REMEDIATION OF CRUDE OIL POLLUTED SOIL USING TRADITIONAL AND MICROWAVE PYROLYSIS.

尼日利亚蓬勃发展的石油勘探活动不断造成环境污染。超过300万桶原油泄漏到尼日尔三角洲地区。热修复技术是为处理受石油污染的土壤而建立的，但存在能源成本高的问题。本研究的目的是将微波热解应用于污染土壤，并与传统热解方法进行比较。具体目标是优化微波热解的工艺参数，对所释放的油进行表征，并与微波热解的能耗进行比较。特别是，正在确定土壤成分和水分含量对微波热解脱除原油的影响。首次表明，对于富含粘土的土壤，可以实现与传统热解相当的除油效果。

Booming oil exploration activities in Nigeria have constantly caused environmental pollution. Over three million barrels of crude oil spilled into the Niger Delta region. Thermal remediation technologies are established for treating oil contaminated soil but suffer from high energy costs. The aim of the research is to applying microwave pyrolysis for contaminated soils and draw comparisons with traditional pyrolysis methods. The specific objectives are to optimise processing parameters in microwave pyrolysis, to characterise the oils released and compare the energy consumption with microwave pyrolysis. In particular, the impact of soil composition and moisture content on the removal of crude oil in microwave pyrolysis are being determined. It has been shown for the first time that oil removal comparable to traditional pyrolysis can be achieved for soils rich in clay.
