... Abstract Dynamic programming (DP) has a fifty-year history of optimizing pipeline operations. While this was originally limited to deciding pump lineups and pump and valve setpoints in single steady states, the increasing power of modern computers makes it possible to use this technique...

... delivery schedules. It describes the potential estimated savings that can be achieved by optimal configuration of the pumps/compressors, DRA (Drag Reducing Agent) injections etc. air emission pipeline psig 2308 united states government co2 emission midstream oil & gas climate change...

.... The complex operations of large water tank-and-pipeline networks present a good opportunity for numerical optimization. While during normal usage these networks can be expected to more or less follow a daily cycle, an optimizer is helpful when planning maintenance, when dealing with equipment failures...

... and the role of hydraulic analysis. The main elements of network modelling will be briefly reviewed. Aspects of steady state vs. transient modelling as well as simulation vs. optimization will also be discussed. A variety of solution methods for different network structures will be pointed out. A practical...

... of a pipeline optimization tool. In 2002 Planning developed an in-house tool that utilized an off-the-shelf optimization program. The primary drawback to this approach was the runtime required to generate a solution. TGP conducted a pilot study with Adaptive Decisions' "Adaptive Enterprise Optimization...

... the gas over long distances. The operating costs of transmission pipelines can be significant because of compressor station fuel costs, emission minimization, etc. The analysis of these pipelines is very complex. This paper details techniques that can be used to determine optimal operating regions...

... ABSTRACT Following the history of steady state optimization applied to OMV's distribution and transmission systems, the development of an optimization method, based on Sequential Linear Programming will be described. An iterative cooperation between a detailed simulation model and a simplified...

... ABSTRACT Engineering design and planning studies of pipeline networks are often involved with the task of optimizing the performance of the overall system, in some sense. In recent years, optimization packages based on pipeline network simulators have become available for the engineer to use...

... within the gathering system. A flow optimizer, which adjusts the flow rates from the component wells and compression at the Central Processing Platforms to maximize the field's current economics. A project scheduler, which adds facilities to the network when required to increase capacity when the current...

... ABSTRACT Due to a number of technological and economic changes in the pipeline industry, interest in optimization software is growing rapidly. Recent governmental regulations and widespread use and acceptance of modeling software in the industry have given rise to applications of optimization...

... will became the leader. Several companies have turned to transient simulation models and/or steady state optimization programs to assist their efforts. These tools, used separately and together, allow companies to realize significant fuel cost reductions. However, the separation of the transient analysis from...
