Firstly, in my paper, the equipment of batch distillation was used, raw material from the sourse of natural gas which had high quality relatively was chosen to make high purity methanol through analyzing the testing results of three different sources of methanol inland; Secondly, constant-molar-holdup model of batch distillation for high purity methanol was proposed and solved by the two-point implicit combined with component balance calibration. Some kinds of effect factors on recovery fraction of high purity methanol were simulated, such as reflux retio, theoretical plates stages, holdup slop, cut withdrawal, etc. As the simulating results showing, when the composition of raw material was 98%, and the average purity specification of high purity in top of column was above 99.9%, the feasible number of theoretical plates was 35, the reflux retio of product phase and slop cut withdrawal respectively were 5 and 10, and the proportion of the outpu of slop cut withdrawal was 15%. Accordingly, the single recovery fraction of high purity methanol was between 50% and 65%. Thirdly, in order to testify the veracity and reliability of the model mentioned above, the raw material of methanol from natural gas was used to experiment for the process of batch distillation. The experimental result was relatively closed to the simulating result., the scope of error was below 10%, which showed it preferable veracious and feasible that constant-molar-holdup model was used to simulate the process of batch distillation for high purity methnol.
本文首先利用间歇精馏装置，分析国内三种不同甲醇原料气来源的甲醇原料，比较结果，最终选择较优的天然气为原料气的甲醇原料制备高纯甲醇；其次，建立高纯甲醇的间歇精馏恒摩尔持液模型，采用了两点隐含法和组分衡算相结合的方法对该模型进行了求解，模拟分析了影响高纯甲醇收率的各种因素，如回流比、理论板、持液量和前馏分等，计算结果表明：当原料组成为98%，塔顶甲醇产品的平均浓度≥99.9%时，适宜理论板数为35块，产品段回流比R为5，前馏分段回流比R_1为10，前馏分的馏出量控制在15%，所得到高纯甲醇的单程收率在50～65%之间；随后，实验验证了模型的准确性和可靠性，实验结果与模型计算结果比较吻合，误差范围在10%以下，表明本文所建的恒摩尔持液模型用于高纯甲醇的间歇精馏模拟计算具有较好的准确性和可靠性；最后，在实验与模拟结果的基础上，确定了高纯甲醇的最终制备工艺路线：理论板数34块，回流比R为5，前馏分段回流比R_1为10，前馏分的馏出量为15%，最终产品单程收率是57.1%。
