The challenge

The objective of the project was to provide Pemex with the capability to validate the volume of gas that was flowing from their pipes to the customer, in real time. The two main challenges faced at the Pemex OASyS SCADA control center were firstly, the replacement of obsolete equipment with the latest, most efficient technology, and secondly, an upgrade to the flow computer without changing registers for local DCS and SCADA screens.

SCADA Industrial’s extensive experience, competitive costs, and familiarity with the existing equipment and the SCADAPack 350 already installed, made them the natural choice to implement this project. .

The solution

SCADA Industrial implemented SCADAPack 350 flowcomputer settings using RealFlo 6.84 with the PemexModbus. Calculations were validated onsite, using typical flow conditions and verifying real-time data remotely from the Pemex’s SCADA control center in Mexico City

In order to comply with AGA-7 and AGA-8 recommendationsand to validate the flow computer program loaded in theSCADAPack, Pemex and SCADA Industrial measurementengineers ran various volume and energy tests comparingstandard natural gas flow calculation software such asFlowCheck 3.1 and GMAS in the OASyS package.

Event, alarm, and historical data from the SCADAPack 350were configured with Realflo 6.84 using the Pemex Modbusprotocol.

All transmitters and pulse output signals were checkedand calibration records reviewed by the local stationpersonnel. Records polled also included real-time data forthe solar panel, battery, and UPS data concentrated in theSCADAPack. Pemex requires the flow control valve statusand PID settings to be included in a third phase of thisproject, which will be completed by the end of Q3 2016.

GoalDeliver a sustainable and efficient natural gas measurement site.

StorySchneider Electric’s SI Alliance partner, SCADA Industrial, provides an innovative solution to Mexican gas supply company to accurately measure gas flow and optimally run their systems.

SolutionUtilize the flexibility and reliability of the SCADAPack 350 and Realflo software to deliver complex flow calculations to the gas measurement control site.

The Benefits

Easier configuration and historical reportingThe gas management company has found it easier and faster to configure each flow computer and download historical reports at each measurement station. They have reported that the site start-up time has gone from up to several days, to just four hours. This can be translated into labor savings of more than 50%

Reliable equipmentThe gas management company can now depend on the new flow computers with SCADAPack for a life cycle that is twice as long as it was previously.

Seamless equipment replacementReplacing older flow computers and installing newer SCADAPacks has been a simple task and it’s now taking 60% less time to replace and configure at new sites around the country

Less maintenance and increased operation efficiencyTechnicians at the gas management company spend less time troubleshooting gas flow computer issues and can focus on serving their natural gas customers.
