This process flow diagram represents the working of an oil refinery. The oil is extracted from the ground using an oil pump and then this high-pressure crude oil is sent to a high-pressure separator passing through a fan cooler, this fan cooler reduces its temperature so that the gaseous form of resource can be separated and compressed further, and sent to natural gas processing plant.
This condensate (leftover) from the high-pressure separator is then sent to a low-pressure separator the gaseous fuel is again compressed and sent to a natural gas station but the liquid condensate left having high boiling points can be treated as liquid fuel and sent to an oil refinery where it can be distilled to more refined fuel such as petrol, kerosene oil, diesel, crude oil, etc.
