Project scope revision The successful results of piloting GWR for the inventory ,pms gauging application revealed a new and suitable solution for Saudi Aramco’s Riyadh Refinery project. Moreover, it provides a versatile solution, which allows different hardware and communication protocols to mms used and allows DCS as a platform for software inventory calculations.

New cabinets, hardware, and software installations in the process interface buildings were required, which could mean expansion of existing buildings or construction of new ones.

HTG Project initial scope and challenges One recent tank gauging project at Saudi Aramco Company was scoped to install radar tank gauging with multiple points of temperature measurement on 42 tanks for crude and refined products. Manual gauging uses either the innage from the top flange to the bottom of chzpter tank or ullage from the top flange to the top liquid layer method to measure the total liquid level inside the tank.

Choose from one category below to get involved now! The spring provides constant tension, which balances the float on the liquid level. The GWR cable version can be extended up to 75 meters high.

Float and tape gauge This solution uses a float attached to a spring via a perforated tape. The project scope was revised to mandate GWR for the project and eliminate all the complexity and constructability challenges. Radar tank gauging Radar tank gauging RTG is the most common solution for tank gauging. GWR has different and open communication protocols, such as analog mA, Foundation fieldbus, and wireless.

Cost, schedule, and other challenges affect the final technology selection. Reader Feedback We want to hear from you! GWR is available with different process connection types and sizes. The Saudi Aramco Riyadh Refinery revised the project scope for implementing inventory tank gauging on 42 tanks, and ended up with a simple, cost-effective, and fast project implementation.

Training Classes See All. The project’s final scope of work was revised as follows: The perforated tape is connected to a mechanical counter assembly. ISA and Honeywell to co-host free web seminar on ,pms for gas metering and data management. GWR technology has many advantages, which make it an attractive option for inventory tank gauging:. GWR shall be used for inventory tank gauging for the Riyadh Chaper project.

InTech Magazine Web Exclusive: GWR technology was tested in Saudi Aramco for inventory tank gauging with successful results. GWR is “plug and play” and a maintenance-friendly technology. Three storage tank types. Accordingly, four tanks were selected to proceed with the field trial.

Over one year, the refinery operation team conducted manual dipping to check the reading accuracy of the installed GWR instruments.

Guided wave radar for inventory tank gauging

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 existing FF segments in the refinery tank farm have been verified and found feasible to accommodate the new GWR instruments in this project. 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.

Also, every vendor had to provide five-point calibration of each GWR to confirm the said accuracy.

Special Section: Guided wave radar for inventory tank gauging – ISA

A small displacer weight on a measuring wire from a drum is accurately positioned and balanced in the liquid medium using a servomotor. The instrument principle of operation is time of flight. ISA to provide end-user perspective in new international smart manufacturing collaboration. So, I want to give thanks to the many people of chzpter ISA who work on securing the future of the organization just as the mpmz founders had. A pressure transmitter shall be installed at the bottom of each tank to assist in mass calculations.

The servo gauge uses the displacement measurement principle. Servo gauge The servo gauge uses the displacement measurement principle. ISA members have access to dozens of unique benefits.

A third transmitter measures the vapor pressure at the top of the tank to increase the accuracy. This step has eliminated proprietary hardware and software for the tank inventory calculations. These devices can meet the inventory and custody accuracy requirements.

GWR can be installed while the atmospheric storage tank is in service. Both vendors provided the confirmation and data required. Tank cgapter parameters and calculations in DCS.

A GWR instrument can provide both total hydrocarbon level and water interface level. Over this period, the operation team conducted frequent manual gauging three times per test to check the installed accuracy of the GWR.

After commissioning, the echo curve was collected for each transmitter to confirm a strong echo for each GWR, with chater loss of signal and no interference figures 10 and This success story had an impact not only on the Riyadh Refinery project, 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 GWR success story has also opened another opportunity for using two-wire noncontact radar for inventory tank gauging, as these noncontact radar instruments have the capability to meet the requirements of API MPMS chapter 3. Before proceeding with the field test, the selected vendors were asked: Fast Forward There are different level measurement options for inventory tank gauging. Three types of tanks are available: The pai 7 table highlights the data.
