در این مقاله قسمت سنتز واحد اوره (بخش فشار بالا) با استفاده از ترکیب نرم افزارهای برنامه نویسی و فرایندی شبیه سازی شده است. معادله دوگانه ویلسون-گاز ایده آل با تصحیح اعمال شده بر ضریب های دوتایی به عنوان معادله حالت استفاده شده است که نتیجه های خوبی را برای کل فرایند، به جز کمپرسور به همراه دارد. در شبیه سازی کمپرسور از معادله حالت pr (peng-robinson) استفاده شده است. واحد های موجود در فرایند سن...
A fundamental understanding and simulation of fuel atomization, phase transition, mixing are among the topics researchers have struggled with for decades. One reasons this is that accurate, robust, efficient jets remains a challenge. In paper, tabulated multi-component real-fluid model (RFM) proposed to overcome most limitations make simulations affordable. Essentially, fully compressible two-p...
This paper introduces the controlled natural language PENG Light together with a language processor that is based on a bidirectional grammar. The language processor has the following interesting properties: (a) it translates declarative sentences written in PENG Light into a first-order logic notation (TPTP); (b) it generates declarative sentences in PENG Light taking syntactically annotated TP...
The phase behavior of the carbon dioxide + cycloheptane binary system for which no literature data are available has been examined at temperatures ranging from 292.6 to 372.8 K. Saturation pressures, 23.9 154.8 bar, were acquired by a synthetic and visual method. In concrete terms, an adjustable-volume high-pressure cell was utilized measure bubble dew point pressures detection transitions cons...
Abstract In this work, solubility of hydrogen in some alkenes was investigated at different temperatures and pressures. Solubility values were calculated using the Peng–Robinson equation state. Binary interaction parameters fitting state on experimental data, Group contribution method Moysan correlations total average absolute deviation for these methods 3.90, 17.60 13.62, respectively. Because...
This study proposes a simple correlation for approximating hydrogen solubility in biomaterials as function of pressure and temperature. The pre-exponential term the proposed model linearly relates to pressure, whereas exponential is merely differential evolution (DE) optimization algorithm helps adjust three unknown coefficients correlation. estimates 134 literature data points with an excellen...

Carbon dioxide (CO2) flooding is one of the most important and used enhanced oil recovery (EOR) method because it does not only increase efficiency but also as an underground CO2 storage. It considered a very complex involves knowing fluid phase behavior with different concentrations. should be noted that swelling (volume increase) dissolution carbon has significant effect on recovery. When thi...
Dew Point Control Unit (DPCU) merupakan salah satu unit utama yang penting dalam proses pemurnian gas alam. Terbentuknya metana hidrat di DPCU menjadi masalah dihadapi ketika suhu operasi diturunkan serendah mungkin pada tekanan tinggi. Untuk mencegah terjadinya pembentukan tersebut, diperlukan adanya injeksi glycol. Jenis glycol digunakan oleh Gajah Baru Central Process Platform (GBCPP) milik ...
