2018 January PraxEidos Srl GAS RECOVERY UNITS 4 Solvent Recovery Unit The Thecnology Provided The Need PraxEidos s has developed the technology to reduce pollution from A responsable approach fowards protecting the enviroment The obvious choise of a cooling medium is liquid nitrogen which a number of industrial activities using a cryogenic condensation. means limiting the emissions of volatile components. can provide cooling down to -180 ° C. New laws and attitudes to enviromental protection are driving down One method is the condensation of these components by cooling The disign of the heat exchangers poses a special challenge which the permissible level of emission of volatil organic compounds ( VOC’s ). the exaust stream with liquid nitrogen. As the vapours are is beyond the remil of typical heat exchanger design packages. The aim is to reduce the damage that VOC’s cause to human healt and cooled, the volatile components condense and than freeze. Not only are the temperature outside the normal parameters but enviroment.Many of these substances are cancinogenic and These solid particles can be trapped leaving a clean stream of gas the heat transfer relationships have to consider the boiling and causephotochemical smog. to vent to the atmosphere. gas heating of nitrogen, and the condensation and freezing of The neatest and cleanest way to remove VOC’s from exaust gas stream The understanding of the heat transfer mechanism has promoted multiple volatile components in an incondensable stream. is condensation with liquid nitrogen. special heat exchanger geometries which are best suited to be PraxEidos has developed computer design tools to model these The technology from PraxEidos removs VOC’s to meet emission level properties of boiling nitrogen and condensation of gases within heat transfer mechanism and generate valid heat exchanger lower than 20 mg/Nm 3 as well as overcoming the limitations of incondensable vapours. designs. traditional control methods. The temperature required to meet acceptable emissin standards of the order of tens parts per million (ppm) are typically -100 ° C and lower. The Benefit Cryogenic recovery system , designed and supplied by PraxEidos, combines the refrigeration power of liquid nitrogenwith the inerting properties of gas nitrogen resulting in a skid mounted VOC’s control system that is simple to install, economical and effective. Running costs are reduced to a minimum by the ability to reuse the nitrogen to purge and blanket pipe work and tanks. Recovered VOC’s can often be reused directly – something that is more difficult with carbon bed technology and impossible with incinerators and catalytic oxydisers. PRAXEIDOS S.r.l.

2018 January PraxEidos Srl DEOXO UNITS 9 In the Deoxo reactor, the oxygen content in nitrogen combines with hydrogen to form water. The reaction leads to an increase in temperature which is depending o the starting oxygen content. To remove the moisture generated, the gas is passed through the drying section consisting of two adsorbent beds filled with activated alumina.The beds work in alternative to allow for the regeneration. Final dew point of -70 ° C can be easily obtained.

2018 January PraxEidos Srl HYDROGEN ON SITE GENERATOR 10 HYSYS technology is based on a solid polymeric anion exchange membrane to produce pure hydrogen and oxygen. HYSYS can produce up to 4000 Nl/h (66,6 Nl/min) of gaseous hydrogen from a 3% in weight water solution of potassium hydroxide. Internal water tank can be filled when HYSYS is on function. Gases are delivered separately. Oxygen is vented through water return pipeline and hydrogen from its hose. HYSYS can resist up to 20 bar (290 psi) of internal pressure avoiding the need of a gas compressor for gas storage at this nominal pressure. 30 bar (424 psi) are available as option. The minimum hydrogen purity is 99,9% without any dryer or purifier cartridge. HYSYS – Hydrogen Generator Better performance can be achieved using a water dryer.
