CHEMICAL TREATMENT METHOD FOR INNER SURFACE OF HYDROCARBON PYROLYSIS REACTOR |
| 摘要 |
FIELD: oil and gas industry.SUBSTANCE: before start-up of the reactor its surface is treated by flushing with vapour-liquid acid solution at temperature of 100-200°C and further neutralisation with aqueous base solution 0.0001-1 wt %. Neutralisation is ceased when flow medium reaches value of pH 8-9.5 at the reactor output.EFFECT: reduced coke formation at inner surface of the reactor.4 cl, 3 tbl, 12 ex |
