Design of Polypropylene Distillation Fuel Generator (PDFG) as an effort to create alternative energy for standar engine

Abstract

Technologies  Energy like  fossil  energy  belong  to  renewable  energy  are growing. one of the example is to recycle of waste plastic as fuel .Some types of waste that we often see are plastic bottles such as plastic cups, plastic bottle caps, toys and margarine  etc., which  is  one  type  of  PP Polypropylene waste.  Each  unit of  heavy plastic can produce 70 percent oil, 16percent gas, 6 percent carbon solid and 8 percent water.  And  for  PP  type  plastic  Polypropylene has  melting  point  of  70celcius  degree until 80celcius  degree [5][11][12].  The  calorific  value  of  pure  Polypropylene  Liquid Plastics BBPP is 25.97 KJ per gram. Proving that plastic waste has a high enough heat content  it  can  be  developed  to  become  one  of  the  alternative  sources  of  energy  that uses renewable natural materials renewable resources, although in previous studies the calorific value obtained was still below the standard reference fuel value of 48 KJ per gram.  So  it  still cannot be  used  on  motor  vehicles.  This  study  aims  to  increase  the calorific  value  of liquid  polypropylene  fuel  from  the  results  of  Pyrolysis  so  that  the calorific value is closer to the standard by using the distillation process and absorption method or purification process of purifying the Polypropylene liquid fuel. Liquid fuel Polypropylene  is  introduced  into  the  Absorption  Distillation  reactor  and  evaporated using  a  heater  to  a  temperature  near  70celcius  degree until 90celcius  degree.  and subsequently  condensed  by  using  a  pure  water  medium  with  a  temperature  of 20celcius  degree  until 25 Celsius  degree.  The  calorific  value  resulting  from  the absorption  distillation  is  44.35  KJ per gram.  The  results  are  close  to  the  standard premium fuel calorific value.
