产品介绍 ( Product Presentation )

There id the liquified gas on the tower top,there ie the stable light hydrocarbon on the tower bottom,the tower is equipped with reboiler of its bottom.Going throuth light components rising by reboiler’s heat connect with heavy components dropping on the tray,will get the result of mass transfer and heat transfer.The gas-liquid concentration of debutanizer  is changed on ladder shape from tower bottom to tower top.The main function of debutanizer is that carrying throuth incision and separation of“mixed hydrocarbon” that comes from debutanizer,producing“LPG”and “stable light hydrocarbon”, its heat source supply is provided by heat conduction oil by means of reboiler of tower bottom .The back flow on tower top of debutanizer employs the light liquied gas.

Natural gas debutanizer is a part of Ⅱ category of vessel.
