EZER provides a wide range of Process Basic Design for the expansion of Refinery plant capacity and/or the energy saving for the sake of maximizing benefit of clients.

Below content is to introduce the project according to refinery
 
CDU Revamping Basic Design
Needs
The needs of client (H-Oil Bank) were as follows
  • Maximum capacity without crude heater modification
  • Method for assuring safety without flare system modification
  • Change of operation mode compared with the existing design
  • For solving the small space issue, the plate type HX application
  • The solution for caused trouble from plate type HX operation because heat is transferred between pump-around and heat train
Problems
Some problems came out as we tried to meet client's needs
  • Space limitation
  • Opposition by production department to plate type HX application not used in general
Solutions
In order to solve the problems and to meet the client's needs, EZER performed the following works as below
  • Tuning of simulation modeling based upon the existing data
  • Column internal loading analysis, heat train rearrangement with pinch technology, optimum operation mode changing for energy saving and prediction of trouble from plate type HX application should be totally analyzed in order to prepare for solution by each case
  • No changing safety system except adding safety valves
  • 67% of capacity upgrading compared with design capacity without crude heater modification
  • Maximization of energy efficiency through HX rearrangement and addition of plate type HX
  • Modifying crude tower internal
  • Adjusting vapor feeding tray of ATM tower using flash drum
  • Unifying the different safety analysis basis among companies
