Among the various refining processes mentioned above, hydrogenation and hydrocracking hold the greatest potential for development in the future.
In comparison, by how many years were we late in starting? Hehe
What about the development of those born in the 1970s? The trend toward cleaner products should become increasingly important. Given the serious issue of low-quality crude oil, there is an urgent need to improve current processing methods and technologies; relying solely on delayed coking is too crude, haha!
Has the refining industry not developed since 1975? With crude oil becoming increasingly heavy and of lower quality, as well as environmental regulations becoming stricter, it has become increasingly urgent to produce environmentally friendly clean products.
