Refractories for HYDROCARBON Industry------ Passary Minerals Ltd., Rourkela.------The Hydrocarbon Industry poses the toughest challenge to

a refractory-maker. High physical and thermal stability, absolute inertness to the attack of gases as well as inertness to chemical attack are the benchmarks for refractories applied in this industry.

PASSARY MINERALS LTD., Rourkela, India, a pioneering company in producing technology-intensive and technologically challenging refractories, offers a basket of refractory products for the Hydrocarbon sector.

The slides to follow enumerate the application wise / area wise products that PASMIN suggests for the Hydrocarbon industry.
