Tanks with internal roofs had to be empty, cleaned, and ventilated to install the new stilling pipes. Two pressure transmitters are installed close to the bottom of the tank and are used to calculate the density. The existing FF segments in the refinery tank farm have been verified and found feasible to accommodate the new GWR instruments in this project.

Accordingly, four tanks were selected to proceed with the field trial. The project scope was revised to mandate GWR for the project and eliminate all the complexity and constructability challenges. A nozzle size aip 6 to 8 inches was required for every tank. For tanks with no stilling piping e.

This success story had an impact not only on the Riyadh Refinery mpma, but also on Saudi Aramco standards, which have been revised to specify two-wire GWR for inventory tank gauging, as long as the vendors demonstrate a full compliance to API MPMS chapter 3.

The journey of the Saudi Aramco tank gauging project has resulted in 33.1 simple, reliable, and highly economical system for inventory tank gauging.

Measurement technology and setup: The servo gauge uses the displacement measurement principle. The GWR cable version can be extended up to 75 meters high. The figure 7 table highlights the data. So, I want to give thanks to the many people of the ISA who work on securing the future of the organization just as the original founders had.

These devices can meet the inventory and custody accuracy requirements. Three types of tanks are available: GWR is available with different process connection types and sizes. Project scope revision The successful results of piloting GWR for the inventory tank gauging application revealed a new and suitable solution for Saudi Aramco’s Riyadh Refinery project.

GWR piloting and test results A plan was set to pilot four GWR level instruments from two different manufacturers on different types of tanks with different refinery products, and to monitor the performance over one year. The instrument principle of operation is time of flight. Interested in attending an ISA Conference? ISA announces recipients of author awards. A sample of the data collected is in figure For temperature measurement and since this application is inventory, a spot temperature sensor shall be used as it is allowed by API MPMS chapter 7.

Each RTG required excavation for running new and long cables for the signals and for the external power supply, in the large tank farm area.

Also, every vendor had to provide five-point calibration of each GWR to confirm the said accuracy. The vendor selection was biding based, since the GWR instruments from both vendors demonstrated a superior and equal performance.

GWR advantages GWR technology has many advantages, which make it an attractive option for inventory tank gauging: The main challenges addressed during the design stage were: The project execution would take years, including its high cost. GWR can have an intrinsic lab accuracy between 2 mm and 3 mm, and a 25 mm installed accuracy depending on the vendor and measuring distance. A nozzle was required for the multiple spot temperature transmitter.

Fast Forward There are different level measurement options for inventory tank gauging. It was also mutually agreed with the two GWR vendors to check and confirm the following after the installation and commissioning: Founded inISA develops widely used global standards; certifies industry professionals; provides education and training; publishes books and technical articles; hosts conferences and exhibits; and provides networking and career development programs for its 40, members andcustomers around the world.

Before proceeding with the field test, the selected vendors were asked: Guided wave radar for inventory tank gauging Cut the cost, simplify the project, and expedite implementation By Fawaz AlSahan, CAP There are two internationally recognized standards covering tank gauging in atmospheric tanks.
