Full service conceptual and detailed design engineering of a new electrolysis hydrogen generation and delivery system. The combined single-phase effort began with laser scanning, conceptual PFDs, code review, P&ID generation and a HAZOP study prior to the multi-discipline detailed design and 3D modeling. The design considered electrical area classification requirements, instrumentation, and safety interlocks for generation and delivery of lighter than air combustible gas. The project included design of a new RO generation and supply system to feed the electrolysis skids and new electrical infrastructure to power all new equipment. The generation system included new foundations and steel shelter to house three electrolysis skids. The hydrogen generated is injected into the existing kiln burner fuel line via new stainless tubing to supplement the burning of petcoke, coal, or natural gas, while the oxygen generated is injected into the kiln burner combustion air duct via new stainless tubing to improve burner efficiency.
