Methanol recovery is the largest steam user on our client’s site. A number of options to reduce steam consumption on a methanol site were investigated using process simulation software to identify the most effective solution to take forward to the detailed design stage.
Over 25% increase in the methanol recovery process capacity
Adding a second distillation column operating in parallel.
Process simulation software was utilised to model this new configuration to aid in the design process and to estimate the benefits.
Benefit to Client
Steam consumption will be reduced by close to 50% and the methanol recovery process capacity will increase by over 25%. Capital costs have been kept low by re-using and modifying redundant equipment.
