Procedure for controlling inestibilidad in ethane Separation column in Fluid Catalytic Cracking units and in delayed coking units

摘要

In the present application describes a procedure for the control of unstable operation of a Separation column of Ethane (13) in the area of gas recovery in Fluid Catalytic Cracking units and in delayed coking units.The purpose of this is achieved by means of a procedure that includes the Operational step of intervening in the ethane Separation column (13) to occur in the same instability, proceeding to an adaptation of Material Balance of water, so that the excess water from the C Orriente LOAD SUPPLY (9) is extracted as an azeotrope.The intervention is performed by introducing the load current feed (9) of this column separation of Ethane (13) of a volume fraction (18) from a Hydrocarbon Stream and / or an External Power to the unit, which can be selected between HID Rocarburos Dry and Oil with Low Water content.
