Abstract
A hydrocarbon sequestering product, a method to obtain the product, and a method and a facility to sequester hydrocarbons, wherein the product comprises an oleophilic filamentous material that gets in contact with a medium contaminated by one or more hydrocarbons with the purpose of sequestrating the hydrocarbon(s) present in the medium to free it from said hydrocarbons.
Claims24
A method to sequester hydrocarbon from a medium contaminated by said hydrocarbon, said method comprising:
- a. placing a hydrocarbon sequestering product comprising ground oleophilic filaments in micro-particle or powder form in contact with said contaminated medium, said product comprising sterilized and stabilized ground feather-filaments, said ground feather-filaments having no quills and obtained from feathers by:
- grinding the feathers-filaments to produce a ground product free from quills,
- sterilizing the ground product;
- stabilizing the ground product;
- maintaining a natural oily property of the feather filaments by application of an aqueous emulsion, and
- b. maintaining said hydrocarbon sequestering product in contact with said contaminated medium for a period of time such that at least some hydrocarbon is freed from said medium.

A method to protect a medium from hydrocarbon contamination, said method comprising:
- a. placing a hydrocarbon sequestering product comprising ground oleophilic filaments in micro-particle or powder form in contact with said medium to be protected;
- b. placing said product so that the product lies between said medium and a source of said contamination;
- c. said product comprising sterilized and stabilized ground feather-filaments, said ground feather-filaments having no quills and obtained from feathers by:
- grinding the feathers-filaments to produce a ground product free from quills,
- sterilizing the ground product,
- stabilizing the ground product, and maintaining a natural oily property of the feather filaments by application of an aqueous emulsion.
