LPG - Liquefied Petroleum Gas<\/h2>\n\t\t\t\t\t

LPG is a mixture of liquefied hydrocarbon gases. It consists primarily of propane (C\u2083H\u2088) and butane (C\u2084H\u2081\u2080), in variable proportions. Additionally, itmay contain isobutane and n-butane. The mixture is derived from petroleum refining. At ambient temperature and pressure, LPG exists as a gas.However, under moderate pressure it liquefies, enabling efficient storage and transport.<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

Propane (Technical Grade)<\/h2>\n\t\t\t\t\t

Technical propane contains approximately 95% (v\/v) propane (C\u2083H\u2088). The remaining 5% (v\/v) is n-butane (n-C\u2084H\u2081\u2080). In addition, trace quantities ofother hydrocarbons may be present. All composition data are specified in the supplier\u2019s quality documentation. As a result of its high propanecontent, technical propane is the primary fuel used in SNG production and LPG enrichment systems.<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

bioLPG - Renewable Liquefied Petroleum Gas<\/h2>\n\t\t\t\t\t

bioLPG is chemically identical to conventional LPG in composition and properties. However, it is produced from renewable biomass sources.These sources include vegetable oils, animal fats, glycerol, sugars, and organic waste streams. Furthermore, bioLPG is a direct drop-inreplacement for fossil LPG. Therefore, it can be used in all LPG applications - including SNG production and backup gas systems - withoutsystem modifications. As a result, it significantly reduces lifecycle CO\u2082 emissions.<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

SNG - Synthetic Natural Gas<\/h2>\n\t\t\t\t\t

SNG is produced on-site by blending LPG with compressed air. The mixing ratio is precisely controlled in a gas mixer. Specifically, the ratio iscalibrated to achieve a Wobbe Index equivalent to natural gas. The key engineering principle is: NG = SNG (LPG + AIR). As a result, SNG canreplace natural gas in industrial burners without burner modification or reconfiguration. Moreover, the switchover is seamless and does notinterrupt production.<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

bioSNG - Bio Synthetic Natural Gas<\/h2>\n\t\t\t\t\t

bioSNG is produced from biopropane (bioLPG) and air. It is the renewable equivalent of conventional SNG. Therefore, it delivers the samecombustion performance as natural gas. In addition, bioSNG enables progressive decarbonisation of industrial gas supply. Specifically, it replacesfossil LPG with a renewable fuel - without requiring burner replacement or process reconfiguration.<\/p>\n\t\t\n<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

Gross Calorific Value (GCV) - Heat of Combustion<\/h2>\n\t\t\t\t\t

The Gross Calorific Value (GCV) is the heat released by complete combustion of a specified gas quantity. The combustion occurs at constantpressure. All products are returned to the initial temperature. Water condenses to liquid state. Furthermore, GCV is the primary parameter forenergy billing and gas quality certification. It is expressed in MJ\/Nm\u00b3 at standard reference conditions (0\u00b0C \/ 101.325 kPa).<\/p>\n\t\t\t\t\t

Source: EN ISO 6976:2016 - Natural gas - Calculation of calorific values, density, relative density and Wobbe indices from composition.<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

Superior Wobbe Index (Ws) - Upper Wobbe Index<\/h2>\n\t\t\t\t\t

The Superior Wobbe Index (Ws) is the gross calorific value per unit volume. It is divided by the square root of the relative density. Both values aremeasured at the same reference conditions. In particular, the Wobbe Index is the fundamental parameter for combustion interchangeability. Twogases with the same Wobbe Index produce the same heat output through the same orifice at the same pressure. Therefore, it is the key parameterin gas mixing system design.<\/p>\n\t\t\t\t\t

Typical values: Natural Gas (H-gas): 48\u201352 MJ\/Nm\u00b3 | SNG (LPG+AIR, 60% LPG): \u2248 52 MJ\/Nm\u00b3.<\/p>\n\t\t\t\t\t

\n \t\t\t

Reference Gas (Base Gas)<\/h2>\n\t\t\t\t\t

The reference gas is the primary fuel of the process gas supply. All mixing system parameters are referenced to it. Specifically, the Wobbe Index(Ws) of the reference gas defines the target values for the mixed gas output. Furthermore, the reference gas determines the selection and controlsettings of the mixing system. As a result, the blended output delivered to end-use appliances is always calibrated to match the reference gasquality.<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

Corrective Gas<\/h2>\n\t\t\t\t\t

The corrective gas is dosed into the reference gas within the mixing system. Its purpose is to condition and stabilise fuel parameters at the outlet.Specifically, it regulates gross calorific value (Hs), Wobbe Index (Ws), and methane number. Furthermore, the corrective gas may be enriching ordiluting. For example, propane\/LPG\/bioLPG increases calorific value. In contrast, air or nitrogen reduces it. Therefore, the choice of corrective gasdepends on the target gas quality specification.<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

