Recovery of residual sulfur species from SRU tail gas to meet overall sulfur-recovery and emissions targets.
Tail-gas reduction, cooling, quench, amine absorption/regeneration and recycle to SRU. The operating sequence, recycle paths, start-up/shutdown cases and normal/turndown behavior are defined before equipment finalization.
Reduction reactor, waste-heat/cooling equipment, quench tower, absorber, regenerator and incinerator 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.
Sulfur-recovery calculation, solvent balance, emissions case, PFD/P&ID, datasheets and performance test. 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.
High-recovery refinery and gas-plant sulfur complexes. Capacity, product quality, consumption and emissions commitments are confirmed only after the representative feed and project Design Basis are approved.
Licensor standards, ASME, API, NACE and environmental emission limits. 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.
