The present invention relates to a chimney for a distributor which includes (i) a cylinder with open upper side and underside, and (ii) a cone-shaped material at the bottom which has a flat tip and is installed separated from the underside of the cylinder, wherein a gas inlet is built on the upper side of the cylinder, and on the side of the cylinder, an upper orifice and lower orifice are respectively built. The chimney of the present invention and the distributor maximize distribution efficiency, and thus can minimize the layers of grading material installed between the distributor and catalyst layers in the hydrotreater reactor; and accordingly, can reduce the size of the hydrotreater reactor, thereby minimizing manufacturing costs. |
