Flow Distribution Solutions by B.F.S

Optimized Flow for Maximum Reactor Efficiency

In heterogeneous catalytic processes, uniform flow distribution is critical for achieving optimal contact between reactants and catalyst surfaces, minimizing pressure drop, and maximizing process efficiency. At B.F.S, we provide engineered flow distribution systems designed for fixed-bed reactors, adsorption towers, and catalytic converters—ensuring reliable and efficient operation under demanding industrial conditions.

What Is Flow Distribution?

Flow distribution refers to the even and consistent spread of gas or liquid across the entire cross-section of a packed bed or catalytic surface. Poor flow distribution can lead to:

➖ Channeling
➖ Hot spots or cold zones
➖ Premature catalyst deactivation
➖ Reduced conversion efficiency
➖ Uneven bed utilization

B.F.S flow distribution systems mitigate these issues through precisely engineered internals and tailored flow management strategies.
