Abstract

Alat penukar panas merupakan serangkaian alat untuk menghasilkan perpindahan panas dari fluida satu ke fluida lainnya. Penelitian ini bertujuan untuk merancang suatu alat penukar panas tipe shell and tube 1-2 dengan aliran co-current hingga didapatkan nilai efektivitas dari alat penukar panas yang dirancang. Perhitungan rancangan menggunakan fluida panas berupa air 80 °C yang dilewatkan pada sisi shell dengan kecepatan 50 ml/s dan fluida dingin berupa air 30 °C yang dilewatkan pada sisi tube dengan kecepatan 20 ml/s. Alat penukar panas dirancang dengan panjang total 800 mm dilengkapi dengan 18 buah tube yang disusun secara triangular dengan OD 3/8” dan panjang 600 mm. Material yang digunakan untuk konstruksi tube yaitu stainless steel 3/8” dan shell yaitu stainless steel 4” sch 40. Selanjutnya dilakukan perhitungan untuk mengetahui efektivitas dari alat penukar panas yang dirancang. Alat penukar panas tipe shell and tube yang dirancang layak dan aman digunakan karena memenuhui standar keamanan alat penukar panas yaitu nilai fouling factor (Rd) 0,016386 hr.ft2.°F/BTU 0,002 hr.ft2.°F/BTU, nilai ΔPS0,00105 psi 10 psi dan nilai  ΔPT 0,01086 psi 10 psi dan memiliki efektivitas sebesar 72,49 %.Kata kunci: desain, alat penukar panas, shell and tube, efektivitas.

Abstract

The liquid waste of the food industry has recently increased. Therefore, when it is discharged into the waters, it will cause turbidity and can damage the ecosystem inside. One of the wastewater treatment techniques is absorption using biosorbents, one of which is made from coconut fiber to reduce the color intensity of the liquid waste. The purpose of this study was to determine the effects of the coconut fiber biosorbent on the color intensity, COD, and pH of the liquid waste of the food industry. In this research, the coconut fiber was delignified with a 2 M NaOH solution and then activated with a 3 N solution. The research variables consisted of the weight percentages of biosorbent by 1%, 2%, 3%, 4%, and 5%, and the contact time of 30 and 60 minutes with shaker stirring. Meanwhile, the most optimum results in COD removal happened at the addition of 4% for 60 minutes, from the initial COD of 1179 mg/L O2 to 780 mg/L O2 within the removal of 26.5%. The highest pH removal of 6.98 occurred in the variable addition of 1% for 30 minutes, whereas the lowest pH removal of 6.5
