Seeking advice on Texaco water-coal slurry technology for senior students’ graduation project
Thread Content
Since my graduation project focuses on Texaco water-coal slurry preparation technology, I would appreciate it if you could provide information on this topic, such as coal quality, additives, verification methods, etc. Thank you

This topic is too broad; for a graduation project, one should choose a more specific direction as a starting point. For example, the effect of different additives on the slurry-forming properties of a certain type of coal; otherwise, there is too much data.
I think this topic is too broad; it should be more specific. In-depth research, comparison, and summarization of the current cutting-edge issues in the field of coal-based slurry technology for coal chemical processing would be necessary. By taking into account the operational status of existing and under-construction facilities in the coal chemical industry both domestically and internationally, this topic could be of great help to your future work. The process is very important! Is there anything we can help you with? We definitely will.
The graduation project is on Texaco’s water-coal slurry preparation technology. Didn’t your supervisor provide you with some basic information? If you are not familiar with coal chemical engineering, this project definitely requires the help of a supervisor, in terms of technology and equipment (do you have rod mills or ball mills?) In aspects such as these, it’s impossible to complete a project relying solely on personal information and materials. Graduation project: 1. It is necessary to prepare extensive materials ； 2. Perform repeated experiments ； 3. Optimize the coal slurry ratio ； 4. To understand the characteristics of coal slurry required by Texaco ； 5. It is necessary to know how to use variance statistics to save experimental time……
When you mention slurry coal technology, do you mean the preparation of coal slurry? Slurry preparation mainly involves controlling the slurry concentration and viscosity as well as the size of the slurry particles. General process for preparing coal slurry: additives + coal grinding water + coal (coal slurry) + lime powder (required for coal types with high ash melting points, to lower the ash melting point) → grinder (rod mills are generally used nowadays, as they offer high efficiency and produce fewer large particles) → coal slurry discharge trough → low-pressure coal slurry pump → coal slurry tank. Here are some reference control parameters: Concentration: (61±2)%; Viscosity: 500–1200; Particle size: greater than 14 mesh and less than 1%, with over 80% being greater than 200 mesh. When controlling the concentration of the coal slurry, it is necessary to take into account not only the amount of water added but also the moisture content of the coal or the concentration of coal sludge. As the amount of additives used is very small, the water content in those additives need not be considered. Below are some data from production: Coal feed rate: 30 t/h; Water addition rate: 7 m3/h; Additive dosage: around 2.5 m3/h. The slurry produced has a concentration, viscosity, and particle size all within the specified limits. I hope the above can provide you with some suggestions; wish you success in completing your graduation project soon
