Abstract
Official abstract text for this publication.
The invention is directed to utilization of a series of cross-linked 1,4-benzenediamine-co-alkyldiamine polymers and the use of the polymers to remove mercury from a hydrocarbon in fluid form.
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus for reducing content of mercury in a fluid hydrocarbon, comprising: a container with a fluid hydrocarbon inlet and a fluid hydrocarbon outlet, wherein the container defines a space that contains at least one 1,4-benzenediamine-co-alkyldiamine polymer and the fluid hydrocarbon. 2. The apparatus of claim 1 , that is configured so that the fluid hydrocarbon flows through the container while contacting the at least one 1,4-benzenediamineco-alkyldiamine polymer. 3. The apparatus of claim 1 , wherein the at least one 1,4-benzenediamine-co-alkyldiamine polymer is bound to a porous filter. 4. The apparatus of claim 1 , that comprises: a space, within the container, for mixing the fluid hydrocarbon with particles of the at least one 1,4-benzenediamine-co-alkyldiamine polymer. 5. The apparatus of claim 1 , wherein the container has at least one surface which is coated or lined with the at least one 1,4-benzenediamine-co-alkyldiamine polymer and is configured to be in contact with the fluid hydrocarbon. 6. The apparatus of claim 1 , wherein the at least one 1,4-benzenediamine-coalkyldiamine polymer is bound to one or more sheets through which the fluid hydrocarbon containing elemental or organic mercury can flow. 7. The apparatus of claim 1 , wherein the container is a packed column, a tray-type column, a fixed bed column or a fluid bed column. 8. A system for removing mercury from hydrocarbons, comprising: the apparatus of claim 4 , and a filter, a centrifuge, or a separator to separate the fluid hydrocarbon from the particles of the at least one 1,4-benzenediamine-co-alkyldiamine polymer. 9. A system for removing mercury from hydrocarbons, comprising: the apparatus of claim 1 , and a heater. 10. A system for removing mercury from hydrocarbons, comprising: the apparatus of claim 1 , and a water separator, a particle separator or a dehydrator to remove contaminants from the fluid hydrocarbon. 11. A system for removing mercury from hydrocarbons, comprising: the apparatus of claim 1 , and a tank, a pipe or a flow system connected to the fluid hydrocarbon inlet and/or the fluid hydrocarbon outlet.
