The ZHB Distribution Baffle is used for distribution within a separator where there is a high solids loading, a waxy crude or a chance of fouling.

The ZHB Distribution Baffle assembly is fitted shortly downstream of the correctly designed inlet device in a 2-phase gas / liquid, or 3-phase, horizontal separator, to complete the inlet-processing zone.

From the inlet of the separator, the bulk liquids from the inlet device fall under gravity through a space within the inlet-processing zone, into a region bounded by the vertically mounted ZHB Distribution Baffle; the purpose of the distribution baffle is to quieten the liquid flow prior to its entry into the liquid / liquid separation region, thus maximising liquid /liquid separation.

In a horizontal separator, dependant on the application, the baffle offered is usually a full cross sectional assembly and as such, the baffle also has an extremely important part in enhancing the gas distribution through the separator, minimising mal-distribution on the downstream demisting equipment, thus maximising gas / liquid separation. Perforated type baffles have a tendency to suffer from clogging, but due to its large openings, the ZHB distribution baffle does not suffer from solids blockage and as such is ideal for any “dirty” duties.

Dependant on the application, flow regime, slug volume, physical properties and the physical size of the separator, further Z-series baffles (calming baffles) for use where there is a high solids loading, a waxy crude or a chance of fouling can be added downstream of the inlet-processing zone, to enhance the flow distribution and to give a high degree of surface control on the gas / liquid interface. Information on these baffles may be found within our “ZVB Calming Baffle : Product File”.

Advantages of the ZHB Distribution Baffle:

• Distributes and calms fluids efficiently.
• Does not suffer from fouling or clogging
• Low / medium installed cost.
• Various materials.
• Low pressure drop.
• Reduces turbulence and re-circulation within the liquid section, effectively promoting gravity separation.
• Provides a pressure drop within the gas phase area, thus effectively distributing the gas flow evenly over the downstream demisting equipment, minimising any mal-distribution.
• Effectively handles slugs and surges.
• Easy to install in existing separators.
• Wide operational range 100% - turndown.
• No moving parts thus no maintenance.
