PROCESS & OPERATING PHILOSOPHY
Two/three-phase separation, surge, flash, knock-out and reaction support services. The operating sequence, recycle paths, start-up/shutdown cases and normal/turndown behavior are defined before equipment finalization.
PROCESS EQUIPMENT
Pressure Vessels & Drums
UNKA ENGINEERING designs pressure vessels and process drums for separation, accumulation and other refinery and chemical plant duties. Operating and upset conditions, material selection, nozzle loads, inspection access and testing requirements define the equipment package.
MAIN EQUIPMENT & PACKAGE LIMITS
Shell, heads, nozzles, internals, demisters, supports, platforms and instruments. 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
Sizing, separation checks, ASME calculation, drawings, NDE, hydrotest and MDR. 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, gas, chemical, utility and environmental systems. 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 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 and project specifications.
