ROTEC JSC Coating center specialists have completed the repair of the carbon dioxide absorber of Togliattiazot PJSC. The solution implemented by ROTEC will allow the company to significantly reduce the repair time of critical equipment for ammonia synthesis and increase the time between overhauls.
Coating center employees have applied composite sprayed-metal and varnish-and-paint coating to the internal surfaces of the absorber, which allows to provide long-term anti-corrosion protection of the unit against the effect of aggressive operating medium - converted gas and amines solution under high pressure. In order to do this, they have applied gas-thermal sputtering techniques which increase the protective coating adhesion and ensure the stability of its parameters. The impregnation with Hempadur 15570 composition allowed to avoid through porosity.
