Data improvements at natural gas facilities

28 November 2009

Rosemount wireless transmitters have improved data delivery at three Tecpetrol natural gas compression facilities in Argentina. The sites measure venting, deliver gas data for AGA 3 calculations to balance plants, and data for fiscal accounting of sold gas.

Smart Wireless solutions are improving profitability and environmental compliance and are thought to be the most cost-effective solution for the company, which quickly needed to collect real-time gas flow data. The reliable, continuous data helps the company track gas venting, comply with environmental regulations, measure gas sold to third parties, and perform AGA 3 calculations needed for economic balancing of its three facilities.

"The wireless applications saved us a total of $34,000 in installation costs compared to installing a wired solution, a 27 per cent saving," said Odin Fernández, automation and energy head, Tecpetrol. "We preferred Smart Wireless because it’s a secure, robust, self-organising network. It’s reliable and easy to install, expand, and use."

Ten each of Emerson Process Management’s Rosemount wireless pressure, DP, and temperature, transmitters are installed in the orifice plates at gas well heads across these facilities. The devices transmit data every 15 seconds to Smart Wireless Gateways installed at each facility that forward data to the company’s 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.
