Equations of State are used to determine the performance of compressors and pipeline hydraulics. These are semi-empirical models that calculate various thermodynamic and physical properties of gas mixtures for known pressures and temperatures. Isentropic enthalpy head is a critical thermodynamic parameter that is required to accurately design and performance test compressors. A novel method and test apparatus was developed to measure enthalpy rise directly using a calibrated, near isentropic compression process. This paper will discuss the modifications to this test apparatus required for measuring hydrocarbon mixtures that include corrosive gas and water vapor, the measurement methodology, and test results.

The corrected trapped equivalence ratio (TER) method for pipeline engine control allows for real-time control of exhaust emissions. While successful, this method currently lacks the ability to account for fuel reactivity effects on emissions formation. Changes in gas composition resulting in large amounts of non-methane hydrocarbons lead to higher reactivity which can result in increased NOx if otherwise unaccounted for. This work investigates the impact of composition on fundamental combustion properties and engine behavior. Findings are used to develop a correction for the existing calculation of corrected TER such that the method retains sufficient accuracy during periods of composition variability.
| Legacy reciprocating engines are critical assets to all pipeline companies. The method in which they are monitored and maintained significantly impacts each asset's overall life cycle. Combustion stabilization within this equipment has the potential to reduce green house gas (GHG) emissions, extend mean time between failure (MTBF), improve fuel economy and extend its useful life. This course is a continuation of the GMRC Introduction to Internal Combustion Engines course (available on-demand) in which deeper concepts will be explored. Attendees will be educated through presentation, virtual interaction and demonstration by use of a simulator built by the instructor. Join us in exploring a unique perspective on Combustion Stabilization in Reciprocating Engines and its Impact on Reliability. You will learn: Combustion and Fire Triangle Review What is Fuel Balancing? Importance of Fuel Balancing/Combustion Stabilization Steps to Complete Fuel Balancing Air/Fuel Ratio vs Trapped Equivalency Ratio Fuel Balancing Components (Mechanical Breakdown) Impact of Balancing/Stabilization on Emissions Balancing Utilizing a Windrock PA System Introduction to Equalization Lines Full 'Virtual' Demonstration Utilizing a Fuel Rail Simulator WHO SHOULD ATTEND All level Engineers, Analysts, Technicians, Mechanics, FSRs, Project Managers and Reliability Engineers interested in gaining a more in-depth understanding of Fuel Rail Balancing and Combustion Stabilization |

There is never enough time, people or money to blindly overhaul these units just based on run hours. That’s why our major repairs and overhauls need to be based on the unit’s true condition.The paper will mainly focus on data collected by the Equipment Analyst, and pattern interpretation of the data.
We will discuss four major components of the large reciprocating engines, and the tools needed to evaluate the Unit’s True Condition.
Combustion Engines are the heart of the Oil & Gas Industry, yielding the power to pump vital elements through pipelines across North America. This Introductory course will provide a solid foundation for individuals working on, interested in or responsible for, this equipment. Attendees will be educated through presentation, demonstration of working models and interaction with the instructor. Join us in exploring a unique perspective on Internal and External Combustion Engines designed specifically for SGA/GMRC.
