Catalytic sulfur and contaminant removal for low-sulfur diesel production.
Feed preparation, hydrogenation, high-pressure separation, recycle gas and stripping. The operating sequence, recycle paths, start-up/shutdown cases and normal/turndown behavior are defined before equipment finalization.
Reactor, charge heater, exchangers, separators, compressor, stripper and amine interface. 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.
Kinetic/licensor basis, hydrogen balance, PFD/P&ID, safeguards and guaranteed-product test plan. 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.
ULSD production, gasoil upgrading and refinery revamps. Capacity, product quality, consumption and emissions commitments are confirmed only after the representative feed and project Design Basis are approved.
ASTM/EN product methods, API, ASME, NACE where applicable. 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.
