HIGH PERFORMANCE TRAYS TECHNOLOGY
Latest Advances And Application For The Hydrocarbon Processing Industries
BARETTI has been founded on 1890 and it is fully owned by the Baretti Family.
Focused on Separation Technologies and Components
since 1950. • Headquarters and Workshop in Italy serve customers
worldwide • The products cover the following unit operations:
o Distillation, Absorption & Stripping o Liquid Liquid Extraction o Reaction o Demisting & Coalescing
NEW HPI PROJECTS TRENDS: HPI Market Data)
• COMPLEXITY. Flexibility , Refining/Petrochemical Integration, Ability to process wide feed slate
• SCALE. Typical new refineries have 300.000 to 600.000 bpsd capacity.
ADDED VALUE OF INTEGRATED GASOLINE AND AROMATICS LARGE SCALE PLANTS
Easier integrated process control Capex Optimization Opex Optimization
Reliable Easy to install Low cost relative to other device
DISTILLATION COLUMN STILL SHAPE THE LANDSCAPE OF HPI PLANT
• Column internals size the shells, trays are still the dominant internals
• Capital cost of HPI projects rise + cost consciousness increase = Projects Components Optimizations
Reliable Easy to install Low cost relative to other device
OBJECTIVE OF A HP TRAY: • Maximize vapor/liquid contact and
throughput with minimum pressure drop, weeping and entrainment
• Obtain a liquid plug flow on tray to enhance
Mass Transfer
HOW TO DESIGN A HPT • Area Under DC • DC Inlet Shaping • Flow improvement on tray
• Vapor disengagement • Process / mechanical balanced design
Reliable Easy to insOtall Low cost relative to other device
HOW - AREA UNDER DC
• Sloped DC design Improvement • Higher DC Capacity • Short TS in large
columns
