Flammable group of gases (Hydrocarbons)


They occur in practically every segment of life. The most famous representative is natural gas (methane, CH4), and the combinations of carbon and hydrogen molecules are practically unlimited. We use them as energy sources in all endothermic processes and in almost all industries (chemical, petroleum, pharmaceutical, petrochemical). The biggest problem is their flammability and explosiveness, and for the most part, toxicity. They are one of the biggest risks in all industries. Flammability directly depends on their concentration in the air mixture and ranges between LEL - Lower Explosive Limit and UEL - Upper Explosive Limit. At concentrations of 4.4% to 17% by volume of methane in the air, the spark causes an explosion, so 4.4% v / v CH4 = 100% LEL.

The standard limits of alarm settings within the EU are Low = 10% LEL, High = 20% LEL
