Investigation of solid particle erosion‐related failures in once‐through steam generators (OTSGs) in oil sands in‐situ production: The limitations of the API RP 14E guideline in OTSG design or operational decision‐making

Canadian Journal of Chemical Engineering, 2023
Abstract The required steam for steam‐assisted gravity drainage (SAGD) oil sands operations is generated using a once‐through steam generator (OTSG) that is fed with relatively poor quality process water. Industries have reported possible solid particle erosion‐related failure in the OTSG boiler tubes because of the transport of precipitated dense ...
