Taiwan-based Sunho Biodiesel Corp. is offering a free lipase biocatalyst to clients that license and set up a biodiesel plant based on the Sunho’s ET Process®.
When considering a process for industrial production of a commodity, two major criteria are process reliability and cost of consumables. This is where the ET Process® offers distinctive advantages. The design of the ET Process® allows the system to optimize its efficiency. It runs in an automatic, continuous manner. There is no need for the producer to conduct numerous trial-and-error adjustments since it is a well-designed process. The use of inert solvent prevents lipase poisoning and deactivation from glycerol, methanol and water and stabilizes lipase activity. Due to the improvement in life span, the catalyst does not have to be replaced frequently, leading to significant catalyst cost savings. From recent market data, it was found that the lipase consumption of enzymatic processes that use either immobilized or liquid lipase without inert solvent is one order of magnitude higher than that of the ET Process®. Based on a plant with a capacity of 10,000 T/yr biodiesel, the former processes will consume more than 12-20 T/yr of biocatalyst, while the ET Process® will consume only 1 T/y or less. This means that in a two-year span, the cost difference in lipase expense between retrofitting an existing plant using the aforementioned processes and using the ET Process® is much higher than the capital investment needed to set up a new ET Process® plant.
Sunho is offering the biocatalyst to biodiesel plants that will have a capacity of at least 5,000 tonnes/yr based on degummed oil. The biocatalyst will be supplied for the first 18 months or in 3 batches, depending on which one comes first.
