Stratco® XP2 technology for the stratco® contactor reactor

The STRATCO® XP2 technology is a Contactor™ reactor enhancement developed to improve the acid/hydrocarbon emulsion flow path near the tube bundle end of the Contactor™. In the current design, emulsion flow leaves the annulus between the Contactor™ shell wall and circulation tube, then immediately turns and enters the tube bundle.

In the XP2 design, the emulsion flow is extended further along the length of the tube bundle and preferentially distributed across the tube bundle. This enhancement allows for more effective use of the tube bundle heat transfer surface area and a decrease in tube bundle wear near the end of the circulation tube.

With XP2 technology, more heat of reaction can be removed allowing the reactor to operate at lower temperatures at a constant feed rate OR at a higher feed rate at a constant reaction temperature. !e more uniform flow regime will reduce maintenance costs and increase reliability of the tube bundle. XP2 technology can be installed in new Contactor™ reactors or retrofitted in the field or shop to any existing Contactor™ reactors with minimal downtime.
