Carbon Disulfide Adsorption Plant

On the opening area Carbon Disulfide (CS2) is on the gas form, because CS2 have boiling point at about 46oC at atmospheric condition and CS2 is a flammable. On the plant that use CS2 as raw chemicals material and then release CS2 gas should have waste gas treatment to catch this release gas before the flue gas been through away to the environment. There are several type of CS2 catch process that is used on waste gas treatment plant, and some of them use CS2 adsorption plant.

CS2 adsorption plant recovers CS2 from the lean gas using vapor phase adsorption onto activated carbon. The CS2 laden lean gas stream is passing through the activated carbon (AC) bed in the adsorber where CS2 gas molecules are adsorbed onto the large surface of AC.

The adsorption ceases at the equilibrium point at which the AC can not take up any more of CS2. CS2 recovery starts by desorption of CS2 gas molecules from the AC and followed by the condensation of CS2. Thermal energy of steam is employed to desorbs CS2 from the AC. The CS2-steam mixture is subsequently cooled and condensed. CS2 is collected as pure product.

Basic Chemistry

Chemistry is the physical science that deals with composition, structure and properties of substance and also the transformation that these substance that undergoes. Because the study of chemistry encompasses the entire material universe, it is central to the understanding of other science. Basic chemistry involve in all aspect on live, the incident in around you actually is the basic chemistry process such as the changes of compost from fresh there is any chemical reaction involved there even the process itself is help by microorganism. A basic chemistry theory has been formulated as the result of centuries of observation and measurement of the various elements and compounds. According to this theory, matter is composed of minute particles called atoms. The more than 100 different kinds of atoms that are known are called chemical elements. Atoms of the same elements or of different elements can combine together to form molecules and compounds. The atom are held together by forces,...

Gas Reaction and Solid Reaction

Gas Liquid Reactions When gaseous reactants are absorbed by a liquid, and a chemical reaction takes place , both chemical reaction and mass transfer may control the overall reaction rate. For analysis of this type of system should be consulted. Books by Astarita, Danckwerts, and Sherwood, Pigford, and Wilke should also be helpful. Treatments similar to these references are likewise applicable to the liquid liquid system if chemical reaction is involved in only one of two partially miscible phases and the overall rate is governed by both mass transfer and chemical reaction. Solid State Reactions The solid state reactions refer to decomposition and interaction of solids, and are generally more complex than those of other systems discussed preciously. There have been few systematic analyses of chemical reactions in the solid state. Fairly comprehensive treatments of such reactions are presented in two recent publications by Bamford and Tipper and Schmalzried respectively. Genera...

Viscose Fiber Production Process

Viscose fiber is a base material for textile industry. The first production of this kind product is in Indian than spread over the Europe and United States also in South Asia Country like in Indonesia. Viscose fiber is produced to anticipate the shortage of natural yarn for raw material to produce yarn in textile industries, beside synthetic yarn as replace natural cotton to produce fabric. This one is a simple drawing of viscose fiber production process . Viscose fiber is used to substitute the using of cotton as raw material for textile industry. Beside of cotton availability will not enough to supply market demand in the future, also cotton just available on harvesting season. If people just depend on cotton to produce textile then people will shortage of raw material to produce textile. Using viscose fiber to fulfill of textile industry will not any shortage raw material, beside the price is lower than cotton, viscose fiber also have better quality compare with synthetic fiber fo...
