The efficiency of treatment of synthetic and semi-synthetic waste oil-in-water (O/W) emulsions by vacuum evaporation is evaluated. A previous destabilisation/centrifugation stage increases the quality of the final aqueous effluent. However, proper selection of a coagulant salt or flocculant is required. A comparison of laboratory-scale evaporation results and those obtained in an industrial eva...

Drowning is one of the most frequent causes of accidental or suicidal death, and more rarely it is associated with a homicide. Cases of drowning in water or in the sea are common. The authors report an unusual and peculiar case of drowning, that of a woman who accidentally fell inside a collection tank of waste oil of motor vehicles.

Some oil refineries arrange low-fusion-point crude oil storage tanks and ones containing high-fusionpoint crude oil at two diverse locations. Refinery needs different pipeline to transport different fusion point oil, so, to transport diverse fusion point oil it needs two pipelines. Because of the constraints resulted from transporting high-fusion-point oil, to schedule such a system is very har...

Microbial fuel cells (MFCs) represent a novel platform for treating wastewater and at the same time generating electricity. Using Pseudomonas putida (BCRC 1059), a wild-type bacterium, we demonstrated that the refinery wastewater could be treated and also generate electric current in an air-cathode chamber over four-batch cycles for 63 cumulative days. Our study indicated that the oil refinery ...

The vertical motion of air that enhances or restricts the atmospheric turbulence through boundary layer is known as "atmospheric stability", in which any movement components such water vapor, aerosols, etc. are affected by stability. aim this research to test effect stability on amount downward aersols flux at 10um (PM10) emission from stacks Daura refinery, and estimated deposition dust aeroso...

As crude oil price reach a new high, the need for developing alternate fuels has become acute. Alternate fuels should be economically attractive in order to compete with currently used fossil fuels. In this work, biodiesel (ethyl ester) was prepared from waste cooking oil collected from a local restaurant in Halifax, Nova Scotia, Canada. Ethyl alcohol with sodium hydroxide as a catalyst was use...

Sub-critical water (sub-CW) technology was used as a new technology with environmental and financial benefits for the recovery of harmful heavy metal ions Cd (II), Zn (II), Cu (II), Fe (II), Mn (II) and Ni (II) in the waste of Japanese scallop Patinopecten yessoensis. The metals are responsible for environmental problems owing to the large amount of the waste. This study proposes a new method u...

The problem addressed in this work is to develop a comprehensive mathematical programming model for the efficient scheduling of oil-refinery operations. Our approach is first to decompose the overall problem spatially into three domains: the crude-oil unloading and blending, the production unit operations and the product blending and delivery. In particular, the first problem involves the crude...
