PROCESS & OPERATING PHILOSOPHY
Total/partial condensation, reflux generation and vacuum-system duty. The operating sequence, recycle paths, start-up/shutdown cases and normal/turndown behavior are defined before equipment finalization.
PROCESS EQUIPMENT
Process Condensers & Air Coolers
Shell-and-tube condensers and air-cooled heat exchangers configured for vapor composition, pressure level, ambient conditions and non-condensables.
AIR COOLER / FIN-FAN
Air-Cooled Heat Exchangers
Forced- or induced-draft Air Coolers provide process condensation and cooling with ambient air, reducing cooling-water demand and integrating directly with column overhead and product-cooling services.
CONFIGURATION
Forced draft, induced draft, horizontal or A-frame arrangements.
DESIGN BASIS
API 661 and project-specific ASME, material and climate requirements.
MAIN COMPONENTS
Finned-tube bundles, plenums, fans, motors, drives, louvers and supporting steel.
APPLICATIONS
Column overhead condensation, gas cooling and intermediate or final product cooling.
MAIN EQUIPMENT & PACKAGE LIMITS
Shell-and-tube or air-cooled arrangement, receivers, vents and drainage interfaces. 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
Thermal design, phase/pressure-drop review, mechanical design and control requirements. 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
Column overheads, solvent recovery, vacuum and refrigeration 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
TEMA, API 660/661 and ASME VIII. 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
TEMA, API 660/661 and ASME VIII.
