The impact on transportation efficiency in terms of energy consumption as well as the impact on the transport capacity of a pipeline where the equipment was sized originally for natural gas transport, are assessed. Introduction and Background The increased use of renewable energy will require...

... increasing DRA injection rates into existing assets. APPROACH Energy is consumed in order to move a barrel of oil. DRA decreases the amount of energy that is required to move that barrel of oil. A price associated with both energy consumption to transport a barrel of oil and DRA utilized to reduce...

... ABSTRACT Many gas compressor stations use multiple gas turbine driven centrifugal compressors. In many instances, the units are not identical. The challenge is to control the units such, that certain operational parameters, for example fuel consumption, pipeline capacity or maintenance...

To dynamically optimise network, operator can pull a historical day that most matches the current situation and predicted consumptions and transport, simulate different scenarios and try to improve the criteria of fuel gas while observing...

... ABSTRACT Operators of long natural gas pipeline networks with multiple gas compressor stations are looking for ways to optimize operations, reduce fuel consumption and costs, and maximize producer and consumer throughput in real time. This paper introduces a unique method to optimize...

... ABSTRACT One of the key goals of pipeline hydraulic optimization is the capability to minimize fuel consumption of gas turbine driven centrifugal compressors. This requires an accurate, and computationally efficient method to calculate the fuel consumption of a gas turbine driven centrifugal...

... Abstract As an efficient and clean burning fuel, natural gas provides one quarter of the global energy supply. It has a significant impact on national energy production, consumption, economic growth, and our daily lives. Many studies have been conducted to predict natural gas consumption based...
