Multi-level exhaust air purification for the manufacture of pharmaceutical product agents

08-01-09 For the pharmaceutical product manufacturer with a long tradition, what mattered was the replacement of those exhaust air combustion elements which were no longer up to the state of technology. In that the factory is located in the immediate vicinity of a residential area, the limit values of TA Luft or the 17th BimSchV must be undercut by a considerable amount.

Packed bed filter for the separation of hydrogen flouride (HF) in the ceramics industry

07-11-26 Due to the installation of a new production line, the Japanese manufacturer of technical ceramic was forced to clean ensuing exhaust gasses. This has to do with the fluorine compounds contained in the raw material and expelled during the burning of ceramics in through-type furnaces, which are emitted as hydrogen fluoride (HF).

ROXITHERM Regenerative thermal oxidation (RTO) for the mechanical-biological treatment of waste (MBT)

08-01-09 For a german plant for mechanical biological treatment of waste(MBT), the high demands of the 30th BImSchV with regard to emission values must be complied with. Continuous emission measurements monitor a maximum emission exceedance of 96 h/a. Additionally, an official requirement for a minimum dwell time in the combustion chamber of 2 s exists.

Regenerative Thermal Oxidation at Green Anode Plant

12-02-02 For the production of primary aluminium, carbon anodes are required for the electrolysis process. These anodes are usually produced on the same site as the primary aluminium.
The production of Anodes is splitted in raw material handling / forming and baking. The raw material and forming step is performed in a so called Green Anode or paste plant. At the several steps of processing, VOCs, PAHs and tar/condensates are emitted, which have to be treated with a suitable fume treatment system.

Regenerative Thermal Oxidation with downstream dry scrubber for HF sorption

12-02-08 Our customer is operating coating lines for the production of special coated fabrics at its facilities in Germany and Scotland. VOCs and especially fluorinated VOCs are emitted from the dryers of the coating lines, which requires a combined air treatment (oxidation of VOCs and dry scrubber for HF absorption).

Regenerative Thermal Oxidiser (RTO) with downstream SCR-DeNOx for Carbon Fibre Production

12-02-07 A world-wide producer of Carbon fibres has extended the production capacity at his site in Scotland.
Experiences with existing Regenerative Thermal Oxidisers (RTOs) have shown, that a single unit is not able to meet the low emission levels, especially for Hydrogen Cyanide (HCN) and Ammonia.
Therefore a new concept / technology was required.

Thermal oxidation with regenerative heat recovery (RTO) for GFK production

07-11-26 During the first work-step in the manufacture of ship hulls out of GFK, the negative mould forms are coated with a layer of gel coat in a spraying process. Correspondingly, relatively high concentrations of the solvent, styrol, escape in the exhaust gas, which must be cleaned according to the provisions of TA-Luft.

Thermal oxidation with regenerative heat recovery (RTO) for flexo-printing (packaging)

08-06-26 Whether UV hardened colours, water colours or WetFlex, the use of solvents was reduced in the past years thanks to many innovations. On the other hand, there are many areas in the field of flexo-printing in which the use of solvents could not be dispensed with. The challenge is to clean the ensuing emissions to the official limit levels with the lowest possible operating costs.

Thermal oxidation with regenerative heat recovery (RTO) for foam rubber production

07-11-26 In order to prevent odour emissions from escaping to the neighbourhood and for compliance with official limit levels, exhaust gasses from multiple vulcanisation channels must be cleaned. Due to the tendency towards condensate formation of softener vapours, the systems would have to be laid out in such a manner that they could be operated without manual intervention for the cleaning work.
