This paper describes data of an integrated process, cryogenic energy storage system combined with liquefied natural gas (LNG) regasification process. The data in this paper is associated with the article entitled "Conceptual Design and Exergy Analysis of Combined Cryogenic Energy Storage and LNG Regasification Processes: Cold and Power Integration" (Lee et al., 2017) [1]. The data includes the ...

background: chlorophenols are classified as priority toxic pollutants. these acidic organic compounds present a serious potential hazard for human health and aquatic life. chlorophenols accumulate in water, soil and air due to high stability, and impart an unpleasant taste and odor to drinking water and can exert negative effects on different biological processes. among the different methods of...

Hydrogen (H2) is known for its clean energy characteristics. Its separation and purification to produce high-purity H2 becoming essential promoting a economy. There are several technologies, such as pressure swing adsorption, membrane, cryogenic, which can be adopted H2; however, each standalone technology has own pros cons. Unlike technology, the integration of technologies shown significant p...

nowadays, membrane processes are widely used for high purity nitrogen production. separation of air by membranes is a flexible process in which the investment and operational costs are lower than for example adsorption or cryogenic processes. such processes are based on relative permeability of air components which are transported by the pressure difference between two sides of the membrane. ma...

This paper is a state-of-the-art review of the use of cryogenic cooling using liquefied gases in machining. The review is classified into two major categories namely, cryogenic processing and cryogenic machining. In cryogenic processing also known as cryo-processing the cutting tool material is subjected to cryogenic temperatures as a part of its heat treatment process. The majority of the repo...

Increasing concentrations of greenhouse gases (GHGs) such as CO2 in the atmosphere is a global warming. Human activities are a major cause of increased CO2 concentration in atmosphere, as in recent decade, two-third of greenhouse effect was caused by human activities. Carbon capture and storage (CCS) is a major strategy that can be used to reduce GHGs emission. There are three methods for CCS: ...

Cryogenic treatment (CT) is the supplementary process to conventional heat treatment process in steels, by deep–freezing materials at cryogenic temperatures to enhance the mechanical and physical properties of materials being treated. Cryogenic treatment (CT) of materials has shown significant improvement in their properties .Various advantages like increase in hardness, increase in wear resist...

One key unit operation in oxyfuel power plants is the CO2 purification unit (CPU), expected to be needed in most of oxyfuel installations to reduce the content of non-condensable gases (mainly O2, N2 and Ar), originated from the oxidant excess required for the combustion, air in-leakages and the non-100% purity of the O2 produced in the cryogenic ASU. Auto-refrigerated cryogenic processes are t...

Cryogenic machining is considered as the most sustainable alternative to conventional flood-cooled, near-dry and dry machining approaches in machining processes. This paper presents the application of a sustainability evaluation methodology for manufacturing processes, focusing on cryogenic machining processes. The methodology used here involves a metrics-based Process Sustainability Index (Pro...
