Different systems have different recipes performance results. Common sense, heat oil picture, base oil hydrogenation whole basis of the national standard can produce high-quality heat transfer oil products, but the experimental result is a huge difference. If these are not ideal for conducting oil re-determined formula, Changsha heat transfer oil, readjust the poor quality of the HTF formulation, it is completely extend the life of old HTF. The primary task is to make online scrap regeneration HTF should no longer continue coke, even before the dissolution of carbon formed in the system, rebuild the HTF system cleaning system, conducting on-line (non-stop furnace) technology to succeed. But for different useful life of HTF, HTF different systems are required to do first original recipe small test program to determine the amount, to the effect is obvious. We tested the most famous of domestic conducting oil, heat transfer oil supplier, at 310 ℃ heat, about 80-90 ℃ oxidation, after 720h, the oil was turned into tar-like black and become sticky, with a clear oxide interface. These oils have gone through the examination of relevant state departments. Why is this so? The most fundamental reason is: HTF formulation is not comprehensive enough, we can not fully meet China's specific national conditions. That requires the use of a closed system, and the user has to use the open system, it is a matter of respect. Recipe also stressed in sealed under nitrogen stable, heat oil producers, while in contact with the air of the open system - Determination of thermal oxidation stability only that 175 ℃ 72h can. To know the temperature of the high slot, although the general requirements below 70 ℃, but also a considerable proportion of the upper tank temperature above 100 ℃, and in a system, the high-temperature portion and the upper portion of the lower low temperature heat convection certain meeting, oil oxidation products at high temperatures is inevitable.
