Proper design of mass transfer internals in the FCC flue gas scrubber can help reduce PM emissions

The EPA’s New Source Performance Standards (40 C.F.R. §60.100-1-0, subpart Ja) regulates refinery particulate emissions, including the discharge of catalyst fines from the FCCU flue gas scrubber stack. Because refiners have traditionally correlated particulate matter (PM) emissions with FCCU cokeburn, high flue gas stack PM can result in reducing severity or throughput in the FCCU at a potentially huge economic cost. The proper selection of mass transfer internals in ...

Safeguard packed column efficiency with proper liquid distribution

Initial liquid distribution directly affects the efficiency of structured and random packing beds. As such, some form of flow test should be conducted to validate distributor performance prior to column startup. Steady state water flow testing is the most common method of testing distributors. It can be conducted in the shop or in the field to verify the design, manufacture and installation. Three Common Types of Liquid Distributor Flow Tests • Liquid Range Test with ...

Separator technology reduces refinery operating costs and downtime

A US refining company contacted us to discuss a separation problem in the feed to an alkylation process. Caustic entrainment from their selective hydrogenation unit was poisoning the hydrofluoric acid catalyst in the alkylation unit. The continuous phase feed to the alkylation unit consisted of ~180m3/hr of mixed C4 hydrocarbons, mainly butanes and butylenes, with varying levels of 10 – 20% caustic solution entrained as a dispersed aqueous phase. Sulzer was commissioned ...

Seven reasons why maintenance managers choose HVTS vs HVOF

1. Market Recognition - 2. Porosity & Oxides Level - 3. Production Rate - 4. Variable Thickness - 5. Refurbishability - 6. On-site Safety, Quality, and Environment Protection - 7. Project Management.

Tracerco Diagnostics™ Distribution study - FCC stripper

Uniform distribution of catalyst and steam in a stripper is critical to achieve high stripping efficiency (less carry-down of hydrocarbon products from reactor to regenerator). A failure to effectively remove hydrocarbon from the catalyst will result in a loss of product, lower throughput, and lower catalyst activity due to increased regenerator bed temperature. The Field Test Tracerco was contacted to conduct distribution studies for a leading refiner that was experiencing ...

Tray design features that reduce turnaround maintenance time

Column shutdowns can be costly. Production is halted and maintenance expenses accumulate without any offsetting revenue. Maintenance crews need to isolate, open, inspect, modify, repair, and close columns, all under pressure to complete work as expeditiously as possible. Minimization of shutdown costs begins during the equipment design phase. Sulzer incorporates several features into our tray designs that can reduce column shutdown time. Tray Replacement and Installation Tray ...

When reliable operation and easy inspection is key

Topsoe’s outlet collector is easy to install and inspect and help ensure even flow distribution in the bottom of the reactor. It is important to have the best catalyst to ensure optimal performance of your hydroprocessing unit. However, it is equally important to have the best reactor internals to ensure the optimal flow conditions for the catalytic reactions in your reactor. Topsoe’s outlet collector ensures even flow distribution in the bottom bed thereby maximizing ...

Why do many crude/vacuum units perform poorly?

In many cases it’s because the original design was based more on virtual than actual reality. There is no question: computer simulations have a key role to play but it’s equally true that process design needs to be based on what works in the field and not on the ideals of the process simulator. Nor should the designer simply base the equipment selection on vendor-stated performance. The design engineer needs to have actual refinery process engineering experience, not ...

Why produce diesel from the vacuum unit?

Look ahead five years. The economy is likely to keep tightening and the rush to control pollution will inevitably be accompanied by demands for greater energy conservation. Consequence? A growing market for diesel which yields more energy per unit volume. Yet many continue to believe that producing diesel from the vacuum unit is poor design—that it should be produced only from the atmospheric column. Hence many refiners feed 20-30% diesel boiling range material to their ...
