1 CHAPTER 1 PROJECT BACKGROUND 1.0 PROJECT BACKGROUND The main objective is to design an economic Acrylonitrile chemical plant with safer ways of processes for a minimum production rate of 100‚ 000 metric tonnes/year. 1.1 INTRODUCTION Recently‚ production of acrylonitrile has been increasing every year in many countries. The rapid growth of the industry is mainly attributed to the availability of oil and gas as feedstock‚ a well-developed infrastructure‚ and a strong base

and these comprise only 20 kinds of amino acids in various combinations. These 20 kinds of amino acids are essential to the body. In addition to being the materials for proteins‚ they are used as an energy source for the body as necessary. Further‚ each amino acid plays an important and unique role in the body. The list below shows the role of each amino acid. | Valine Leucine Isoleucine | All of these 3 amino acids are called branched chain amino acid(BCAAs). They perform the important functions

experiment was observed for three days. The chemicals used were copper sulfate (blue crystals)‚ sodium chloride (salt)‚ and iron. Copper sulfate is a chemical compound which is produced commercially by reacting various copper (II) compounds with sulfuric acid [1]. It generally appears as a bright blue or green crystal [1]. Its chemical formula is CuSo4. Iron is silver-white magnetic metallic and readily rusts in moist air [3]. Its chemical formula is Fe. The chemical reaction was demonstrated by

Citric Acid Names of chemical substance- Chemical formula: C6H8O7. Elements present in citric acid are; carbon‚ hydrogen and oxygen. Bonding- All the elements in citric acid are non-metals. Citric acid has a covalent bond type. History- in the 8th century jabir ibn hayyar a Persian alchemist was credited with the discovery of citric acid. in 1784 the separation of citric acid from citrus fruits occurred when Swedish chemist Carl Wilhelm Scheele separated citric acid from lemon juice.

Science one world essay – Acid Rain Acid rain has been an important global issue for centuries. Although most acid rain is caused by human activities‚ some acid rain occurs naturally. An example of natural acid rain is erupting volcanos‚ they give off smoke containing water vapor‚ carbon dioxide‚ sulphur dioxide and nitrogen compounds. The sulphur dioxide and nitrogen compounds cause small amounts of acid rain near the volcano. Pure water is not an acid‚ but even clean rainwater is slightly acidic

Amino acids are the building blocks of proteins. Amino acids bind together to form polypeptide chains‚ and these polypeptides fold and coil together into specific conformations to form proteins. There are 20 different amino acids‚ each amino acid consisting of four distinct partners. The first is a carboxyl group. A carboxyl group has very weak acids that are able to donate hydrogen ions to biological reactions. The second partner is the amino acid group. Amino acid groups act as the base which‚

1999 Adipic Acid (98/99-3) Currently operating commercial production processes for adipic acid depend on the production or purchase of KA oil (a mixture of cyclohexanone‚ the ketone or K component‚ and cyclohexanol‚ the alcohol or A component)‚ or of pure cyclohexanol‚ and its subsequent oxidation in solution to adipic acid using an excess of strong nitric acid. This report deals with KA oil/cyclohexanol production by various routes‚ followed by the common step of nitric acid oxidation. KA
