Abstract

A method for controlling Pitch and Stickies is disclosed. The method comprises adding hydrophobically modified hydroxyethyl cellulose (HMHEC) and cationic polymers to a cellulosic fiber slurry (pulp) or to a paper process or to a paper making system and results in a higher degree of inhibiting organic deposition and retention of pitch on paper fiber as compared to the inhibition of the individual ingredients. The combination of HMHEC and cationic polymers surprising results in a synergistic effect.

Claims (18)

1. A method for inhibiting the deposition of organic contaminants in pulp and papermaking systems which comprises treating the pulp and papermaking systems with:
a) a hydrophobically modified hydroxyethyl cellulose; and b) a cationic polymer.
2. A method according to claim 1, wherein the hydrophobically modified hydroxyethyl cellulose has hydrophobes between 8 and 22 carbon atoms in length.
3. A method according to claim 1, wherein the cationic polymer has a molecular weight between 100,000 and 1,000,000.
4. A method according to claim 3, wherein the molecular weight of the cationic polymer is a between 200,000 and 750,000.
5. A method according to claim 1 wherein the ratio of hydrophobically modified hydroxyethyl cellulose to the cationic polymer is in the range of about 1 to 10 to about 10 to 1.
6. A method according to claim 1, wherein the hydrophobically modified hydroxyethyl cellulose and the cationic polymer are delivered to the pulp and papermaking system or to the pulp in a carrier solvent.
7. A method according to claim 6, wherein the carrier solvent is water.
8. A method according to claim 1, wherein the hydrophobically modified hydroxyethyl cellulose and the cationic polymer are delivered to the pulp and papermaking system or to the pulp as a powder or a slurry
9. A method according to claim 1, wherein the hydrophobically modified hydroxyethyl cellulose and the cationic polymer are added to the pulp and papermaking system or to the pulp by spraying.
10. A method according to claim 9, wherein the hydrophobically modified hydroxyethyl cellulose and the cationic polymer are sprayed onto the paper machine wire, paper machine felt, paper machine press roll or other surfaces prone to deposition.
11. A method according to claim 1, wherein the cationic polymer and the hydrophobically modified hydroxyethyl cellulose are added to the pulp and papermaking system or to the pulp with the furnish.
12. A method according to claim 1, wherein the deposition of organic contaminants occurs on the surfaces of the pulp and papermaking systems or of the repulping systems exposed to whitewater or the pulp slurry.
13. A method according to claim 1, wherein the hydrophobically modified hydroxyethyl cellulose and the cationic polymer are added to the papermaking systems with other papermaking treatments.
14. A method according to claim 1, wherein hydrophobically modified hydroxyethyl cellulose and the cationic polymer are added to the paper machine stock or added directly to the contamination prone surface.
15. A method according to claim 12, wherein the surface is selected from paper machine wire and paper machine wet felt.
16. A method according to claim 1, wherein the hydrophobically modified hydroxyethyl cellulose is added to the system before the cationic polymer is added.
17. A method according to claim 1, wherein the cationic polymer is added to the system before the hydrophobically modified hydroxyethyl cellulose is added.
18. A method according to claim 1, wherein the cationic polymer and the hydrophobically modified hydroxyethyl cellulose are added to the system simultaneously.
