Distillation and separation technologies

Improve performance and minimize expenditure. Refinery operators want to improve their distillation performance to optimise their assets, minimise their expenditure and capital investment, and debottleneck their operations. Through the licensing of bulk crude distillation units, high-vacuum units, work-up sections for upgrading units and column and vessel internals, Shell Global Solutions can help refiners to achieve these objectives.
 
The Shell Group (“Shell”) has particular strengths in fluid science and technology: separation vapour–liquid relationships, flow regimes and phase mixing. Shell Global Solutions provides technical support in primary distillation, phase separation and membrane technology. Our expertise has been developed from extensive operational experience within Shell in exploration and production, and in more than 40 refineries and gas and chemical plants across the world.
 
The high-vacuum process lies at the core of the Shell Global Solutions offering. Our deep-flash, high-vacuum units help to maximise the recovery of distillate (waxy distillate or vacuum gas oil) from long residue. This fraction has beneficial properties as feedstock for a catalytic cracker or hydrocracker unit. A fraction suitable for the refinery diesel pool is also produced.
 
Shell Global Solutions’ technology enables operators to blend condensate with normal crude for running in their refineries or for processing in condensate splitters, which helps them meet the demand for premium fuels. When condensate is processed through a splitter, it produces around 50% naphtha and a large portion of diesel.
 
Shell ConSep* trays have been applied in 10 distillation unit revamps. Shell HiFi* trays have been used in more than 100 applications for super-fractionators and other olefin processes.
 
Have you considered how you can
· maximise distillate recovery from long residue?
· raise capacity without compromising on efficiency or reliability?
· prevent excessive cracking in your high-vacuum-unit furnace?
