DETECTION OF ACCIDENTAL LEAKS IN NATURAL GAS MAIN PIPELINES BY FUZZY LOGIC TOOLS
Environmental Engineering and Management Journal › Vol. 13 › Nr. 6 AbstractPipeline crack-like defects are detected and localized through the monitoring of the transport parameters of the transmissionnetwork. Under SCADA monitoring, accidental gas loss is reduced and the negative environmental impact of the hydrocarbons isavoided. This paper presents a method for the localization of accidental gas leaks, the pressure gradient method combined with afuzzy analysis method, which operates simultaneously both numerical data and lexical arguments in order to accurate...

STUDIES ON DUCTILE - BRITTLE TRANSITION FOR CARBON DIOXIDE PIPELINES
Environmental Engineering and Management Journal › Vol. 13 › Nr. 7 AbstractIn order to diminish the climat changes due to greenhouse gases, the capture from the source, transport and storage of carbondioxide is one of the environmental priorities of the EU until 2050. Transportation of this gas through pipelines (one of thesolutions with most advantages in transport) can be done at ambient temperature only at high pressures, so the carbon dioxide toremain in the supercritical state. In case of underground pipelines, there is a risk of cracking at the wall of th... Autori: Valentin Zichil ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=26447
NEW TOOLS FOR ESTIMATING THE EXTENT OF HAZARDOUS AREAS GENERATED BY GAS LEAK EXPLOSIONS
Environmental Engineering and Management Journal › Vol. 18 › Nr. 4 The current paper is an overview on previous and ongoing research carried out by the authors concerning the use of Computational
Fluid Dynamics for the accurate classification of hazardous Ex areas generated by flammable gases, for the optimization of
computational simulation of air-methane mixture explosions by using ANSYS CFX and FLUENT and for calibrating computational
simulations of gas explosions using the Schlieren effect. These research works containing analytic studies have led to the... Autori: Vlad Mihai Păsculescu ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=27962
QUANTITATIVE WATER MANAGEMENT IN RABAT, SALE AND TIMISOARA DRINKING WATER SYSTEM
Environmental Engineering and Management Journal › Vol. 18 › Nr. 12 For efficient management of the losses of drinking water distribution networks, it is essential to have a precise knowledge of the system and its infrastructures. In this context, our study focused on describing two drinking water distribution networks, from two different countries: Rabat and Sale, Morocco and Timisoara, Romania, for water losses over a period of four and five years, respectively. The work consists of calculating some performance indicators to establish thematic maps using Geogr... Autori: Ziane Imane ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28113 |
