ALOHA PHAST Software Tools are used realize an modelling scenarios thus effects just get ...
اکسید اتیلن ماده ای بسیار سمی و خطرناک از نظر امکان ایجاد انفجار و آتش سوزی است و واحدهای تولید اکسید اتیلن در میان پرمخاطره ترین واحدهای صنایع پتروشیمی قرار دارند. از این رو پرداختن به ایمنی و مدیریت ریسک این واحدها همواره مورد توجه بوده است. برای مدیریت ریسک واحدهای فرآیندی، علاوه بر محاسبه احتمال رخداد حوادث نامطلوب نیاز به محاسبه شدت تأثیرات و عواقب این حوادث نیز هست. تا بدین وسیله، ریس...
ارزیابی ریسک، شناسایی مخاطرات فرآیندی با استفاده از روشهای سیستماتیک جهت اطمینان از سطح ایمنی واحدهای فرآیندی امری ضروری است. یکی از مراحل افزایش سطح ایمنی در صنایع شیمیایی، ارزیابی ریسک خطراتی مانند رهایش و پخش مواد شیمیایی در محیط زیست است. مدلسازی خطرات موادشیمیایی از جمله نحوه رهایش این مواد، آلودگی محیط زیست در یک واحد فرآیندی از مهمترین مراحل ارزیابی ریسک محسوب میشود. مدلسازی رهایش م...
This systematic review investigated small-group Tier 2 interventions to improve oral language or reading outcomes for children during preschool and early primary school years. Literature published from 2008 was searched 152 papers selected full-text review; 55 studies were included. Three strength of evidence assessment tools identified a shortlist six with relatively strong evidence: (a) Early...
Background and purpose Many efforts have been made to use chemical components as weapons throughout history until the Germans first employed chlorine gas cylinders in April 1915 at Ypres Belgium against French and Canadian soldiers. Leaving 5,000 dead and 15,000 injured, it was the first practical application of chemical agents. The Geneva Protocol in June 1925, which was an attempt to pre...
The present study evaluates the risk of gasoline tank National Iranian Oil Product Distribution Company (NIOPDC) in Sari region using process hazard analysis software tool (PHAST) and according to environmental data unit. consequences different scenarios such as small medium leakage, constant release rate complete rupture were modeled then range each one was obtained intensity radiation or pres...
Background: Nowadays, the reduction of incidents, their effects and their consequences have become one of the priorities of organizations. Despite all the efforts made in various sectors to reduce events, every year, there are many events that threaten industrial societies. In order to mitigate the effects of these incidents, prediction and planning are critical to dealing with them. Therefore,...
Abstract Industrial discharges pose global ecological risks. This study investigates Algeria’s GL1K (gas liquification complex of Skikda) plant’s hazardous effluents. The impact assessment evaluates the environmental repercussions researched facilities, including effects on populations and their way life. Thus, it is possible to stress suggestions improve facility design remove or restrict nega...
