STUDI PERHITUNGAN ALAT PENUKAR KALOR TIPE SHELL AND TUBE DENGAN PROGRAM HEAT TRANSFER RESEARCH INC. ( HTRI )

Irwin Bizzy, Rachmat Setiadi

Abstract


Abstrak

Untuk mengurangi biaya produksi, perancangan alat penukar kalor terlebih dahulu sangatlah efektif dari pada membeli alat penukar yang sudah jadi. Perancangan ini berupa perhitungan dimensi alat penukar kalor tipe shell and tube menggunakan metode analisa komputerisasi Heat Transfer Research Inc. (HTRI) dan metode analisa perhitungan manual. Perhitungan dimensi alat penukar kalor ini bertujuan untuk mengetahui kualitas dari alat penukar kalor berdasarkan koefisien perpindahan kalor keseluruhan, faktor pengotoran, dan penurunan tekanan yang akan terjadi

Alat penukar kalor yang dirancang adalah alat penukar kalor tipe shell and tube 1 (satu) pass shell dan 1 (satu) pass tube aliran berlawanan dengan fluida panas berupa gas ammonia dan fluida dingin berupa air berdasarkan data lapangan yang diperoleh di PT Pupuk Sriwijaya Palembang

Hasil analisa perhitungan dimensi diperoleh bahwa alat penukar kalor yang dirancang sudah memenuhi syarat minimum dari faktor pengotoran yang telah ditetapkan. Kualitas alat penukar kalor akan meningkat sebanding dengan menurunnya nilai faktor pengotoran, menurunnya nilai penurunan tekanan dan besarnya dimensi alat penukar kalor.

 

Kata kunci : Alat penukar kalor, HTRI, dimensi, kualitas

 

Abstract

To reduce production costs, the design of heat exchanger is very effective in advance of buying a ready-made exchanger. The design of a calculation of the dimensions of heat exchanger shell and tube type using computerized analysis method Heat Transfer Research Inc.. (HTRI) and manual calculation methods of analysis. Dimensional calculation of heat exchanger is intended to determine the quality of a heat exchanger based on the overall heat transfer coefficient, fouling factors, and pressure drop will occur.

Designed heat exchanger is a heat exchanger shell and tube type 1 (one) pass shell and 1 (one) pass counter flow tube with a hot fluid and cold fluid ammonia gas form of water based on field data obtained at PT Sriwijaya Palembang Fertilizer.

Dimensional analysis of the calculation results obtained that the heat exchanger has been designed to meet the minimum requirements of the fouling factor has been determined. Quality of the heat exchanger will be increased in proportion to the decrease in the value of fouling factors, the declining value of the magnitude of the pressure drop and heat exchanger dimensions.

Keywords: heat exchanger, HTRI, dimensions, quality
