| dc.description.abstract | The objective of this work was to study the feasibility of recovery N-Methyl-Pyrrolidone (NMP) and acetone solution in cleaning the slider fabrication process in the manufacturing process of hard disk drive by distillation. The operating parameters such as pressure (50 - 500 mbar) temperature (60 - 110 C) and time (20 - 70 minutes) were investigated. The highest purity of solution was ca 98.12 %of N-Methyl-Pyrrolidone at 110 C, 200 mbar with 30 minutes, that it is sufficiently purity to be re-used. This solution could be produced with 0.33 Liter/hour with 405 Baht/Liter (excluding investment cost) that would be saved 565 Baht/Liter and environmentally friendly with clean technology. | en_US |
