Effluent Stream

The monitoring of the effluent of a rotary dryer has been developed and implemented. The vapor stream between the dryer and the vacuum is monitored in real time by a process fiber-optic coupled near-infrared (NIR) spectrometer. A partial least-squares (PLS) calibration model was developed on the basis of solvents typically used in a chemical pilot plant and uploaded to an acousto-optic tunable filter NIR (AOTF-NIR). The AOTF-NIR is well suited to process monitoring as it electrically scans a crystal and hence has no moving parts. The AOTF-NIR continuously fits the PLS model to the currently collected spectrum. The returned values can be used to follow the drying process and determine when the material can be unloaded from the dryer. The effluent stream was monitored by placing a gas cell in-line with the vapor stream. The gas cell is fiber-optic coupled to a NIR instrument located 20 m away. The results indicate that the percent vapor in the effluent stream can be monitored in real time and thus be used to determine when the product is free of solvent.

Pabrik pupuk SRF kapasitas 10.000 ton/tahun berlokasi di Kabupaten Bantaeng, merupakan pilot plant percontohan bagi sektor pertanian di Indonesia. Sistem pengering terdiri 3 rotary dryer (RD). RD I dan II berfungsi sebagai pengering sedangkan RD III sebagai pengkondisian produk sampai kondisi atmosferik. Sistem pengering dirancang untuk menurunkan kadar air dari 8,18% menjadi 1,87%. Sejak pabrik dibangun, sistem belum beroperasi optimal sehingga kualitas produk sesuai desain belum dicapai. Tujuan dari penelitian ini adalah mengoptimasi desain termal sistem pengering agar menghasilkan produk sesuai desain dan hemat energi. Optimisasi dilakukan dengan mengganti bahan bakar kerosin menjadi solar, pemasukan udara tersier secara siklon, dan pemasangan pengaduk dengan kemiringan. Penelitian dilakukan dengan menghitung kesetimbangan panas dan massa di dalam sistem dan simulasi aliran media pengering menggunakan perangkat lunak CFD. Hasil perhitungan mengindikasikan agar sistem pengering bekerja optimal, RD I dan RD II memerlukan suplai udara tersier masing-masing sebesar 8004,23 kg/jam dan 6171,29 kg/jam, dan konsumsi solar masingmasing 13,1 kg/jam dan 14,3 kg/jam. Aliran masuk media pengering melalui cyclone-nozzle menghasilkan profil aliran yang berpusar sepanjang pengering, yang akan menghasilkanproses pengeringan lebih efektif, dan terbukti aman terhadap kondensasi uap air pada sisi keluar.Kata kunci: pupuk SRF, rotary dryer, desain, simulasi, optimasi, CFD

And Performance

Rotary dryers are commonly used to dry particulate in a range of food and mineral processing industries. The purpose of this work was to study the design and performance of a rotary dryer. It was evaluated the number of flights and operational conditions that corresponding to the optimal performance for the equipment. A set of equations to predict the solids holdup in flights with three and two segments was also evaluated. Their predictions were compared to measurements performed with a pilot plant rotary dryer. The equation generated very accurate estimations.
