... Abstract Product mixing occurs often in batched liquid-phase pipelines. If not successfully mitigated, this can result in a product being assigned as a less valuable one at the terminal end, leading to a significant financial impact. There is also risk of contamination of one product...

... Abstract Real-time leak detection on short liquid pipelines is challenging due to system fluctuations of a few seconds or less. This presentation reviews a leak detection system for short liquid lines involving rapid pressure and flow sensors at pipeline ends, coupled with a fast simulator...

... flow is decreasing in size, the downstream flow rate will be less than upstream flow rate, which will appear as a leak to an online model. Via an uncertainty analysis, it is shown that it is not possible for an online model to predict slack flow accurately, particularly if the pipeline is batched...

... Abstract There are many pipelines around the world that move petroleum products from origination to ultimate delivery. The process starts on the production side by transporting the product from the wells to the refineries and then transporting the refined products to the end user. A large...

... on the opportunities that hydrogen presents. Hydrogen offers an opportunity that can benefit from the significant infrastructure that is already in place as part of the fossil fuel industry, but there are risks. Hydrogen embrittlement poses a significant risk to high-pressure steel transmission pipelines, putting...

... Abstract Capturing and sequestering greenhouse gases opens new opportunities for pipeline infrastructures. Along corridors of industrial areas, plant-wide carbon capture systems will feed the captured anthropogenic CO 2 into trunk lines that will transport the CO 2 to locations where it can...

..., transportation, and residential end use. However, natural gas still accounts for a large proportion of primary energy consumption for heating and electricity in many parts of the world. Interest has grown recently in blending hydrogen produced using renewable energy into existing natural gas pipelines...

... Abstract When a simulator is configured for an existing pipeline, it always needs adjustment to get it reproducing the line’s exact behavior. The engineer must determine unknown quantities such as pipe roughness and ground thermal parameters, but also identify which things they think they know...

... Abstract Enbridge’s (“The Company”) Transportation South pipeline (“The Pipeline”) is over 550 miles (900 km) long and has twelve compressor stations with a daily throughput of approximately two BCF primarily feeding the Vancouver, British Columbia and US Pacific Northwest. While operating...

... Abstract During the operation of multiphase and single-phase pipelines, gas/liquid phase transitions can significantly influence the efficiency of the pipeline. Gas/liquid phase changes occur when pipes are exposed to particularly high or low temperatures. The energy absorbed or released...

... Abstract In this paper, the problem of simultaneously optimizing both batch flow rates and drag reducing agent injection rates using gradient-free optimization heuristics is explored. Multiple pipeline test cases will be considered in order to assess the impact of variable speed and fixed...

... Abstract This study is focused on how to do the most efficient customer curtailment in terms of pipeline network, financial and social welfare. The author tries to combine the regulations from the Indonesian government regarding the prioritization of gas distribution with the negative balance...

... Abstract Gas hydrates are a major flow assurance problem in the oil & gas industry. If not treated well, they pose a major threat to pipeline failure. In this work, a simple statistical correlation is developed for the prediction of gas hydrate formation temperature. For this, initially...

... Abstract Accumulation of sand within pipelines can pose significant problems in the oil and gas industry. Sand particles tend to settle out of suspension leading to the formation of stationary or moving beds along the bottom of pipelines. Such beds provide an environment that result in flow...

... station field data pipeline psig 2205 california Abstract Reduced order models, commonly referred to as ROMs, have been used in many areas of engineering due to their reduced complexity and corresponding speed of computation and solution. In transient pipeline simulation, transfer function...