Gas Mixer<\/h2>\n\t\t\t\t\t

A gas mixer combines two or more gas streams into a homogeneous mixture. It provides controlled dosing of all components. Additionally, itensures uniform concentration distribution across the flow cross-section. Moreover, the mixer maintains stability of mixture parameters over time.These include gross calorific value and Wobbe Index. Furthermore, all GasGenix gas mixers comply with ATEX and PED requirements for use inpotentially explosive atmospheres.<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

Static Mixer<\/h2>\n\t\t\t\t\t

A static mixer has no moving parts. Mixing is achieved solely through the flow geometry. Specifically, baffles and mixing inserts force repeatedstream separation and recombination. As a result, turbulence and dispersion increase significantly. Therefore, a static mixer achieves uniformconcentration distribution across the flow cross-section. Additionally, it minimises fluctuations in mixture parameters at the outlet. However, thedesign must maintain an acceptable pressure drop.<\/p>\n\t\t\n<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

Normal Conditions (Nm\u00b3)<\/h2>\n\t\t\t\t\t

Normal conditions are the standard reference conditions used in the gas industry. Gas volume and low are expressed as Nm\u00b3. Energy quantitiesare expressed as MJ\/Nm\u00b3. Specifically, the reference conditions are: absolute pressure 101.325 kPa and temperature 273.15 K (0\u00b0C). Therefore, allGasGenix system flow data are expressed in Nm\u00b3\/h at these standard conditions.<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

Combustion Reference Conditions<\/h2>\n\t\t\t\t\t

Combustion reference conditions define the temperature and pressure at which fuel is assumed to be burned. In Poland, these conditions are 25\u00b0Cand 101.325 kPa. Furthermore, these values are mandatory for correct energy billing and gas quality certification.<\/p>\n\t\t\t\t\t

\n \t\t\t

Working (Operating) Conditions<\/h2>\n\t\t\t\t\t

Working conditions describe the actual state of gas at a measurement point. They are defined by at least pressure (absolute) and temperature.Additionally, gas composition and compressibility factor may be required. As a result, conversion between working conditions and normalconditions requires PTZ calculation.<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

PTZ Conversion (Pressure-Temperature-Compressibility)<\/h2>\n\t\t\t\t\t

PTZ conversion calculates gas volume as a function of pressure, temperature, and compressibility factor. Therefore, it converts measurementsfrom working conditions to Nm\u00b3. Moreover, PTZ conversion is essential for accurate energy metering and billing in gas mixing systems.<\/p>\n\t\t\t\t\t

Backup Gas System<\/h2>\n\t\t\t\t\t

A backup gas system maintains gas supply continuity during NG network interruptions. GasGenix backup systems use SNG (propane-air or LPG-air) mixing technology. As a result, they ensure Wobbe Index compatibility with the reference gas and seamless process switchover.<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

Biomethane Enrichment System<\/h2>\n\t\t\t\t\t

A biomethane enrichment system conditions raw biomethane by injecting propane or LPG. This increases calorific value and Wobbe Index tonatural gas grid levels. Furthermore, GasGenix systems include precision flow control and real-time Wobbe Index monitoring. All components areATEX-compliant and designed to EN 16723:2017.<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

CO\u2082 Vaporization System<\/h2>\n\t\t\t\t\t

A CO\u2082 vaporization system converts liquid carbon dioxide into gas for industrial applications. GasGenix systems use water bath vaporizers.Additionally, they include an integrated gas-fired boiler heating circuit, remote monitoring, and pressure safety systems. Specifically, the safetysystem prevents dry ice formation below the CO\u2082 triple point (5.18 bar \/ \u221278.5\u00b0C). Therefore, the system operates safely even at ambienttemperatures as low as \u221220\u00b0C.<\/p>\n\t\t\n<\/div>\n

Gas Backup System \/ SNG (LPG + Air) Blending System<\/h2>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Process principle:<\/strong> NG = SNG (LPG + AIR) – Wobbe Index (MJ\/Nm\u00b3)This system produces SNG on-site from LPG and compressed air. The blending ratio is precisely controlled to match the Wobbe Index of naturalgas. As a result, the SNG output is fully combustion-interchangeable with NG. Therefore, no burner modification is required during switchover.<\/p>

Key technical parameters (SNG Blender):<\/strong><\/p>

  • Output capacity: 100 to 10,000 Nm\u00b3\/h (3,8\u2013380 MMBTU\/h)<\/li>

    \n \t\t\t

    Methane Number Stabilization System (Syngas + CH\u2084)<\/h2>\n\t\t\t\t
    \n\t\t\t\t\t\t\t\t\t

    Process principle:<\/strong> Syngas + NG (or Biomethane) = Stable Methane Number (MN).
    The methane number (MN) quantifies knock resistance of gaseous fuels in gas engines. It is analogous to the octane number for liquid fuels. Pure
    methane has MN = 100; hydrogen has MN = 0. Furthermore, a low or unstable MN causes engine knock, increased wear, and unplanned
    shutdowns.<\/p>

