Notice of Retraction: Study on Steam Technology for Removing Oleoresin from Masson Pine Wood by Energy Management

Abstract

The technology for removing oleoresin from masson pine wood without waste water is an great market demand. What is worse is that the current consumption of skim a lot of energy technology.The result is as follows: (1)The influence of the sulfur addition on the quantity of dissolved resin is remarkable.The influence of the other factors is not remarkable. (2) The ideal deresination technology is: The sulfur addition is 1-4％, the steaming time is 10-12h，the Na2S2O4·2H2O concentration is 3-5%.
