Differences among several tetra-carbon products
Thread Content
Dear experts: I work in the third-party warehousing industry, but I’m not very familiar with the various products available on the market, so I’m here to seek your advice. Currently, tank clients usually change the product type, but it is generally referred to as C4, or butane. When broken down further, there are numerous names, and the qualities vary; moreover, they cannot be stored together, which is quite troublesome. Could you please help me get some information on the following product names? I’d like to know about their quality, classification, and the purposes for which they are used. Thank you! 1. Cracked C4 2. Crude C4 3. Pre-etherification C4 4. Post-etherification C4 5. Civilian liquefied gas 6. High-purity isobutylene. Which combinations of these can be mixed without any problems? Please help answer this question. Thank you. . .
The difference between each type lies mainly in the olefin content.
It’s mainly a difference in components. It is mainly because the composition of butadiene, 1-butene, 2-butene, isobutylene, and butane inside is different.
You are in the warehousing business; it should be the owner who provides information on the properties of the materials. It’s not up to you to decide whether mixing them is possible or not. For C4, the main difference lies in the amount of light components (liquefied hydrocarbons) present. For the sake of efficiency and versatility, it is recommended to raise the pressure in C4 storage tanks to 1.77 Mpag uniformly
