Multi-Stream Blender

Advanced solutions for Bio-fuel blending applications The Multi-Stream Blender utilizes the latest advancements in microprocessor technology, to bring unparalleled accuracy to blending system solutions with features such as multiple target blend percentages, user definable alarm outputs, self calibrating functionality, and clean arm flushing. The Multi-Stream Blender can be configured in several arrangements, allowing for up to four streams per assembly. Utilizing the Honeywell Enraf designed hydraulic actuated V-port flow control valves the Multi-Stream Blender is capable of achieving highly accurate linear control across the complete blend range.

The Perfect Blend With energy costs spiraling upwards, and elevation of environmental issues on the global agenda, the majority of oil companies are now seeking to capitalize on the expansion of blended bio-fuels at the load rack. Honeywell Enraf developed today’s standard for load rack blending, starting in the 1980’s for ‘Mid Grade’ fuels. During the 1990’s Honeywell Enraf extended its expertise to Ethanol blending at the load rack and today has the most advanced solutions to blend custom grades of Ethanol and Bio-Diesel blended fuels. The design of Honeywell Enraf’s blending skids takes into consideration the various issues for adding an Ethanol or Bio-Diesel blending capability to the load rack: • The need for a small foot print blender. • The requirements for accurate measurement and tight ratio control of Ethanol and Bio-Diesel. • Temperature compensated total for blend components. • Fast and simple meter proving. • Easy interface to existing load rack controls. • The flexibility of multiple blend ratios.

Seamless Integration The design philosophy behind all Honeywell Enraf additive injection and blending systems is to ensure that every application can be catered to. Regardless of whether the loading facility has single or multiple arms, the requirement for seamless integration with load rack computers, Terminal Automation Systems and a multitude of 3rd party equipment is paramount. This seamless integration capability is further enhanced by Honeywell Enraf’s provision of all peripheral equipment like additive offloading pump skids, additive storage tanks, additive boost pump pressure skids, containerized additive units and portable injection equipment.

Blend Product Supply The Multi-Stream Blender requires a pressurized product supply. Typically 15 - 20 psi differential pressure is required across blend product supply & main product flow pressure.

Hand-Held IR Controller The hand-held Infra-red remote controller is a tool used to interface with the Multi-Stream Blender, allowing tasks such as the adjustment of parameters, resetting of alarms and calibration of the blender. The same hand-held is capable of communicating with all Honeywell Enraf additive and blend controllers therefore it is not necessary to have a controller for each blend unit.
