Optimisation of Hydrocarbon Cracking Units

The “Cracking” of high molecular weight hydrocarbons into more valuable, low molecular weight compounds using a Fluidised Catalytic Cracking Unit (FCCU) is a key process operation in our customers refinery processes and Tracerco fully understand that the efficiency of this process can have a dramatic effect on the financial and environmental performance of the overall refinery. That is why we have developed and carried out on our customers facilities a number of TRACERCO™ Diagnostics - FCCU Studies, which utilises novel tracer technology (vapour, liquid and solid), so that the overall performance of our customers FCCU’s can be understood & optimised.

The TRACERCO™ Diagnostics - FCCU Study is able to investigate and measure all the following process operational conditions:

• Vapour & Catalyst Riser Velocities:
• Vapour to Catalyst Slip Ratio in Riser;
• Plug Flow of Vapour & Catalyst in Riser;
• Vapour & Catalyst flow distribution / residence time in reactor;
• Catalyst Flow Profile in Stripper;
• Distribution of Stripping Steam in Riser;
• Catalyst Regenerator Residence Time;
• Cyclone Efficiency;
• The Density Profile in the Riser / Catalyst Stand Pipe;
• Reactor / Regenerator Level Profiles;
• The Channelling of Vapour in Reactor;
• The Detection of deposits in Reactor Overheads;

Features of the TRACERCO Diagnostics™ - FCCU Study

• A rapid, accurate, safe and reliable method of characterising the various process conditions that exist within a fluidised “Cracker” and the associated transfer pipes.
• A study which is undertaken by a team of highly trained and skilled process engineers.
• A technique which uses tracers able to mimic the flow of liquids, solids and gases.
• A non-intrusive measurement technique which places the detection devices on the outside of the vessel.
• Rapid response available from Tracerco.

Benefits of the TRACERCO Diagnostics™ - FCCU Study

• Confirms the actual operating conditions within the FCCU allowing our customers to optimise its performance.
• Identifies if losses (catalyst) are occurring from the FCCU unit.
• Enables customers to optimise maintenance strategy for the FCCU (deposit build-up, losses)
• Greater understanding of production rates relationship with process performance data.
