Abstract

A process for producing absorbent materials includes reducing a banana tree stalk into separated fibers, pressing the separated fibers to generate pressed fibers having less than 50% moisture content by weight, reducing moisture content of the pressed fibers by applying infrared heating to produce pre-dried fibers, and applying a non-thermal drying process to generate dried fibers having less than 10% moisture content by weight for employment in an absorbent material that absorbs hydrocarbons.

Claims

1. A process for producing absorbent materials, the process comprising:

reducing a banana tree stalk into separated fibers;

pressing the separated fibers to generate pressed fibers having less than 50% moisture content by weight;

reducing moisture content of the pressed fibers by applying infrared heating to produce pre-dried fibers; and

applying a non-thermal drying process to generate dried fibers having less than 10% moisture content by weight for employment in an absorbent material that absorbs hydrocarbons.

2. The process of claim 1, wherein pressing the separated fibers comprises pressing the separated fibers using a hydraulic press, a screw press or a belt press to remove water, latex, or natural juices.

3. The process of claim 1, wherein pressing the separated fibers comprises generating pressed fibers having opened capillaries for absorption of hydrocarbons.

4. The process of claim 3, further comprising washing the fibers after the pressing.

5. The process of claim 1, wherein reducing moisture content of the pressed fibers comprises passing the pressed fibers proximate to a halogen lamp via a conveyor device.

6. The process of claim 1, wherein a conveyor device is employed to transport one or more of the separated fibers, the pressed fibers and the pre-dried fibers.

7. The process of claim 1, wherein applying a non-thermal drying process comprises employing non-thermal, kinetic disintegration, pulverization.

8. The process of claim 1, wherein applying a non-thermal drying process comprises employing a drying process that employs kinetic energy and airflow, without a heat source, to dry the pre-dried fibers.

9. The process of claim 1, further comprising providing the dried fibers for integration into one or more of a loose absorbent material, a wipe, a rag, a towel, a pillow or a boom.

10. A system for producing absorbent materials, the system comprising:

a reducer configured to reduce a banana tree stalk into separated fibers;

a press configured to press the separated fibers to generate pressed fibers having less than 50% moisture content by weight;

an infrared heating device configured to reduce moisture content of the pressed fibers by applying infrared heating to produce pre-dried fibers; and

a non-thermal dryer configured to generate dried fibers having less than 10% moisture content by weight for employment in an absorbent material that absorbs hydrocarbons.

11. The system of claim 10, wherein the press comprises a hydraulic press, a screw press or a belt press configured to remove water, latex, or natural juices from the separated fibers.

12. The system of claim 10, wherein the press is configured to generate pressed fibers having opened capillaries for absorption of hydrocarbons.

13. The system of claim 10, further comprising a wash assembly for washing the fibers after the pressing.

14. The system of claim 10, wherein the infrared heating device comprises a halogen lamp and a conveyor device.

15. The system of claim 10, further comprising a conveyor device disposed between one or more of the reducer, the press, the infrared heating device and the non-thermal dryer.

16. The system of claim 10, wherein the non-thermal dryer comprises a non-thermal, kinetic disintegration, pulverization device.

17. The system of claim 10, wherein the non-thermal dryer is configured to generate the dried fibers using kinetic energy and airflow, without a heat source.

18. The system of claim 10, wherein the dried fibers are integrated into one or more of a loose absorbent material, a wipe, a rag, a towel, a pillow or a boom.

19. An absorbent material for absorption of hydrocarbons, the absorbent material being prepared by operations comprising:

reducing banana tree stalk into separated fibers;

pressing the separated fibers to generate pressed fibers having less than 50% moisture content by weight;

reducing moisture content of the pressed fibers by applying infrared heating to produce pre-dried fibers; and

applying a non-thermal drying process to generate dried fibers having less than 10% moisture content by weight for employment in an absorbent material that absorbs hydrocarbons.

20. The absorbent material of claim 19, wherein the dried fibers are integrated into one or more of a loose absorbent material, a wipe, a rag, a towel, a pillow or a boom.
