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 ...

• Hybrid sulphur cycle for in-situ supply of hydrogen and oxygen to copper plant. Process models a refinery the hybrid in Aspen Plus. Techno-economics green refinery. Potential lower carbon dioxide emissions from production Copper is third-most widely-used metal worldwide. However, processing an energy-intensive process consuming large quantities fossil fuels, both as reducing agent energy whic...

Decrease of fossil fuel dependence and resource saving has become increasingly important in recent years. From this perspective, higher recycling rates for valuable materials (e.g. metals) as well as energy recovery from waste streams could play a significant role substituting for virgin material production and saving fossil resources. This is especially important with respect to residual waste...

Modern decision support systems are forced to deal with perpetual change in their environment: change that includes a high degree of uncertainty over the current state of the plant, effects of actions, accuracy of sensor readings, and consistency of execution of approved procedures by plant operators. In this paper we report on AEGIS (Abnormal Event Guidance and Information System), a large-sca...

7500 tons of municipal solid waste produced in tehran city is land-filled in kahrizak disposalsite. the leachate of the waste has created a lake with 180000m3 in volume. a plant is under construction totreat the leachate. a significant amount of biogas can be produced in anaerobic digestion phase in the treatment plant reactor. the designing process of a power plant in accordance with the produ...

The operational stability and continuity are key production characteristics of actual refinery processing units, which plays important role to safe and efficient production. While few literatures have given a sufficient and comprehensive expression of such characteristics. In view of the problem, this paper discussed refinery operations optimization based on operational stability and continuity...

During the late sixties and seventies the city of Rijeka underwent second rapid industrialization. Few huge plants (new petroleum refinery facilities, power plant, coke plant) were erected in the industrial zone eastwards from the city. As a consequence, high emission levels resulted in elevated ambient air pollution so that the city was one of the most polluted in Croatia during the mid-eighti...

Asthma prevalence in the Cataño Air Basin of Puerto Rico is 27% for children aged 13-14 years and 45% for children aged 5-6 years. There is concern that these rates are related to air pollution. The authors conducted a nested case-control study to evaluate whether proximity to air pollution point sources was associated with increased risk of asthma attacks. For 1997-2001, 1,382 asthma-related m...

â  abstract: in this paper, artificial neural network (ann) was used for modeling the nonlinear structure of a debutanizer column in a refinery gas process plant. the actual input-output data of the system were measured in order to be used for system identification based on root mean square error (rmse) minimization approach. it was shown that the designed recurrent neural network is able to pr...
