Flare Systems
Elevated flares, small flares, and ground flares for the combustion and disposal of waste gases from industrial plants, supply of complete flare systems including chimney, below-ground furnace, separator, ignition, and monitoring, molecular seal as gas lock, and the required flare burners. Elevated flares as self-supporting, guyed- or framed-steel constructions. Supply of the complete flare system including installation/assembly and commissioning.
Flare Burners
Flare burners depending on the medium or individual application with or without smokeless combustion.
Smokeless combustion may be accommodated with steam injection; three basic types are available as options:
- with injection of internal steam
- with injection of internal-/external steam
- with injection of internal-/external steam and additional steam-air injection
In addition it is also possible to inject air; Ignition of the individual flare burners with individual ignition systems.
Flare Pilot Burners
Ignition by Means of an Ignition Stick:
Ignition of the flare burner by means of a high-energy ignition stick. The high energy required for the ignition is generated by a separate high-energy ignition tool. The ignition tip consists of high-temperature resistant and/or ceramic material; it is designed for a constant operating temperature of about 1200°C. The length of such an ignition stick is available as per requirement.
Gas-electric Ignition:
The ignition of an inflammable gas-air mixture by means of special spark plugs in the pilot head. Each pilot burner has a plug-in connection for the high voltage and one plug-in connection for measuring the voltage of the thermo-elements integrated in the pilot burner. The pilot burners on their part will ignite the flare burner. These pilot burners on their part work with automatic intake suction and are bent towards the entrance of the flare burner; the complete pilot burner and the venturi are each protected against wind by windshields.
Ignition by Climbing Pilot Flame:
Ignition of an inflammable gas-air mixture in the ignition chamber by means of a high-voltage transformer. From there the flame will ascend through a guide pipe to the pilot burners at the top of the flare stack. The pilot burners will, in turn, ignite the flare burner. These pilot burners work with automatic intake suction and are bent towards the entrance of the flare burner; the complete pilot burner and the venturi are each protected against wind by windshields.
Equipment for the Ignition and Monitoring of Flares (controlled from the control cabinet)
Flare Igniters:
Igniters for the ignition of pilot burners with an option of hand-operated ignition on site, operated from a remote site (e.g. measuring station) or for automatic ignition with remote release, e.g. in the event of an outage of the pilot flame. They all have a local display showing the response message from the pilot flame operated through potential-free signalling contacts.
Flare Monitoring Equipment:
Depending on the type of ignition equipment, thermo elements for monitoring the pilot burner flame are available on a regular basis, or they are available with an optional UV flame monitor.
Electric Concomitant Heating
Heating for pipelines, containers, and control panels by means of:
- self-limiting heating bands and heating bands with constant performance (up to ~200°C)
- mineral-insulated heating cables (up to 800°C) single-core heating pipelines of synthetic material with PTFE coating (up to 260°C)
Calculation of the required heat, thermic planning, and dimensioning
Delivery, assembly, and maintenance - all from a single supplier, including the required automatic control engineering, also in the Ex-range.
Steam Concomitant Heating
Heating by means of concomitant pipes or heating plates in various materials in connection with heat-conducting paste. Calculation of heat requirements, thermic planning, and dimensioning - supply, assembly, and maintenance - all from a single supplier.
Heating and Cooling Plates
Prematherm heating plates comply with the required heat capacities and are available in various sizes in C-steel or in stainless steel. The heating plates consist of two metal sheets that are connected by spot welding to form a double-walled plate. These heating plates may be rolled in the factory in order to provide the required diameters from the start, they may then be provided with the required connections for introducing steam- and condensate. It is an advantage of these heating plates that they may be easily assembled by means of strap retainers. No welding work is required; there will be no external pressure on the container wall. Thus no Technical Acceptance or Surveillance (German TÜV approval) will be required for no-pressure containers, and there will be no product pollution, etc..
Prematherm heating plates will safeguard optimum heat transfer; our special heat-conducting paste will level out uneven surfaces so that air gaps between the container wall and the heating plate are avoided.
Heat-conducting Paste
Prematherm heat-conducting paste for concomitant heating systems to improve the heat transfer (11-13 W/mK) between the heat source and the product pipe and/or -container. This elastic and self-hardening heat-conducting paste may be applied easily and quickly as a flat coat, possibly with the help of system sheets. Application depends on the type for temperatures between -200°C and 650°C.
The paste is available in various packet sizes.
Static Mixers
Static mixers for ongoing mixing processes of liquids and gases, without external energy, free of maintenance, available without loose components, depending on the type for temperatures between-200°C and 650°C.
The static mixer consists of a tube casing with elements arranged in tandem for separating the medium flowing through. The products and components to be mixed with each other are separated by a certain number of elements, and then mixed with them. The design depends on the required mixing quality and loss of pressure.
These mixers are deployed in various nominal widths and pressure stages for their mixing jobs (disperse, emulsify, homogenize), chemical reactions (neutralization, halogenization), direct-current solution processes, introduction of gas and/or -air (waste-water treatment, introducing air into fresh water), etc.
They may be delivered in various materials: Steels, stainless steels, synthetic materials or with inner lining.
Agitators (Top-Entry)
Vertical agitators for homogenizing media and/or for preventing sediments in product tanks and basins of all types and sizes for industrial deployment. Two basic variants are differentiated:
- Product Line PS-DIN - The construction components mostly comply with the currently valid DIN standards for agitator constructions (Agitator Drives as per DIN 28130). The fixed and loose bearings of the agitators are located in the lantern. Depending on the mixer variant, the drive bearing will also serve as a fixed bearing, or the movable bearing will be integrated into the sealing unit. The agitators may be freely combined with all available types of drives and seals.
- RS Product Line - This series was developed for medium performance requirements. Within this product line the various drives, seals, and agitator types may be freely combined with each other. You may choose spur gear, flat drive, or bevel-gear drive, but also belt drives or hydraulic motors may be used. To seal the agitator shaft you may use lip seals, gland-flange seals or rotating mechanical seals.
Dimensioning the agitator drives in order to achieve the best possible agitating results will be co-ordinated with our customers.
Side-entry Agitators
Side-entry agitator drives for homogenizing media and/or preventing sediments in product tanks, the maximum performance reaches 55 kW.
Due to the special structure of the drive unit we offer a non-split, absolutely smoothly running impeller shaft with little wear and minimum cost of maintenance. The special structure of our drive units provides an extremely short casing ensuring a very small momentum for the tank wall. Thus no anchoring and no support are required.
The rotating mechanical seal with its design proven over the years is located at the far end of the shaft, i.e. extremely well protected and easy to replace. The bayonet socket seals the drive unit from the tank in a simple manner. All repair work may thus also be carried out with a full tank.
Available with various voltages and motors; also as EX-variant. The following three basic variants are offered:
- SSwivel-arm agitators may be swivelled by 30 ° to either side in order to prevent material from depositing and to avoid sediments in tanks for crude oil
- Fixed variant for homogenizing refinery products
- High-temperature variant may be deployed up to 200 °C, e.g. for bitumen
