Abstract
ABSTRACT The evaporator is a unit that serves to economize on the use of solution used during the production of tin plate. Solvent drag out tanks stored in the storage tank will be pumped into the evaporator unit to the separation between the solution with water. The resulting solution will be pumped back to the storage tank circulation 1 and 2 while the produced water is used for the addition of water in the tank working drag out 1 and 2 to maintain concentration. During the coating solution at a concentration dioprasikan special stannous tin and the concentration of free acid, the excess water and drag out a solution must be removed with a rotary evaporator. There are several main parts evaporator units, one of which Plate Heat Exchangers (PHE) which serves to raise the desired temperature, in this case around 58-62 degrees Celsius. In the selection of material has previously been determined that the plate heat exchanger using 316L SS materials that last for about 5 years and titanium Hanaya last approximately 3 months. Then in select return using the formula of pitting resistance equivalent number (prEN) that the material can SMO 254, but can be seen in the economically replaced with the 304 SS lined with Crom. Keywords: pitting corrosion, austenitic stainless steel, Material selection

| Additional Information: | ABSTRAK Evaporator merupakan suatu unit yang berfungsi untuk melakukan penghematan penggunaan solution yang digunakan selama proses produksi tin plate. Larutan drag out tank yang disimpan dalam storage tank akan dipompakan kedalam evaporator unit untuk dilakukan pemisahan antara solution dengan air. Solution yang dihasilkan akan dipompakan kembali ke storage circulation tank 1 dan 2 sedangkan air yang dihasilkan digunakan untuk penambahan air di working tank drag out 1 dan 2 untuk menjaga konsentrasi. Selama larutan pelapisan dioprasikan pada konsentrasi timah stannous yang khusus dan konsentrasi asam bebas, maka kelebihan air dan larutan drag out harus dikeluarkan dengan evaporator. Ada beberapa bagian utama evaporator unit , salah satunya Plate Heat Exchanger (PHE) yang berfungsi untuk menaikan temperature yang diinginkan, dalam hal ini sekitar 58-62 derajat celcius. Pada pemilihan material sebelumnya telah ditentukan bahwa plat heat exchanger menggunakan bahan SS 316 L yang bertahan selama kurang lebih 5 tahun dan titanium yang bertahan kurang lebih hanaya 3 bulan. Kemudian di pilih kembali menggunakan rumus pitting resistance equivalent number ( PREN ) bahwa di dapat material SMO 254 , akan tetapi melihat dari segi ekonomis bisa di diganti dengan SS 304 yang di lapisi dengan crom.
