chemistry. The natural development of urine chemistry leading to stone development is urine saturation, urine supersaturation, crystal nucleation, aggregation, the retaining of crystals by the urothelium and the constant progression of the stone on the retained crystals. Supersaturation occurs when the absorption of salt components rises further than the saturation level. The solution is termed to be thermodynamically unstable. Supersaturation leads to nucleation, which is a process that is controlled by the thermodynamic free energy of the solution. The process of nucleation leads to the decrease of excess free energy to a more thermodynamically steady environment. According to Tiselius et al....

chemistry analysis calculations where it has been revealed that operations at 50oC to ensure conversion at 90% and confidence at 95% is best achieved by a tubular reactor design that has a 36.6-liter design to include a diameter of 0.05 m and length of 18.64 m. Additionally, analysis regarding output and costs indicates that the proposed design would increase operational efficiency by 40.63%. Besides that, proposed design has also been shown to be superior to the other reactor designs that include continuous stirred tank reactor and batch reactor. Based on this report, it is proposed that ACC should actively seek to set up a 36.6-liter capacity tubular reactor with 0.05 m by 18.64 m to improve...
