The article deals with of a hydrogen pressure vessel suitable for high pressure of approximately 75 MPa. One of the goals is to design a vessel from materials whose strength will meet mechanical requirements a calculated in both analytical and numerical ways. Another objective is the simulation of the design the pressure vessel with regard to safety and weight requirements.

Simulation and testing technology of sintering flue gas recirculation, under Arcelor Mittal S.A.Galati proved its superiority compared to conventional sintering technology by: lower specific consumption of coke by approx. 10 to 15%; lower costs agglomeration; reduction of pollution due to: decrease of specific volume of exhaust gas to the basket by 45 - 50% ;decrease in the emission of SOx to basket approx. 55%; lowering NOx emissions from basket approx. 50%; CO2 emissions drop to approx basket. 20%; retention lay...
