Industrial waste - Import export

Rotary kiln incinerators are the workhorse of industry to burn solid waste in combination with sludge, waste gas and/or waste liquids and where the rotating motion transports the solid burning waste through the incinerator. Ashes are collected at the end of the rotating kiln and then combustion gases are completely oxidised in the static post combustion chamber. Rotary kiln incinerators typically feature different types of solid waste feeding systems for the bulky solid waste, containers and drums such as feeding screws and ram feeders. Waste gases and liquids are either injected into the rotary kiln, or the (vertical) post combustion chamber behind the rotary kiln. It provides for flexible and versatile incineration technology, but is characterised by a lower thermal efficiency with the associated higher operating and maintenance costs. Key Features Rotary kiln furnace with pre-set inclination and variable rotation speed. Labyrinth type seal with cooling and/or flushing with inert gas Different feeding systems for solid waste, waste liquids and waste gases Can be operated in a reducing or oxidizing environment Different drive mechanisms such as chain or direct drive, depending on the size of the kiln and the capacity Key Advantages - Robust and flexible design to burn a wide range of waste fractions – Proven technology – Destruction efficiency over 99.999% and less than 3% carbon in the ashes – Low NOx and CO emissions possible – Flue gas treatment train needed to meet acid, heavy metal, dust and PCDD/F emission levels

Enclosed ground flares are suitable for thermal destruction of a wide range of waste gases including rich and lean gas mixtures. Where the burners are housed in a cylindrical vessel resulting in the combustion process being out of sight and more controllable in comparison to elevated flares. Enclosed ground flares can also be designed with or without temperature control. With temperature control, a minimum residence time, at a specific combustion temperature can be set and guaranteed. Consequently, temperature controlled ground flares, also called combustors or thermal oxidisers, can meet the most stringent emission values. The emissions can be monitored with chemical emission monitoring (CEM) units. Features Can be equipped with Europem’ proprietary Tulip Venturi Burner for the combustion of lean waste gases or with multiple burners designed for the flaring of large capacities (modulated flaring is possible) Operating at varying temperatures depending on the load of the ground flare Smokeless operation and high destruction efficiency by ensuring some turbulence around the flame and sufficient residence time at elevated temperatures Simple control system, because the combustion temperature is allowed to fluctuate Provisions for support fuel in cases of combustion of lean waste gases or cooling air in cases of rich waste gas combustion Can be supplied as natural draft or forced draft system Can be supplied with or without temperature control Advantages No visible flame and reduced visibility of the installation due to lower stack heights Reduced noise levels Minimal heat radiation Possibility for emissions sampling High destruction efficiencies and smokeless operation Applications Tank farms and ship loading terminals Chemical and petrochemical industries Food processing industry Waste management plants

Industries will generate Low CV waste gases, which are either difficult to burn or can contain insufficient energy to self-sustain the combustion process. For these applications, Europem developed the proprietary “ring-of-fire” Flare Tip. This tip has a ring of flame around the central waste gas tip thus ensuring complete oxidation of the low calorific waste gas. Both air assisted and non-assisted flare burners are available. Key features Proprietary design of HP sonic gas nozzle which maximises the entrainment of ambient air into the combustion zone Wind shield placed around the HP gas nozzles to prevent flame pull down Use of high grade alloys to enhance lifetime of the flare tip. Key advantages Smokeless operation at low heat radiation 100% smokeless turn down possible for air assisted HP flares Lower flare stack heights No need for any assist medium A low pressure flare can be integrated with the HP sonic flare to provide both HP and LP gas flaring in a single flare tip. Suitable for smokeless combustion of waste gas with entrained liquids Applications Upstream oil & gas sector Chemical and petrochemical industries including refineries Pipeline transport LNG and NG terminals and compressor stations

Utility Flares (Pipe Flares) are the most basic flare design available, to provide a robust, reliable and flexible solution for the flaring of large volumes of low pressure waste gas when smokeless operation is either not required or can be achieved without an assisting medium (like steam, air or gas). Reliable operation at both full load and partial load is possible. Key features Flame holders fitted on the periphery of the flare tip ensure stable operation. These flame holders provide a zone of recirculated flue gases, which prevent flame lift off, from the flare tip. Wind deflectors to prevent flame impingement, which prevent a low pressure zone, downwind of the tip. Pilot burner arrangement to further stabilise the flame. Use of high grade alloys to enhance lifetime of the flare tip Use of dynamic seal to reduce purge gas requirements and prevent flash back. Key advantages Low investment and operational costs Low maintenance costs with the use of high grade alloys and the robust design. Reliable and stable flaring in a wide range of operating conditions Large turn-down ratio Applications Upstream oil & gas sector LNG terminals and NG compression stations Chemical and petrochemical industries including refineries Food processing industries Municipal solid waste treatment (biogas and landfill gas) plants Temperature controlled combustors and thermal oxidisers.
