Aqueous cleaning composition and method |
摘要 |
An aqueous cleaning composition for removing paraffin, asphaltene, and scale deposits or plugs from a hydrocarbon system. The aqueous cleaning composition is formed of a cleaning composition and an aqueous liquid. The cleaning composition contains about 21-33% of a silicate, about 20-35% of a peroxygen, about 3-15% of a phosphate, about 15-40% of a carbonate or bicarbonate, about 1-10% of a chelating agent, about 1-5.5% of a surfactant combination. In one embodiment, the surfactant combination includes a surfactant polymer mixture containing a block polymer and a reverse polymer, and a wetting agent containing a sulfonated material or an ethoxylated alcohol. |

1. A cleaning composition for removing a deposit from a hydrocarbon system, the cleaning composition comprising:
about 21% to about 33% of sodium metasilicate; about 20% to about 35% of sodium percarbonate; about 3% to about 15% of sodium tripolyphosphate; about 15% to about 40% of sodium carbonate; about 1% to about 10% of ethylene diamine tetra acidic tetra sodium salt; about 0.4% to about 1.5% of a branched alcohol ethoxy phosphate; about 0.6% to about 2% of a surfactant polymer mixture which is a polyethylene glycol stearate and an equal amount of an ethylene oxide/propylene oxide block polymer and an ethylene oxide/propylene oxide reverse polymer, mixed with a polyethylene glycol stearate; and about 0.5% to about 2% of a wetting agent which is a nonionic ethoxylated alcohol. |
