Pyrolysis oil fractionation can be a landmark in waste monetization by converting pyrolysis oil into value added products such as naphtha, diesel and base oil. Pyrolysis oil is obtained from waste plastic and tyre through a process known as pyrolysis. Although pyrolysis oil is currently sold and used as fuel oil, its value is less than other high value pteroleum products such as petrol and diesel. However, it can be fractionated into value added products such as naphtha, diesel and base oil in a series of two distillation columns, one the atmospheric column and other the vacuum column.

Satsha Management Services is probably the first in India to conceptualize the process of Pyrolysis oil fractionation and perform the pre-feasibility study on pilot plant scale for one of our esteemed clients, Pyrocrat Systems LLP, Mumbai. If implemented, the process can be a landmark in value maximization of the waste.

The distillation curve data of pyrolysis oil varies from oil to oil. Typically, its IBP is 61 ºC and FBP 633 ºC. The expected yield (by weight) from distillation is:

Naphtha: 22.3%
Diesel: 45.1%
Base oil: 27.4%
Residue: 5.1%

Satsha Management Services has delivered a two-day industrial workshop on ‘Pressure Safety Valve (PSV): Fundamentals, Design, Sizing and Parameters’ on 15th and 16th December 2017 at Kolkata. The program was delivered by its proprietor-Satyendra Kumar Singh. Participants from Tata Chemicals Limited, Haldia and Numaligarh Refinery Limited, Numaligarh attended the workshop. The participants acquired knowledge and learnings from the workshop in respect of various aspects of PSV such as concepts and basics of PSV, functions of PSV, need and importance of PSV in Process design, layer of protection analysis (LOP), operations and types of PSV, identification of various upset scenarios, PSV relieving rate and sizing calculations, etc.
