Plant Chemistry Technician

The Rayburn Energy Station 1, located in Sherman, TX, is a 750 MW natural gas-fired combined-cycle power plant. The facility features two Siemens SGT6-5000F combustion turbine generators, each paired with a dedicated Heat Recovery Steam Generator (HRSG) to produce steam and improve overall plant efficiency.

The Plant Chemistry Technician supports the safe, reliable, and efficient operation of Rayburn Energy Station 1 (RES
1) by managing plant chemistry, water-treatment, wastewater, and environmental programs. This position oversees water/steam-cycle chemistry, cooling-water treatment, reverse osmosis and demineralized-water systems, Zero Liquid Discharge (ZLD) chemistry, chemical treatment, laboratory analysis, and online monitoring. The Plant Chemistry Technician works closely with Operations, Maintenance, Engineering, Environmental, vendors, and OEM representatives to identify chemistry-related risks, optimize system performance, and maintain regulatory compliance.

• Develop and manage plant chemistry programs in accordance with OEM guidance, industry practices, environmental permits, and plant procedures.
• Provide technical oversight of condensate, feedwater, HRSG, steam, cooling-water, and chemical-treatment programs to control corrosion, scaling, deposition, and equipment damage.
• Monitor and optimize reverse osmosis, demineralized-water, cooling-water, and ZLD systems, including water quality, chemical usage, membrane performance, and treatment effectiveness.
• Establish and maintain chemistry control limits, action levels, sampling frequencies, laboratory methods, alarm limits, and response procedures.
• Collect and analyze water, steam, wastewater, chemical, and other process samples using approved laboratory methods.
• Operate, calibrate, and troubleshoot laboratory and online analytical equipment, including pH, conductivity, dissolved oxygen, silica, sodium, and related instrumentation.
• Analyze chemistry and process data to identify adverse trends, treatment deficiencies, equipment risks, and opportunities to improve reliability, water usage, chemical consumption, and operating cost.
• Investigate chemistry-related issues involving corrosion, scaling, fouling, contamination, water-treatment upsets, equipment damage, or abnormal operating conditions and support corrective actions and root‑cause analysis.
• Support startups, shutdowns, outages, and equipment layup through chemistry monitoring, flushing, preservation, sampling, inspection, and treatment planning.
• Coordinate chemical management including procurement, inventory, storage, labeling, compatibility, transfer practices, spill response, and SDS requirements.
• Support environmental compliance through sampling, monitoring, data review, recordkeeping, and technical assistance related to water, wastewater, and chemical programs.
• Maintain accurate records and reports covering chemistry results, equipment calibrations, chemical usage, inventories, procedures, vendor activities, and regulatory requirements.
• Provide technical guidance and training to Operations and other plant personnel on sampling, testing, chemical handling, water treatment, and response to abnormal chemistry conditions.
• Collaborate with Operations, Maintenance, Engineering, Environmental, Safety, contractors, chemical suppliers, laboratories, vendors, and OEM representatives to support safe and reliable plant operation.
• Performs other duties and special projects as assigned by the Operations Manager.

Safety is a core value at NAES, and as a condition of employment, all employees are expected to remain mentally alert and work safely at all times. Employees must also adhere to all safety warnings and posted signs while on company property. Additionally, they are required to follow all NAES safety rules and procedures. Adherence to these safety responsibilities is one of the key factors in the evaluation of each employee’s performance.

The Plant Chemistry Technician reports to the Operations Manager and works closely with Operations, Maintenance, Engineering, Environmental, Safety, and administrative personnel and routinely coordinates with treatment-chemical suppliers, laboratories, contractors, OEM representatives, and regulatory or Owner representatives as applicable.
