Abstract:

A large amount of oily sludge will be produced during crude oil production and transportation. Traditional methods for treatment of oily sludge have the disadvantages of low recovery efficiency and risk of secondary pollution. The supercritical water gasification of oily sludge for hydrogen energy recovery is of great significance for the efficient treatment and utilization of oily sludge. In this study, a uniform design method was used to investigate the relationship between the reaction temperature, reaction pressure, reaction time, material ratio and the hydrogen production, and the empirical formula was fitted by applying the reaction results. The influence of reaction parameters of supercritical water on hydrogen production from oily sludge was analyzed. The results showed that the multivariate linear fitting through uniform design had good feasibility in oily sludge gasification experiments. The fitted empirical formula gained good predictability. The hydrogen production per unit sludge was positively related with the reaction temperature and the reaction time, but had a negative correlation with the material ratio. With the increase of pressure, the hydrogen production per unit sludge increased first and then decreased. In the conditions of reaction parameters of 544℃, 2.2MPa, 150min, and 10%, respectively, the maximum hydrogen production per unit sludge achieved was 5.92mmol/g.

摘要:

在原油采输过程中会产生大量含油污泥,传统处理方式存在回收效率低、环境二次污染等弊端,应用超临界水气化含油污泥进行氢能回收,对含油污泥进行高效处理和利用具有重要意义。本文应用均匀设计方法研究超临界水的反应温度、反应压力、反应时间和物料比与最终单位污泥产氢量之间的关系,并通过反应结果拟合出它们之间的经验公式,分析超临界水反应参数对含油污泥气化制氢影响规律。结果表明,通过均匀设计进行多元线性拟合在含油污泥气化实验中具有较好的可行性,拟合出的经验公式具有良好的预测性,单位污泥产氢量与反应温度、反应时间呈正相关,与物料比呈负相关,伴随压力的增加单位污泥产氢量先增加后减小。在反应参数为544℃、2.2MPa、150min、10%下,单位污泥产氢量最高为5.92mmol/g。
