In this study, corrosion behavior of welded and unwelded austenitic stainless steels, SS304, SS310, SS316 were investigated using three different stirring speeds; 100, 200, 350 rpm and were subjected to two different corrosive environments; seawater (3.5% NaCl), and acidic ferric chloride (FeClᴣ). The rate of corrosion was measured using spectrophotometry. The microstructure was examined using optical microscopy. Experimental results indicated that the highest corrosion rate was observed in acidic ferric chloride, 8.56 mg. min -1 .cm -2 for SS304 at 350 rpm speed (high mechanical stress condition), compared to seawater under the same conditions, 7.96×10 -4 mg. min -1 .cm -2 . Welded stainless steel area were highly sensitive to the corrosive environment as a result of the increasing thermal stresses in both the weld zone and the heat affected zone (HAZ). Also, the corrosion rate was found to increase with increasing the stirring speed due to its effect on the mass transfer and mechanical stresses.","PeriodicalId":13949,"journal":{"name":"International Journal of Chemical Engineering and Applications","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81195992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current process uses the dipolar aprotic solvent N-methyl-2-pyrrolidone (NMP) as a synthesis reaction medium. NMP is associated with harmful environmental a health effects. Dimethylsulfoxide (DMSO) and sulfolane are also dipolar aprotic solvents with similar physical properties of NMP but are less harmful. With the substitution of NMP for DMSO or sulfolane in the resin precursor process, total life cycle emissions were reduced by 52% and 61%, respectively. Distillation processes were designed to evaluate the environmental impacts of recovering solvent from the waste. Total life cycle emissions were reduced by 63% when comparing the current operation using NMP with the case of the current operation with solvent recovery. There was no additional significant reduction on life cycle emissions for the cases with solvent recovery for DMSO or sulfolane. Thus, the importance of evaluating all green engineering options through a life cycle assessment is important to fully understand the environmental impact reduction each option possesses.","PeriodicalId":13949,"journal":{"name":"International Journal of Chemical Engineering and Applications","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77648941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lead exposure in humans can have severe neurological and physiological repercussions. The objective of this study is treatment of lead from water by electrocoagulation using iron electrodes applying RSM in an uniquely designed reactor. The evaluation of the main and interaction effects of process variables such as current density, initial lead concentration, pH and Na2SO4 concentration as a supporting electrolyte on the removal efficiency of lead were analyzed applying RSM. The levels of the factors were determined with variance analysis and found to be 10-50 mAcm -2 with the increments of 10 units for current density, 50-250 mgL -1 with the increments of 50 units for initial lead concentration, 3-7 with the increments of 1 units for pH and 0.01-0.09 molL -1 with the increments of 0.02 units for Na2SO4 concentration. As a result of study, it was found that current density has a linear effect while current density and initial pH have quadratic effects on the removal efficiency. Lead removal efficiency reach a maximum value of 98.76% when the current density was 40 mA/cm 2 and initial pH was 4.7.","PeriodicalId":13949,"journal":{"name":"International Journal of Chemical Engineering and Applications","volume":"25 1","pages":"109-111"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85263886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
