Abstract

There are water, gas and some solid materials in mixtures extracted from underground. The method commonly used for separating the extracted mixtures of crude oil from water is the use of corrugated plates. The plates are used for gravity separation usually. In this study, the effects of three Re numbers of mixtures (3500, 4800, 6100), three values for the ratio of diameter of the hole to the width of the plate (d/w) (0.017, 0.025, 0.033) and three mounting angles of the plates to the separation unit (10, 30, 50 degrees) on the separation performance were investigated. With less experimentation and no impact on separation performance, the optimization process was carried out utilizing the design of Box-Behnken and the Response Surface Method (RSM). In addition, the same system was designed in the Computational Fluid Dynamics (CFD) program, and the optimum experiment was carried out numerically. The experimental and numerical results were compatible with one another. The ultimate separation performance was achieved as 99.25% when the mounting angle was 27 degrees, the d/w was 0.029 and the Re number was 4850.

Birleştirilmiş Plakaların Ayrıştırma Verimliliği Üzerine Etkileri

Abstract

Yeraltından çıkarılan karşımın içinde su, gaz ve bazı katı maddeler mevcuttur. Ham petrol olarak çıkartılan karışımın sudan ayrıştırılmasında en yaygın olarak kullanılan yöntem, yerçekimsel ayrışma metotlarından biri olan oluklu levhaların kullanıldığı ayrışma yöntemidir. Bu çalışma kapsamında, ele alınan petrol-su karışım numunesinin 3 farklı Re sayısı (3500, 4800, 6100), oluklu levhaların 3 farklı delik çapının levha genişliğine oranı (0.017, 0.025, 0.033) ve oluklu levhaların ayrışma sistemine 3 farklı montaj (10, 30, 50 derece) açısı parametrelerinin ayrışma verimliliğine etkisi incelenmiştir. Yapılması gereken deney sayısını azaltmak ve böylece maliyet ve deney süresinden tasarruf sağlamak amacıyla, ayırma veriminin en yüksek değerini bulma olasılığını etkilemeden, Box-Behnken tasarımı ile Yanıt Yüzey Yöntemi (RSM) kullanılıp optimizasyon işlemi gerçekleştirilmiştir. Ayrıca Hesaplamalı Akışkanlar Dinamiği (CFD) programında aynı sistem tasarlanarak optimum deney, sayısal olarak gerçekleştirilmiş ve deneysel ve sayısal sonuçların birbiriyle uyumlu olduğu görülmüştür. En yüksek ayırma verimi %99.25 olarak montaj açısı 27 derece, d/w 0.029 ve Re sayısı 4850 olduğunda elde edilmiştir.
