Abstract
PURPOSE:To provide the titled surface-treating agent containing at least one kind of compound selected from inorganic acid, organic acid and organic acid salts as a main component and effective in safely and easily suppressing the adhesion and deposition of polymer without changing the operation condition. CONSTITUTION:The objective surface-treating agent for the treatment of the inner surface of an olefin-production apparatus is produced by using at least one kind of compound selected from inorganic acid (e.g. hydrochloric acid or sulfuric acid), organic acid (e.g. oxalic acid or acetic acid) and organic acid salt (especially preferably Na salt or K salt) as a main component. The component is preferably used in combination with one or more kinds of additives selected from corrosion-protection agent, reducing agent and penetrant. The agent is effective in preventing and suppressing the troubles caused by the adhesion and deposition of polymers to the inner surface of a production apparatus for olefins, especially a fractionating column. The apparatus is filled with an aqueous solution of the treating agent having a concentration of 0.5-3wt.% in the suspension of the operation. The surface treatment can be easily performed and the normal operation of the apparatus can be carried out after discharging the treating agent from the apparatus.
