摘要
采用高效波形塔板对传统的尿素合成塔进行改造 ,加强了塔内的传热与传质 ,利用原合成塔下部空间 ,增加了塔板数目 ,使物料在全塔的停留时间分布更理想 ,反应更充分 ,提高了合成塔的反应物转化率。改造结果表明 ,在其它工况不变的条件下 ,塔内CO2 转化率提高了 2 % ,每小时可节约中压蒸汽约 5t。
In traditional urea reactors, the rate of CO 2 conversion is always on the low side and the MS consumption is on the high side because the problems of transfer in the reactors are used to be omitted during the design of reactors. In order to increase the rate of CO 2 conversion in the reactor, the waveform trays are adopted to intensify the effect of transfer and the number of trays is increased to extend the residence time of reactants relatively. The effect of alteration show that the percentage of CO 2 conversion increases 2% and the consumption of MS is saved 5?t per hour.
