Kolom distilasi di atas reaktor ester I untuk memurnikan air dari ethylene glycol (EG) di PT. X adalah tidak efisien karena masih memerlukan proses pemurnian Iagi untuk reaktor yang Iain. Untuk itu diperlukan perancangan awal mengganti kolom distilasi di atas reaktor ester I. Sehingga proses distilasi hanya pada satu kolom yang beroperasi secara kontinyu mengikuti proses produksi poly ethylene terephthalate (PET) dengan demikian proses EG recovery tidak diperlukan lagi.
Perancangan awal kolom distilasi di PT. ...

ABSTRAK
Reduction of free fatty acid (FFA) in used palm oil was determined after treatment of waste cooking oil with an adsorbent derived from coffee bean husk ash. Coffee husks were burned at 600 ºC for 12 hrs to obtain the adsorbent ash. Free fatty acid removal efficiency was optimized with respect to ash dosage, contact time and temperature. It was found that shaking ash (1 g) with waste palm oil (50 g) at 250 rpm ...

The volatile chemicals from species of wild Cinnamomum spp. (C. racemosum, C. cuspidatum, C. politum, C. javanicum), Etlingera spp. (E. pyramidosphaera, E. megalocheilos, E. coccinea, E. elatior) and Schizostachyum spp. (S. blumei, S. brachycladum, S. lima, S. pilosum) found in Sabah were investigated. The oils were obtained from the bark, rhizome and culm of respective specimens by hydrodistillation and the profile of volatile chemicals was obtained using Gas Chromatography- Mass Spectrometry (GCMS). Dominance of eucalyptol, ...
