Progress of the oil-enriched lignite upgrading project in Shenmu, Shaanxi
Thread Content
Those who are aware of the project to upgrade oil-rich lignite in Shenmu, Shaanxi, please come and discuss it. To get things started, it is said that this project utilizes DG solid heat carrier low-temperature carbonization technology; it is capable of processing 1.2 million tons of raw coal per year, and it also includes a facility for the comprehensive utilization of low-temperature tar at a capacity of 120,000 tons per year. The total investment in this project is around 750 million yuan. Once operational, the project will produce 82,000 tons of diesel, 23,000 tons of gasoline, and 720,000 tons of semi-coke. The detailed design was carried out by the Second Chemical Engineering Institute and Yueyang Engineering Design Company, and it is currently in the commissioning phase. Those who are aware of the latest situation, please share your insights; it would be great if there are photos from the scene, hehe.
Don’t be fascinated by it; it’s just a legend. I’ve been driving for over a year yet I still can’t drive well; isn’t it clear then what my driving skills are like?
All new technologies go through a process of improvement; there’s no need to reject them outright. It turns out that the problem of separating oil vapor from solids in the dry distillation furnace was related to the cyclone separators used at Qingdao University of Science and Technology; certain technical limitations made it impossible to achieve a separation level of below 5 microns, which essentially became a major obstacle for these cyclones ； The tar that results later on cannot have the incoming dust separated from it using super centrifuges (which can separate particles down to 30 microns); this is probably the main reason why this portion of oil cannot be extracted. Otherwise, the ash content in the asphaltenes would exceed acceptable levels, and the products produced would be unsellable. Now, Fuyou and another company are carrying out technical upgrades, using a technology similar to membrane separation to remove dust. It is estimated that we will get some results around July this year; we will continue to wait
What are the criteria for separating oil, vapor, and solids from the retorting furnace?
Hello, I would like to ask about the brown coal coking project – how is it? And is there a big difference between it and the petrochemical industry, in terms of equipment and processes?
The issue of the loading racks for equipment and pipelines forming bridges is also the fundamental reason why the installation cannot be started:)
It seems that the technology is not yet mature, and there are still many issues that need to be resolved. Separating oil, gas, and solids is very difficult, and this problem has not been solved yet.
