Method of removing tacky substance or waste liquid containing tacky substance
View Patent ↗A method of removing a sticky substance or a waste liquid containing a sticky substance which comprises, mixing a solid substance having inflammability and liquid-absorptivity into the sticky substance or the waste liquid containing the sticky substance wherein these are mixed to allow a liquid component of the sticky substance or the waste liquid containing the sticky substance to be absorbed into the solid substance and to allow the sticky substance to be entangled with the solid substance, and then removing the sticky substance together with the solid substance.
1. A method of removing a sticky substance or a waste liquid containing a sticky substance which comprises:
mixing a solid substance having inflammability and liquid-absorptivity into a sticky substance or a waste liquid containing a sticky substance wherein these are mixed to allow a liquid component of the sticky substance or the waste liquid containing the sticky substance to be absorbed into the solid substance and to allow the sticky substance to be entangled with the solid substance,
wherein the sticky substance or waste liquid containing the sticky substance is a partially polymerized substance or waste liquid containing a partially polymerized substance generated in a process of production, distillation, purification or storage of an easily-polymerizable substance,
and then removing the sticky substance together with the solid substance or the waste liquid containing the sticky substance together with the solid substance.
2. The method according to claim 1 , wherein the liquid component of the sticky substance or the waste liquid containing the sticky substance to be absorbed into the solid substance are mixed with the solid substance to allow the sticky substance to be entangled with the solid substance, and as a result, stickiness of the mixture is lowered so that the mixture can be handled like a solid.
3. The method according to claim 1 , wherein the sticky substance is a partially polymerized substance or the waste liquid containing the sticky substance is a waste liquid containing a partially polymerized substance discharged from an equipment for producing methyl methacrylate or methacrylic acid, or both.
4. The method according to claim 1 , wherein the sticky substance or the waste liquid containing the sticky substance is a by-product in a reaction process of a petrochemical process.
5. The method according to claim 1 , wherein the solid substance having inflammability and liquid-absorptivity is in the form of a particle, flake, fiber, powder, chip, string, thread or noodle.
6. The method according to claim 1 , wherein the solid substance having inflammability and liquid-absorptivity is a fractured substance made of wood.
7. The method according to claim 1 , wherein the solid substance having inflammability and liquid-absorptivity is a cut substance made of paper.
8. The method according to claim 1 , which further comprises discharging the waste liquid containing the sticky substance from a first vessel to a second vessel, wherein after discharging said waste liquid, residue is present in said first vessel, and
mixing the solid substance having inflammability and liquid-absorptivity with the waste liquid in said second vessel.
9. The method according to claim 2 , wherein the mixture which can be handled like a solid is packed in a bag.
10. The method according to claim 8 , which comprises mixing the solid substance having inflammability and liquid-absorptivity with said residue in said first vessel.
11. The method according to claim 9 , wherein the packed mixture is burnt.
