Hydrodynamic/kinetic reactions in liquid-dominated geothermal systems. Final report

PDF Version Also Available for Download.

Description

A mobile geothermal well-site test unit at the Mercer 2 well in South Brawley, California (Imperial Valley), was constructed and tested. The equipment controlled, monitored, and recorded all process conditions of single- and dual-flash power cycles. Single- and two-phase flashed brine effluents were flowed through piping component test sections to provide hydrodynamic/kinetic data for scale formation. The unit operated at flowrates in excess of 200 gpm and is designed to accommodate flowrates up to 300 gpm. Primary scale formations encountered were those of PbS, Fe/sub 2/ (OH)/sub 3/Cl (iron hydroxychloride), iron chlorides, and non-crystalline forms of SiO/sub 2/. The formation ... continued below

Primary scale formations encountered were those of PbS, Fe/sub 2/ (OH)/sub 3/Cl (iron hydroxychloride), iron chlorides, and non-crystalline forms of SiO/sub 2/. The formation of iron hydroxychloride was due to the unusually high concentration of iron in the wellhead brine (5000 mg/l).
