Within the complex and highly integrated production system of an oil refinery, temperature and pressure are undoubtedly the most critical operating parameters. They are like the “vital signs” of the plant, accurately reflecting the health of the production process. Any incorrect measurement of temperature and pressure can be like a “bomb” ready to explode at any time, putting the equipment into an abnormal operating state and even triggering catastrophic safety accidents. Therefore, the establishment of a professional temperature and pressure calibration laboratory is extremely urgent.
Take the distillation tower, a core piece of equipment, as an example. Its operating principle is to separate different petroleum components based on their boiling point differences. In this process, precise control of temperature and pressure is as crucial as walking on a tightrope. If there is even a slight deviation in temperature measurement, it may cause the actual temperature inside the tower to far exceed the expected value, causing light components to vaporize prematurely, thus leading to pressure imbalance inside the tower. This unstable pressure environment is highly likely to cause overpressure in the tower body, resulting in material leakage from the seals. Once a leak occurs, flammable and explosive oil products come into contact with air and can ignite into a huge fire instantly when encountering a source of ignition, with disastrous consequences.
Through regular calibration by the calibration laboratory, professional technicians can use high-precision standard instruments to carefully compare and adjust various temperature and pressure measuring instruments. In this way, deviations in instrument measurements can be detected and corrected in a timely manner, ensuring that every measurement data is accurate. This not only builds a solid defense line for the safe production of the oil refinery but also effectively maintains the stable operation of production, avoiding unexpected production stoppages caused by measurement errors and ensuring the continuous and efficient operation of the enterprise.
