Who we areCTP (Chemisch Thermische Prozesstechnik GmbH) is one of the world’s leading companies in air pollution control for industrial applications.

CTP was founded in 1985 and since then, its engineers, chemists and researchers have been developing individual technologies to serve customers worldwide, covering all industrial sec-tors. At CTP, we adhere to high quality standards maintained by qualified expertise.

What we doCTP can offer you emissions close to zero at a minimized total cost of ownership. We provide integrated solutions from the emission source to the stack for the reduction of contaminants such as volatile organic compounds (VOC), NH3 or NOx.

Our company‘s ecological mission? We aim to convert air pollutants into usable energy.

Where we workWith its headquarters in Austria, CTP has sales networks all over the world with licensees in Australia and Japan, subsidiaries in France, Korea, Spain, Sweden and the US, as well as partners in many other countries.

OXIDATION1 Regenerative Thermal Oxidation (RTO)

Optimal abatement of all organic pollutantsThe waste gas is directed through ceramic heat exchangers into the oxidation system where harmful compounds in the offgas are oxidized without residue. The hot purified air releases thermal energy as it passes through the ceramic heat exchanger beds. This energy is used further in the process resulting in a reduced auxiliary fuel requirement and saving operating cost.

2 Direct Thermal Oxidation (TO)Explosive pollutant compositionsSeveral waste gas streams, liquid or gaseous, lowly or highly concentrated to explosive are injected directly into the combustion chamber and oxidized. The combustion cham-ber can be combined with a scrubber unit and a DeNOx system. The purified air can be directed to a downstream heat recovery.

3 Recuperative Catalytic Oxidation (CO)Defined pollutant compositions in high concentrationsThe waste gases are oxidized without residue whereby special CTP catalysts deter-mine the outstanding cost-effectiveness of the RecuKAT because of their low reaction temperature. Independent of the pollutant concentration an extremely high cleaning efficiency can be achieved.

4 Regenerative Catalytic Oxidation (RCO)Defined pollutant compositions in low concentrationsCombines the low reaction temperature of the catalysts with the characteristics of a regenerative thermal oxidation (RTO).

REDUCTION5 Selective Non-

Catalytic Reduction (SNCR)Removal of NOx

Reduction agents which can either be in aqueous solution, such as aqueous ammonia solution or urea, or gaseous, such as ammonia, are injected into the hot fume gases. This reduces nitrogen oxides and H2O and N2 are formed.

6 Selective Catalytic Reduction (SCR)Removal of NOx with a catalystNOx is converted with a reduction agent to nitrogen and water over a catalyst. The chemical reaction over the catalyst is selective, this means preferentially the nitrogen oxides are reduced while unwanted side reactions of other compounds are inhibited widely.

For small or large waste gas flows, high and low contaminantconcentrations, organic and inorganic pollutants, waste gas streams with or without oxygen. No molecule can escape the finely tuned processes of CTP’s systems. APPLICATAA ION:

ADSORPTION7 Rotary Adsorbers

Large waste gas volumes with low contaminant concentrationsThe CTP rotor concentrates a large flow with low contaminant concentration to a much smaller, highly concentrated waste gas stream. The laden desorption air is then fed into a small thermal or catalytic oxidation system. CTP has developed a patented recircula-tion of the desorption air, resulting in an even higher concentration of the pollutants.

8 Fixed bed adsorptionConcentration peaks or batch processingCTP’s single or multiple fixed beds adsorb the contaminants. During desorption the contaminants are directed to an oxidation system.

High concentration fluctuations of the contaminants in the raw gas challenge the air pollution control system. They can even lead to a complete shutdown of the system when the temperature limits are exceeded. An upstream CTP Smoothing Bed smoothes these peaks.

9 Dry gas scrubbingRemoval of inorganic componentsThe fume gas can contain contaminants such as acids (HCl, HF), sulphur dioxide (SO2, SO3), organic pollutants (e.g. PCDD/DF) or heavy metals (e.g. Hg). For dry sorption the fume gas is first cooled down to the necessary temperature. Then the sorbent such as NaHCO3 or calcium hydroxide and hearth furnace coke (HOK) is added. The contami-nants accumulate on the sorbent which is precipitated efficiently in a downstream dust collector.

ABSORPTION10 Wet gas scrubbingRemoval of inorganic componentsThe hot fume gas from the oxidation is cooled in a quench and then directed to a scrubber system. The scrubbing medium such as water or alkaline or acid solutions is injected at the scrubber head and trickles over the packing material from top to bottom. The inorganic pollutants in the waste gas are absorbed by the scrubbing medium. The purified gas leaves the scrubber over a demister.

FILTRATION11 Mechanical-thermal Filters Removal of sticky dust particles (e.g. tar) and aerosols CTP’s prefilters are filled with high tem-perature-proof packings where particles, tar and aerosols are removed. The filter is thermally restored.

12 Fabric Filters Removal of dust particles Even fine-grained particles are arrested in different filter media, depending on temperature and dust type, and cleaned with jets of compressed air.
