“…As a consequence of the above, it is shown that the use of the plasma torch reactor technology under conditions 30 A, 70% PRPC, and 40 s (TPPT-PC-M12) favors the calcination and conversion of phosphoric rock and increases the concentrations of assimilable phosphorus, solubility index, and total phosphorus, as reported in the previous studies [25,31].…”

Phosphoric rock (PR) is the basic building block to produce animal feed, fertilizers, and industrial phosphates. Global demand for PR is estimated to grow from 207 Mtons in 2018 to 263 Mtons in 2035, of which Colombia contributes approximately 0.06 Mtons per year. A novel technology to carry out calcination is the plasma torch, where the electrical resistivity of the system is increased and ionized gas is produced that can reach temperatures above 10,000 °C, which facilitates the transformation of PR into thermophosphates. Two samples of PR from the region central of the Boyacá department, Colombia, were subjected to calcination through a plasma torch and as a result, showed a maximum concentration of total phosphorus between 27 – 33 % of P2O5 and assimilable phosphorus corresponding to the range 3.0 – 4.8 % of P2O5 respectively. Finally, the energy consumption for calcination is ≤ 1.14 kW-h/Kg, respectively.

With the recent interest in the application of nanoscale metal and metal oxide particles, there is now interest in manufacturing these materials in larger quantities. A number of techniques have evolved for the synthesis of nanopowders. For metal and metal oxide nanoparticles where coalescence is the dominating growth mechanism, concentration and the timetemperature history of the nanoparticles resulting from the reactor design determines the final particle average diameter. In this paper, we present the results of controlled synthesis of alumina nanopowder in a three-jet plasmachemical reactor, where temperature and velocity distributions are controlled by the angle of impingement of the plasma jets. The flow and temperature fields for various impingement angles were measured by an enthalpy probe. The products were characterized by means of electron microscopy, XRD analysis, and BET analysis. The dependences of particle size on the operation parameters (injection velocity of raw material, plasma jet enthalpy, solid/gas mass flow rates ratio, and impingement angle of plasma jets) are discussed. In comparison with the single jet reactor, the novel reactor can increase the production rate several times to manufacture the product with the same required surface area.
