Waste Hydrogen Pipelines Monitoring in Modern Power Plant

Abstract : Many production processes in chemical industry generates hydrogen as a by-product. Part of this is reused in the other production process, however significant amount that is wasted can be used for energy production in stationary application. The goal of the project was development of the technology for safe exploitation of by-product hydrogen in chosen chemical plant. During the pilot project a small power plant with electrical capacity of 1 MW was designed and constructed. Two energetic technologies were applied. First use hydrogen and hydrocarbons as a fuel for combustion generators (leading technology), and the second one use purified hydrogen for fuel cells (complementary technology). A big attention was put on safety aspects and structural health monitoring of the most critical elements. An innovative technology based on distributed optical fiber based sensors for hydrogen pipeline integrity and leakage detection was applied. A temperature distribution along each of four supply gas pipelines (one with pure hydrogen to the fuel cell and three others with waste hydrogen to power generators) is permanently monitored.
