Sentetik baca gazıyla doyurulmuş propiyonik asit varlığında kolemanitin çözünmesinde çözeltiye geçen 〖Ca〗^(+2)’nın çözünme davranışı ve kinetik incelenmesi

Abstract

Kolemanit (〖2CaO.3B〗_2 O_3.5H_2 O) bir kalsiyum borat mineralidir ve endüstriyel borik asit üretiminin temel maddesi olarak ifade edilebilir. Borik asit, kolemanit cevherinin asidik çözelti ve gazlarda çözülmesiyle elde edilen en önemli hammaddelerden biridir. Kolemanitin sentetik baca gazıyla doyurulmuş propiyonik asit çözeltisinde çözeltiye geçen 〖Ca〗^(2+)’un çözünme davranışı ve kinetiği incelenmiştir. Bu kapsamda; tane boyutu, reaksiyon sıcaklığı, asit konsantrasyonu, katı-sıvı oranı ve sentetik baca gazı debisi parametrelerinin etkisi araştırılmıştır. Deneysel verilere göre çözeltiye geçen 〖Ca〗^(2+) miktarı; reaksiyon sıcaklığı, asit konsantrasyonu ve gaz debisinin artması ile katı sıvı oranı ve tane boyutunun azalmasıyla arttığı gözlemlenmiştir. Deneysel veriler Statistica paket programı vasıtasıyla homojen ve hetorojen modellerine göre analiz edilmiş ve çözeltiye geçen 〖Ca〗^(2+)’un çözünmesi “Avrami modeline” uyduğu belirlenmiştir. Aktivasyon enerjisi (E) 〖26.83 kJ.mol〗^(-1) ve Arrhenius sabiti (A) 〖8.9*10〗^3 olarak hesaplanmıştır.

Dissolution behavior and kinetic investigation of 〖Ca〗^(2+) in the dissolution of colemanite in propionic acid presence saturated with synthetic flue gas

Abstract

Colemanite (〖2CaO.3B〗_2 O_3.5H_2 O) is a calcium borate mineral and can be expressed as the primary material of industrial production of boric acid. Boric acid is one of the most essential raw materials obtained by solving colemanite ore in acidic solutions and gases. The dissolution behavior and kinetics of 〖Ca〗^(2+) in a solution of colemanite in a propionic acid solution saturated with synthetic flue gas were examined. In this context; the effects of particle size, reaction temperature, acid concentration, solid-liquid ratio and synthetic flue gas flow rate parameters were investigated. According to the experimental data, it was observed that the amount of 〖Ca〗^(2+) passing to the solution increased with the increase of the reaction temperature, acid concentration and gas flow rate, and with the decrease in solid-liquid ratio and grain size. Experimental results were analyzed by homogeneous and heterogeneous models using the Statistica package program, and it was determined that the dissolution of 〖Ca〗^(2+) in solution complies with the “Avrami” model. The activation energy (E) was found as 〖26.83 kJ.mol〗^(-1) and the Arrhenius constant (A) was found as 〖8.9*10〗^3.
