Production scheduling defines what products should be produced and what products should be consumed at each point in time over a short period; hence, it defines which run-mode to use and when to perform changeovers to meet the market needs and to satisfy the demand. The study presented in this Article focuses on the scheduling of the loading and unloading of crude oil in intermediate storage ta...

The present study examined the biodegradation rate of benzene vapors in a two phase stirred tank bioreactor by a bacterial consortium obtained from wastewater of an oil industry refinery house. Initially, the ability of the microbial consortium for degrading benzene was evaluated before running the bioreactor. The gaseous samples from inlet and outlet of bioreactor were directly injected into a...

Nowadays, the increasing demand for energy in the world is one of the main concerns for energy supply. In fact, the required energy can be obtained by increasing the production rate of fossil fuels such as oil and natural gas. However, improving the efficiency of the equipment and facilities might have a significant impact on production from hydrocarbon resources. With respect to this subject, ...

Continuous monitoring of Power transformer is very much essential during its operation. Incipient faults inside the tank and winding insulation needs careful attention. Traditional ratio methods and Duval triangle can be employed to diagnose the incipient faults. Many times correct diagnosis due to the borderline problems and the existence of multiple faults may not be possible. Artificial inte...

This paper describes fundamental characteristics of high frequency induction heating applied for Marine Fuel Oil (MFO) recovery system. The system is analyzed for an induction-heating load, related to operating frequency and input power. Frequency domain characteristics of load equivalent circuit parameters in induction heating are investigated to clarify an effective circuit design of the high...

Floor cleaning products on the market usually use synthetic active that can interfere with health and environment. Therefore, highly recommended to substitute natural substances such as essential oils. The by-product of oils is hydrosol which also not safe for This research aims analyze hydrosol's effectiveness an antibacterial get optimal formulation oil in floor products. Kaffir lime leaf oil...

In the future, due to limited resources, a crisis of energy storing molecules (fuels), which are currently produced from crude mineral oil, is expected. One strategy to compensate a part of the oil defi ciency is the production of biodiesel from microalgal lipids. As model microorganism for lipid production microalgae Euglena gracilis was selected and photo-mixotrophic cultivation was performed...

This paper simplifies the energy recovery process in the series hydraulic hybrid bus’ energy regeneration system into a process in which the main axle’s moment of inertia drives the secondary element variable delivery pump/motor and brings hydraulic oil from the oil tank to the accumulator. This process enables braking of the vehicle and also allows recovery of energy to the accumulator. Based ...

as part of the OptiEnR research project, the present paper deals with optimizing the multi-energy district boiler of La Rochelle (France) adding to the plant a controlled thermal storage tank. This plant supplies domestic hot water and heats residential and public buildings, using renewable and fossil resources. Due to the complexity of the district boiler as a whole and the strong interactions...
