Title: Innovations by Inventor Stefan Andersen
Introduction
Stefan Andersen is a notable inventor based in Albertslund, Denmark. He has made significant contributions to the field of hydrocarbon processing, holding 2 patents that showcase his innovative approaches to gas-to-liquid processes and hydrocarbon upgrading.
Latest Patents
One of his latest patents is titled "Process for conversion of a hydrocarbon stream." This invention relates to a process plant and a method for upgrading a hydrocarbon mixture withdrawn directly from a crude distillation unit. The process involves several steps, including directing the hydrocarbon mixture to a vacuum flasher unit, withdrawing heavy and light hydrocarbon fractions, and hydrocracking the light hydrocarbon mixture in the presence of hydrogen. This method effectively limits the amount of asphaltenes, metals, and other heavy components that come into contact with the catalytic material during hydrocracking.
Another significant patent by Andersen is the "Method for starting-up a gas to liquid process." This invention outlines a process for initiating a gas-to-liquid process that includes the production of synthesis gas. The synthesis gas is produced using autothermal reforming or catalytic partial oxidation. During the startup phase, the effluent gas is modified to create an off-gas recycle that is fed back into the reforming process. Once the downstream GTL process is operational, the recycle shifts to its off-gas.
