Process flow diagram of production of Ethylene

Ethylene Production by Naphtha Cracking Technology

Ethylene largely consumed in production of polyethylene (HDPE, LDPE and LLDPE) and used as a major feedstock for the manufacture of Ethylene Di-chloride, Polyvinyl Chloride, Vinyl Chloride and Ethylene Oxide (EO). Modern petroleum refinery generates ethylene from its process units along with gasoline, naphtha, diesel etc. Naphtha from the refineries widely transported to petrochemical plants…

Acetylene production technology

C2H2 is a compound having four atoms i.e, 2 atoms of carbon and 2 atoms of hydrogen, acetylene is highly unstable and explodes with mechanical shock. Acetylene is stored in liquid form with the help of acetone; it dissolves in acetone under applied pressure between 12 to 15 atm and the risk of explosion can…

Dissolved oxygen determination methods and calculations

Dissolved oxygen parameter indicates the biological activity in water. It is one of the spec measurement used for knowing the condition of wastewater. Two familiar methods are used for dissolved oxygen determination in wastewater. Winkler’s method (chemical analysis) Polarographic method Sample for testing Dissolved Oxygen (DO) should be minimum 250ml. Water sample should be collected…

Controls used to optimize the ideal binary distillation column operation

Ideal binary distillation column optimization┬ádepends on the process control principles of feedback, feedforward, and hill climbing methods. For particular continuous distillation operation (olefins purification) both method can be used simultaneously by the optimum operation parameters. Each method as it own different advantages and to finding out the best of it, is important task of the…
