Determination of Behavioral Profile for Storage Facilities

Abstract

Storage buildings are critical buildings in petrochemical facilities. Stored materials may cause considerable hazard in petrochemical industries in the world and Turkey. They generate damaging levels of overpressure and the possibility of human injury/death, building/equipment damage becomes a concern. Predicting the possible consequences of material is important to ensure the safe design of existing and new installations. The predictions through the assessment of such explosions are improved by carrying out experiments and by using theoretical models. Several prediction methods have been developed to estimate the air blast parameters at any given distance from a possible explosion source, assess explosion hazards and to design safer structures. Prediction of the overpressures is typically done using simplified (empirical) models, phenomenological models, and computational fluid dynamics (CFD) models. This study includes a brief discussion on vapor cloud explosions, and the prediction methods. The focus of this paper is on two the most frequently used simplified prediction methods; TNO Multi-energy (ME) model and Baker-Strehlow-Tang (BST) models.

Depolama Tesislerinin Davranış Profillerinin Belirlenmesi

Öz

Depolama tesisleri, petrol işleme tesislerinde depolama amaçlı kullanılan önemli yapılardır. Bu yapılar, dünyada ve Türkiye’de ekonomik değerleri nedeniyle hasarlardan korunmaları gereken yapılardır. Bu yapılarda depolama muhteviyatları nedeniyle meydana gelen patlamalar oldukça ciddi seviyelerde hasara yol açabilmektedir. Bu tip patlamaların sonucunda oluşan yoğun basınç, yapılarda önemli hasarlara yol açabilmektedir. Bu patlamaların neden olabileceği olası sonuçların önceden tahmin edilmesi mevcut ve yeni depolama yapılarının güvenliğinin artırılması açısından önemlidir. Yapılan bu tahminler, çeşitli matematiksel modeller yardımıyla gerçekleştirilir. Patlamaları meydana getiren değişkenlerin tahmini için bir çok hesaplama yöntemi geliştirilmiştir. Böylelikle, patlama hasarını azaltmak ve daha güvenli yapılar inşa etmek mümkün olmaktadır. Bu çalışma kapsamında, depolama yapılarında yapısal davranış tesbiti için, patlama sonucunda meydana gelen hasar tesbiti ve ön belirleme yöntemleri çerçevesinde detaylı bir değerlendirme sunulmaktadır. Çalışmada, meydana gelen hasarın belirlenmesi için kullanılan basitleştirilmiş TNO Çoklu Enerji (Multi Energy – ME) ve Baker-Strehlow-Tang (BST) modelleri karşılaştırılmıştır. Elde edilen sonuçlar detaylı olarak sunulmuştur.
