The present invention discloses a process and an apparatus for conversion of waste plastic pyrolysis oil into value added products, wherein, the pyrolysis oil is produced from waste plastics by utilizing HCGO as a preheating stream. The process and apparatus as disclosed improves the conventional DCU process in terms of liquid, gaseous yields and reduction in coke yields and without disturbing the hardware of the conventional process along with energy efficient production of pyrolysis oil. The present process and apparatus include a delayed coking process and a system for the delayed coking process which involves the integration of delayed coking system with pyrolysis section and utilization of produced pyrolysis oil by co-processing it with residual heavy hydrocarbon feedstock.

Process and an apparatus for conversion of waste plastic pyrolysis oil into valuable products

The present invention relates to a process and system for complete conversion of crude oils by integrating Desalter unit, Atmospheric and vacuum column, high severity FCC process, Naphtha cracking process, residue slurry hydrocracking process, Delayed coking process, Selective mild hydrocracking aromatic production unit, Dehydrogenation units, Aromatic/olefin recovery section, gasifier unit along with syngas to olefins conversion section.

Integrated process for converting crude oil to high value petrochemicals

The furnace of a delayed coking unit which is utilized for heating residue feeds to high temperatures can suffer from decrease in run length and fouling caused by caustic carryover from the upstream desalter unit. An antifoulant additive for preventing caustic induced fouling of thermal cracker furnace tubes is disclosed. The described antifoulant additive acts by converting the inorganic caustic compound such as NaOH to naphthenate salt of the metal as well as by reducing the fouling tendency of the whole feedstock, thereby making it ineffective in causing coking reaction. The additive finds application in thermal residue upgradation furnaces such as delayed coking unit, visbreaker, etc.
