Screw Element Separator

• Process and Functional Design including Process and Instrumentation Diagrams. Included both functional write ups of systems and P&ID drawings.

• Design, Detailing, Project Estimating, and BOMs for Integrated Mechanical Systems in compliance with UL, CE, and ASME standards. This includes calculations for stress/strain, shear, torsion, fluid flow rates, fluid pressures, failure analysis, materials selection, equipment sizing, and cost estimating.

• Project Management for Installation of Equipment in the Field

• Supervise/Mentor new Engineers and Interns

• Technical writing for equipment users manuals.

• Part of a team that streamlined and compartmentalized the equipment design process using Lean Six Sigma tools for rapid engineering, purchasing, and assembly. Role included 3D modeling of machinery parts, developing a parts database, cross referencing parts, and standardizing parts across all equipment lines. In some cases this allowed the engineers to make design changes to a single part that was used in multiple locations. Included performing design/calculations to ensure such parts would endure the fitment, stress, heat, etc. of multiple applications.

• Design of a precision machined, co-rotating splitter gearbox. This included calculating rotational velocities, bearing life, gear tooth stress/strain, coupling stress/strain, tension, torsion, and compression forces from the process and attached motors, etc.

• Part of the engineering team for the design and installation of a duplex air stripper system for the purpose of removing trace amounts of trichloroethylene (TCE) solvent from process oil. Included mass air flow and volumetric oil flow controls for variable speed operation. Engineering included:

• Stripper air flow and pressure calculations for fan sizing.

• Steam system piping pressure, temperature, flow calculations for heat exchanger, valve, and flow meter sizing. *Oil piping calculations for flow and pressure to size pumps, pipe, and valves.

• Mass airflow calculations for sizing the solvent/air/oil filtration system.

• Multi-Engineer project for research, design, and installation of a continuous web curing oven for removing trace amounts of TCE and water from a micro porous plastic sheet (CE, ASME, and UL compliance) Engineering included:

• Calculations necessary to design the stretching portion of the curing line (oven).

• Steam system piping pressure, temperature, flow calculations for heat exchanger, valve, and flow meter sizing.

• Oil piping calculations for flow and pressure to size pumps, pipe, meters, and valves.

• Airflow calculations for sizing extraction ducting.

• Torque, stress/strain, bending, fatigue, and compression calculations for designing custom motor couplings, sizing VFD/Motors, closures and fasteners, screw jacks, equipment frames, etc.

• Multi-Engineer project for the design of a continuous multistage flash distillation system for separation of high concentrations of TCE in process oil. Engineering included:

• Distillation sizing and calculations for the pumping and vacuum system.

• Calculations included airflow velocities and pressures, pump volumes and design head, and vacuum line sizing.

• Required pumps for low NPSH and liquid thermosiphon shaft seals/cooling.

• Design of oil precipitators and filtration for a smoke collection system. Work included:

• Interfacing with the plant work crews and developing solutions to air quality control.

• Collection of data on solvent and oil mist concentrations throughout the plant, calculated capture velocities and drop-out velocities for knockdown and filtration equipment, sized collection nozzles and ducting, and designed custom capture equipment for each of the different production lines.

• Solvent source concentration and encapsulation study

• Researched and developed improvements for continuous web slitting systems. Engineering included:

• Tabulating cost data on the existing equipment, measuring failure rates, measuring cutting stresses, calculating rotation speeds, and calculating stress/strain of the existing and proposed support structure.

• Researched and developed improvements for a quality assurance laser measurement device. Researching solutions to the measurement error of the equipment. This included testing different lasers and different programming algorithms in concert with the laboratory staff.

• Installation and Commissioning supervision for equipment installations at customer sites. Included calculations necessary to interface with the customer infrastructure: ie. vacuum, water, oil, air, line sizing to match newly installed equipment.

• Design for a multi-functional extrusion machine screw element separator. Calculations included stress/strain for the exoskeleton, hydraulic line and pump sizing, and shear force requirements on the screw/foot interface and screw/shaft interface.
