Effect of Temperature on Dephosphorization of Hot Metal …

The influence of temperature on the dephosphorization of hot metal at the low temperature range of 1300–1450 °C with the slag of the low basicity (CaO/SiO 2) of about 1.8 is investigated using high-temperature laboratorial experiments.The results show that with increasing temperature, the phosphorus contents in hot metal decrease first and then increase.

Effect of Slag Composition on Dephosphorization and …

The effect of slag composition under M'O (monoxide, M = Fe,Mg) saturation and fully liquid conditions on dephosphorization and slag ability was evaluated in an electric arc furnace (EAF) steelmaking plant operation by considering thermodynamics and phase equilibria. It was confirmed that M'O saturation slag is more favorable for higher dephosphorization than …

Carbon aerogel electrode for excellent dephosphorization …

The dephosphorization rate and energy consumption are shown in Fig. 5f. When the influent pH is 4.4, 6.6, and 7.9, the dephosphorization rate is 1.20, 1.07, and 0.88 μg·min −1 ·cm −2, respectively. Owing to the theoretically lower charge efficiency when removing HPO 4 2−, the energy consumption increases with the increase in pH.

Dephosphorization - an overview | ScienceDirect Topics

Dephosphorization pretreatment or decarburization and heating are completed in one converter. 1. The metal-slag is completely separated after the dephosphorization pretreatment, which is helpful for producing ultralow [P] steel. 2. The high temperature decarburization slags can be directly used in dephosphorization.

Dephosphorization of Metallurgical-Grade Silicon by …

In this work, a dynamic model was established for the dephosphorization of metallurgical grade silicon by levitation refining. Particular emphasis was placed on the transport behavior of phosphorus in the liquid boundary layer, then at the melt surface and finally within the gas phase surrounding the levitated droplet. Within the melt boundary layer, and at the droplet …

Study on the denitrification and dephosphorization of the …

Under this optimum conditions, the denitrification and dephosphorization effect can reach more than 70% when pH value was at 3-9. Dynamics research results showed that the ammonia nitrogen and phosphorus removal progress by chitosan/4A Zeolite/Zr based Zeolite was in accordance could be well described by the pseudo-second-order kinetic model ...

The optimization of the dephosphorization by these strains was also investigated, and the maximum percentages of phosphate removal were recorded at temperature 27-30 °C, initial pH 5.0-6.5, particle size 0.07-0.1 mm, and pulp density of 2-3% (w/v), respectively. The fungus A. niger was found to have good potential for the dephosphorization of ...

Kinetic Model of Hot Metal Dephosphorization by Liquid …

In most cases, hot metal dephosphorization slag is saturated with dicalcium silicate, and the partition ratio of phosphorus between dicalcium silicate and liquid slag is high. These results indicate the important role of solid dicalcium silicate in dephosphorization. In order to understand the reaction kinetics and obtain an optimum treatment ...

Dephosphorylation | NEB

Dephosphorylation. Dephosphorylation is a common step in traditional cloning workflows to ensure that the vector does not re-circularize during ligation. If a vector is linearized by a single restriction enzyme, or has been cut with two enzymes with compatible ends, use of a phosphatase, such as Quick CIP, to remove the 5´ phosphate reduces ...

Dissolution behavior of nutrient elements from …

Dephosphorization slag is primarily composed of CaO–SiO2–FeO–P2O5 slag system. As it contains abundant valuable components, dephosphorization slag is considered a potential material to restore the degraded acid soil. To efficiently supply Ca, Si, Fe, and P elements for acid soil, the dissolution behavior of dephosphorization slag with high P2O5 …
