WebThe naphtha is a mixture of many different hydrocarbon compounds. It has an initial boiling point(IBP) of about 35 °C and a final boiling point (FBP) of about 200 °C, and it contains paraffins, naphthenes(cyclic paraffins) and aromatic hydrocarbonsranging from those containing 4 carbonatomsto those containing about 10 or 11 carbon atoms. Ammonia production depends on plentiful supplies of energy, predominantly natural gas. Sustainable production is possible by using non-polluting methane pyrolysis or generating hydrogen by water electrolysis with renewable energy sources. Thyssenkrupp Uhde Chlorine Engineers expanded its annual production capacity for alkaline water electrolysis to 1 gigawatt of electrolyzer capacity fo…
WebMinimum area required for manufacturing naphthalene balls is 500 square feet. The plant capacity can be 500 kg per day and the cost of plant and machinery can be around Rs 13 lakh and working capital will cost you around Rs 10 lakh. Thus, the total capital required is Rs 40 lakh and the expected return is 41%.
A naphthalene molecule can be viewed as the fusion of a pair of benzene rings. (In organic chemistry, rings are fused if they share two or more atoms.) As such, naphthalene is classified as a benzenoid polycyclic aromatic hydrocarbon (PAH).
