Kjeldahl method of nitrogen analysis is the worldwide standard for calculating the protein content in a variety of materials from human and animal food‚ fertilizer‚ waste water and fossil fuels. This method is an analytical method to quantitatively determine the nitrogen in certain organic compounds. A food is digested with strong acid so that it releases nitrogen which can be determined by a suitable titration technique. The amount of protein present is then calculated from the nitrogen concentration

Ammonia is an important chemical for fertilizer industry. About 85% of ammonia production is used for nitrogen fertilizers [1]. Urea alone consumes 40% of the total ammonia production. Other fertilizers that are made from ammonia are ammonium nitrate‚ ammonium sulfate and ammonium phosphate. Non-fertilizer applications include the production of aminies‚ nitriles (e.g. acrylonitile) and organic nitrogen compounds. Saudi Arabia has ample reserves of natural gas. It is proposed to manufacture ammonia

)4) = 1.254; Answers to Questions: 1. Capacity to gain or absorb heat energy is defined as heat capacity of gas. 2. Rüchard’s experiment is about measurment of Y value with the help of the pressure which is exerted by certain gases such as nitrogen or carbon dioxide. When system is opened the gas is allowed to flow inside the system and it pushes oscillator upwards. The small hole at the top of system decreases inside pressure and oscillator comes back. And it goes on like this‚ up and down

The method that used in this lab is the nitrogen gas (Reslab digital gas permeameter). In addition‚ the gas flow expressed by the Darcy’s equation which relates volumetric flow and pressure drop with the properties of the fluid and media. The permeability is the production capacity of hydrocarbon

• The total carbon component completely gets oxidized to produce CO2 and no fuel is produced. • Some form of nitrogen is also lost in the form of ammonia. • Biogas is produced from wet biomass with about 90-95% water content by the action of anaerobic bacteria. • The conversion process is known as anaerobic fermentation (or biodigestion). • Nutrients such as soluble nitrogen compounds remain available in solution and provide excellent fertilizer and humus. • The energy available from

the coffee residues believing that there is nothing more to be obtained from using these residues. However‚ with a little research you will soon get to find out that coffee residues can be used as fertilizer. Coffee residues contain low levels of nitrogen as well as small amounts of calcium and magnesium‚ and traces of salt. Although fresh grains of coffee have high acidic levels‚ once they have been brewed the acidic levels become low‚ which makes them a good additive to alkaline soils. This study

travels through the food chains and returned to sediment. When the main reservoir of the nutrient is the atmosphere it is considered a gaseous cycle. The carbon and nitrogen cycles are gaseous cycles. Carbon enters the environment during photosynthesis and is returned through cellular respiration. Nitrogen enters the cycle by nitrogen fixation and results in ammonia and nitrates that are carried to the Earth by precipitation. Once they entered into

the mass of this compound. Plant foods contain three essential nutrients that are not readily available from soils. These are soluble compounds of nitrogen‚ phosphorus‚ and potassium. A typical label on a plant food will have a set of numbers such as 15-30-15. These numbers mean that the plant food is guaranteed to contain at least 15% nitrogen‚ 30% phosphorus (expressed as P2O5) and 15 % potassium (expressed as K2O). The remaining of the product is fillers‚ dyes and other anions and cations to
