HOSPITALS:

Hospitals are open 24*7, with thousands of patients, visitors and employees occupying the space. This rises the need for sophisticated heating, ventilation, and air conditioning (HVAC) systems for temperature control and air flow. Other activities such as laundry, medical and lab equipment use, sterilization, computer and server use, food service, and refrigeration utilize large amounts of energy.
Due to all of the above, LPG and natural gas are essential fuels to hospitals globally. Below mentioned are few applications of how they are used in hospitals.

  1. Bio – Medical Waste
    Hospitals generate harmful bio-medical waste which needs to be safely disposed via incineration. Incinerators use LPG in order to achieve temperature high enough for complete combustion of the waste without any harmful emissions.
  2. Laundry
    Several hospitals make use of gas fired boilers. Steam generated from these boilers is used to heat the water for washing, run dyers and heat ironing equipment.
  3. Cooking
    Hospitals in certain parts of the developing world have introduced LPG kitchen schemes which allow attendants of patients to use LPG stoves for cooking at a minimal charge. This enables them to reduce their expenses and free themselves from hazards of cooking in the open with inefficient fuels.
    Jehangir Hospital trusts LPG to be the safest form off fuel for their hospital and have thus, installed LPG pipelines for their kitchen.

PHARMACEUTICALS:

The pharmaceuticals industry requires a lot of direct and indirect heating. This is provided via clean steam and pure steam generated in gas fired boilers. They are a critical component to any pharmaceutical plant as they require high temperature control demands.

  1. Clean Steam
    It does not contain any dissolved materials and is required in facilities producing sterile products.
  2. 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:

  1. 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.
  2. 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.
  3. 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.
  4. 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.
