The “Standard for Methanol Fuel Used in the Curing of Tobacco Leaves and Special Crops” (enterprise standard) developed by Xiehua Chemical has passed the expert review conducted by the Yunnan Standardization Association. Author/Source: Xiehua Chemical; Date: November 15, 2021; Page views: 24. After three years of efforts in tobacco leaf curing trials, Xiehua Chemical’s project on the promotion and application of methanol as an energy source has achieved significant breakthroughs with consistent results, thereby gaining recognition from the tobacco industry. To continuously advance this work and promote its industrial development, there is an urgent need to establish standard systems for methanol fuel, distribution systems, operational safety, and other related areas. The company established a standardization drafting team, and through the continuous efforts of its members, the methanol fuel standards are now ready for review. On November 9, 2021, the “Standard for Methanol Fuel Used in the Roasting of Tobacco Leaves and Specialty Crops” (enterprise standard) was reviewed by the Yunnan Standardization Association in Kunming and received approval from the reviewing experts. At present, the use of methanol fuel is closely integrated with agricultural ecology. Taking advantage of the fact that methanol combustion produces CO2 and water, this fuel is utilized in the field of eco-agriculture, where it plays an irreplaceable role in tasks such as drying tobacco leaves, drying specialty agricultural products, and providing heating and fertilization for flowers grown in greenhouses. When used for drying tobacco leaves, the CO2 produced helps to prevent the breakdown of lutein, accelerates the yellowing process of the tobacco leaves, enhances the activity of amylase, and thus ensures and improves both the external and internal quality of the tobacco leaves ； During the drying process of specialty crops such as peppers, Chinese prickly ash, and cultivated mushrooms, using methanol as fuel causes the released CO2 to enhance both the quality and freshness of the fruits and vegetables during drying ； The combustion of methanol produces CO2, which enters the flower greenhouses; this not only helps to insulate the greenhouses but also supplies carbon dioxide to enhance the photosynthesis of plants such as flowers. The technical requirements set forth in these newly established standards for methanol fuel are stringent; technical indicators such as the methanol mass fraction and water mass fraction are all significantly higher than those specified in the **industrial methanol standards. In addition to meeting the **standard technical requirements, additional parameters for heavy metals have been included: total cadmium, total mercury, total arsenic, total lead, total chromium, total thallium, as well as inorganic chlorine and sulfur. Establish standards for methanol specifically used in the drying of tobacco leaves and specialty crops. This will be of great significance in regulating the market for methanol fuel applications and preventing the adulteration of methanol with other substances, which could disrupt the market.
