Well this entire situation as you described is actually being seriously discussed. China trades everything in yuans, the EU in euros, and the world falls apart into several big currency zones: US dollar zone, euro zone, yuan zone and a few others possibly. Inter-zone trade will diminish substantially, de-globalisation will kick in. This is the third alternative scenario (the first one is the US dollar as the global currency, that is what we have now; the second is the IMF with SDRs as the global central bank).
What is often forgotten is that the situation of the last 20 years with a single world reserve currency is unique to the last 20 years of the human history. Immediately prior to that, the world was divided into a US dollar zone and a rouble zone, which was huge - it was like a forth of third of the world (though it was quite smaller than the US'). The Soviet Union did not run substantial trade deficits, instead it lent to or invested in other countries within the zone. China apparently is doing the same while building the yuan zone - setting up refineries, investing in infrastructure etc. The SU did the same in Africa and elsewhere back in the middle of 20th century - huge dam in Egypt and all sorts of things here and there. At least for a while it should work, as the experience shows.
Prior to WWII the world was divided between Britain, the US, Germany, Japan and may be some others. Correct me if I am wrong, but a global reserve currency, as such, did not exist. If any country wanted to have reserves, it tried to accumulate gold or other tangibles. And so on and so forth.
The current global US dollar system implies a certain international division of labor - some territories supply raw materials (Middle East, FSU, Africa etc), some run lower-end manufacturing and other low-value industries (China, India) etc. The "golden billion" countries sit atop the value added chain - they run high-end manufacturing, financial services and services in general, high tech. A dissolution of the world's single currency zone into several ones would lead to each currency zone having to build the entire value chain (except absent raw materials) within its borders.
For the "golden billion" this will mean that substantial chunks of population will become poorer as they will have to give up lucrative high-end jobs and take upon poorer rewarded "Chinese"-type ones. This process is underway, as manufacturing began migrating back to the US from China, and Southern/Central Europe are going through "austerity' (actually, a euphemism for this process). China, on the contrary, has been benefiting from it, and will benefit at least for a while, as it finalizes the absorption of the high end of the value chain.
Overall, this will be a regress, because the new separate currency markets will be smaller than a single global one, and therefore, arguably, less potent in terms of innovation and investment. But a regress looks inevitable anyway. Hopefully, it will be cyclical.
In addition, this new divided world will be a more dangerous place as the new zones will compete for the resources, as the experience of the first half of the 20th century confirms.
Alternatively, the US+ may try to maintain their dominance and income levels, but given the realities, they will not be able to do so other than by making other parts of the world (substantially) poorer. This will make the world a far more dangerous place for everyone outside the "golden billion", but in this case China will probably be a stabilizing counter-force, until itself becoming everyone's headache. China no longer needs the US, as the Chinese have effectively built the entire value chain already, and are able to produce everything that they need on their own, including the most sophisticated things (they are even growing their high-end military exports). That's why the US will have hard time taking upon China.
In fact, the status of a "reserve" currency requires only one thing - ability to supply everything that a potential consumer may need to buy, including vital goods, in sufficient quantities. Why would you hold a pile of foreign currency banknotes stashed in your safe box? When you are sure that you can buy everything you want using them. The degree of labor division has progressed so much in China that they can sell you anything that you will ever need. The Chinese no longer need the US consumers to run the economy.
Regarding the refineries - a while ago we had a discussion that the Iran sanction would likely be circumvented with the help of intermediaries. So what we have now - Iran sells oil to China using yuan as you described, China refines and sells (Chinese) products to the US. Everyone is happy - the US have the sanctions intact and get fuel, Iran sells oil and gets revenue, China is benefiting from others' chest-beating and goes on building the yuan zone. Yeah. Again, the rumors are that the Chinese do intend on building the yuan zone and already discuss it openly in, eh, private circles.
Also, refining capacity is a strategic asset, that, in particular, feeds the military in times of conflict. From this perspective, the world's refining capacity does not matter when making the strategic development plans.
