I will have the pleasure of speaking during the thematic session “Biomethane in Practice.”
I will present a proven solution: "Technology for Enriching Biomethane with Propane – A Reliable Way to Maintain Fuel Calorific Value."
This is not just a technology – it's a concrete response to the quality and energy challenges faced by biomethane operators and end users. Biomethane getting closer – are we ready? See you in Poznań!

When we use SNG (Propane-AIR)?

most frequently asked questions

1

What is SNG, and where is it applied?

Created with Pixso.
Synthetic Natural Gas (SNG) is a gas obtained by blending air with any gas or gas mixture, having a calorific value equal to the calorific value of methane. Information on blending Liquefied Petroleum Gas (LPG) with air is presented on our website. SNG is used to replace natural gas in industrial enterprises, gas power plants, and is applied for the gasification of settlements (cities, districts, villages). SNG can also be referred to as gas containing methane (CH4), obtained through coal gasification. Bio-SNG can be called gas containing methane, obtained through biomass gasification or biogas recovered from landfills, but bio-SNG can also be referred to as gas obtained in the process of blending bio-LPG with air.

What is the cost of SNG system and how to choose the equipment?

Created with Pixso.
To select the appropriate equipment and estimate costs, four main parameters need to be considered: 1. Maximum flow of SNG or natural gas per hour in normal cubic meters (Q = ? Nm3/h or MMBTU/h). 2. Gas pressure at the connection point (P = ? from 0.035 to 10 bar or from 0.5 to 145 psi). 3. Required calorific value of the gas (heat of combustion), for example, for natural gas 8,900 kcal/m3 (1000 BTU/Cu.Ft.), but some facilities in the European Union may use nitrogen-enriched gas, and its calorific value may be 5,260 kcal/m3 (22.0 Mj/m3). 4. Propane and butane ratios in LPG gas, for example, 60% propane and 40% butane. 5. The installation costs of SNG systems are several times lower than the installation costs of LNG for industrial enterprises. Please leave us your request on our website with the above-mentioned parameters, and we will send you an offer for connecting the SNG system.

What is SNG blender (LPG Air Blender)?

Created with Pixso.
SNG-blender, is a device where LPG (liquefied petroleum gas) and air are automatically mixed under high pressure in the required ratio, producing SNG gas (synthetic natural gas) with properties similar to natural gas (NG). The SNG-blender is characterized by its precision, automated gas mixing process, and a broad range of adjustments for calorific value and pressure.

(BioLPG) BioPropan, bioDME - what is it? Can BioLPG be used for transportation?

Created with Pixso.
BioLPG, also known as BioPropan, is a type of gaseous fuel that is identical in composition and chemical properties to traditional liquefied petroleum gas (LPG) but is produced from organic materials or waste. The BioLPG production process may involve processing various organic raw materials such as sewage sludge, agricultural residues, sawmill waste, and even bioethanol or the synthesis of renewable hydrogen and carbon dioxide. Currently, BioLPG finds practical application in gas supply systems in the United Kingdom. One of the interesting technologies is the production of DME, which stands for dimethyl ether, a gas similar to propane. DME can serve as both a finished product and an intermediate raw material for the production of biopropane. Its main source of production is the dehydration of methanol. Various raw materials are used for production, including biomass, waste, wood, agricultural products, as well as fossil fuels such as gas and coal. DME can be blended with LPG in proportions of 20% for household purposes (heating and cooking) and 25% - 30% for transportation purposes.
