Generally, conversion of microalgae into biofuel involves several processing steps: cultivation, harvesting, dewatering, drying, oil extraction, and biofuel production.
A system boundary of "well to pump" (WTP) is defined and includes sub-process models of the growth, dewatering, thermochemical bio-oil recovery, bio-oil stabilization, conversion to renewable diesel, and transport to the pump.
The periodic pigging of oil and gas pipelines for dewatering, cleaning and inspection has become a standard industry procedure.
Periodically pigging of oil and gas pipelines for dewatering, cleaning and inspecting becomes a standard industry procedure.
This study evaluated the potential of a UV vis absorbance based analytical method to measure the polymer concentration and determine the optimum polymer dose for achieving the best thickening and dewatering performance from oil sands tailings.
The results of the research indicate that thickening and dewatering optimization of oil sands tailings can be achieved by directly measuring the polymer concentration using an in-line UV vis spectrophotometer that can generate real-time information.
The purpose of this note is to predict the dewatering behaviour of treated oil sand tailings over a short-term.
However, the downstream processes for the production of biodiesel, which range from cultivation, harvesting, dewatering, and lipid extraction to oil upgrading, are economically impracticable and can be improved.
Due to the reduction of electricity production, the additional personnel costs, and the increased oil consumption and polymer use in the dewatering phase, a total damage of $150,000 was estimated.
The enhancement of ultrasound irradiation on desalting and dewatering process of LU-NING pipeline oil was studied.
