Design aspects of used lubricating oil re-refining by modern process
presents of feasible and comprehensive technology for recycling used lubricating oil. wiped film evaporator and lube oil polishing system are main components of this process
that optimized piping engineering team Wiped film Evaporators to produce higher process efficiencies by minimizing bottom components and maximizing reclamation/regeneration of the useful ingredients from used lube oil.
WFE
The high yield in the WFE process is due to innovative equipment design and design optimizations of the process. WFE process is acid-free and sludge-free. The bottom residue generated in the process can also be sold as a finished product, such as asphalt/bitumen modifier. WFE adapts very well to feedstock variability such as used lube oils containing a high amount of water.
process

Technical challenges
NOTE: Material Requisition (MR) hours are excluded as part of Electrical estimation Challenges & Approach
Technical Challenge:
such as the Absence of checklist for IFC, ISO for project deliverables
Our Solution:
our Eng team exclusively created it for the customer based on their prior experience by plotted it till the end of the project and even resolved customer queries in this reference
Technical Challenge:
Process Plant Layout was very complicated with limited space to move the equipment easily.
Our Solution:
such as the Engineering based on their prior experience without compromising on the deadline or project schedule o Created an alternative plan/approach and reviewed it with the customer to ensure the quality of deliverables are met o Pipe standards were rearranged/realigned as per the requirement
Technical Challenge:
No proper tracking of deliverables vs. output
Our Solution:
Helped with the creation of a structure to accurately not just plot it, but it helped streamline the process.
Technical Challenge:
Customer didn’t have proper pipe support standard
Our Solution:
our team created a cost-effective pipe support standard, which enabled the customer to meet the end deliverables. It helped them get adequate cost savings Project Execution Process
