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 todays standard for load rack blending,
starting in the 1980s for Mid Grade fuels. During
the 1990s 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 Enrafs 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 Enrafs 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.

Features
Arrangements
Honeywell Enraf offers multiple configuration and flow rate
designs for the Multi-Stream Blender. Some examples are
the customized 6-stream horizontal Bio-Diesel blend skids
or 2-4 stream vertical Ethanol blend skids. For alternative
(e.g. slave configuration without the smart Micro-blend
controller, etc) or customized arrangements please contact
your local sales office.
Valve Control Hydraulic Power-Pak
The Multi-Stream Blender is provided with a Hydraulic
Power-Pak (HPP) for valve control. The HPP stabilizes valve
control pressure, solving issues with high viscosity products
(over 50cst) and reducing the pressure differential required
across the blender (15 psi). The HPP is a completely self
contained unit including hydraulic tank, pump/motor and
control tubing and is designed for use in Class 1, Div 1
hazardous areas.
Temperature Compensation
Temperature compensation upgrade option includes pre-
installed temperature transmitters and compensation
software features. Temperature compensation is available
via API tables, specific gravities, or co-efficient of expansion
techniques.
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.
Calibration Kit
To aid calibration of the Multi-Stream Blender, proving
connections are pre-installed in the blend unit, with a single
connection for volumetric proving or dual connections for
master meter proving.
Comms Mini-Pak Emulation
The Multi-Stream Blender contains a communications
emulator that allows the blender to be operated as if it were
a Mini-Pak injection system. A typical application would be
direct communications to an Accuload or Honeywell Enraf
1010 load computer: The Accuload/1010 could be configured
to communicate with a Mini-Pak injector and connected
to the blend controller on RS485. When an additive recipe
is selected, this will be translated in the blend controller
as a blend percentage; the blend controller will operate
normally and upon completion upload the blend totals to the
appropriate load computer registers.
Filtration
The Multi-Stream Blender is supplied as standard with inline
strainer containing 80 mesh basket.
Automatic Isolation
Each of the streams has isolation valve for easy maintenance.
