Pipeline transport detection. Benzene typically makes up 0.1 – 1.0% of oil and will have varying degrees of volatility and dissolution based on environmental factors. Even with pipeline leak volumes within SCADA detection limits, sometimes pipeline leaks are misinterpreted by pipeline operators to be pump malfunctions, or other problems. The Enbridge Line 6B crude oil pipeline failure in Marshall, Michigan on July 25, 2010 was thought by operators in Edmonton to be from column separation of the dilbit in that pipeline. The leak in wetlands along the Kalamazoo River was only confirmed 17 hours after it happened by a local gas company
CLH Pipeline System CLH Pipeline System The CLH Pipeline System (CLH-PS), formerly the Government Pipelines and Storage System (GPSS), is a United Kingdom pipeline system run by Compañía Logística de Hidrocarburos (CLH). The network at one time consisted of over of pipeline and 46 other facilities. However, several of these facilities were closed before the GPSS was sold in 2015 and a number of the pipelines were mothballed and later 'abandoned'. Earlier the total number of facilities on the GPSS was much larger than 46. For example, in 1989 there were 40 Petroleum Storage Depots in operation plus large numbers of other facilities
