PROCESS & OPERATING PHILOSOPHY
Feed degassing, stripping, overhead condensation/separation and bottoms cooling. The operating sequence, recycle paths, start-up/shutdown cases and normal/turndown behavior are defined before equipment finalization.
REFINERY UNITS
Sour Water Stripping (SWS)
Removal of H₂S and ammonia from refinery sour-water streams for reuse or wastewater treatment.
MAIN EQUIPMENT & PACKAGE LIMITS
Stripper, reboiler, condenser, reflux drum, pumps, exchangers and feed tank. Materials, design margins, maintainability, isolation, access, lifting and spare philosophy are coordinated with the approved operating cases.
CRITICAL DESIGN INPUTS
Feed assay/composition, design capacity, operating pressure and temperature, product specifications, turndown, utilities, battery limits and site ambient conditions.
ENGINEERING DELIVERABLES
Contaminant balance, stripping design, materials review, PFD/P&ID and emissions interfaces. 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.
AUTOMATION, SAFETY & HSE
DCS regulatory control, critical interlocks, relief and depressuring, gas/fire detection, hazardous-area classification, HAZOP actions and applicable SIS/ESD functions.
APPLICATIONS & PERFORMANCE BASIS
Refineries, hydrotreaters, cokers and sulfur complexes. Capacity, product quality, consumption and emissions commitments are confirmed only after the representative feed and project Design Basis are approved.
CODES, STANDARDS & QUALITY BASIS
API, ASME, NACE and environmental discharge requirements. 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.
CONTRACTUAL CODE BASIS
API, ASME, NACE and environmental discharge requirements.
