Why the Work Mattered

Purpose and Operating Need

Increase WDV production by 5.8M 100-grain gallons per year and increase WDV production by 446,500 100-grain gallons per year from conversion of existing units.

Engineering Approach

Engineering Approach

Engineering scope: acetator tanks and aerators, scrubber columns, filtration equipment, cooling tower, cooling-water separator, standby generator and automatic transfer switching, PLC PLC and operator interface Visual SCADA.

Outcome & Engineering Context

Outcome and Context

Planned 5.8M additional 100-grain gallons/year, plus 446,500 100-grain gallons/year from conversion of existing units. These are source planning targets, with no final operating-capacity acceptance asserted.

ACTIVITIES IN CONTEXT

Additional Technical Detail

Roles & contributions
  • Project Ownership

    Full lifecycle project ownership

    Owned the full project lifecycle: capital planning and prioritization, need definition, feasibility and scope development, engineering and AFE justification, procurement and vendor coordination, construction sequencing and field oversight, commissioning, turnover, and post-startup support. Connected operating requirements with technical scope, funding decisions, execution readiness, and the needs of operations and maintenance.

  • Project Stakeholder

    Project coordination

    Project coordination

    Project stakeholder was assigned pre-startup equipment and piping cleaning in the AFE.

  • Assigned pre-startup responsibility

    The acetator AFE assigns cleaning of all equipment and piping before startup to Project stakeholder. This is the recorded responsibility assignment, not a separate claim of personal execution by James.

Project ownership and delivery context

Owned the full project lifecycle: capital planning and prioritization, need definition, feasibility and scope development, engineering and AFE justification, procurement and vendor coordination, construction sequencing and field oversight, commissioning, turnover, and post-startup support. Connected operating requirements with technical scope, funding decisions, execution readiness, and the needs of operations and maintenance.

Developed the integrated scope for acetator tanks, air and cooling services, scrubber connections, filtration and standby power. PLC and HMI requirements connected equipment behavior with operator visibility and the verification needed for startup.
