xiv, 63 p. : ill. (some col.) ; 30 cm. + 1 CD ROM Scale formation often occurs causing an expensive production problems and usually lowering the oil production rates. Sulphate minerals are amongst the most common scale components in oilfield production wells and surface facilities. Mechanical techniques or chemical treatments are traditionally used to cut through the scale blockage. Water jets are example of mechanicals technique meanwhile HCl and EDTA usually use for the chemical techniques. Thus, the current study was conducted to investigate the solubilities one of the sulphate mineral namely Iron (II) sulphate (FeSO4) when react with solvent of Glutamic acid, N,N-diacetic acid, tetrasodium or also known as GLDA. It has a pH of 4.11 and is heavier than water as its density is 1.2710 g/cm3 and can be used as alternative to nitrilotriacetic acid (NTA) and ethylene diamine tetraacetic acid (EDTA). It has an exceptional high solubility over a wide pH range and is based on a natural and sustainable source which it is contain 86% of renewable raw and non-fossil materials. In this study, it was found that FeSO4 scale is completely soluble when mix with the GLDA solvent. From the observation, mass ratio of GLDA: FeSO4 is 5:2. Based on FTIR and NMR spectrum, it showed that physical interaction occurred between GLDA and FeSO4. Results obtained from the experiment show that is suitable for removing a scaling basically on its physical properties and characterization. specialized Wan Muhamad Syafiq Wan Ismail Faculty of Chemical & Natural Resources Engineering Project paper (Bachelor of Chemical Engineering) -- Universiti Malaysia Pahang – 2015 Bibliography : p. 49-59 Extraction (Chemistry) THE0004043(Local) UMP 150922 20251117113302.0 vtls000091293
