Job Description
Reactor scale-up. Take our current single-zone pilot reactor to a multi-zone commercial system. Own residence time, gas-solid contacting, freeboard, refractory and alloy selection, and heat integration. Specify and procure the long-lead reactor itself.
Separations train. Design and commission the downstream train that splits a mixed product vapor into discrete gallium, germanium, and silicon streams. Own the thermal profile, vessel internals, materials of construction, sequencing logic, and the close-cut separations that determine final product purity.
Gas management. Own the hot corrosive gas stream end to end: reactor offtake, transport lines between unit operations, pressure balance, vent and scrub systems, and the recycle loop that closes the reagent balance at commercial scale.
Mass and energy balances, P&IDs, and equipment specs across the full refinery. Support AACE Class 3 cost estimation as we move into the commercial design phase....
