Dynamic Desalting Equipment  

It is an advanced technology for the dehydration and desalting of heavy, extra-heavy and light crude oil with deliverables that meet the quality required by the client.

 

Characteristics

Modular arrangements with different flow, temperature and pressure settings to process heavy, extra-heavy and light crudes.

Operation Philosophy: Suction-Process and send the Crude oil in quality.

It does not use filters, membranes and / or Electrodes for the process.

It does not use internal mechanical moving parts.

Minimum space for installation: 100,000 BPD EDDI plant requires 1000 M2.

Highly instrumented technology with automatic control of the entire process.

It replaces the Electrostatic Vessels in process for dehydration and desalting of crude oil in refineries.

Advantages

Does not use Gun-Barrels Tanks: The whole process is online.

Closed tube process allowing greater control of the operation.

Module for recovery and removal of solids in the crude oil to be processed.

Reduction and reuse of washing water for crude oil.

Minimal use of chemicals to break up the emulsion.

Minimum requirements for electrical and thermal energy.

Residence Times of crude oil in the process 1.5 Hours.

Waste Water from the process conditioned and sent under NOM-143 requirements

 

Application

The EDDI Plant allows the conditioning of crude in Marine Oil Terminals and Crude Oil Refineries.

 

The Problem

Crude from mature fields contain high levels of salinity and water. The current processes applied to condition the crude do not deliver the required quality.

 

The Solution

The EDDI Plant offers optimized conditions in pressures, temperatures and mechanical actions that configure a process that allows to condition crude oil with high levels of salinity and water and deliver processed crude with the quality according to customer requirements.

 

Economic Savings

The EDDI Plant offers economic savings by reducing the demand for electrical, thermal, water and chemical additives. Savings in installation by not requiring Gun-Barrels Tanks and by having a high plant factor eliminating unscheduled shutdowns.

 

Optimized Process for Dehydration and Desalting of Crude Oil in a safe and efficient way.

 

The Dynamic Desalting Equipment (EDDI) is designed in 3 operational stages: Stage I Lamination and Splitting of the crude oil, Stage II Mechanical Washing and Stage III Salinity Adjustment. For its design, a series of simulated tests with computer programs are applied, which emulate the basic parameters of the equipment design.

This allows modifying the flow, pressure, temperature and viscosity levels of the crude oil to be processed, in such a way that it is possible to obtain the optimum point for the operation of the process plant. The data set obtained from these tests is organized and analyzed in such a way that it is possible to establish the optimal conditions of the process plant.

The Dynamic Desalting Equipment (EEDI) has a mechanical attachment installed in the arrival head and in the Three-Phase Separator that allows the immediate reduction of speed. Likewise, a sudden change in direction which forces a large part of the suspended solids to fall to the bottom of the arrival head; thereby, ensuring that the solids recovered at the bottom of the arrival head can be mechanically removed.
