PROCESS & OPERATING PHILOSOPHY
Fractionation, absorption, stripping, extraction or wash service as required. The operating sequence, recycle paths, start-up/shutdown cases and normal/turndown behavior are defined before equipment finalization.
PROCESS EQUIPMENT
Distillation Columns
Purpose-built separation vessels with coordinated hydraulic, mechanical and fabrication engineering.
MAIN EQUIPMENT & PACKAGE LIMITS
Shell, heads, nozzles, manways, internals, platforms, ladders and supports. Materials, design margins, maintainability, isolation, access, lifting and spare philosophy are coordinated with the approved operating cases.
CRITICAL DESIGN INPUTS
Design/operating cases, fluid properties, corrosion allowance, materials, nozzle loads, wind/seismic data, transport limits, insulation and maintenance clearances.
ENGINEERING DELIVERABLES
Hydraulic rating, mechanical calculation, fabrication drawings, ITP, NDE and data book. 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
Code-compliant relief interfaces, access and lifting provisions, inspection hold points, material traceability, qualified welding, NDE and pressure/leak testing.
APPLICATIONS & PERFORMANCE BASIS
Refinery, chemical, solvent, alcohol and gas-processing services. Capacity, product quality, consumption and emissions commitments are confirmed only after the representative feed and project Design Basis are approved.
CODES, STANDARDS & QUALITY BASIS
ASME VIII, API 520/521 interfaces and project specifications. 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
ASME VIII, API 520/521 interfaces and project specifications.
