Optimization of chicken nail extracts as corrosion inhibitor on mild steel in 2M H2SO4

The inhibiting effects of Chicken Nails Extract (CNE) on Mild Steel corrosion in 2M H2SO4 were investigated in this study. The effect of the concentration of inhibitor (0.5–1.5 g/l), time (5–8 h) and temperature (40-70o c) on Inhibition efficiency were investigated using Response Surface Methodology. The Physiochemical analysis and proximate analysis of the CNE were investigated; the result showed that organic constituents were present which made the Chicken nails extract a good inhibitor. The rate of corrosion increases as time and temperature increase while the Inhibition efficiency was discovered to increase as the inhibitor concentration increases. The optimum conditions obtained were temperature 63.63 C, time 5 h and inhibitor concentration of 0.1 g/l. The optimum Inhibition Efficiency at these optimum conditions was predicted to be 74.04%. The micrographs result of Scanning Electron Micrographs analysis showed that in the presence of the inhibitor, there was a passive layer of a film formed on the surface. This study revealed that Chicken Nails Extract is a potentially good green inhibitor for Mild steel corrosion in 2M H2SO

INVESTIGATIVE STUDY OF THE EFFECTS OF CERTAIN ADDITIVES ON SOME SELECTED REFRACTORY PROPERTIES OF ANT-HILL CLAY FOR FURNACE LINING

The choice of appropriate locally sourced refractory materials for lining of locally produced furnaces has remained a major concern in which numerous efforts has been put in place to enhance the performance of the local contents of furnace lining materials. This study investigates the effects of certain additives such as Pulverized Glass Wastes (PGW) and Bentonite on some selected refractory properties of ant-hill clay. 100% finely-ground ant-hill clay, clean water and proportionate amount of Bentonite and PGW were manually mixed, consolidated and oven-dried at 110 oC for a period of 8 hours at varying additives percentages. Compressive strength, apparent porosity, permeability, filtration rate, thermal conductivity and bulk density were experimentally determined... The results showed that the compressive strength, bulk density and thermal conductivity of Ant-hill clay increased significantly on addition of additives while there was corresponding decrease in the values of the filtration rate, apparent porosity and permeability. These values were enhanced by Bentonite and pulverised glass waste additions to the Ant-hill clay. The test results for the compressive strength, thermal conductivity, filtration rate, apparent porosity, bulk density and permeability of no-additive clay samples are 156.4 N/m2 , 0.0028 W/m2K, 0.0041cm3 /s, 0.0009 %, 6.3 g/cm3 and 0.0012 cm/s, respectively. However, the sample-mix consisting 100% ant-hill clay with 80% PGW and 20% Bentonite produced 333.4 N/m2 , 0.0032 W/m2K, 0.0037 cm3 /s, 0.00018 %, 9.5 g/cm3 and 0.0015 cm/s as optimum values for the compressive strength, thermal conductivity, filtration rate, apparent porosity, bulk density and permeability, respectively. Therefore, 80%PGW/20%Bentonite additives gave the optimum results for the production of refractory clay blocks for furnace linin

EVALUATION OF GROUNDNUT LEAVES EXTRACT AS CORROSION INHIBITOR ON MILD STEEL IN 1M SULPHURIC ACID USING RESPONSE SURFACE METHODOLOGY (RSM)

1M H2SO4 acidic media was investigated in this study. The effect of the concentration of inhibitor (0.2 - 1.0 g/l), time (3 – 5 days) and temperature (40�60 �) on corrosion rate and Inhibition efficiency were investigated using Response Surface Methodology (RSM). The Phytochemical analysis of the GLE was performed; the result showed that organic constituents were present which made the Groundnut Leaves Extract a good inhibitor. Mathematical models were derived for the groundnut leaves extract. The optimum conditions obtained were temperature 49.72 OC, time 5 days and inhibitor concentration of 0.29 g/l while the optimum Inhibition Efficiency at this optimum condition was predicted to be 85.9%. The outcome of the ANOVA test confirmed a confidence level of 95%. Gravimetric experiment was carried out at these optimum conditions to validate the predicted optimum values. The obtained experimental value of 86.3% agreed closely with that obtained from the regression model. The micrographs result of Scanning Electron Micrographs analysis showed that passive layer of film was formed on the surface. This study has revealed that Groundnut Leaves Extract is a good inhibitor for the corrosion of Mild steel in 1M H2SO4 solution.

INHIBITION EFFECT OF ORANGE SEED EXTRACT ON ALUMINIUM CORROSION IN 1M HYDROCHLORIC ACID SOLUTION

Corrosion of metals has become a critical environmental challenge which has gained more attention over the years especially in oil and gas industries. The use of plants or organic extracts as corrosion inhibitor has become imperative as a result of their environmental acceptability, local availability as well as being renewable sources for a wide range of green inhibitors. The use of natural or organic products such as leaves and seed extracts has been widely reported but a few works have been done on the use of orange fruit seed extract as an eco-friendly corrosion inhibitor for Aluminum. Hence, in this study, the inhibiting effect of Orange fruit (Citrus synensis) seed extract on Aluminum corrosion in 1M Hydrochloric (HCL) Acid solution was investigated using weight loss measurement and phytochemical analysis. The study was conducted at a temperature of 30oC with concentration of inhibitor varied from 0-0.3g/l in the acidic medium for 10 days. It was observed that the corrosion rate increases as the concentration of the inhibitor decreases with time. The result showed that at the inhibition concentration of30%, the inhibition efficiency and corrosion rate obtained in HCL solution are 38.37% and 0.012 g/m2 respectively, thereby giving the highest inhibition effect. Thus, it can be concluded that orange seed extract is a good corrosion inhibitor. Keywords: Aluminum, Corrosion, Orange fruit seed, Inhibition, Weight los
