Abstract

ANALISA KINETIKA REAKSI PEMBENTUKAN KERAK CaCO3-CaSO4 DALAM PIPA BERALIRAN LAMINAR PADA SUHU 30 C MENGGUNAKAN PERSAMAAN ARRHENIUS 0 0 C DAN 40 HARYONO Teknik Mesin-Fakultas Teknik- Universitas Muhammadiyah Semarang Jl. Kasipah no.12 Semarang 50254 E-mail : haryonobenos@gmail.com The crust is a hard pile of inorganic material especially on the heat transfer surface caused by deposition of mineral particles in water. Know the reaction rate constant and activation energy of CaCO3-CaSO4 scale formation with Arrhenius equation. The higher the temperature makes the crust more and more formed. At a temperature of 30 C produces a crustal mass of 38.1 mg while at 40 0 0 C the resulting crust mass is 58.5 mg. The higher the temperature makes the value of the reaction speed constant rising. At 30 C the resulting reaction rate constant is 1,195 kJ.mg1.C-1. While at a temperature of 40 0 C yields a reaction rate constant of 3.737 kJ.mg-1.C-1. The activation energy in the CaCO3-CaSO4 crust formation reaction is 123.23 kJ. From SEM results between no additions and with the addition of cubical morphological forms with rombohedral and monoclinic crystal structures. 0 Keywords: Crust, CaCO3, CsSO4, SEM
