Passivation agent ARBAPRIME is designed for high-temperature processes such as visbreaking and thermal cracking. It serves as a primer for the preliminary formation of a passive film on the surface of hot equipment before the use of antifoulant reagents such as ARBACOKE and ARBADISP. By forming a thin, extremely thermo-resistant phosphate film, ARBAPRIME helps the metal surface remain clean and passive for an extended period, thus allowing for a longer turnaround time.
APPLICATION
- To create an effective passive film, the product must be dosed into a hot stream immediately after starting up the equipment and entering the operating mode.
- Typical additive dosage rates of ARBAPRIME from 20 to 50 g/t of high-temperature flow, depending on the type of material design of the equipment (type of steel and content of chromium and other alloying elements in it).
- The best effect from using the ARBAPRIME primer is achieved with the subsequent use of a combination of antifoulants - polymerisation inhibitor ARBADISP with coke formation inhibitor ARBACOKE.
