I would like to ask experts how to process the following heavy oil

The metal content is a bit high; coking might be more suitable.
Thank you. With such high viscosity and sulfur content, is it possible to use it for coking? Also, what about pressure and viscosity reduction for such quality?
OK, great! Thank you so much! :victory::handshake
I’m not an expert, so I’d like to ask: With oil prices so low these days, is there still any profit margin for such low-quality oil?
Processing such oils by first carrying out hydrogenation to remove metals, sulfur, nitrogen, residue, etc., and then hydrocracking and catalytic cracking can yield more light fuel oils. The delayed coking process produces a large amount of low-quality coke as a by-product. Of course, it is also possible to choose the fluidized coking-gasification process.
Please have Mr. Yu inform us of the purpose of focusing on heavy oil processing; email: william724@sohu.com.
1. It’s certainly possible to proceed with coking. 2. I’m not sure what the purpose of reducing viscosity is – is it to directly produce fuel oil? There’s no need for that
This post was last edited by karamay on 2015-10-12 at 13:04. Processing plans: 1. Crude oil hydrogenation --> catalytic cracking; 2. Coking; 3. Solvent deasphalting --> catalytic cracking. Where does this oil come from? Why is its aromatic content so high? It doesn’t seem to be crude oil. It’s not all oil either.
The oil from South America – if possible, give me your email address and I’ll send you a more detailed analysis report, one based on an analysis of the crude oil itself
