Research on Oilfield Produced Water Treatment by Moderately Compressed Exfoliated Graphite Blocks

Abstract:

The objective of this work was to investigate the possibility of oilfield produced water (OPW) treatment by moderately compressed exfoliated graphite (CEG) blocks. The CEG blocks were used as filtration materials to treat OPW of Jianghan Oilfield (Qianjiang, Hubei Province, China). The relationship between density and strength as well as the relationship between density and permeable capability of CEG blocks were studied. Furthermore, the maximum OPW treatment ability of CEG blocks was discussed. The main conclusions are as follows: CEG blocks which are used as filtration materials must have both suitable strength and suitable permeable capability. The effect and efficiency of wastewater treatment can be balanced when the CEG density is nearby 0.025 g/cm³. For OPW of Jianghan Oilfield the maximum treatment ability of CEG which has a density of 0.025g/cm³ and a mass of 0.1673g is more than 20L/g if the filtration rate is ignored.
