The petroleum waste heat temperature refers to the temperature of waste heat or byproducts generated during petroleum processing. Since petroleum processing involves different processes and equipment, the temperature range of the waste heat of petroleum varies, and in general, the waste heat temperature in petroleum refining and refining processes is typically between 300 degrees celsius and 700 degrees celsius. For example, in petroleum refining, the waste heat temperature generated by cracking furnaces and reformers is around 500 degrees celsius; the temperature of the waste heat generated by the catalytic cracking device is generally above 600 ℃; the temperature of the waste heat generated by the booster pump, the compressor and other equipment can reach more than 300 ℃.
These high temperature petroleum waste heat, if not utilized effectively, would result in waste of energy. Therefore, in the petroleum processing industry, a waste heat recovery technology is generally adopted to convert the waste heat of petroleum into heat energy or electric energy, so as to improve the utilization efficiency of energy and reduce the requirement for external energy. The waste heat recovery can be applied to equipment such as a steam generator, a heat exchanger, a generator set and the like, and is used for heating, steam production, power generation and the like.
The general oilfield waste heat recycling system is a system capable of effectively recycling and utilizing waste heat generated by an oilfield. The system converts the waste heat of the oil field into usable heat energy or electric energy by adopting equipment such as a heat exchanger, a steam generator, a generator set and the like. The working principle of the system is as follows: heat exchanger: the high-temperature waste heat generated in the oil field exploitation process exchanges heat with the medium to be heated through a heat exchanger, so that the waste heat is transferred to the medium to be heated; steam generator: in the heat exchange process, the medium to be heated (typically water) is heated to generate steam; steam power machine: the steam is conveyed to a generator set through a pipeline to drive a steam turbine or a steam turbine generator set to generate power; waste heat recovery: the low-temperature waste heat discharged by the steam generator can be used for heating other technological processes again, so that the energy utilization efficiency is improved, but the high-temperature waste heat generated after general petroleum is treated also contains certain waste water, and the waste water is usually extracted and discharged to be directly used, so that the extracted waste water is wasted, and the utilization rate of the waste heat of an oil field is reduced.
