摘要:
针对传统流化床结晶器中工业季戊四醇结晶成长速度低及产品质量和产率不稳定的问题,在新型撞击流结晶器中开展了工业季戊四醇结晶成长速度的研究实验,采用阿伦尼乌斯公式拟合了结晶器中结晶成长速度系数同温度之间的关系,将撞击流结晶器和传统流化床结晶器中工业季戊四醇结晶成长速度进行了对比.研究结果表明:撞击流结晶器中结晶成长速度系数高于流化床中结晶成长速度系数;撞击流结晶器和流化床结晶器中的结晶成长速度系数都随温度的升高而增大;实验结果支持撞击流中强烈的微观混合和压力波动促进结晶成长动力学过程的理论推测.
Abstract:
To solve the problem of the industrialgrade pentaerythritol produced in the traditional FluidizedBed Crystallizer (FBC) with a low crystal growth rate speed and unstable quality and yield, the crystal growth experiments were conducted in an impinging stream crystallizer (ISC). The relationships between the crystal growth rate coefficients in the crystallizers with the temperatures were fitted by Arrhenius equation. The results of the crystal growth rate by an impinging stream crystallizer were compared with those by a fluidizedbed crystallizer. The results show that the crystal growth rate coefficients in ISC are greater than those in FBC, and the crystal growth rate coefficients increase with the increase of temperature for both ISC and FBC. The experimental results also verify the theoretical speculation that the strong micromixing and the pressure fluctuation in the impinging streams crystallizer promote crystal growth kinetics.
