This study aimed to evaluate regional soil Borkhar of the metals Lead has been made. In this field study fires visits to the regions. The limit of this study located in the East refineries, petrochemical and power plant to 20 km was selected. The 41 soil samples from depths of 0 to 10 cm in area and were randomized. Soil samples were transported to the laboratory and by air was dry and passed t...
Background and purpose: It is likely that industrial workplaces increase the chance of developing obesity and cardiovascular disease risk factors in the employees. The aim of this study was to compare obesity and some health markers between male employees of gas refinery (first exposure group) and petrochemical staff (second exposure group) compared to non-industrial male employees of general p...
Production planning is a very important step in managing the operation of a single refinery and their complexes. Despite its significance, few contributions have been found in literature and the existing ones rely on linear models. Pinto et al. (Comp. Chem. Engng. 24, 2259-2276, 2000), presented a superstructure that represents a general topology and allows the implementation of nonlinear proce...
مراتع حدود نیمی از خشکی های جهان را در بر دارند و پوشش گیاهی آن در نتیجه تأثیر متقابل محیط و موجودات زنده به وجود آمده است و به عنوان یک اکوسیستم طبیعی مدیریت می شوند. علاوه بر مراتع، راه ها در عصر حاضر نیز از اجزا مهم و زیرساخت های اصلی زندگی نوین و توسعه کشورها به شمار می روند. جاده ها ساخته دست بشر هستند و جوامع گیاهی کنار جاده تحت تأثیر ساخت و ساز قرار دارند. پوشش "رودرال" به مجموعه ای از پ...
Crude oil distillation (atmospheric distillation column with furnace) consumes about 50% of the energy required in oil refinery plant. To achieve further reduction of the energy required in oil refinery plants, it is required to investigate the crude oil distillation and to retrofit it for energy saving process. Recently, authors developed an innovative process design technology, self-heat recu...
Oil refineries provide the lifeblood for global economic health, and disruptions to their operations have major worldwide impact. We are developing a large-scale intelligent refinery control system to assist human operators in controlling refineries during abnormal situations. Based primarily on reactive and procedural approaches to intelligent behavior, the Abnormal Event Guidance and Informat...
Colour and turbidity measurement. An instrument has been designed to measure colour and turbidity using solid state light sources and sensors operating at 470 nni (blue) and 880 nni (infrared) respectively. It is intended to be a factory instrument suitable for detecting break through from filters and colour gain or loss over scctions of plant in a refinery. The measurements are exprcssed in ab...
Refinery sludge is one of the major industrial wastes that needs to be handled and treated . Therefore, this study aim to investigate the Kinetics of devolatilization and oxidation of the refinery sludge collected from a typical petroleum refinery plant located in Malaysia . Thermo Gravimetric Analyzer (TGA) was used in this study for modeling of the devolatilization and oxidation processes in ...
In this paper, the power plant cycle of Isfahan refinery with the capacity of 64 MW was discussed and irreversibility percentage and exergy efficiency were calculated for cycle component using exergy, energy and mass balance equations. Also, the results obtained from exergy analysis introduced boiler as the most important factor for exergy destruction. Increasing feed water temperature has a...
Nuisance alarms often clutter and obscure an operator’s view of critical and important information. In this paper, an intelligent alarm management system for a refinery plant is presented. Its function includes nuisance alarm suppression, intelligent advisory information to guide operator response and recovery mechanism in case of system failure. This system is implemented on Distributed Contro...
