超声波制备低含油稳定原油乳化液的正交实验
为了利用超声波制备出稳定的低合油原油乳化液,选取乳化剂用量、超声功率、超声作用时间、乳化剂亲水亲油平衡（HLB）值4个影响因素,进行单因素实验和正交实验,筛选超声波制备低含油稳定原油乳化液的最佳条件.根据乳化剂用量单因素实验结果,确定最佳乳化剂用量为0.5％.通过超声功率、超声作用时间和HLB值3个因素的正交实验,进一步优化了制备稳定原油乳化液的条件.实验结果表明,对乳化效果影响大小的因素依次为超声作用时间、超声功率和乳化剂的HLB值;最佳乳化条件为超声功率400 W、超声作用时间10 min、HLB值6、乳化稍用量0.5％,在此最佳条件下可制备出含油率为1％～9％的稳定原油乳化液....
