    in the Pressroom

  • Carbon-neutral Printing in Practice Certification possible Limited quantity of accredited certification auditors The procedure is the same in most of the cases: - Calculation of the CO2-consumption - Purchase of certificates for compensating the CO2-emissions - But no support for reducing CO2 emissionsCorrect way: CO2-Reduction - not CO2-Compensation09-2010

  • Influencing Variables in the Pressroom Energy IPA in water Cleaning agents and washes Paper09-2010

  • Influencing Variables in the Pressroom with every liter (0.78 kg) of IPA 1.712 kg CO2 are set free, this means: with a consumption of 5,000 liter of IPA per year/press approx. 8.5 to of CO2 are produced

    with every liter (0.8 kg) cleaning agent (e.g. RW 220 063) 2.490 kg CO2 are set free this means: with an avarage consumption of 9,000 liter cleaning agent per year/press approx. 22 to CO2 are produced09-2010

  • 1.) Underlying chemical equation (combustion): CH3-CH-OH-CH3 + 4,5 O2 ===> 3 CO2 (gas) + 4 H2O corresponding molecular weights in g/mol: 60.1 + 4.5 x 32 ===> 3 x 44 + 4 x 18Calculation of the releasable hydrocarbon equivalents during the combustion of Isopropanol (IPA)09-20102.) Result: 1 mol IPA (60.1 g/mol) produces 3 mol CO2 (132 g/mol) 3.) Question: How many liter of CO2 are set free by combustion of 1 liter IPA ? Solution: Density of IPA = 780 g/l (20C), divided by 60.1 g/mol = 12.98 mol/lIn other words: 1 liter IPA = 780 g = 12.98 mol/l.4.) As per mol IPA 3 mol CO2 are set free (see also item 1), the mol/l are converted into g as follows: 12.98 mol/l IPA x 3 = 38.94 mol CO2 x 44g/mol (molecular weight CO2)

    During the combustion of 1 liter (= 780 g) IPA 1712.4 g CO2 are produced5.) Conversion of g CO2 into liter CO2 (molar volume of a gas: 22.4 liter) according to item 4, during the combustion of 12.98 mol/l IPA 38.94 mol CO2 x 22.4 liter are produced

    During the combustion of 1 liter (= 780 g) IPA 873 Liter CO2 are producedInformation: The natural CO2 content in the air is 0.03 Vol.-%, 1000 liter air contain 0.3 liter CO2

  • 1.) Underlying chemical equation (combustion): C15H32 + 15.5 O2 ===> 15 CO2 (gas) + 16 H2O corresponding molecular weights in g/mol: 212 + 15.5 x 32 ===> 15 x 44 + 16 x 18Calculation of the releasable hydrocarbon equivalents during the combustion of Rapid Wash 220 06309-20102.) Result:1 mol RW 220 063 (212 g/mol) produces 15 mol CO2 (660 g/mol) 3.) Question: How many liter of CO2 are set free by combustion of 1 liter RW 220 063? Solution : Density of RW 220 063 = 800 g/l (20C), divided by 212 g/mol = 3.77 mol/l. In other words: 1 liter RW 220 063 = 800 g = 3.77 mol/l.4.) As per mol RW 220 063 15 mol CO2 are set free (see also item 1), the mol/l are converted into g as follows: 3.77 mol/l RW 220 063 x 15 = 56.6 mol CO2 x 44g/mol (molecular weight CO2)

    During the combustion of 1 liter (= 800 g) RW 220 063 2490 g CO2 are produced.5.) Conversion of g CO2 in liter CO2 (molar volumen of a gas: 22.4 liter) according to item 4 during the combustion of 3.77 mol/l RW 220 063 56.6 mol CO2 x 22,4 Liter are produced During the combustion of 1 liter (= 800 g) RW 220 063 1267.9 liter CO2 are produced.Information: The natural CO2 content in the air is 0.03 Vol.-%, 1000 liter air contain 0.3 liter CO2

  • CO2-Savings by IPA Reduction Technical adjustments on the printing press are not required for IPA- reduction or IPA-free printing IPA-free printing will not cause any disadvantages regarding printing technique Fountain solutions for IPA-free printing are compatible with other fountain solutions, which means that PSO can be reached without problems. 09-2010
