As the "green hydrogen-to-ammonia (H2A) - green ammonia-to-hydrogen (A2H)" cycle model proposed in the paper "Research Progress and Prospects of Hydrogen-Ammonia Green Cycle" published in the journal "Chemical Industry Progress" continues to be implemented, China's hydrogen-ammonia green energy industry is experiencing explosive growth. Recently, a series of major developments have emerged one after another: Goldwind Science & Technology plans to invest approximately 18.92 billion yuan in a wind power-to-hydrogen, ammonia and methanol project, the first phase of Envision's Chifeng 1.52 million-ton green ammonia project has been put into production, and Jidian Co., Ltd.'s Da'an green ammonia project has set four global records. These milestones mark that this emerging track, which can solve the problem of hydrogen storage and transportation and promote the decarbonization of traditional industries, has moved from the laboratory to large-scale commercial operation.

The efficient and environmentally sound treatment of oily sludge is a critical challenge for the petroleum industry's green transformation. This article systematically reviews the principles and characteristics of mainstream treatment methods, from traditional landfilling and incineration to modern biological and pyrolysis technologies, aiming to provide a clear reference for technology selection within the industry.

Oilfield sludge is a complex hazardous waste containing petroleum hydrocarbons, heavy metals, and chemicals. Traditional methods like landfill and incineration have drawbacks such as land occupation, resource waste, or secondary pollution (e.g., dioxins), failing to meet increasingly stringent environmental standards. Consequently, developing a technology capable of "volume reduction, harmless treatment, and resource recovery" for sludge is urgently needed. Thermal desorption technology has emerged as a key solution to this industry challenge due to its unique advantages.
