Smart Wireless solutions from Emerson Process Management are making new measurements at three of Tecpetrol’s natural-gas compression and delivery facilities in Argentina.

These solutions are said to be improving profitability and environmental compliance at Tecpetrol.

The company opted for the Smart Wireless solutions as it quickly needed to collect real-time gas flow data.

The continuous data helps it track gas venting, comply with environmental regulations, measure gas sold to third parties and perform AGA 3 calculations needed for the economic balancing of its three facilities.

‘The wireless applications saved us a total of USD34,000 [GBP20,500] in installation costs compared to installing a wired solution – a 27 per cent saving,’ said Odin Fernandez, automation and energy head at Tecpetrol.

Ten each of Emerson’s Rosemount wireless-pressure, differential-pressure and temperature transmitters are installed in the orifice plates at gas well heads across the facilities.

The devices transmit data every 15 seconds to Smart Wireless gateways installed at each facility that forward data to their DeltaV digital automation system.

The wireless network monitors the gas balance of the treatment plants including dew point, primary separation, compression stages contracted, consumption and plant venting.

Some of the data points tapped had never been monitored before.

Other points had been checked manually by staff reading local gauges.

‘We needed to closely watch our gas balance because excessive gas venting can affect our company’s bottom line through lost product and because our gas venting levels must comply with environmental regulations,’ added Fernandez.

Installing the equipment took one day; the devices have performed well with no data loss since commissioning, despite these areas being heavily congested with pipes and equipment.

Smart Wireless has eliminated the need for clipboard rounds.

Fernandez continued: ‘One of the advantages in using this equipment is that our process is very variable and involves piping modifications, compressor layouts and primary separation, among others.

‘We can move the measurement points when we need to and do not depend on pipes, cabling, etc,’ he said.

Tecpetrol plans to expand its Smart Wireless use to include test measurements during well drilling.

In addition to Smart Wireless solutions, Emerson offers a range of wireless field instrumentation and plant operations equipment, including Fisher position monitors, Rosemount Analytical and Machinery Health Management devices, native wireless interface-to-AMS Suite predictive maintenance software and Smartstart services.
