Performance, Efficiency, and Emissions Characterization of Reciprocating Internal Combustion Engines Fueled with Hydrogen/Natural Gas Blends

Description: Hydrogen is an attractive fuel source not only because it is abundant and renewable but also because it produces almost zero regulated emissions. Internal combustion engines fueled by compressed natural gas (CNG) are operated throughout a variety of industries in a number of mobile and stationary applications. While CNG engines offer many advantages over conventional gasoline and diesel combustion engines, CNG engine performance can be substantially improved in the lean operating region. Lean o… more

Cost-Effective Reciprocating Engine Emissions Control and Monitoring for E&P Field and Gathering Engines: Report 5

Description: During the fifth reporting period, the main goal for the team was to focus on collecting data to develop Oxygen Sensor Recording System (OSRS) parametric relationships for several rich-burn engines. An air/fuel ratio controller was intergraded with an O{sub 2} sensor. With the use of an Alternative Continuous Emissions Monitoring System (ACEMS) provided by Eastern Municipal Water District (EMWD), the performance will be observed during normal operation.

Cost-Effective Reciprocating Engine Emissions Control and Monitoring for E&P Field and Gathering Engines: Report 4

Description: During the fourth reporting period, the project team investigated the Non-Selective Catalytic Reduction technologies that are in use on rich-burn four-stroke cycle engines. Several engines were instrumented and data collected to obtain a rich set of engine emissions and performance data. During the data collection, the performance of the catalyst under a variety of operating conditions was measured. This information will be necessary to specify a set of sensors that can then be used to reliably… more

Cost-Effective Reciprocating Engine Emissions Control and Monitoring for E&P Field and Gathering Engines: Report 14

Description: Continuing work in controlled testing uses a one cylinder Ajax DP-115 (a 13.25 in bore x 16 in stroke, 360 rpm engine) to assess a sequential analysis and evaluation of a series of engine upgrades. As with most of the engines used in the natural gas industry, the Ajax engine is a mature engine with widespread usage throughout the gas gathering industry. The end point is an assessment of these technologies that assigns a cost per unit reduction in NOX emissions. Technologies including one pre-co… more

Virtual Pipeline System Testbed to Optimize the U.S. Natural Gas Transmission Pipeline System

Description: The goal of this project is to develop a Virtual Pipeline System Testbed (VPST) for natural gas transmission. This study uses a fully implicit finite difference method to analyze transient, nonisothermal compressible gas flow through a gas pipeline system. The inertia term of the momentum equation is included in the analysis. The testbed simulate compressor stations, the pipe that connects these compressor stations, the supply sources, and the end-user demand markets. The compressor station is … more
