Get PriceDuring oil and natural gas production, so-called produced water comprises the largest byproduct stream. In addition, many oil and gas operations are augmented via injection of hydraulic fracturing (HF) fluids into the formation. Both produced water and HF fluids may contain hundreds of individual chemicals, some known to be detrimental to public health and the environment.

Get PriceYadav et al. (2010) used RM for the sequestration of CO 2 as an important greenhouse gas. The authors prepared three different size fractions of RM (RM I, RM II, and RM III) of varying densities (1.5-2.2 g cm −3) and used them for carbonation in a stainless-steel reaction chamber at a fixed pressure of 3.5 bar. Carbonation of RM was studied as a function of reaction time (0.5-12 h) and a
Get PriceASPEN Plus simulations have been created for a CO{sub 2} capture process based on adsorption by monoethanolamine (MEA). Three separate simulations were developed, one each for the flue gas scrubbing, recovery, and purification sections of the process. Although intended to work together, each simulation can be used and executed independently.
Get PriceFirst-Steps Toward Achieving Healthful Indoor Air Quality Many types of indoor pollution problems are found in homes. The most effective approach to solving these problems is usually to remove or reduce the sources of indoor pollution. Ventilation helps remove indoor air pollutants, but not as effectively as source reduction.
