油砂处理技术发展现状

Status of Oil Sand Treatment Technology

世界范围内油砂的储量较为丰富,其开发利用越来越受到人们的关注。论文介绍了几种油砂处理技术的原理、方法、工艺条件、处理效果和优缺点等,包括热碱水洗涤技术、有机溶剂处理技术、热解干馏技术、微乳液处理技术、超声波处理技术、离子液辅助处理技术及磁化水处理技术等。实际过程中要根据油砂的性质、经济性及对油砂沥青的后续处理要求等选择合适的油砂处理技术。

Oil sand with huge reserves in the world received more and more attention about its exploitation and utilization. Several oil sand treatment techniques about principles, methods, process conditions, treatment effect, advantages and disadvantages, etc., were introduced including hot alkaline separation, organic solvent extraction technology, pyrolysis technique, micro- emulsion technology, ultrasonic separation technology, ionic liquid assist separation technology and technology with magnetic treated process water, etc. In practical process we should select suitable oil sand treatment techniques on the basis of properties of oil sand, economics and the following treatment requirements of tar sand oil.
