The sources of formation of inorganic and organic contaminations in industrially piped and stored vinyl chloride monomer.
II. The effect of temperature, pressure, adsorption, metod of piping, and construction material on the physico-chemical transformations in vinyl chloride.
The sources of formation of inorganic and organic contaminations in industrially piped and stored vinyl chloride (VC) monomer have been presented in general. The effect of temperature, pressure and adsorption, the role of surface tension in the processes of physico-chemical transformations in VC, as well as the effect of the handling procedure and type of construction material used for pipelines and tanks have been discussed. A particular attention has been paid to the composition of the constructional steel used and to the presence in it of non-metallic inclusions. The requirements to be met by the installation for piping and storing VC monomer have been presented and an essential role of a careful preliminary preparation of this plant (purification, etching, passivation) before putting it into operation has been pointed out.
