Abstract
Systems and methods are described for processing a high-temperature process fluid using a processing machine in a subsea location while protecting dynamic seals within the machine. In some examples a small portion of the process fluid is cooled using a cooling system the cooled process fluid is then directed towards the dynamic seals. In other examples the dynamic seals are shielded and isolated from the high temperature process fluid and cooler barrier fluid is circulated within an enclosed volume in proximity to the seal.
