the equation by a trial and error process we obtain the outlet temperature value as 623.8 K. Hence it is assumed that the outlet temperature is 623 K itself. Primary Reformer Within the reformer steam reacts with Naphtha and produces Carbon monoxide and Hydrogen. Side reactions also take place producing Carbon dioxide and ( ) C n H m + nH 2 O → nCO + m 2 + n H 2 Methane. The exit gases from the reformer are at a temperature of 1093 K . ∆Hr is 53.376 x 103 kcal/kmol ∆H1 is 10

Did you know that for every cigarette you smoke you can lose eleven minutes off your life? Smoking can not only leave you with long term affects you may not be able to get rid of but it will leave you poor and maybe dead. Mankind first came in touch with tobacco approximately eighteen thousand years ago‚ when migrant Asiatic people first intersected the Bering Strait and extended across the continents today known as the Americas‚ where tobacco is native (Gately ‚2001).

Manures The deficiency of plant nutrients and organic matter in the soil is made up by adding manures and fertilizers to the soil of crop-fields. Both manures and fertilizers are major sources of nutrients of plants‚ so they are used in crop production. Besides water CO2 and sunlight plants required no. of elements for their growth. These elements are known as nutrient. Plants get their elements from the salt of these elements present in the soil. But after repeated cultivation of plants soil become

http://eschooltoday.com/pollution/noise-pollution/sources-of-noise-pollution.html Environmental pollution is one of the biggest problems the world faces today. It is an issue that troubles us economically‚ physically and everyday of our lives. The contamination of the environment is also being linked to some of the diseases that are around currently. Yet‚ most people do not know about this problem. This shows that environmental pollution is becoming an increasingly worse problem that needs to be

Hospitality Law Hospitality law has evolved as a specialty within the legal profession in the last several decades. It is also offered as a course on the undergraduate and graduate levels as well as in some law schools. A typical hospitality law course covers the history of hospitality law‚ the impact of federal and state civil rights laws on the hospitality industry‚ and an extensive discussion of contract law‚ including discussions of remedies for overbooking and a guest’s breach of the contract

Chemical Formula Principles Chemical Formula is a system of chemical notation that was invented in 181 by John Jakob Berzelius. The system is based on the law of definite proportions”‚ states that all samples of a given chemical compound have the same elemental composition. It is also a way of expressing information about the proportions of atoms that constitute a particular chemical compound‚ using a single line of chemical element symbols‚ numbers‚ and sometimes also other symbols‚ such as
