In the petrochemical plant in Algeria, the Depropanizer Feed Pump and the Deethanizer Feed Pump are the core equipment of the Natural Gas Liquid Fractionation Unit (NGL Fractionation Unit). These pumps are responsible for transporting natural gas liquids (NGL) from the pretreatment system to the Deethanizer (Deethanizer T-201) and Depropanizer (Depropanizer T-301) for fine fractionation. In this plant, the bottom product of the Deethanizer will be sent to the Depropanizer, while the bottom product of the Depropanizer will enter the Debutanizer (Debutanizer T-401) to finally produce high-purity liquefied petroleum gas (LPG) products.
