Chemical Process Engineer - Integrated Water Management

CHEMICAL PROCESS ENGINEER - INTEGRATED WATER MANAGEMENT

Job Type: Full-Time

The Chemical Process Engineer
- Integrated Water Management provides technical expertise in chemical process engineering, produced-water treatment, water chemistry, process design and optimization, field execution, and customer support.

The position develops safe, reliable, and cost-effective water-treatment solutions that meet customer specifications, regulatory requirements, and DHI performance standards. Applications may include produced-water recycling, frac-quality water, industrial water treatment, and beneficial reuse.

• Analyze produced, recycled, source, and groundwater to determine treatment requirements.
• Develop treatment strategies based on water chemistry, operating conditions, intended use, and finished-water specifications.
• Evaluate compatibility when blending water from different formations, operators, or facilities.
• Identify scaling, corrosion, precipitation, solids, bacterial activity, and chemical incompatibilities.
• Establish chemical programs, dosage rates, injection locations, retention times, process controls, and monitoring requirements.
• Evaluate compatibility between treated water and customer frac chemical programs.
• Develop water, chemical, contaminant, and solids mass balances.
• Oversee laboratory and field testing of water sources and treatment systems.
• Interpret analytical data and convert findings into process and field recommendations.
• Conduct bench-scale and compatibility testing before process changes or introduction of new water sources.
• Evaluate and optimize scale inhibitors, corrosion inhibitors, biocides, oxidizers, coagulants, flocculants, pH adjustment, disinfection, clarification, and solids-control chemicals.
• Evaluate chemical reactions and hazards associated with mixing water, chemicals, and process streams.
• Review Safety Data Sheets, chemical specifications, and reaction data before approving new chemicals.
• Support SOPs, JSAs, Process Hazard Analyses, startup safety reviews, Management of Change, and emergency-response procedures.
• Participate in incident investigations, root-cause analyses, and corrective actions.
• Design and optimize treatment processes involving chemical injection, clarification, solids separation, filtration, flotation, polishing, membranes, and discharge systems.
• Establish operating parameters for flow, pressure, chemical dosing, retention time, capacity, and treatment performance.
• Support system commissioning, startup, tuning, and steady-state operation.
• Troubleshoot process upsets, equipment failures, chemistry issues, flow disruptions, and water-quality deviations.
• Evaluate filtration, reverse osmosis, desalination, oxidation, disinfection, and other produced-water treatment technologies.
• Compare treatment alternatives based on performance, cost, chemical use, waste generation, reliability, and field maintainability.
• Support process design and operation of pumps, tanks, chemical systems, DAF units, filters, membranes, piping, and instrumentation.
• Evaluate materials of construction for compatibility with water chemistry, chemicals, and operating conditions.
• Ensure systems meet customer specifications, reuse requirements, permits, regulations, and DHI standards.
• Track uptime, treatment efficiency, water recovery, water quality, chemical use, cost per barrel, and system reliability.
• Improve process performance while reducing chemical consumption, waste, and operating costs.
• Lead or support 5S, DMAIC, SOP updates, and continuous-improvement projects.
• Evaluate chemical vendors and validate recommendations through laboratory and field testing.
• Serve as a technical representative during customer meetings and site visits.
• Support technical scopes, bid packages, system sizing, cost modeling, and treatment-job estimates.
• Train operators and technicians on chemistry, treatment processes, chemical safety, sampling, process controls, and equipment operation.
• Prepare and review treatment, water-quality, chemical-usage, downtime, cost, and customer reports.
• Maintain laboratory results, treatment logs, chemical records, approvals, daily reports, and billing documentation.

• Achievement of customer water-quality objectives.
• Safe execution of chemical treatment programs.
• Treatment-system reliability and uptime.
• Process efficiency, water recovery, and consistent performance.
• Effective control of chemical use and treatment cost.
• Accurate testing,…
