The paper briefly reviews the technology, gas turbine versus high speed electric drive, which represents two very different solutions for natural gas pipeline or storage compressor drive applications. The technical and economic merits of the competing drive systems have to be considered for each individual project. Traditionally, gas turbines have been the prime drivers for compressor trains, especially in Europe whereas in North America gas engine driven reciprocating compressors are also very common. With the liberalization of the electric power market and tighter environmental restrictions regarding local emissions, high frequency electric motor drivers became a competitive alternative profiting by decreased costs for the electricity infrastructure and the power supply, thus lowering the investment and operational costs. Gas turbines in compliance with the latest emission regulations will maintain their predominant role in natural gas pipeline and storage applications, especially in non-residential and remote areas.

Natural Gas Pipeline

Hydrogen, reacting with oxygen, is a very energetic, non-polluting fuel. Can it be used as a fuel for gas turbines? Two successful and significant examples of its use are reviewed. Surplus renewable electrical energy from solar and wind could be used for electrolysis of water to produce hydrogen to power gas turbine power plants. Serving as a means of energy storage, the hydrogen could be kept in caverns. It could also be added directly to natural gas pipeline systems serving gas turbine power plants, thus reducing greenhouse gas production.

Software for monitoring and evaluating the performance of gas turbines is being developed under the auspices of Gas Research Institute (GRI). Reference [1] provides an overview of the GRI project. This paper describes the PEGASUS software and monitoring system. PEGASUS is an acronym for Performance Evaluation of GAS Users Systems. Field test results, on multi-shaft turbines used in the gas pipeline industry, have demonstrated the potential of the software. The software and instrumentation, can help identify maintenance and upgrade actions to improve performance.

Flux Leakage

TransCanada was faced with a significant challenge to inspect a 941 km NPS 48 pipeline. The options for the inline inspection (ILI) were multiple segments which would cause an increased cost with new pigging facilities required and a delay to the ILI schedule or attempt to pig the longest natural gas pipeline section in North America. The extraordinary proposal would require a massive 48″ combination Magnetic Flux Leakage (MFL) tool to traverse a high-speed gas pipeline 941km from Burstall, Saskatchewan to Ile des Chenes, Manitoba, Canada. Given the alternative of the installation of 3 additional launcher and receiver stations and the risk to overall project schedule from extended inspection operations, TransCanada took the bold decision to perform an MFL inspection in a single pass. However, as expected, this option created a new set of challenges to guarantee first run success in one of the harshest environments for an ILI tool and in a line where the cleanliness condition was unknown. This last factor, was a critical concern as the volumes of debris that could be collected with the highly aggressive MFL tool brushes, could easily and very quickly have led to very significant debris build up during inspection that at best would likely cause degraded data leading to an unwanted re-run and at worst the possibility of a stuck pig and subsequent retrieval program. From a project perspective either occurance was considered to be mission critical — if either occurred there was no easy solution to collecting the much needed condition data of the pipeline. In July 2017, a successful VECTRA HD GEMINI inspection was completed. This paper discusses the main program risks, mitigation steps taken over and above a standard ILI run. Key considerations and actions taken relating to additional engineering and tool modifications to various components of the inspection vehicle itself will be discussed. Lastly, insight will be given into an extensive smart cleaning program developed with the ILI vendor, using a combination of mechanical cleaning associated and debris level assessment, specifically designed and tailored for the project to ensure that the pipeline was both ready for ILI and that cleaning had reached optimum for ILI so that full, high quality MFL data would be collected the first time.

Carbon Dioxide Co2

The deployment of small gas turbines at landfills and wastewater treatment plants is attractive due to the availability of waste fuel gases generated at these sites and the need for onsite power and/or heat. The fuel gases produced by these applications typically contain 35 to 75% of the heating value of natural gas and contain methane (CH4) diluted primarily with carbon dioxide (CO2) and sometimes nitrogen (N2). Demonstrations of 30 to 250 kW gas turbines operating on these waste fuels are underway, but little detailed information on the systematic effect of the gas composition on performance is available. Growth in the use of small gas turbines for these applications will likely require that they meet increasingly stringent emission regulations, creating a need to better understand and to further optimize emissions performance for these gases. The current study characterizes a modified commercial natural gas fired 60 kW gas turbine operated on simluated gases of specified composition and establishes a quantitative relationship between fuel composition, engine load, and emissions performance. The results can be used to determine the expected impact of gas composition on emissions performance.

For the conveyance and storage of natural gas, compressor stations are required where the installed power output varies mostly between 1 MW and 20 MW. The noise control measures involved to meet the environmental noise emission regulations in Europe will be presented. The most economical noise control techniques are described particularly for the intake and exhaust systems of gas turbines, the housing of such engines, and peripheral sound sources like gas coolers, oil coolers, and aboveground piping.

Transmission Pipeline

A software package which optimizes natural gas pipeline operation for minimum fuel consumption is in use on a commercial transmission pipeline. This Optimization Program has resulted in pipeline fuel savings in daily pipeline operation. In addition, the effect of a new compressor/turbine unit on the pipeline system as a whole can be accurately and easily quantified through use of the Optimization Program before the unit is even installed. The results from one turbine replacement study showed the total system fuel consumption and operating hours predicted for each unit were not directly related to a high turbine efficiency. This paper describes the simulation techniques used for the gas turbine and compressor modeling. The methodology behind the system-wide optimization is also provided, along with a detailed discussion of the program application to gas turbine and compressor replacement studies.

Since the early 1960’s, the use of aero-derivative and industrial gas turbines on TransCanada’s natural gas transmission system has been the norm, with a total of 245 units installed to date. In 1996 and 1997 the company installed six high-speed, 30.6 MW, variable speed, electric drive systems. In the same time period eight aero-derivative gas turbines of similar power, with Dry Low Emissions, were installed. After an elapse of three years running time we now have enough data to compare the performance of the two different compressor drivers. A comparison of the performance of the two prime movers is made in a number of different ways. Operation and maintenance costs of the two different systems are considered, including the fuel costs of the natural gas and electricity, from three different Canadian electric power utilities.
