Modelling and profit maximization of low-density polyethylene in industrial high pressure tubular reactor / Nurzafirah Mohd Supion

Highly exothermic nature of low-density polyethylene (LDPE) polymerization process and expensive cost of heating-cooling equipment in tubular reactor have led to low ethylene conversion and high production costs. Both problems are taken into account when optimizing the LDPE production to obtain the...
