The work began with   some  characterization  studies  to  provide  understandings  of  fundamental  issues  such  as formation,  formulation  and  breaking  of  emulsions  by  both  conventional  and   environmentally friendly chemicals approaches. ASTM column separation was utilized   for  SARA-fractionation  technique  to  characterize  crude  oil  into  saturates,  aromatics,   resins  and  asphaltenes  compounds.  The  aim  was  to  obtain  an  optimized  operating   condition  as  well  as  fundamental  understanding  of  water-in-crude  oil  stability  upon   which  further  developments  on  demulsification  processes  could  be  developed.  The   stability  studies  were  carried  out  by  analyzing  operating  conditions  such  as  emulsion   processing time, droplet size, types and concentration of surfactants, water-oil ratio and   stirring  intensity.  In  the  demulsification  part,  this  study  also  investigated  the   performances  of  four  functional  groups  of  chemical  demulsifiers  which  were  amine,   polyhydric  alcohol,  alcohol  and  biodegradable  functional  groups.  For  chemical   screening,  One  Factor  at  A  Time  (OFAT)  method  adopted.  Three  crude  oils  namely,   crude  oil  A,  B,  and  C  were  utilized.  These  crude  oils  were  obtained  from  Petronas   Penapisan  Melaka,  Malaysia.  Among  of  these  oils,  crude  oil  C  was  found  to  be  the   heaviest  and  best  for  stability  and  followed  by  crude  oil  B  and  A  respectively.  For   chemical  demulsifiers,  results  show  that  octylamine  was  the  best  for  water  separation   (99  %  at  day-one)  and  followed  by  palm  based  oleyl  amine  (PBOA)  (99  %  at  day-  three),  hexylamine  (98  %  at  day-five)  and  coca  amine  (97.5  %  at  day-five).  For   optimization  part,  the  response  surface  methodology  (RSM)  was  utilized  and  results   showed  that  the  optimum  conditions  for  each  crude  oil.  The  results  obtained  in  this   study  have  exposed  the  capability  of  chemicals  (conventional  and  environmentally   friendly)  method  in  breaking  of  water-in-crude  oil  emulsion.  Further  works  are   nevertheless  required  to  provide  deeper  understanding  the  mechanisms  involved  to   facilitate the development of an optimum system applicable to the industry. 0aDemulsification40uhttp://ecollib.ump.edu.my/25058/zLibrary access only  00102lcc4071a10000b10000d2019-09-04l0oTP156.D42 N87 2012 rs Thesisp0000066301r2019-09-04 00:00:00t1w2019-09-04yTHESIS  00102lcc4071a10000b10000d2019-09-04l0oCD 6206 | TP156.D42 N87 2012 rs Thesisp0000066302r2019-09-04 00:00:00t1w2019-09-04yTHESIS  aVIRTUA40c2492d2498  aVTLSSORT0080*0200*0400*0900*1000*2450*2600*3000*5020*5040*5200*6500*8560*9992
