“…Batch CO 2 precipitation microcosms were prepared in sterile 35 mL serum bottles in a laminar flow hood. Each microcosm included 20 mL of a synthetic brine (SB) with approximately 5 g L -1 total dissolved solids (TDS), mimicking the ionic ratios present in the proposed Powder River Basin CO 2 injection site (20). Specific inorganic constituents of the SB are shown in the Supporting Information (SI) Table 1.…”

“…Here the effect of bacterially induced ureolysis on CaCO 3 precipitation was investigated for a range of fixed initial CO 2 headspace pressures and urea concentrations in synthetic brine mimicking the Powder River Basin in Wyoming, a prospective CO 2 injection site in the western U.S. (20). Lower than reservoir pressure conditions are considered in this study in order determine the general relationship between ureolysis, mineral formation, and carbonate sources, as well as to ensure the applicability of modeling results, for which accurate thermodynamic data exists.…”

The potential of microorganisms for enhancing carbon capture and storage (CCS) via mineral-trapping (where dissolved CO(2) is precipitated in carbonate minerals) and solubility trapping (as dissolved carbonate species in solution) was investigated. The bacterial hydrolysis of urea (ureolysis) was investigated in microcosms including synthetic brine (SB) mimicking a prospective deep subsurface CCS site with variable headspace pressures [p(CO(2))] of (13)C-CO(2). Dissolved Ca(2+) in the SB was completely precipitated as calcite during microbially induced hydrolysis of 5-20 g L(-1) urea. The incorporation of carbonate ions from (13)C-CO(2) ((13)C-CO(3)(2-)) into calcite increased with increasing p((13)CO(2)) and increasing urea concentrations: from 8.3% of total carbon in CaCO(3) at 1 g L(-1) to 31% at 5 g L(-1), and 37% at 20 g L(-1). This demonstrated that ureolysis was effective at precipitating initially gaseous [CO(2)(g)] originating from the headspace over the brine. Modeling the change in brine chemistry and carbonate precipitation after equilibration with the initial p(CO(2)) demonstrated that no net precipitation of CO(2)(g) via mineral-trapping occurred, since urea hydrolysis results in the production of dissolved inorganic carbon. However, the pH increase induced by bacterial ureolysis generated a net flux of CO(2)(g) into the brine. This reduced the headspace concentration of CO(2) by up to 32 mM per 100 mM urea hydrolyzed because the capacity of the brine for carbonate ions was increased, thus enhancing the solubility-trapping capacity of the brine. Together with the previously demonstrated permeability reduction of rock cores at high pressure by microbial biofilms and resilience of biofilms to supercritical CO(2), this suggests that engineered biomineralizing biofilms may enhance CCS via solubility-trapping, mineral formation, and CO(2)(g) leakage reduction.

“…Two end-member brines with dissolved solid concentrations of 0.99 g/L and 9.9 g/L, respectively, were prepared using Type-1 ultrapure de-ionized water (Millipore Milli-Q) and laboratory-grade chemicals. The brine recipe was designed to approximate natural brines reported from the Powder River basin, Wyoming (Busby et al, 1995) with 0.033 M/L NaCl and CaCl 2 , 0.035 M/L MgSO 4 and 0.001 M/L MgCO 3 . Brines were pH balanced to 6.5 ± 0.2 units using HCl and NaOH.…”

Sandstone and carbonate core samples were challenged with a two phase supercritical CO 2 and brine mixture to investigate the effects of chemical processes on the physical properties of these rocks during injection of CO 2. Experiments were monitored in real-time for pressure, temperature, and volumetric rate discharge. Pore geometry and connectivity were characterized before and after each experimental challenge using Magnetic Resonance (MR) imaging and two dimensional MR relaxation correlations. Quartz arenite sandstone cores were largely unaffected by the challenge with no measurable change in effective permeability at moderate and high temperatures (~50°C, ~95°C) or brine concentrations (~1g/L, ~10g/L). In contrast, a carbonate core sample showed evidence of significant dissolution leading to a six-fold increase in effective permeability. MR images and relaxation measurements revealed a marked increase in the volume and connectivity of pre-existing pore networks in the carbonate core. We infer that the increase in permeability in the carbonate core was enhanced by focused dissolution in existing pore and fracture networks that enhanced fast-flow paths through the core.

The volume of brackish groundwater that is available for use is quite large and geographically extensive.…”

Economics and Energy Consumption of Brackish Water Reverse Osmosis Desalination: Innovations and Impacts of Feedwater Quality

et al. 2021

Brackish water desalination, using the reverse osmosis (BWRO) process, has become common in global regions, where vast reserves of brackish groundwater are found (e.g., the United States, North Africa). A literature survey and detailed analyses of several BWRO facilities in Florida have revealed some interesting and valuable information on the costs and energy use. Depending on the capacity, water quality, and additional scope items, the capital cost (CAPEX) ranges from USD 500 to USD 2947/m3 of the capacity (USD 690–USD 4067/m3 corrected for inflation to 2020). The highest number was associated with the City of Cape Coral North Plant, Florida, which had an expanded project scope. The general range of the operating cost (OPEX) is USD 0.39 to USD 0.66/m3 (cannot be corrected for inflation), for a range of capacities from 10,000 to 70,000 m3/d. The feed-water quality, in the range of 2000 to 6000 mg/L of the total dissolved solids, does not significantly impact the OPEX. There is a significant scaling trend, with OPEX cost reducing as plant capacity increases, but there is considerable scatter based on the pre- and post-treatment complexity. Many BWRO facilities operate with long-term increases in the salinity of the feedwater (groundwater), caused by pumping-induced vertical and horizontal migration of the higher salinity water. Any cost and energy increase that is caused by the higher feed water salinity, can be significantly mitigated by using energy recovery, which is not commonly used in BWRO operations. OPEX in BWRO systems is likely to remain relatively constant, based on the limitation on the plant capacity, caused by the brackish water availability at a given site. Seawater reverse osmosis facilities, with a very large capacity, have a lower OPEX compared to the upper range of BWRO, because of capacity scaling, special electrical energy deals, and process design certainty.
