Minimum requirements fr all types f gases Dew-pint at bar abslute : drier than -65 C Hydrcarbns (expressed as CH 4 ) : < 20 ppm vlume Fren r similar chemicals : nne Particle size : < 0.01 m Temperature : 5 C t 40 C / 41 F t 104 F Inlet pressure: - Fr air feed gas : 3 t 8 barg / 45 t 115 psig - Fr xygen feed gas : 2.5 t 8 barg / 35 t 115 psig Oxygen frm a VSA/VPSA/PSA system Oxygen : 90 t 93 % by weight Nitrgen : 5.1 t 1.9 % by weight Argn : remainder VAS/VPSA/PSA systems are t be ptimised in rder t assure a cnstant residual nitrgen cntent in the feed gas as required by the layut specificatin f the zne generatr unit. Oxygen frm a LOX system Oxygen : 98 t 100 % by weight Remainder : nitrgen and argn N.B.: A minimum nitrgen cntent in the feed gas t the zne generatr is necessary in rder t ensure ptimum perfrmance and cnstant, lng-term, zne generatin. If the nitrgen cntent is belw 0.2 % by weight, nitrgen gas must be added t the feed gas. 5

6 Nitrgen Gas Specificatin Oxygen frm a LOX surce des nt cntain sufficient nitrgen t ensure ptimum perfrmance. An average nitrgen cncentratin f apprximately 2.3 wt% is required and this has t be adjusted depending n the actual perfrmance layut f the zne generatr. Essentially there are three methds dsing nitrgen t the main gas feed t the zne generatr. The methd chsen depends n the size f the plant and the level f peratr cmfrt required: Nitrgen gas frm a high pressure strage cylinder (small applicatins) Nitrgen gas frm a liquid surce (medium / large applicatins) Dry air frm a small cmpressr / dryer unit (medium / large applicatins) Nitrgen gas Nitrgen purity : > % vlume (type 4.6) If nitrgen is selected, special attentin must be given t the dew-pint and the hydrcarbn cntent necessitating the use f high purity nitrgen. Dry air It is als pssible t use clean, dry, il-free air. Special attentin must be given t the selectin and design f the cmpressr/ dryer unit. The nitrgen gas r dry air must cmply with the given Minimum Requirements fr feed gases. COOLING WATER SPECIFICATION A small amunt water is required fr the cling f the zne generatr unit. In rder t ensure adequate cling the water shuld have the fllwing specificatin: Cling medium : Water Inlet temperature range : 4 t 35 C / 36 t 95 F Temperature rise ( t ) : 5 C / 9 F Inlet pressure : 2 t 6 barg / 29 t 87 psig Water quality : drinking water r equivalent ph : 6 t 8 Chlride cntent : < 100 mg/ltr Cnductivity : < 500 S/cm Ttal suspended slids : < 50 mg/ltr Particle size : < 0.5 mm / 0.02 Fe / Mg cntent : < 0.3 mg/ltr Hardness : < 2.68 mml/l* * 2.68 mml/l = 15 dh r 26.7 fh r 18.8 eh r 267ppm (mg/l) SCOPE OF SUPPLY The OZAT zne generatrs are supplied as fully assembled and tested units. The scpe f supply includes: The zne generatr tube(s); the pwer supply t the zne generatr; all internal piping and fittings; all internal wiring and cnnectins and the enclsure fr the equipment. Nt included is all that is nt specifically mentined, such as: The feed gas supply; the zne cntacting system; installatin and cmmissining; etc.. 6

7 APPLICATIONS The OZAT units have been designed fr universal applicatin and, depending n the selected ancillary equipment, can be easily integrated in t all types f prcesses. Sme examples are: Drinking water plants Waste treatment Recycled water plants Fish farms Swimming pls Washing in the fdstuffs industry Influent water treatment Cling systems and twers Dedrisatin Intermediate xidatin Labratry applicatins Pure water, etc. In many cases the applicatin determines the ancillary scpe f supply. ANCILLARY SUPPLY Unless therwise agreed, the OZAT zne generatrs will be supplied as units that have t be cmplimented with ther ancillary equipment in rder t create a functinal plant. Basically, an zne installatin can be brken dwn in t the fllwing sectins: Ozne generatr prper Feed gas equipment Cntacting system Ozne destruct unit Measuring instruments Ambient surveillance Feed gas equipment There are 3 main types f feed gas systems fr zne generatr plants: Air preparatin with cmpressr and dryer Pressure swing adsrptin (PSA) with cmpressr and xygen cncentratr Liquid xygen (LOX) with nitrgen admix system Air preparatin system made-up frm: Article N. 1 Cmpressr Scpe f supply: - Cmpressr - Mtr - Air receiver with aut drain - Filters 1 Air dryer Scpe f supply: - Desiccant clumns & cntrl system - Inlet filter (MF) - Outlet filter (AK) 1 Feed gas filter Retentin rate f particles > 0.01m : % 7

Nt Oznia supply Nt Oznia supply 1 LOX tank system Size, layut, scpe f supply, etc. t be determined by the plant peratr and the LOX supplier. 1 Nitrgen surce Size, layut, scpe f supply, etc. t be determined by the plant peratr and the nitrgen supplier. 1 Set f fittings fr the nitrgen/air admix gas Made-up frm: - Pressure reducer - Flw cntrl - Nn-return valve - Slenid islatin valve 1 Feed gas filter Retentin rate f particles > 0.01m : % Pressure swing adsrptin (PSA) sytem made-up frm: Article N. 1 Cmpressr Scpe f supply: - Cmpressr - Mtr - Air receiver with aut drain - Filters 1 Oxygen cncentratr (PSA unit) Scpe f supply: - Desiccant clumns & cntrl system - Inlet filter - Outlet filter 1 Feed gas filter Retentin rate f particles > 0.01m : % Cntacting equipment After the zne has been prduced it is necessary t intrduce it t the prcess. The bject f the cntacting system is t create a large cntact area between the zne cntaining gas and the medium being treated s that there is the highest pssible mass transfer f zne t medium. There are 2 main ways f intrducing zne: Ozne Injectr System: Depending n the service parameters, there are several ways f intrducing zne with an injectr. Hwever, in rder t establish stable cnditins fr the injectr system, Oznia suggests that a small side stream is used as the mtive flw fr an injectr which draws in the zne gas being prduced by the OZAT. An injectr system has the advantage that the system pressure can be maintained and the mass transfer cefficient is very high. 1 Injectr 1 Mtive water pump N.B.: The abve specified cmpnents are typical. The injectr unit and the mtive water pump must be dimensined, in each and every case, t suit prcess cnditins such as line pressure, etc.. 8

9 Prus Diffuser System Prus diffusers are munted at the bttm f the cntact chamber thrugh which the zne gas can be intrduced as small bubbles: Article N. 1 set Prus diffuser After the mass transfer has taken place, bth systems require a reactin vlume/time t enable the required reactins t take place. Typically, the height f these chambers is between 4-6 metre and the vlume depends n the prcess in questin. Ozne destruct unit Exhaust gases frm a prcess nrmally cntain small amunts f un-reacted zne. Befre this exhaust can be vented t atmsphere it is necessary t decmpse these traces f residual zne. When selecting the vent zne destruct equipment it is essential t ascertain if the cntact chamber is abslutely gas-tight f if there is a pssibility f leakage. If the chamber is un-tight, r if there is dubt regarding the gas-tightness, then it will be necessary t install a vent gas extractin fan.
