Publication number: 20230159418Abstract: An apparatus and process for distillation of methanol which may also be used in distillation of other products, such as ethanol. The apparatus and process have the purpose of reducing the consumption of energy and of cooling water and/or electricity in a distillation process of crude intermediate products, including a pre-treatment stage, known as stabilizing stage, for the removal of the volatile components, and a concentration stage, including one or more columns for distillation.Type: ApplicationFiled: June 23, 2021Publication date: May 25, 2023Applicant: TOPSOE A/SInventors: Esben Lauge SØRENSEN, Per Juul DAHL, Tais Bjerg CLARIDGE, Johannes QUINTERO

Patent number: 11341691Abstract: The present invention provides a method of computer analysis of a data set representing an image to extract a texture based measure therefrom, said image including a multiplicative bias in intensity within the image of unknown magnitude, the method comprising applying to said data set a bank of texture extracting filters, such that said filters are chosen from filters that are invariant to the presence of a multiplicative bias field. By providing such a method, rather than attempting to correct the bias field before extraction of a texture based-biomarker, a texture-based biomarker that is bias field invariant is extracted. This makes correction of the bias field unnecessary.Type: GrantFiled: May 12, 2016Date of Patent: May 24, 2022Assignee: CEREBRIU A/SInventors: Lauge Sørensen, Mads Nielsen, Christian Igel

Patent number: 10332241Abstract: Computer analysis of data sets representing images such as MRI images to achieve bias correction and image registration, each image including a bias in intensity within the image of unknown magnitude, is performed by: a) inputting a digital data set of a first image and a digital data set of a second image into a computer; b) calculating a deformation of said first image that transforms said first image into a transformed image that is an optimized approximation of said second image and c) simultaneously calculating and applying a bias correction which is applied to said first image and a bias correction which is applied to said transformed image such that each of the first image and the transformed image is individually corrected for bias therein. Generally, an average of the bias correction over the first image is equal and opposite to an average of the bias correction over said transformed image.Type: GrantFiled: September 16, 2015Date of Patent: June 25, 2019Assignee: BIOMEDIQ A/SInventors: Bin Zou, Akshay Sadananda Uppinakudru Pai, Lauge Sørensen, Mads Nielsen

Patent number: 8598238Abstract: A process for the preparation of hydrocarbon products comprising the steps of (a) providing a synthesis gas comprising hydrogen, carbon monoxide and carbon dioxide; (b) reacting the synthesis gas to an oxygenate mixture comprising methanol and dimethyl ether in presence of one or more catalysts which together catalyse a reaction of hydrogen and carbon monoxide to oxygenates at a pressure of at least 4 MPa; (c) withdrawing from step (b) the oxygenate mixture comprising amounts of methanol, dimethyl ether, carbon dioxide and water together with unreacted synthesis gas and introducing the entire amount of the oxygenate mixture without further treatment into a catalytic oxygenate conversion step (d); (d) reacting the oxygenate mixture in presence of a catalyst being active in the conversion of oxygenates to higher hydrocarbons; (e) withdrawing an effluent from step (d) and separating the effluent into a tail gas, a liquid hydrocarbon phase containing the higher hydrocarbons produced in step.Type: GrantFiled: June 3, 2010Date of Patent: December 3, 2013Assignee: Haldor Topsoe A/SInventors: Finn Joensen, Poul Erik Højlund Nielsen, Esben Lauge Sørensen

Patent number: 8377386Abstract: Flow deflector that is capable of changing the flow direction of a fluid during passage through a duct. The duct is formed by an inner and outer duct, which creates an annular region in the duct. The flow deflector forces the fluid passing through the annular region of the duct to flow inside the inner duct, while the fluid passing through the inner duct is forced to flow through the annular region. Reactor tubes for catalytic reactors are formed by assembling tubes comprising said flow deflector and having a catalyst arranged in the inner tube.Type: GrantFiled: March 5, 2009Date of Patent: February 19, 2013Assignee: Haldor Topsoe A/SInventors: Jesper Norsk, Esben Lauge Sørensen, Niklas Jakobsson
