We describe Conoco’s closed-loop approach to reducing undesirable emissions through vapor recovery at some of its natural gas production facilities near Corpus Christi, Texas. In response to the U.S. Clean Air Act Amendments of 1990 (CAAA), Conoco developed a technological solution that routed emissions from the facilities to fuel scrubbers and condensers to capture usable product and hazardous...

Global greenhouse gas emissions need to peak soon and be reduced practically to zero in the second half of this century in order to not exceed the climate targets adopted in the Paris Agreement. However, there are currently numerous coal-fired power stations around the world at different stages of construction and planning that could be completed in the next decade. If all these plants are actu...

This paper presents a technical and financial analysis of several, potentially near-zero greenhouse gas emission passenger vehicles for Australian driving conditions. Conventional, series hybrid, plug-in hybrid (PHEV) and fully electric (BEV) vehicles of class B and class E sizes are considered, with their propulsive energy assumed to originate from a source that is free of net greenhouse gas e...

Background: Iran is located in the seventh rank in terms of CO2 emissions resulting from the fuel combustion in the world. Gas compressor booster stations, due to the several sources of contaminants, are causing the release of large amounts of CO2 and CH4, which will cause climate change therefore, estimating the emissions of the gases from oil and gas, different processing units are necessary....

To investigate the extent to which enteric methane (CH4) emissions from growing lambs are explained by simple body weight and diet characteristics, a 2 × 2 Latin square changeover design experiment was carried out using two sheep breeds and two fresh pasture types. Weaned lambs of two contrasting breed types were used: Welsh Mountain (WM, a small, hardy hill breed) and Welsh Mule × Texel (TexX,...

To achieve the goals of low carbon emission and neutrality, some urgent challenges include development utilization low-carbon or zero-carbon internal combustion engine fuels. Hydrogen, as a clean, efficient, sustainable fuel, has potential to meet abovementioned challenges. Thereby, hydrogen engines have been attracting attention because their zero emissions, high thermal efficiency, reliabilit...

The University of Denver's remote sensor (FEAT) was used for an on-road motor vehicle carbon monoxide (CO) and hydrocarbon (HC) emissions survey in Australia during April and May, 1992. Twelve locations in Melbourne area were selected as the survey sites. Most of these locations were the on or off ramp of a freeway or a two way road divided by a solid or painted traffic island. The raw data fro...

The nonrivalrous property holds when use of a unit of the good by one consumer does not preclude or diminish the benefit from another consumer using the same unit of the good. Thus there is jointness in consumption of the good— one unit of the good produced generates multiple units of consumption. Nonrivalrous implies that the opportunity cost of the marginal user is zero. Some classic examples...
