Sulfur in feedstocks are increasing steadily. Consequently, changes in regulations force industrial companies to operate Sulfur Recovery Units more efficiently. An industrial Sulfur Recovery Unit of TUPRAS, Turkey was modelled by Matlab by using simplified kinetics. Proposed model was validated with the industrial data of TUPRAS. The model represents the important species with minute deviation. According to the model proposed, conversion and recovery were found to be 65.24% and 86.88%, respectively; where they were calculated to be 64.91% and 82.72% in design case. Moreover, effects of air temperature were studied in this work. According to the simulation results, up to $13,200/year can be saved by removing preheating. Because carbon content is essential in gas mixture, effects of COS and CS 2 on catalytic part after this modification are found to be negligible in short term. This design change also increases the sulfur production by about 600 kg/day. On the other hand, amount of COS, CS 2 , H 2 S released from Selective Oxidation Reactor would be enhanced from 25 to 31 ppmmol, which increase overall SO 2 emission from incinerator.

The recycled plastics (RHDPE and RLDPE) were exposed to environment conditions for many years. Also the chemical contaminants had effects on the thermo-mechanical and other properties of these wastes. Then a weathering effect data is examined for both Iraqi and Foreign wastes on the thermo-mechanical and chemical properties (Tensile strength, modulus, elongation, impact and permeability).The different mathematical software model were applied to analysis these weathering – properties data in order to estimate which one or several among these properties had more effective by these weathering conditions such as (concentration of contaminant, time, temperature, thickness of specimen, length of spectra, basic property). The results shows that a multi-polynomial model has a best fit for most or several of properties to active weathering variables, also gave a vary residual and deviation than experimental analyzed data for both sources of wastes Iraqi and Foreign RHDPE and RLDPE. Also the results for thermo-mechanical and chemical properties prove that both tensile strength and modulus of elasticity thermo-mechanical properties and permeability / length of spectra chemical property were given a high quality of correction and fitting factor from 93-99 %, with less deviation and residual function was produced. And the results of RHDPE gave a best fit than RLDPE for most of checked analysis properties (thermo-mechanical and chemical properties).

Chemistry is the science concerned with the composition, structure, and properties of matter, as well as the changes it undergoes during chemical reactions. Chemical reactions are processes by which the original substances are changed into new ones by making or breaking of chemical bonds. Each chemical is characterized by a symbol or a formula derived from the scientific name of the element where a specific reaction is described as combination of the formula of the reactants and products. The major aim of the paper is to demonstrate different aspects if chemistry by artworks which makes the concept of chemistry more clear and easy to understand
