-Perform debottleneck studies on various systems and developed recommendations that were implemented to meet new target rates. Systems include large (6000gpm+) multi water well system, waste cavern system, and chloralkali primary brine treatment system. The studies included equipment specs review, NPSHa study, hydraulic simulations for waste caverns and water well systems (including automatic drawdown adjustment for wells), and equipment push test to document current capacity. Recommendations included pipe system modifications, sizing of new pipe/control-valve/meters, new control scheme, sizing of new freshwater well pumps, water well rehabilitation schedule recommendations, plot plans, P&ID redlines, and scenario PFDs for operator training. -Optimize precipitation reactor tank performance. Effort covered plans to retrofit tank to clarifier, tank precipitant removal system, hydraulic study of proposed options, equipment sizing calcs, and contractor bidding process. -Develop and execute water/brine quality test (EDTA titration,Hach3900 spectrophotometer, conversion factor calcs).-Customize water quality labs for brine compatibility.-Pipeline pump sizing and related analysis; review of pipeline smart pig data to determine ID profile vs length, hydraulic simulation, comparison of operational data (pressure/flows/rpm) vs simulation results to confirm agreement.-Experienced simulating storage cavern hydraulics to estimate hydrocarbon import/export rates and brine injection pump capacity requirements.-Develop FEED deliverables (equipment sizing calcs, plot plans, line sizing&routes, pump foundation drawings, tank drawings, ect) with detail needed to request equipment and contractor quotes.-Design and execute benchtop labs for brine treatment to compare filterability of different sources. This covers measuring raw brine impurities to be removed, calculating required precipitating agents, collecting timed filtration volumes, and measuring impurities in filtrate.
