QUALITATIVE ASSESSMENT

• Added value in every project:

Acona Flow Technology can offer qualitative assessment of the separation

efficiency based on fluids present and the given process design

• Our services comprise, but are not necessarily limited to the following:

• Equipment and in-line instruments capacity and efficiency verification

• Troubleshooting and incident investigations

• Debottlenecking and/or process constraints identification

• Review of third party technical documentation

• Review of process control and process safeguarding systems

• Utility capacity verification and chemical consumption

• Support to HAZOP studies

• Investigate if there is a

potential for liquid/droplet

carryover from the scrubber

– Analysis of the mechanisms

that can produce free

droplets in the scrubber

• If so, propose and show

solutions that will reduce

the problem

– E.g. introduce internals

HEAT EXCHANGERS

• Experience from evaluation of several heat

exchangers for Fjell, Framo and other

customers

• Alternative geometries simulated and

optimised

• Line sizing and pressure drop predictions

• One project involved design optimisation of

a complete system comprising multiple heat

exchangers with two-phase flow on both

shell and tube side

• Often requires a combination of softwares:

• CFD

• Olga

• Leda

• PVTsim

• Regime map generator
