What analysis instruments are required for hydrogen production from methanol and the hydrogenation of gasoline and diesel?
Thread Content
We are setting up new methanol-to-hydrogen and hydroprocessing units for gasoline and diesel. I would like to ask everyone what analysis instruments are needed, and where it’s best to purchase them – ones that are durable and cost-effective. Imported ones aren’t necessary; domestic products will do
At the very least, a gas chromatograph is needed. Gas chromatography is further divided into domestic and foreign-made types. Choose between domestic or foreign-made based on your price range. Generally, domestic ones cost around 30,000 to 60,000. Those made abroad cost over 100,000. There are many domestic options available. For analysis related to gas phases, you can look on forums; I already posted a thread on this topic before, so go and take a look.
Thank you. However, gas chromatography alone is not enough; regular testing equipment for gasoline and diesel is also required. We have just set up this facility and don’t understand many things. Hydrogen testing is also needed – could someone please provide detailed instructions? Thanks:$
Generally, an online hydrogen analyzer is required; there is a big difference between domestic and imported ones, and their performance and lifespan also vary
We have worked on hydrogen production from methanol. At that time, the manufacturer of the hydrogen production equipment provided devices for analyzing the hydrogen produced – a gas chromatograph equipped with a dual-channel thermal conductivity detector and an FID, as well as gas collection cylinders and standard gases. These were used to analyze the conversion gas, the product gas, and methanol aqueous solutions
Thank you. Then who knows the instruments used for routine analysis of the raw materials and products in diesel and gasoline hydrogenation? The raw materials are coke or catalytic fuel; please help prepare a list. Thank you
Here’s a link for you: http://bbs.hcbbs.com/thread-400293-1-1.html. Start reading from entry 387. It’s great that it covers several of your fields. Methanol, gasoline and diesel. It just lacks hydrogenation. First, determine your analysis items, and then you can decide on the instrument. Find the analysis item in the process flow. If you do it all, you also need to consider the gas and water analysis for utilities.
It’s already been explained clearly above.
First, you need a chromatograph, and then you also need a sulfur content analyzer, an ash content analyzer, a residue carbon analyzer, a boiling range analyzer, a flash point analyzer, as well as instruments for determining the freezing point and cold filter plugging point, and a moisture content analyzer, among others.
An analyzer for high-purity hydrogen is essential (and it must be explosion-proof). For domestic options, it is recommended to use the analytical instruments produced by Xi’an Jueneng Instruments; they perform very well in petrochemical enterprises~
