High-sulfur oil refers to crude oil trading varieties that do not meet the standards of futures contracts during commodity futures trading. The sulfur and hydrogen content of high sulfur oil is higher than the standard required by futures contract.

Extension of knowledge points:

The processing of high-sulfur oil is corrosive, and the content of hydrogen sulfide produced by processing is high, which brings high risks to the processing process and the processing cost will rise.

At present, most refineries in China process high-sulfur oil. With the deterioration of crude oil and the high price of crude oil, the cost control of crude oil makes refineries have to process a large number of high-sulfur and high-acid crude oil.
