Penggunaan Metode Risk Based Inspection API 581 Tahun 2000 sebagai Dasar Analisis Risiko Sistem Producer Gas PLTSa Surakarta
Abstract – The Surakarta Waste Power Plant (PLTSa) is planned to start operating in 2023. PLTSa uses gasification process technology to process waste. In the waste gasification process, the gas produced is syngas or producer gas, which is a mixed gas consisting of hydrogen compounds (H2), carbon monoxide (CO), and several compounds with small concentrations such as carbon dioxide (CO2) and methane (CH4). The syngas production process begins with the waste gasification process in the Gasifier equipment where the waste is heated at high temperatures until it reaches the conditions for gasification. Furthermore, syngas will go through a gas conditioning process. In this process, the properties of syngas changes in each equipment and pipe line it passes through. Each property of syngas can affect the metal material which is the basic material of equipment and pipes so that it can result in system failure. With the difference in fluid properties and pipe and equipment materials in the system, there will be differences in damage mechanisms, which means that there are also differences in inspection treatment in each part of the plant. Thus, determining the right inspection program can be done by conducting a risk analysis based on the API 581 2000 standard.
