Method for controlling instability in the tower deetanizadora in units of cracking catalu00ectico fluid and in delayed coking units

摘要

The present invention reported on a method to perform the control of instability of operation in a tower deetanizadora (13) in the area of recovery of gas and fluid catalytic cracking units in units of delayed coking unit.The objective of this invention is achieved by a method which includes the step of intervening in the tower deetanizadora (13) to occur in the same instability by an adaptation of the sheet material of the water, so that the excess water from the load current supply (9) it is only removed as azeu00f3tropo.The intervention is done by means of introduction in the load current supply (9) of this tower deetanizadora (13) of a fraction of volume (18) of a chain hydrocarbon and sym or an external current to the unit, which can be chosen from hydrocarbons, dry and hidrocarbon Ethos with low water content.
