t LFA brand 10,8-52,0. Synthesis / Manufacturing Process of Mono Ammonium Phosphate T he major raw material to all the phosphates is Phosphoric Acid. Mono Sodium Phosphate Monosodium phosphate which is also known as anhydrous monobasic sodium phosphate and sodium di-hydrogen phosphate, is a compound of di-hydrogen phosphate and sodium. The main goal of the pre-neutralization is to form… Already a Chemical Engineering gold or platinum member? The ammoniation is conducted under conditions which form sufficient ammonium polyphosphate to stabilize the solution in the liquid condition. The drawing is a schematic diagram of applicant's process utilizing a spray reactor. The acid temperature was about 230° F. Anhydrous ammonia at a temperature of about 425° was introduced at the bottom of the spray reactor at a flow rate of about 1-2 gpm. The production cost report by Procurement Resource assesses the production of diammonium phosphate from phosphoric acid and ammonia. At a given pressure, finer orifice size produces smaller droplets. The product had the following analysis: The product had a nutrient availability (citrate solubility test) of 100%. A method of producing ammonium phosphates, including the neutralization of phosphoric acid with ammonia at elevated pressure, the mixture in the static mixer and subsequent granulation and drying of the product, characterized in that the neutralization lead in two stages, the first of which serves 80-85% NCRHO4of the total number of the quality and the process is conducted at a pressure of 3.5 to 8 MPa, Applicant has discovered a process of manufacturing ammonium phosphate fertilizer in a single stage reaction vessel which at least partially utilizes the heat of ammoniation to dehydrate the phosphoric acid sufficiently that adequate quantities of polyphosphate are formed in the reaction product. The liquid may be stored and transported without substantial solidification or crystalization so that the product may be subsequently used as an ammonium phosphate fertilizer. The samples produced by Examples I, II and IV were liquid at ambient temperatures and remained liquid at 32° F. At the end of 31/2 weeks testing, samples I II and IV remained liquid at ambient temperatures. Normally the conversion of phosphate to polyphosphate is sufficiently high to provide a stable liquid product, normally in the range of 20% or greater conversion to polyphosphate. Initially, phosphoric acid, gaseous ammonia, and scrubber liquor are directed to the pre-neutralizer reactor. The chemical formula of Ammonium Phosphate is given as (NH4)3PO4. generation, Process for producing ammonium phosphate from ammonia and wet process phosphoric acid, Process for the manufacture of ammonium polyphosphate, Suspension fertilizers and method of producing same, Method of producing ammonium polyphosphate, Process for making stable sludge-free ammonium polyphosphate fertilizer solutions, Method for the continuous preparation of stable aqueous ammonium polyphosphate compositions, Process for production of ammonium polyphosphates, Production of nitrogen-phosphorus compounds, PROCESS FOR PRODUCING HIGH ANALYSIS AMMONIUM POLYPHOSPHATES, MANUFACTURE OF AMMONIUM POLYPHOSPHATE FROM WET PROCESS PHOSPHORIC ACID, Production of ammonium polyphosphates from wet process phosphoric acid, High analysis ammonium pyrophosphate process and product, High-analysis ammonium polyphosphate fertilizer, Production of ammonium phosphates and product thereof, Manufacture of ammoniated superphosphates, <- Previous Patent (Mould with separatin...). Ammonium Phosphate comprises the phosphate salt along with ammonium. Production Of Prom (phosphate Rich Organic Manure) Production of PROM (Phosphate Rich Organic Manure): An Emerging Biofertilizer, Manufacturing of PROM Fertilizer - Toward a Sustainable Agriculture Phosphate rich organic manure is a type of fertilizer used as an alternative to di ammonium phosphate and single super phosphate Phosphorus is required by all plants but is limited in soil, … However, the particle size must be large enough so that the acid falls to the bottom of the reactor and is not unduly entrained in the exhaust gases. The non-granular form is used as a liquid fertiliser. The number given on the 1st stage of phosphoric acid selected from the most appropriate viscosity of the slurry and the required molar relationship, and the high pressure at this stage allows you to more fully absorb the ammonia. Recycling of ammonia by our proposed method is 5% (306 kg) from the input to the process, reducing dust recycling 40% (37 g/m3to 22 g/m3). Typically the temperatures of the ammonia feed would be between about 400° F.-600° F. and the temperature of the acid is between ambient up to boiling. At 155 °C, … The liquid fertilizer can be shipped under ambient conditions to remote sites where it can be mixed to form specific blends of fertilizer. The acid flow rate was about 12 gpm at a pressure of about 60 psi through a standard Tee jet spray nozzle. Decomposes to ammonia and monoammonium phosphate at around 70 °C. 1. The methods and economics of the principal modern manufacturing processes are evaluated and compared. To produce fertilizer in the most usable form, each of the different compounds, ammonium nitrate, potassium chloride, ammonium phosphate, and triple superphosphate are granulated and blended together. The crude phosphoric acid by wet process contains some insoluble, sulfate salts and fluorine. Phosphate additive utilizes nitroammophosphate at weight ratio N:P2O5 equal to 23:21 or 26:13 and phosphate additive melt is preliminarily completely or partly separated from infusible solid phase, after which phosphate additive is introduced in amount 2-6% (as P2O5) of the weight of final product. The temperature of the ammonium polyphosphate solution removed at the base of the vessel was about 310° F. The reaction vessel was operated at about 5 inches of water partial vacuum.
