Potential of Using real-time OiW monitoring for control of produced water treatment in offshore oil & gas production
(Corresponding) Zhenyu Y.
Topic:
Water treatment
The produced water has been the largest produced fluid stream at most of the current offshore oil & gas production in North-sea. It is not uncommon that the water cut can reach 90% in many matured production fields. No matter the produced water will be eventually discharged to the ocean, or...Read more

Risk analysis for gas pipelines: A sustainability assessment approach using bow-tie analysis
(Corresponding) Panagopoulos J., Karayannis A., Karayannis P., Gouvalias G.
Topic:
Disaster risk reduction and management
Vast amounts of natural gas (NG) are consumed around the world everyday that are mainly transported and distributed through pipelines. Integrity of these pipelines is of primary interest to NG companies, consultants, governmental agencies, consumers and other stakeholder due to adverse...Read more

Mercury in Eisenia fetida and soil in the vicinity of a natural gas treatment plant in northern Croatia during the last ten years
(Corresponding) Prevendar Crnić A., Zgorelec Ž., Srebočan E., Kisić I.
Topic:
Heavy metals in the environment
In this study total mercury concentrations in earthworms and in different soil types at the same locations from the surroundings of four boreholes were analyzed by ICP-MS method, as a part of a comprehensive monitoring of the eco-system in the vicinity of the natural gas production and treatment...Read more

Microbiological treatment of water by cold plasma at atmospheric pressure
(Corresponding) Anelise C.
Topic:
Water treatment
Ensuring the world's population access to drinking water is one of the millennium's challenges, for although our planet is made up of 70% of water, poor distribution and water quality are problems that concern world leaders, being among the objectives of development 2030 agenda set by the...Read more

Development of a novel GC-APCI-QTOFMS methodology for the determination of more than 300 organic compounds in Asopos river water samples
Panagopoulou E., Nika M., Damalas D., Koulis G., (Corresponding) Thomaidis N.
Topic:
General
The site of interest of this study is Asopos river which is located in Sterea Ellada, north of Athens, and passes through areas where 20% of total Greece industrial production takes place. The extensive installation of industries in the area near the river, and the uncontrolled disposal of...Read more

Gas mixture candidates for SF6 replacement in medium voltage switchgear: Analysis and modeling of the filling episodes
(Corresponding) Espinazo A., Lombraña J., Alonso M., Alonso R., Izcara J., Izagirre J., Pereda-Ayo B.
Topic:
Energy technologies and sustainability
A more environmentally friendly replacement for SF6 must be found for medium voltage switchgear, as a change in European regulations will come into force soon. The mixing process of alternative binary and ternary gas mixtures is studied, which are made up of the hydrofluoroolefin HFO-1336mzz(E) (...Read more

High FAME yield Biodiesel from microalgae through nanocatalytic transesterification process.
Mittal V., (Corresponding) Ghosh U.
Topic:
Environmental biotechnology and bioenergy
Biodiesel production from microalgae is significantly important when reserves of petro-diesel are depleting, and utilization of vegetable oil-based fuel leads to food scarcity. The rapid growth and high lipid content of microalgae is an ideal feedstock for biodiesel production. The use of...Read more

Declassification of drilling waste from oil & gas exploitation through end-of-waste criteria to be used as construction materials
Kazamias G., (Corresponding) Zorpas A.
Topic:
Hazardous waste management
All activities related to Oil & Gas Exploration, Production, Storage and Transportation involve waste generation associated to potential risk to environment. Waste types are related to Exploration and Producing (E&P) activities. These activities are: Drilling operations, Production...Read more

The role of biomass and biowaste in the green energy transition of islands and an introduction to the μgas-to-grid concept
(Corresponding) Vakalis S., Fountoulakis M.
Topic:
Energy technologies and sustainability
The green transition of the energy sector in islands has always been a challenging task. The connectivity of islands with the (mainland) central grid can be problematic, especially when the distance is significant. In such cases, isolated electrical grids need to be developed on the islands, and...Read more

Almost all developed nations have agreed to report their annual greenhouse gas (GHG) emissions, under the UN Framework Climate Change Convention of 1997. But only a few directly measure their landfill gas emissions. Most use the Intergovernmental Panel on Climate Change (IPCC) landfill gas model...Read more