    Real-world MN values:<\/strong><\/p>

    • Pyrolysis gas A: MN = 35 => CH\u2084 9.69%, H\u2082 60.42%, CO 17.8%<\/li>
    • Pyrolysis gas B: MN = 47 => CH\u2084 13.38%, H\u2082 36.2%, CO 23.66%<\/li>
    • Syngas: MN = 23 => CH\u2084 18.95%, C\u2082H\u2086 13.52%, C\u2083H\u2088 21.18%<\/li>
    • Target after NG stabilization: MN 40\u201350 – safe range for gas engines<\/li><\/ul>

      \u00a0<\/p>

      Applications:<\/strong> Industrial CHP plants, biomass gasification, waste-to-energy, pyrolysis gas utilisation.<\/em><\/p>

      Therefore, the GasGenix stabilization system injects NG or biomethane as a corrective stream. The control system adjusts the blending ratio in
      real time. As a result, the MN remains stable within the engine\u2019s operating range.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\n<\/div>\n

      Heating Value Stabilization \/ Enrichment System (NG + LPG)<\/h2>\n\t\t\t\t
      \n\t\t\t\t\t\t\t\t\t

      Process principle:<\/strong> NG + LPG \u2192 Heating Value \u2191 (MJ\/Nm\u00b3).<\/p>

      This system doses LPG (propane or propane\/butane) into a natural gas stream. The purpose is to increase or stabilise the gross calorific value
      (GCV) and Wobbe Index. As a result, the enriched gas meets the quality requirements of industrial end-use appliances.<\/p>

      Verified calculation example:<\/strong><\/p>

      • Reference gas (NG Lw): 35.87 MJ\/Nm\u00b3 | Blended with 9.48% propane (100.53 MJ\/Nm\u00b3)<\/li>
      • Target mixture: 42.00 MJ\/Nm\u00b3 | Wobbe Index: 50.58 MJ\/Nm\u00b3 (within H-gas spec)<\/li>
      • Total flow: 3,314 Nm\u00b3\/h (3,000 Nm\u00b3\/h NG + 314 Nm\u00b3\/h LPG)<\/li><\/ul>

        \u00a0<\/p>

        Applications:<\/strong> Gas distribution operators, glass and metallurgical industry, biomethane injection, peakshaving installations.<\/em><\/p>

        Furthermore, this system is widely used for biomethane grid injection, where raw biomethane GCV must be uplifted to H-gas network specification.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\n<\/div>\n

        \n \t\t\t

        Energy Flow Control Gas Blending System (SNG + NG)<\/h2>\n\t\t\t\t
        \n\t\t\t\t\t\t\t\t\t

        Process principle:<\/strong> NG (limited) + SNG = defined energy output (kWh).<\/p>

        This system supplements a capacity-limited NG connection with SNG. The purpose is to achieve a defined energy flow rate (kWh\/h) at the process
        inlet. Therefore, it is used where the NG network connection is insufficient for peak demand.<\/p>

        Verified calculation example:<\/strong><\/p>

        • NG (Group E, 41 MJ\/Nm\u00b3): 1,000 Nm\u00b3\/h available \u2192 supplemented with 797.79 Nm\u00b3\/h SNG<\/li>
        • Target energy output: 25,000 kWh | Wobbe Index of mixture: 53.22 MJ\/Nm\u00b3<\/li>
        • Blending ratio: 55.62% NG + 44.38% SNG.<\/li><\/ul>

          \u00a0<\/p>

          Applications:<\/strong> Industrial heating, glass furnaces, drying lines, food processing, and any facility with insufficient NG connection capacity.<\/em><\/p>

          Furthermore, the system enables precise energy accounting and OPEX optimisation. As a result, clients achieve a lower blended gas cost
          compared to 100% SNG supply.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\n<\/div>\n

            • bioLPG: 9.20 kgCO\u2082\/GJ – identical energy content to LPG, renewable origin.<\/li>
            • Verified result – BioSNG 34.31% + NG 65.69%: CO\u2082 reduction 30.00% vs 100% NG.<\/li><\/ul>

              CO\u2082 emission reference data (KOBIZE):<\/strong><\/p>

              1. Configuration A – Biomethane + SNG: Biomethane (from biogas upgrading) is injected into the SNG stream. This reduces the fossil carbon
                fraction of the backup gas supply.<\/li>
              2. Configuration B – BioPropane + AIR = BioSNG + NG: Renewable biopropane is blended with air to produce BioSNG. It is then injected into the
                NG stream. Therefore, this configuration enables renewable backup supply without a biomethane grid connection.<\/li><\/ol>

                Source: EU RED III 2023\/2413; KOBIZE.<\/em><\/p>

                This system injects renewable gaseous fuels into the fossil gas stream. Specifically, it blends biomethane or bioSNG into natural gas or SNG. As a
                result, the carbon intensity of the fuel decreases proportionally to the renewable fuel blending ratio.<\/p>
