  • PROCESS AND APPARATUS FOR THE PRODUCTION OF SULPHUR OXIDES
    Publication number: 20080038184
    Abstract: The invention is directed to a process and apparatus for the removal of hydrogen sulphides from streams containing them, in particular from wastewater streams. According to the invention, hydrogen sulphide is stripped from the process liquid by means of a vacuum stripper. The gas thus produced has a high H2S content, which facilitates further processing.

  • RECOVERY OF SULPHURIC ACID
    Publication number: 20080025911
    Abstract: The invention is directed to a process for the recovery of sulphuric acid from a mixture comprising sulphuric acid and hydrocarbons, in particular carbohydrates. In accordance with the present invention the mixture comprising sulphuric acid and carbohydrates, is contacted with an anion selective membrane, thus producing a sulphuric acid rich filtrate stream and a stream depleted in sulphuric acid.

  • PROCESS AND APPARATUS FOR THE CONVERSION OF BIOMASS
    Publication number: 20080022997
    Abstract: The invention is directed to a process for the conversion of cellulosic biomass, in particular lignocellulose-containing biomass into fermentable sugars. The invention is further directed to apparatus suitable for carrying out such processes. According to the invention biomass is converted into fermentable sugars by contacting in a reactor said biomass with an acid, while passing an inert gas stream capable of taking up water through said reactor, by which the pH in said reactor can be controlled.
