摘要： PURPOSE:To form O/W type emulsion having stability and to promote remarkable viscocity reduction by making the motive power of a stirrer large successively and adding water to heavy oil, mixing and stirring the mixture stepwise. CONSTITUTION:In production of emulsion in pipeline transport and marine transport, etc., of heavy oil, plural pieces of stirrers wherein the stirring conditions are changed are provided and a stirrer having small motive power is used as an initial stirrer and stirring motive power is made large than the previous stirrer as next stirrer and successively the stirrer having large motive power is used. When a mixture of heavy oil and water is slowly stirred, firstly heavy oil partially sheared and emulsion having large particle diameter is formed and thereafter this emulsified material is subjected to small granulation. In such a way, uniform O/W type emulsion is formed and emulsion high in stability can continuously be produced in large quantities.

摘要： PURPOSE:To enable a leak portion of hydrogen sulfide to be easily specified by dissolving and diffusing a pigment, a surface-active agent, an organic solvent, and ferric chloride to a dilution liquid solution of hydrochloric acid or sulfuric acid and adding p-aminodimethylaniline dihydrochloride, etc., to it. CONSTITUTION:A pigment such as TiO2, SiO2, and CaCO3, a surface-active agent, an organic solvent, and ferric chloride are dissolved and diffused by pure water and a small amount of hydrochloric acid or sulfuric acid is added to it. Furthermore, p-aminodimethylaniline dihydrochloride or chlorodimethyl-p- pheynylene dihyrochloride is added to obtain a white slurry liquid. This solvent is coated and sprayed to a welding portion and a connection portion of a plant, a machine, a device, etc., which handle hydrogen sulfide. When a lead of hydrogen sulfide is detected, p-aminodimethylaniline-2 hydrochloride becomes blue under presence of ferric chloride and this is highlighted by white color of the pigment. For example, a coated surface 8 of a detection agent is formed at a welded portion 7 where a piping 6 which allows a gas containing hydrogen sulfide to flow is joined to detect the leak.
