Pure Steam
This steam is used for injectable drug production. Pure steam is regularly used when absolute sterility is necessary to guarantee process repeatability.
Steam generated is used in the following processes:
Atomization: Steam made in boilers is used for the purpose of atomizing the liquids. This is important for applications like film coating, preparation of fine (usually nano-size) powders etc.
Humidification: Aqueous tablet coatings demand extreme control of humidity so that the coating does not dry too fast or too slow. Pharmaceutical printing processes as well require temperature control to prevent water-based inks from drying during processing.
Drying: This is commonly the last stage in the manufacturing process. This is done in order to remove any moisture from the tablets, vaccines as it may lead to corrosion and decrease the product or drug stability. It is also done keep properties like flowability, compressibility intact and for operations like filtration and crystallization.
Sterilization: This is done to ensure that the medication is free of contamination. Steam is released via an LPG powered autoclave or high-speed pre vacuum sterilizer. The medication is exposed to direct steam at a required pressure and temperature for a specific duration.
Local Impact Around 4 lakh Indian citizens have deceased due to the use of burning of fuels that emit pollutants such as benzene, sulphur dioxide, carbon monoxide, and metals including copper and lead. Also, pollution from such fuels contribute to 12% of still births in the country. In order to eradicate the use of harmful gases, the Government of India launched the Pradhan Mantri Ujjwala Yojana scheme with the aim to promote LPG. The scheme encouraged several to give up their LPG subsidy making LPG an economic source for all
