APPARATUS FOR CONTACTING GAS,LIQUID AND SOLID PARTICLES

摘要

Process for contacting gas, liquid and solid particles in a reactor 1 comprising a) introducing gas through inlet 2 and liquid through inlet 3 into the lower part of the reactor 1 and introducing solid particles into the upper part of the reactor 1 through inlet 7; b) passing gas and liquid upwardly through a number of contact zones 10 arranged one above the other and having a thickness of between 0.5 cm and 20 cm and separated from each other by screens 11 provided with a large number of apertures with an area per aperture of between 0.05 cm<2> and 5 cm<2>, the ratio between the sum of the areas of the apertures and the total area of a screen 11 lying between 0.4 and 0.8, and allowing solid particles to pass downwardly through the contact zones 10; and c) removing gas and liquid through outlets 4 and 8 from the upper part of the reactor 1 and removing solid particles from the lower part of the reactor 1 through outlet 5. n
