A greener alternative method is proposed for measuring acid values (AV) of fats, oils, and grease (FOG) based on visual titration. Compared with Official Method Cd 3d-63 of the American Oil Chemists' Society (AOCS), this greener alternative method can eliminate the use of toluene, which in turn reduces toxicity and cost. A total of 44 samples of yellow and brown grease with AV ranging from 0.13 to 170.37 (mg KOH) g−1 were titrated using both methods. The alternative titration method can provide accurate and reliable results to determine the AV of FOG by various statistical analyses including repeatability, linear regression, f-test, t-test, and method accuracy calibration with AOCS Cd 3d-63. This low-cost method can be recommended for routine titration in research and development, and in biodiesel plants for most FOG samples. 相似文献

选用合适粒径的氮化铝和氧化铝为混杂导热填料、使用自制的硅烷低聚物为表面处理剂,以溶液插层法对混杂导热填料进行表面改性;然后与甲基苯基硅油混合制备了LED用低热阻导热硅脂。研究了导热填料的种类、粒径、表面处理剂种类及用量对导热硅脂的热导率和黏度的影响。采用LED灯作为实际测试平台表征了导热硅脂的导热性能。结果表明,当填料总质量分数为90.9%,粒径为5μm的氮化铝与粒径为1μm的氧化铝作混合填料且质量比为2.8∶1时,导热硅脂的热导率和黏度有较好的平衡;使用填料质量0.5%的硅烷低聚物对氮化铝和氧化铝混合填料进行表面处理有较好的处理效果;自制10号硅脂样品的黏度(25℃)为174 Pa·s,热阻为1.94℃/W,热导率为4.31 W/m·K。 相似文献

单套甲醇装置投产时变换和甲醇催化剂的还原,因无老系统所依托,只能按流程顺序进行,造成大量的有效气体浪费。同时,还减少5~6d的生产利润。故建议采取统筹考虑的办法,增设制氢装置对催化剂进行预还原。此开车方法,技术上比较成熟,经济效益明显。 相似文献

A steam power plant can work as a dual purpose plant for simultaneous production of steam and elec-trical power. In this paper we seek the optimum integration of a steam power plant as a source and a site utility sys-tem as a sink of steam and power. Estimation for the cogeneration potential prior to the design of a central utility system for site utility systems is vital to the targets for site fuel demand as well as heat and power production. In this regard, a new cogeneration targeting procedure is proposed for integration of a steam power plant and a site utility consisting of a process plant. The new methodology seeks the optimal integration based on a new cogenera-tion targeting scheme. In addition, a modified site utility grand composite curve (SUGCC) diagram is proposed and compared to the original SUGCC. A gas fired steam power plant and a process site utility is considered in a case study. The applicability of the developed procedure is tested against other design methods (STAR? and Thermoflex software) through a case study. The proposed method gives comparable results, and the targeting method is used for optimal integration of steam levels. Identifying optimal conditions of steam levels for integration is important in the design of utility systems, as the selection of steam levels in a steam power plant and site utility for integration greatly influences the potential for cogeneration and energy recovery. The integration of steam levels of the steam power plant and the site utility system in the case study demonstrates the usefulness of the method for reducing the overall energy consumption for the site. 相似文献
