Iranian offshore oil and gas platforms are mostly located in the Persian Gulf. Technical and environmental challenges resulted from an off-design running condition of processes on a platform are important issues. The weakness of strategies to stop or decrease the amount of greenhouse gas emission production rate in the Persian Gulf; which is intensively increasing, is another matter of concern....
One of the most important methods of transporting natural gas in Iran and other parts of the world is the utilization of a network of pipelines. Compression station and turbo compressor units play an important role in gas supply through pipelines. One of the primary concerns in these units is the reduction of fuel consumption. By cooling of exhaust gas from the source station, the pressure drop...
یکی از راههای افزایش راندمان حرارتی واحدهای میکروتوربینی، استفاده از حرارت گازهای داغ خروجی از توربین می باشد که این گرما در مبدل حرارتی ( ریکوپراتور) به هوای خروجی از کمپرسور منتقل شده و بدین طریق میزان سوخت مصرفی سیکل کاهش یافته و در نتیجه راندمان این واحد ها افزایش می یابد. ریکوپراتورها مبدل های حرارتی گاز به گاز فشرده¬ای هستند که با نسبت سطح به حجم بالایی، میزان انتقال حرارت ما بین گاز خروج...

The Global Lung Function Initiative (GLI) Network has become the largest resource for reference values for routine lung function testing ever assembled. This article addresses how the GLI Network came about, why it is important, and its current challenges and future directions. It is an extension of an article published in Breathe in 2013 [1], and summarises recent developments and the future o...
The problem of factors influencing the sensors in a mine gas monitoring system cannot be solved by a single sensor itself. The multi-sensor information fusion technique was put forward to increase the system’s information utilance, precision, dependability and error tolerance. Based on the information source that the mine gas monitoring system has collected, the system’s structure mode was defi...
Predicting the Hydrate Stability Zones of Natural Gases Using Artificial Neural Networks — A feed-forward artificial neural network with 19 input variables (temperature, gas hydrate structure, gas composition and inhibitor concentration in aqueous phase) and 35 neurons in single hidden layer has been developed for estimating hydrate dissociation pressures of natural gases in the presence/absenc...
The most costly operation in the oil exploration is the well network drilling. One of the most effective ways to reduce the cost of drilling networks is decreasing the number of the required wells by selecting the optimum situation of the rig placement. In this paper, Balas algorithm is used as a model for optimizing the cost function in oil well network, where the vertical and directional dril...
