Corrosion Of Nickle Based Alloy In Batch-Mode Biomass Supercritical Water Gasification(SCWG) System

Supercritical water gasification (SCWG) is a promising thermochemical conversion technology in which supercritical water is used as the medium to convert different types of wet biomass (such as wastewater sludge, food waste or microalgae) and even crude bio-oils into hydrogenrich syngas without the need of costive pre-drying process.1 During typical SCWG conversion at temperature and pressure above the critical point of water (i.e., 374℃ and 22.1 MPa), alkali metal/metal oxide catalysts, carbon-based catalysts and Ni- or Fe-based catalysts are introduced to significantly improve the conversion efficiency on H2 production.2

Supercritical water gasification (SCWG) is a thermochemical conversion technology developed to transform various feedstocks, such as raw forest biomass materials, crude bio-oils and biowastes, into syngas (a combination of CO and H2) for clean energy production. Despite the intensive research efforts that have been applied on the development of SCWG technology, the optimal SCWG operating parameters (temperature, pressure, and biomass/water ratio, etc.) are not well defined because of the complexity of feedstock types and conversion reactor configurations (batch or continuous mode). Moreover, little information is available to determine which alloys are suitable for the reactor construction in a long-term safe and cost-effective manner.

Carbon dioxide capture, utilization, and storage (CCUS) is part of decarbonization solutions to reduce green-house gas emissions, as exemplified by the growing number of capital expenditure projects worldwide.1-2 In CCUS, the carbon dioxide (CO2) is consecutively (1) captured at origin, such as power plants and natural gas production sites, (2) separated from other gases and impurities, (3) compressed, (4) transported through pipelines, and finally (5) injected into a storage site such as deleted hydrocarbon wells, saline aquafers, coal beds, underground caverns, or seawater.1,3 Since the 1970s, specifically the first commercial carbon dioxide flooding in the United States (known as SACROC), carbon dioxide sequestration has been largely discussed in the context of enhanced oil recovery (EOR), not in the newer context of Sustainability. Nonetheless, substantial experience has been drawn from EOR, including for the selection of the right and economical materials.4 As reflected by the literature, past materials test programs have rarely given any attention to downhole jewelry alloys compared to tubulars or surface-infrastructure alloys, and consequently the track records for such bar-stock alloys are either inexistent or not readily available. 5-7 This lack of apparent return-on-experience represents a knowledge gap against the prospect of a safe greenhouse gas control method; needless to say, it also justifies the requirements for reliable well integrity monitoring solutions in carbon dioxide sequestration wells.8-9
