Performance of a gas turbine mainly depends on the inlet air temperature. The power output of a gas turbine depends on the flow of mass through it. This is precisely the reason why on hot days, when air is less dense, power output falls. The objective here is to assess the advanced systems applied in reducing the gas turbine intake air temperature and examine the merits from integration of the ...

Abstract We study combinatorial structures in large-scale mixed-integer (nonlinear) programming problems arising gas network optimization. propose a preprocessing strategy exploiting the observation that large part of complexity arises certain subnetworks. Our approach analyzes these subnetworks and structure flows within order to provide alternative models with stronger can be exploited by off...

arguably, the natural gas transmission pipeline infrastructure in iran represents one of the largest andmost complex mechanical systems in the world. the optimization of large gas trunk lines known asigat results in reduced fuel consumption or higher capability and improves pipeline operation. in thecurrent study, a single-objective optimization was conducted for khormoj compressor station on t...

In this paper we consider the usage of multiple base stations for IP streaming applications towards wireless terminals. The usage of multiple channels, coming from different base stations, increase the capacity and robustness at the price of an additional IP overhead. Therefore, we advocate to use a novel IP header compression scheme for efficient usage of spectrum resources. We propose the coo...

Natural gas processing plants and their associated compressor booster stations emit an estimated 36 billion cubic feet (Bcf) of methane annually. More than 24 Bcf of total methane losses from gas plants are fugitive emissions from leaking compressors and other equipment components such as valves, connectors, seals, and openended lines. Implementing a directed inspection and maintenance (DI&M) p...

This special report looks at the use of natural gas pipeline compressor stations on the interstate natural gas pipeline network that serves the lower 48 States. It examines the compression facilities added over the past 10 years and how the expansions have supported pipeline capacity growth intended to meet the increasing demand for natural gas. Questions or comments on the contents of this art...

The aim of this paper is to present a methodology for optimizing the operation of compressors in parallel in process industries. Compressors in parallel can be found in many applications for example in compressor stations conveying gas through long pipelines and in chemical plants in which compressors supply raw or processed materials to downstream processes. The current work presents an optimi...
