[Excerpt]
The road ahead
India is looking to further develop and harness its various renewable energy sources. Millions of dollars in revenue to India’s oil and gas sector are being lost daily without considering the impact of environmental waste and the cost of lost revenue from the bottom of the barrel. In the effort to become selfsufficient, increased refinery margins alone will not sustain the rising cost of crude refining. Including the installation of the GES to existing refineries and those with failing mechanical filtration could effectively increase India’s energy supply, reduce environmental waste and create more efficiency in crude oil production.
Case studies and economics
Recently, an Indian refinery installed an electrostatic separator in preference to a mechanical filtration unit. The refinery conducted an economic study to evaluate the impact of the change in separation and filtration technologies. Several advantages became evident once the electrostatic separator unit was put on line.

Patent number: 9567056
Abstract: Systems, devices and methods are disclosed for controlling the flow of a fluid over the window of an optical instrument housing in a freestream flow field. For example, the flow upstream of the housing may be split to create a flow region over the window that is conducive to successful operation of the instrument. The flow region may be maintained for various rotations of the housing about yaw, pitch, and roll axes. The disclosed features in some embodiments induce flow regions with reduced spatial and temporal density gradients of the flow over the window.

Abstract: A device for generating a pulsed flow in a channel containing a circulating algal culture can include a plate that is pivotably mounted on the channel and an activator. A pulsed flow is generated in the channel by first positioning the plate to impede the flow of circulating algal culture and then rotating the plate to a submerged position. The pulsed flow can be employed to counteract the negative effects of bio-fouling on algae cultivation equipment. In another arrangement, a device for generating a pulsed flow in a sloped raceway that is in fluid communication with a sump can include a gate. In different embodiments, the gate can operate as a so-called “pinch gate” or as a so-called “overflow gate.” In another aspect, a variable rate pump, such as a centrifugal pump, a screw pump or an airlift pump, is described for establishing a pulsed flow in a channel.

This addition is controlled in response to the growth rate of the algae cells to maintain a substantially same concentration of cells at each location in the EPFR. At all times, the medium provides sufficient nutrients to support growth and maintain a high concentration of algae cells, i.e., at least 0.5 grams per liter of medium, in the EPFR. After the desired level of growth is reached, the algae cells are transferred from the EPFR to a standard plug flow reactor wherein oil production is activated in the algae cells.
