This paper addresses the development of pilot scale sustainable technology for microalgae capture of CO2 from power plant flue gas in alkaline solutions to produce biodiesel from algal oil. A combination of computer tools for process simulation, economic evaluation, and environmental impact allow sustainable process assessment. Laboratory scale experiments for growth and culture for algae in la...

We study N -player continuous-time Cournot games in an oligopoly where firms choose production quantities. These are nonzero-sum differential games, whose value functions may be characterized by systems of nonlinear Hamilton-Jacobi partial differential equations. When resources are in finite supply, such as oil, exhaustibility enters as boundary conditions for the PDEs. We analyze the problem w...

The separation of water from oil that is collected in any oil spill recovery operation is a continuing and necessary requirement during every stage of the effort. Its importance is reflected in the cost of transport and storage of large volumes of oily water, the salvage value of separated oil and the added labor costs associated with long-term recovery operations. This paper addresses the effe...

X-ray fluorescence (XRF) spectrometry has been used by the oil industry since the 1950s. XRF can be found supporting activities in exploration, production, research as well as intellectual properties. Traditional applications for XRF were the analysis of single element or a limited range of multiple elements. Today, XRF encompasses high precision full spectral elemental profiles along with high...

Leakage of oil from different oil sections of dumper (cat773) can lead to fire accident and also machine failure if any considerable change in chemical or physical properties of oil takes place which results in loss of property and also life. The system model proposed by us is divided into transmitter and receiver section. The entire control system is based on microcontroller and ZIGBEE techniq...

Crude oil pipeline laid with products pipeline in the same ditch is a new technology to save investment and protect environment. In order to provide reference to construction and operation optimization, the majority of this paper investigates the thermal influential factors affecting the crude oil temperature in double pipelines system using the computational fluid dynamics methodology. A two-d...

Soil and surface water contamination by used lubricating oil is a common occurrence in most developing countries. This has been shown to have harmful effects on the environment and human beings at large. Bioremediation can be an alternative green technology for remediation of such hydrocarbon-contaminated soil. Bioremediation of soil contaminated with 5% and 15% (w/w) used lubricating oil and a...

Joint Inversion of Fracture Model Properties for CO2 Storage Monitoring or Oil Recovery History Matching — For oil recovery or CO2 storage, “reservoirs” are commonly used to designate geological structures where oil can be found or CO2 can be stored. All reservoirs present a heterogeneity in terms of rock type and properties (such as porosity and permeability). In addition, some of these reserv...

––Based on technology and economy, a design of explosion-proof heater of bunched pipeline is mentioned in this paper to solute the problems of the present heater which is used to heat crude oil in winter. The structure and working principle of this new heater are introduced. And the function of the new heater’s swirl plate is described, before the heater power of the new heater is analyzed. The...

A number of studies report the benefit of proper oil spraying in positive-displacement compressors. This work presents a thermodynamic model for simulating sliding-vane air compressors that employ an injection system for the lubricating oil based on both plain orifices and pressure-swirl nozzles to exploit the thermal effect of sprayed oil inside the compression chambers. An experimental campai...
