Stubble burning


Public sector oil marketing companies _ IndianOil, Hindustan Petroleum and Bharat Petroleum _ will seek expression of interest from potential entrepreneurs to set up compressed bio-gas production plants and make it available in the market for use as auto fuel.

This move has the potential to boost the availability of affordable transport fuel, for better use of agricultural residue, cattle dung and municipal solid waste, as well as to provide an additional revenue source to farmers, an official statement said.

The Minister for Petroleum and Natural Gas, Dharmendra Pradhan, will launch the Sustainable Alternative Towards Affordable Transportation (SATAT) initiative on the second last day of the ongoing Swachhta Hi Seva fortnight

What is torrefaction?
It is a thermal process used to produce high-grade solid biofuels from various streams of woody biomass or agro residues.
The end product is a stable, homogeneous, high quality solid biofuel with far greater energy density and calorific value than the original feedstock, providing significant benefits in logistics, handling and storage, as well as opening up a wide range of potential uses.
How it works?
  1. Biomass torrefaction involves heating the biomass to temperatures between 250 and 300 degrees Celsius in a low-oxygen atmosphere.
  2. When biomass is heated at such temperatures, the moisture evaporates and various low-calorific components (volatiles) contained in the biomass are driven out.
  3. During this process the hemi-cellulose in the biomass decomposes, which transforms the biomass from a fibrous low quality fuel into a product with excellent fuel characteristics.

evaporation

what causes water to evaporate every fluid (pure) has a definite vapor pressure at a fixed temperature , now if any how the partial presuure of the fluiid is less then the the vapor pressure of the fluid then the fluid starts evaporating to attain the partial pressure equal to the  vapor pressure of the fluid, and then the equllibrium is reached and evaporation stops.                              basically at the top of the fluid there is a random motion of the fluid molecule due to the difference between the adhasive and cohesive forces, some molecule say 'n' goes into the vapur phase and some strikes back say m such that n>m then after the above explained condition is achived then the constraint m=n. conclusion whenever there is the fluid in liquid state is  present then in that system partial pressure is exactly to the va...
