<p>In the staged grid assembly, the gas and liquid mixture flows first through a lower secondary flow distribution grid plate (30) into an interim zone (35), and then flows upwardly through an upper primary flow distribution grid plate (12) into the reactor ebullated bed (25). The staged grid assembly contains an upper primary grid plate containing multiple flow tubes (16) covered by bubble caps (18), and a lower secondary grid plate containing multiple flow tubes (32). The assembly enables the primary grid to provide a more uniform distribution of gas and liquid flow upwardly into the ebullated bed across the entire cross- sectional area of the reactor, and thereby provides improved operation of the ebullated catalyst bed reactor. <IMAGE></p> |
