Hydrogen production and purification sized to refinery consumers and purity requirements.
Feed desulfurization, steam reforming, shift conversion, cooling and PSA purification. The operating sequence, recycle paths, start-up/shutdown cases and normal/turndown behavior are defined before equipment finalization.
Desulfurizer, reformer, shift reactors, waste-heat boiler, PSA and compressors. Materials, design margins, maintainability, isolation, access, lifting and spare philosophy are coordinated with the approved operating cases.
Feed assay/composition, design capacity, operating pressure and temperature, product specifications, turndown, utilities, battery limits and site ambient conditions.
Hydrogen balance, reformer design basis, steam integration, safeguards and purity test procedure. The package also includes line/equipment lists, relief and utility summaries, layouts or 3D interfaces, vendor-document requirements, inspection plans and commissioning inputs as applicable.
DCS regulatory control, critical interlocks, relief and depressuring, gas/fire detection, hazardous-area classification, HAZOP actions and applicable SIS/ESD functions.
Hydrotreaters, hydrocracking and chemical-process hydrogen demand. Capacity, product quality, consumption and emissions commitments are confirmed only after the representative feed and project Design Basis are approved.
API 560, ASME, NFPA, IEC and reformer/PSA vendor standards. The contractual code basis is selected by destination and client specification. ASME/API/TEMA, EN/DIN and GOST/EAC requirements are not mixed without an approved code-equivalency and authority review.
