“…At 30 °C, the B 2 O 3 concentration in the solid decreased from 25.90 to 2.74%. The reason for this is that as the temperature rises to 30 °C, the solubility of Na 2 O 4B 2 O 3 ·4H 2 O increases to 21.9% with that of the NaHCO 3 increasing to 11.1%. − , The significant change in B 2 O 3 concentration is, thus, due to the presence of Na 2 O 4B 2 O 3 ·4H 2 O. Therefore, we took the crystallization temperature in our experimental procedure as 30 °C.…”

This paper proposes a novel method for CO 2 capture, utilization, and sequestration (CCUS) with borax producing disodium octaborate tetrahydrate (Na) equivalent boron compounds and sodium bicarbonate (NaHCO 3 ). We tested the performance of this method experimentally using aqueous ammonium (NH 4 + ) solutions in a pressurized reactor (1 L) continuously purged with pure (99.9%) CO 2 . Experimental parameters were changed as temperature (T), 45−65 °C; solidto-liquid ratio (SLR), 0.69−0.92 g/mL; reaction time (t), 30−60 min; pressure (P), 5−30 bar; NH 3 concentration (AC) 2.82−5.65 M; and steering speed (SS), 500 rpm. The results showed that P and T were highly influential on the performance. The best conditions for CO 2 utilization were found as P = 20 bar; T = 60 °C; SLR = 0.77 g/ml; t = 50 min; and AC = 4.76 M. Per ton of tincal, under these conditions, produced were 0.274 ton of DSOBTH (∼67% B 2 O 3 ), 0.216 ton of NaHCO 3 (∼95% purity), 0.386 ton of avoided boric acid, and 0.417 ton of avoided CO 2 . The total potential added value can be about $1100/ton of tincal.

“…The dried solids were first weighed and then analyzed for B 2 O 3 , − Na (Sherwood 410 Flame photometer), N (Tekmar-Dohrman Apollo 9000 TOC/TN), and C (ELTRA CS 500 carbon sulfur determinator). The NaHCO 3 purity and CO 2 utilization efficiency were then determined from these measurements.…”

“…For samples with vanadate(V) concentrations above 2 × 10 –3 mol·dm –3 , the method using H 2 O 2 was used, while for concentrations below this value, the method using 4-(2-pyridylazo)resorcinol (PAR), forming a colored complex with the tested ions, was applied …”

This article presents the results of equilibrium tests regarding the development of a new waste-free technology for converting ammonium nitrate(V) to potassium nitrate(V) using potassium metavanadate. To establish the best conditions for disposing of postfiltration liquor from the soda-chlorine-saltpeter (SCS) production process, a detailed analysis of the isotherm in the five-component system KNO 3 + NH 4 NO 3 + KVO 3 + NH 4 VO 3 + H 2 O was required. Equilibrium tests were carried out by isothermal saturation of solutions method at temperatures of 293.15 and 313.15 K. The results obtained were used to plot solubility isotherms using the Janecke method. The maximum conversion efficiencies of ammonium nitrate(V) to ammonium metavanadate are 97.53% at T = 293.15 K and 98.69% at T = 313.15 K based on the data for the triple point P 1 . These results, along with literature data, were used to prepare a material balance for the proposed technological concept for the disposal of postfiltration liquor using the SCS method.
