hazard evaluation of gas condensate stabilization and dehydration unit of parsian gas refinery using hazop procedures
شناسایی مخاطرات در واحد 400 پالایشگاه گاز پارسیان. در این پروزه با بکارگیری از تکنیک hazop به شناسا یی مخاطرات ، انحرافات ممکن و در صورت لزوم ارایه راهکارهای مناسب جهت افزایش ایمنی فرا یند پرداخته میگردد. شرایط عملیاتی مخاطره آمیز نظیر فشار و دمای بالا و وجود ترکیبات مختلف سمی و قابل انفجار در واحدهای پالایش گاز، ضرورت توجه به موارد ایمنی در این چنین واحدهایی را مشخص می سازد. مطالعه hazop یک ر...
Determination of legal responsibility in iatrogenic tracheal and laryngeal stenosis.
OBJECTIVES/HYPOTHESIS Laryngotracheal stenosis usually occurs as a result of injury from endotracheal intubation or tracheostomy placement. With an estimated incidence of 1% to 22% after these procedures, chronic sequelae ranging from discomfort to devastating effects on quality of life, and even death, make this complication a potential litigation target. We examined federal and state court re...
متن کاملThe Role of Tracheal Stenting As an Alternative Treatment in Cicatricial and Non-Operable Tracheal Stenosis
Introduction: Tracheal stenosis is normally caused by trauma, infection, benign and malignant tumors, prolonged intubation or tracheostomy. The best treatment for tracheal stenosis is resection and anastomosis of trachea. Yet the major surgical complication of tracheal surgery is postoperative stenosis. The goal of this paper is to study the result of tracheal stenting as a replacement therap...
متن کاملFlow-volume loops: clinical correlation.
Flow volume loops are an essential part of spirometry testing. Their appearance can give information that can be helpful in the differential diagnosis of a patient's clinical condition. We present two clinical scenarios in which careful evaluation of the flow-volume loop gives an insight into the cause of the disease process.
متن کاملTracheal stenosis: a flow dynamics study.
Patients referred for treatment of tracheal stenosis typically are asymptomatic until critical narrowing of the airway occurs, which then requires immediate intervention. To understand how tracheal stenosis affects local pressure drops and explore how a dramatic increase in pressure drop could possibly be detected at an early stage, a computational fluid dynamics (CFD) study was undertaken. We ...
