ABSTRACT:
Improved trough-type liquid distributors and redistributors for use in vapor-liquid contact columns wherein uniform distribution of downflowing liquid is achieved by employing orifices in the sides of troughs, said orifices being sized such that they stay submerged. Better distribution is obtained when the orifices are used with adjacent vertical drip rods to which the liquid can adhere and follow downwardly by gravity flow. The invention allows good distribution at very low flow rates, e.g. less than 0.8 gallons/minute/square foot.
