Optimizing Gas Turbine Fuel Gas Supply

The mission of this blog has always been to bring the experts around Emerson to you. Many of these folks also share their expertise in our Emerson Exchange 365 global user community and with LinkedIn posts. I’ll highlight an example I saw today.

Emerson's Rossella Mimmi

Emerson’s Rossella Mimmi published a post, Gas Conditioning: Why, When and How. In it, she opens:

Natural Gas has become the desired fuel for gas turbines used in modern power plants. Gas turbines are extremely sensitive to contaminants carry-over into the combustors, thus requires fuel gas to be treated to high level of purity for total protection and optimal operation. Gas Conditioning skids are used to clean and treat the gas to achieve the best results and ensure the highest turbine performance.

These gas conditioning skids perform the functions of removing contaminants entrained in the gas stream, superheating the gas stream above the hydrocarbon dew point, reducing pressure and maintaining tight pressure control, measuring the gas flow rate, and odorizing the gas so that it can be smelled in case of leaks.

Real-Time Corrosion and Erosion Monitoring

The biennial Petrotech conference in New Delhi, India is for oil & gas industry experts to exchange views and share knowledge, expertise and experiences. And given the pricing dynamics and changes in global supply levels and supply chains, there is much to discuss and share.

At the last conference this past December, Emerson’s Rajesh Nogaja presented Online Real-time Corrosion/ Erosion Monitoring Systems Ensure Top Quartile Business Performance. Here is an excerpt from the abstract of this presentation:

Emerson's Rajesh Nogaja

Corrosion and erosion is a major challenge for the Oil and Gas industry, Pipelines, Refineries and Petrochemical plants. Online Realtime Corrosion/Erosion Monitoring Systems helps the customer increase Profitability, Optimise Costs and Enhance Overall safety. Areas of Top Quartile Business Performance Improvements achieved are:

  1. Increased Production rates and margins through Use of High TAN Opportunity Crudes
  2. Sustainability of Infrastructure and Assets for longer periods, delayed Turnarounds
  3. Early detection of Possible Piping and Asset Failures, improving safety and reliability

Rajesh discussed both inline/intrusive monitoring systems and non-intrusive ones. Roxar coupons are installed in pipes and vessels for some time period. Loss rate is determined by the coupon weight loss but can be affected by deposits, bacteria and corrosion. Roxar probes have very high sensitivity and ultrafast responses to provide efficient process corrosion/erosion management through the use of inhibitors and controlling production rates.

Increasing Maintenance Efficiency with Handheld Instrumentation Communicators

Those with smart instrumentation know that installation, configuration and maintenance activities often require the plant technicians to carry multiple tools such as external power supplies or loop simulators in addition to the handheld instrumentation communicator device. Properly functioning instrumentation helps the operations staff and automation system control strategies manage the process more safely, reliably and efficiently.

In this 3:29 YouTube video, AMS Trex: Improving Maintenance, Monsanto’s Joel Holmes describes how Power the Loop technology in the AMS Trex Device Communicator has had a positive impact on their organization’s maintenance practices.

Non-Intrusive Corrosion and Erosion Monitoring

The integrity of process piping is paramount to safe operations. Corrosion and erosion monitoring, especially for processes with challenging fluids, play an important role.

This short 2:10 YouTube video, Permasense ET210 Integrity Monitoring System, shows how piping erosion and corrosion can be monitored with pipe wall thickness measurements with non-intrusive wireless sensors strapped to the pipe. These sensors are yet more building blocks in the Industrial Internet of Things (IIoT) to monitor and provide early warning to improve overall operations. Continue Reading

Under Pressure: New Developments in High-Pressure Chemical Injections

Emerson's Travis Stone

Over in LinkedIn, Emerson’s Travis Stone has posted part 3, Under Pressure: Emerson Announces a New Development in High Pressure Chemical Injections, in our series on improving chemical injection processes.

These posts highlight the issues associated with underinjecting chemicals and the excessive costs associated with over injection. Optimimum rates of injection help assure piping integrity by inhibiting deposits and corrosion.

Here is an excerpt from the opening of his post:

A lot of people have concerns about the future of oil and gas, and about how fossil fuels will contribute to the energy mix in the coming years. Considering the prolonged oil price downturn since 2014, along with budget restrictions on new projects, and the potential for recent political volatility to affect regulations, these concerns seem justified.
