The Cryogenic Carbon CaptureTM (CCC) process is a retrofit, post-combustion technology that desublimates CO2 in the flue gas and produces a separate liquid CO2 product. This project focuses on the energy-storing version of this process, CCC ESTM. During off-peak hours, CCC ESTM generates more refrigerant than is needed for the process, which is stored in an insulated vessel as a liquid at the l...

Extreme cold events in natural gas demand are characterized by unusual dynamics that makes modeling the characteristics of the gas demand during extreme cold events a challenging task. This unusual dynamics is in the form of hysteresis, possibly due to human behavioral response to extreme weather conditions. To natural gas distribution utilities, extreme cold events represent high risk events g...

Characterization and evaluation of a biological submerged filter was carried out on a full-scale pilot plant performing removal of biochemical oxygen demand (BOD) and total nitrogen (TN) from pre-treated urban wastewater. The average influent values of BOD5, chemical oxygen demand (COD) and TN were 370, 1,015 and 60 mg/L, respectively. The pilot plant produced good discharge quality during stea...

  This paper aimed at estimation of the per capita consumption of electricity in residential sector based on economic indicators in Iran. The Genetic Algorithm Electricity Demand Model (GAEDM) was developed based on the past data using the genetic algorithm approach (GAA). The economic indicators used during the model development include: gross domestic product (GDP) in terms of per capita and ...

With the reduction of natural gas and petroleum sources and subsequent increases in their costs, energy from coal is becoming increasingly popular. However, coal is not a clean technology, so with this demand comes a demand to make this energy source more environmentally friendly. Trace elements, such as mercury, arsenic, and selenium, are highly volatile and are known to escape into the atmosp...

Natural gas demand in the United States has been increasing for the last 15 years and is projected to grow substantially in the next 20 years. Meeting this growing demand will require an accompanying increase in supply, which is expected to come mostly from additional production in the United States. The prospect of increased U.S. production has led to ongoing efforts both to better assess our ...

This study analyzes factors affecting the price of South Korea’s Certified Emission Reduction (CER) using statistical methods. CER refers to the transaction price for the amount of carbon emitted. Analysis of results found a co-integration relationship among the price of South Korea’s CER, oil price (WTI), and South Korea’s maximum electric power demand, which means that there is a long-term re...
