“…However, in the case of the ZLD, the treatment also includes evaporation and crystallization steps, in order to achieve total freshwater recovery and zero liquid waste. Multi Effect Distillation (MED) (Ma et al, 2021) is the most frequently used evaporation process, while brine crystallization (Lassesson et al, 2021;Xevgenos et al, 2015b) is a popular method for salt mixture recovery. However, the salts gathered in this manner have no market value and must be treated as waste, incurring management and disposal costs.…”

“…For example, by combining liquefaction technology and chemical technology, one of the issues of current economic development research and consideration is to give the best results in the production of chemical coal; Although the research and application of coal chemical co-production technology is in the stage of continuous testing and innovation in the modern coal industry, some of the research results have been applied in the business sector with good results. Deeper development of research technology will provide more support and better support for actual production [4][5].…”

To gain a deeper understanding of the current application status of carbon capture, utilization, and storage (CCUS) technology in modern coal chemical projects aimed at reducing emissions in the chemical industry, a study on the application of CCUS technology in emission reduction in the chemical industry was proposed. This article provides a detailed summary of the application status of CCUS technology in the global chemical industry, comprehensively sorts out its technical classification and characteristics, and deeply analyzes the carbon emission characteristics of modern coal chemical industry. On this basis, a comprehensive analysis was conducted on the main technical, economic, and policy issues faced by the modern coal chemical industry in promoting the application of CCUS technology. Through the analysis and research of these issues, some suggestions have been made, including strengthening top-level planning, focusing on solving CCUS technology challenges, enhancing policy support, etc., to promote better progress in the modern coal chemical industry in carbon capture technology engineering demonstration and low-carbon development.

“…Coal gasification plants, which are major CCI sites [2,5,6,8,[43][44][45][46][47], are important representative industrial sites for studying the status of CCI pollution. To this end, the authors chose a coal gasification plant in Northwest China (38 • 10 08 N, 106 • 3 45 E) as the study area, which is located at the edge of the Mausu Desert and is in a temperate arid climatic zone.…”

Coal chemical industry (CCI) sites are characterized by complex environmental media, combined heavy metal pollution, and diverse exposure routes. However, existing human health risk assessment (HHRA) methods have multiple drawbacks, such as their small scope of application, limited assessment factors, and insufficient case applications. After 128 soil samples were collected, the contents of Be, V, Ni, Cu, Zn, As, Cd and Hg in the soils were analyzed based on general risk assessment guideline of China. Then, risk levels were calculated based on oral ingestion, skin contact and inhalation as the main exposure routes to compare and screen priority heavy metals. Furthermore, control values were identified through a contribution rate calculation model when CR > 10−6 or HQ > 1. As reference values, risk thresholds were proposed for heavy metals, and then a soil HHRA framework for the CCI site was constructed. Under the three exposure routes, the total CR was As > 10−6, and the total HQ was 1 > As > Cd; the HHRs related to As and V via the oral ingestion, dermal contact, and inhalation pathways were 76.67%, 13.13%, and 10.18% and 1.66%, 0, and 98.34%, respectively. The risk control value of As was 1.59 mg/kg and that of V was 25.1 mg/kg. Based on these results, the threshold values for priority heavy metals should be based on comprehensive considerations of the elemental background of a specific area, the contaminant criteria in different areas, the regional industrial development plan, and the most important control criterion, as well as the control value. Through the development of an HHRA framework and case verification, the authors of this article aim to guide CCI managers in screening priority heavy metals, formulating protection measures, developing improved operational procedures and improving the HHRA system for polluted CCI sites.
