How much does a refinery operator with 15+ years experience in USA expect to make at Aramco in Saudi per month? What language is used in the refinery?

$ 20,000 per month minimum, English is the international language

Its between the range of USD5K to USD7K. All inclusive of allowances. Both Arabic and English is mostly spoken and English is used for official matters.

With this much experience one can easily get a highly paid position at Saudi Aramco. English and Arabic are more preferable
