Utilization of oil hydrogenation waste
Thread Content
We have a project dealing with the waste resulting from the hydrogenation of large quantities of vegetable oils – this waste contains 40%–50% oil, 10%–20% diatomite, and used catalysts. In black-gray lumps). We want to first separate the used oil and extract the remaining catalyst. The waste grease here should be a good raw material for biodiesel. Are there any colleagues who work in this field? Please advise us on how to separate the grease; let’s work together. QQ939164390
What is the cost of this waste? It is recommended to conduct a cost calculation first, and then determine the quantity produced Whether there are economies of scale – if the quantity is large and the cost is low, then it is indeed worth paying attention to.
Oils are not counted as part of the costs; with over 100 tons per month, it’s unclear whether there is any potential for this business. We have tried various methods for oil removal, but the results have been poor or the costs too high. I was wondering if any forum members could offer some advice.
100 tons per month is too small; a scale of 3,000 tons per year is what constitutes pilot testing； Also, this kind of raw material must have a cost. What about the various specifications of this oil?
The cost of the raw materials is included in the cost of recycling the waste catalysts. In a sense, oils and fats are considered waste that needs to be removed; it would be good if the cost of removal could be balanced with the benefits obtained. When heated with oil, a vigorous reaction occurs: it melts at around 70 degrees, solidifies upon cooling, and floats on the surface of the liquid as a yellowish-white solid. I don’t understand other indicators; I haven’t worked on them. Plan to sell this oil to biodiesel manufacturers.
Is its composition still glycerides? What is the acid value? What is the iodine value? Saponification value?
