The Effect of Allowance Allocation on the Cost of Carbon Emission Trading [PDF]

We investigate the cost-effectiveness and distributional effects of a revenue-raising auction, grandfathering, and a generation performance standard as alternative approaches for distributing carbon emission allowances in the electricity sector. We solve

Global and Detailed Calculation of Tube Wall Temperature in a Process Furnace Steam Superheater

Chemie Ingenieur Technik, EarlyView.
This study presents a comparison between an iterative global model and multiple approaches to a new non‐iterative model with the purpose of predicting tube wall temperature of a superheater. The results show that the non‐iterative method achieves sufficient accuracy while improving the prediction of local temperature distribution and better ...

Thermal Degradation of PFAS in Different Scales: Measurement of Hydrogen Fluoride (HF)

Chemie Ingenieur Technik, EarlyView.
The communication article is about the challenges to balance a combustor in the case of fluorine when incinerating PFAS containing materials. Several analytical methods are compared: for continuous measurement, FTIR with TDLS. The detected fluorine species are further compared with results upon IC and pyrohydrolysis for discontinuous measurements in ...

Random forest regression for catalyst performance prediction and validation of tri‐reforming of methane (TRM)

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Carbon dioxide‐reduced hydrogen can be synthesized through various methods such as dry‐reforming (DRM), steam reforming (SMR), and partial oxidation (POX). Tri‐reforming of methane (TRM) is a promising technology which combines all the above‐mentioned processes for the simultaneous production of hydrogen and syngas with high energy efficiency.

U.S. Emissions Trading Markets for SO2 and NOx [PDF]

The U.S. Clean Air Act Amendments of 1990 initiated the first large experiment in the use of market-based regulation to control environmental problems with the introduction of an emissions trading program for sulfur dioxide emissions.

Effect of different flue gas recirculation rates on low‐NOx combustion characteristics: A numerical simulation based on the combustion process of a gas boiler

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract NOx emissions from gas boilers severely impact the environment, and flue gas recirculation (FGR) technology can effectively reduce such emissions, yet the effects of different FGR rates on combustion performance and NOx formation remain unclear. This study thus used numerical simulation (via ANSYS Fluent, adopting the realizable k‐ε turbulence

Civil aircraft trajectory analyses - impact of engine degradation on fuel burn and emissions [PDF]

, 2013
Commercial aviation and air traffic is still expected to grow by 4-5% annually in the future and thus the effect of aircraft operation on the environment and its consequences for the climate change is a major concern for all parties involved in the ...

A 1° x 1° resolution data set of historical anthropogenic trace gas emissions for the period 1890-1990

, 2001
An anthropogenic emissions data set has been constructed for CO2, CO, CH4, nonmethane volatile organic compounds, SO2, NOx, N2O, and NH3 spanning the period 1890–1990.
