Analisis Besi (Fe) yang Terkandung dalam Larutan Benfield Menggunakan Spektrofotometer Uv-Vis

Corrosion is one of the important problems faced by advanced industrial groups. Some of the equipment that often experiences corrosion is the absorber and stripper equipment used to separate CO2 gas. CO2 gas is an impurity gas whose presence in natural gas can affect the value of methane gas (CH4) so that it will reduce the combustion value of a gas fuel, therefore the gas must first be purified from the presence of CO2. The absorption process is a process that can remove CO2 content in natural gas. Benfield solution is a form of system in the form of a solution that is used to absorb and separate gas impurities such as H2S gas and CO2 gas. The aim of this research is to determine the iron content in the Benfield solution. One tool used to check iron content is a visible light spectrophotometer (UV-Vis). From the results of the analysis of the iron content in the Benfield solution, it can be concluded that the iron (Fe) content produced is 202-E (15.17 and 6.19 ppm), 1102-E (37.94 and 44.70 ppm) and for SL (37.77 ppm and 37.47 ppm). This shows that there is no corrosion on the equipment which does not exceed the set standard value, namely 50 ppm. So the vanadium contained in the Benfield solution as an anti-corrosion coating works well.
