[0132] Preparation of sludge / emulsion for subsequent removal of bound and free water
[0133] A predetermined amount of internal sludge is prepared with viscous / non-viscous hydrocarbon water, for understanding the sludge, and also for subsequent removal of all bound water therefrom. Therefore, if present, weighed water, hydrocarbons and sodium lauryl sulfate as an emulsifier were mixed and stirred using a high-speed shear mixer at 10,000 rpm for 1 minute and performed 5 times while ensuring that the temperature of the mixed material was insulated...

[0136] Pretreatment of incoming sludge / emulsion using a centrifuge
[0137] The purpose was to determine the degree of bound water present in the incoming sludge, thereby separating it into sludge with bound water and waste oil by centrifuge. Furthermore, the aim was to establish the recovery of value-added marketable hydrocarbons with a batch centrifuge alone; it was possible to remove a part of the water present and also reduce the amount of sludge, which required further treatment. Therefore, the sludge prepared in-house and the lagoon sludge procured from India's Oil and Natural Gas Corporation (ONGC) were treated in a batch centrifuge at 4,500 and 21,853 RCF with different residence times to separate and weigh the fractions after that, The centrifuged material is then mass balanced. In addition, the moisture content of these fractions was evaluated by the BTX method, followed by the ash content by heating in a muffle furnace, followed by evaluation of the calorific value...

[0168] Effect of using xylene as solvent on sludge with bound water
[0169] The effect of releasing bound water from sludge over time was studied by reducing the viscosity of the sludge by adding different amounts of low-viscosity solvents, such as xylene, at room temperature and elevated temperature. In addition, it was discovered how water is simply captured by hydrocarbons. Therefore, about 58 wt.% and 200 wt.% of xylene were added to viscous furnace oil sludge, which did not contain internally produced sodium lauryl sulfate, but had 50 wt.% bound water. Alternatively, about 58 wt.% and 200 wt.% xylenes were added to viscous furnace oil sludge with 20.47 wt.% bound water and 3.74 wt.% sodium lauryl sulfate, the sludge was Extracted from sludge with 47.5 wt.% water and 2.51 wt.% sodium lauryl sulfate inside by centrifugation at 21,893 RCF for 10 minutes. Additionally, 58wt.% and 200wt.% of xylene were added to viscous ONGC sludge with 42.21wt.% bound water and 8.61wt.% as...
