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 3 rd 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.
Features Arrangements Calibration Kit 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 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 Temperature compensation upgrade option includes preinstalled 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 is supplied as standard with inline strainer containing 80 mesh basket. Automatic Isolation Each of the streams has isolation valve for easy maintenance. 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.
