膜分离技术在化工行业中的应用趋势

2014-06-27 20:17:54 杭州沃腾膜工程有限公司 已读

随着膜科学的迅速发展,应用膜分离技术进行化工分离已进入大规模应用阶段。化工产品、原料的纯化、化工废水的处理回用已逐步被人们接受,而 尤以化工废水深度处理回用的发展最为迅速。本文针对膜分离技术在石油化工、化工、农药化工、化肥工业节能减排方面的应用进行了叙述,重点介绍了膜分离 技术进行化工废水处理回用的情况。

膜分离技术在石油化工节能减排中的应用

微滤技术在石油废水处理中的应用

采用南京化工大学膜科学技术研究所生产的0.2μm和0.8μm陶瓷膜进行陆上和海上采油平台的采出水处理研究,经过适当的预处理后取得了较好的效果。悬 浮物含量由73~290mg/L 降至1mg/L以下,油含水量由8~583mg/L降至5mg/L以下。针对膜处理中最为关键的清洗问题,设计了脉冲及预处理工艺,有效地延长了过滤周 期。同时根据油田采出水对膜面的污染特征,确定了B、C两种清洗剂交替使用的清洗方案。并验证了所采用的预处理工艺、清洗工艺、脉冲工艺的可重复性和稳定 性,为工业性放大试验奠定了技术基础。针对低渗透油田注入水而研制的新型含油污水精细过滤装置采用表层过滤技术,用陶瓷微滤膜(无机膜)作滤芯,采取交叉 流过滤方式对含油污水进行精细过滤,对于以小细粒(<8μm)为主的含油污水颗粒去除率达90%以上,精度可达1μm。研制的控制系统作为无机膜含 油污水处理装置的配套装置,实现了对整个过滤过程及脉冲反洗过程的全自动控制。采用絮凝剂絮凝和陶瓷膜微滤的组合工艺处理炼油厂“三泥”水相。研究结果表 明,絮凝处理可明显降低水相的石油类浓度和COD,将絮凝处理与0.2μm氧化锆膜过滤处理相结合,渗透液的石油类浓度和COD 可达到国家排放标准。以絮凝处理后出水的石油类浓度为基准,确定了合适的絮凝剂为3530S,并通过正交试验确定了合适的絮凝处理工艺条件,即絮凝剂70 mg/L,温度为40℃,搅拌90 min,静置时间为1.5 h。絮凝处理能减轻膜污染,增大膜的渗透通量。考察了操作压力和错流速率对渗透液质量和膜渗透通量的影响,确定了合适的操作条件。
