Is there a catalyst that can separate glycerin?
In the production of bio-diesel and glycerol from the transetherification of jatropha oil with methanol in the presence of silica gel as the catalyst, I want to know if there is a catalyst that can separate the glycerin from the bio-diesel without the conventional method of allowing the heavier liquid to settle or the application of centrifugation?

Damaged sieve trays
It is urgent to know the main reason why our top sieve tray in the extractor is damaged. Its function is to extract mercaptan in LPG with a caustic, but during annual shut-down it is shown that the top trays are damaged. I need to know the main reason for the damaged sieve trays.

Processing costs comparison
Is there a template for comparing the processing costs of extraction versus distillation with rectification? Optima is a contract manufacturer with two Karr Columns. We would like to point out the advantages of liquid extraction to our customers. With energy costs rising, I would think there are advantages even if both unit operations work.
