FLOBLOCK Additive Injector
Skid-Mounted Dual Pump Additive Pressurisation and Storage Systems

FLOBLOCK Additive Injector

Flotech Performance Systems (FPS) manufactures complete turnkey additive and dye injection systems for petroleum and chemical applications.

Having drawn on three decades of experience in additive injection systems to develop the FLOBLOCK, the most advanced additive injection manifold to date, Solifo is proud to partner with FPS in Sub-Saharan Africa.

The FLOBLOCK combines Check Valve, Needle Valve, Flowmeter, Solenoid Valve and Filter in a single manifold which measures < 23cm in length. It integrates with all mainstream load computers, additive controllers, PLCs and Terminal Automation Systems.

Based upon a product flow rate of 2400 LPM, the Standard Flow Injector is suitable for 100 - 3000 ppm (typical shot size of 20 - 200cc). The Low Flow Injector is suitable for 20 - 600 ppm (typical shot size of 10 - 40cc).

FLOBLOCK Additive Injector

Applications:

Marker dyes
DNA markers
Performance additives
Stenching & denaturing agents

Benefits:

The unique design of the FLOBLOCK incorporates features which combined make it the most efficient and reliable injector on the market
Integrated flow control valve allows fine tuning of additive flow and facilitates calibration under true process conditions for more accurate injection rates and reduced additive wastage
Integral filter prevents contamination entering the meter or the solenoid
Inbuilt non-return valve prevents additive contamination caused by reverse flow
One-piece stainless construction and static seals ensures robust, leak-free performance
Common bolting pattern and inlet / outlet positions allow direct replacement of most common injectors (adaptors are available where bolting patterns differ)
Optional dual pulse flow meter provides pulse redundancy to prevent unwanted shutdowns
Optional stainless-steel gears and PTFE seals ensure performance across a diverse range of chemicals and additives

FLOCAL Calibration Device

Flotech Performance Systems has drawn upon 30 years’ experience in additive injection systems to develop the world’s first closed loop additive calibration device - the FLOCAL.

Using the FLOCAL calibration kit (available separately), FLOBLOCK can be quickly, safely and accurately calibrated.

Provides accurate and repeatable calibration without exposing engineers to potentially harmful additives or vapours
Combines inlet diverter valve, calibration cylinder, graduated piston gauge, outlet diverter valve and sample return pump in one compact device
Captures additive in a built-in calibration cylinder from which volume can be read using its graduated piston gauge. Once volume is recorded, the FLOCAL’s integral pump exhausts the contents of the calibration cylinder via a dedicated outlet which can be piped to slops or back to tank

Benefits:

The unique design of the FLOCAL makes it the first true closed loop additive calibration device. Using FLOCAL during calibration makes the process safer, quicker and more efficient
Integrated calibration cylinder with graduated piston gauge in 1cc increments provides more accurate results than using a simple calibration jar
Closed loop design means operators are no longer exposed to potentially dangerous additives
Integrated sample return pump prevents additive used during calibration from being wasted - it can simply be returned to tank
Optional 100cc and 350cc Calibration Cylinders ensure performance across a diverse range of treat rates
Optional Thermal Relief Bypass allows for thermal expansion when the unit is idle, negating the need to purge the system after use

Skid-Mounted Dual Pump Additive Pressurisation and Storage Systems

There are significant advantages to completing as much of the build off-site as possible by delivering a skid-based system solution.

The system can be piped, cabled and flow tested in advance of delivery.
Snagging is done off-site which minimises site assembly and start-up time.
Large skids can be built in modular form to allow road transportation.
Reduced time on site makes the project cheaper, safer and more convenient.
Quality is assured since all welding, pipework and assembly is performed by qualified and experienced personnel.

Additive Pressurising Systems

We specialise in the design and fabrication of pump skids for the pressurisation of additives, hydrocarbons and chemical liquids.
Pressurising pump skids ensure delivery of additive at sufficient differential pressure to allow effective injection into the main product line. Insufficient additive pressure can cause a number of problems including fluctuating treat rate which is costly and results in off-spec products.

By ensuring a sustained additive pressure, the function of the fuel additive systems is maximised, products are delivered on spec and expensive additive losses are avoided. Most of our systems are built off-site in skid form and tailored to suit the specific application, be that pressurising a single additive or a fully integrated system to offload, store and pressurise an additive.

Our skids can be engineered to incorporate a host of options including:

Single or dual/redundant pumps
Motor control and heating
Temperature and flow monitoring
Pressure monitoring
Built in filtration/strainers
Provision for exothermic additives
Integrated offloading or loading
Integrated bunded storage with level monitoring

Additive Injection Systems

Standalone systems are designed to inject one or more additives into a product line, typically using an injection block such as the Flotech FLOBLOCK which is controlled either by an on-skid controller or off-skid PLC or DCS. For larger injection rates, we use our compact piped injector design to provide higher flow rates without the need to significantly increase skid size.

The solutions we deliver are fully customised to suit our customers’ requirements in terms of additive injection rate, footprint and application. We also build stand-alone systems which incorporate additive storage in the ‘mother/daughter’ format.

Our ‘mother/daughter’ skids combine a stand-alone injection system with integrated bunded product storage and extended capacity in the form of an IBC. To fill the integral tank, an IBC is positioned on top of the skid which then gravity drains into the tank mounted on the skid below. This type of design helps avoid the chance of running the system dry and allows tank filling during loading.

We have designed systems which inject during loading and offloading of bulk fuels, as well as when filling and emptying individual vehicles. The projects we have undertaken cover a broad spectrum of applications, from injection of anti-icing additive into jet fuel to biocide treatment during the filling of bus fuel tanks.

Bespoke Skids for Additive Injection and Pressurisation

We help organisations processing industrial liquids and gas to manage additive injection and pressurisation through the design and manufacture of tailored skids. Our systems are custom-engineered to the highest standards to ensure accuracy, reliability and regulatory compliance when it matters most.

Skid-based solutions reduce time on site making the project cheaper, safer and more convenient
Pump skids for the pressurisation of additives, hydrocarbons and chemical liquids
Standalone systems inject one or more additives into a product line
Loading rack-mounted injection systems are found in the majority of fuel terminals
Turbine-driven Injection Systems deliver accurate self-powered additive injection
Dual-pumping technology operates the pumps alternately to extend their life and build in pump failure

Dual Pumping Technology

A unique feature of our dual pump skids is our optional proprietary pump-sequencer with optional handheld controller. The sequencer operates the pumps alternately, extending their life and building in redundancy which is vital in the event of a pump failure. The sequencer automatically starts the standby (redundant) pump should the main pump fail to build or maintain pressure.

Skid-Mounted Containerised Systems

These skid-based systems combine storage, pressurisation and injection/blending within a self-contained system providing liquid and gas processors with a custom-built solution which can be configured to suit a host of additive injection and blending applications.

The transportable nature of the containerised system lends itself particularly to applications where a system is required for a fixed term contract or as a temporary measure for testing of new additives. Once the contract or trial has finished, the asset can be moved to another site or repurposed for another application.

Can be piped, cabled and flow tested in advance of delivery.
Snagging is done off-site minimising site assembly and start-up time.
Large skids can be built in modular form to allow road transportation.
