An oil refinery is a complex combination of advanced equipment, machinery and arteries. All kinds of valves, heat exchangers, steam boilers, distillation towers, hydraulic and gas turbines, separators, pumps and compressors, industrial valves, precision instruments, dryers and blowers can be seen in an oil or petrochemical complex. (Read the tips related to maintenance and repair of industrial pumps, maintenance and repair of turbines, repair and maintenance of compressors and maintenance and maintenance of industrial valves in these links)
Years and sometimes decades to engineer and build a petrochemical complex Or a refinery takes time, energy and capital. These industrial units are designed to work 24 hours a day, 7 days a week and 365 days a year, and hundreds and thousands of personnel work in them.
For example, in an oil complex, right after the start of operation, an important part of the costs is the maintenance of the refinery. Stopping production in an oil, gas or petrochemical complex can bring irreparable costs to the complex. Access to expert manpower, system for identifying maintenance and repairs and planning these matters, along with issues related to the supply of required parts and consumables, is one of the challenges of this field.
The value of physical assets exposed to thousands of threats!
All the equipment in an industrial unit is against the erosion caused by the passage of time. The production process, in which high pressure, high temperature and corrosive materials are among the normal working conditions of the equipment, creates a harsh and damaging environment for the assets. That is why obsolescence and breakdowns are an inseparable part of work, but maintenance and repair of petroleum equipment based on a well-prioritized schedule based on reliability analysis can reduce the effects of these breakdowns. minimize
Preventive matters in repair and maintenance of petroleum equipment
Preventive maintenance and repairs are carried out at regular intervals that are planned based on the age and remaining life of the equipment. Repetitive visits and maintenance operations are scheduled based on the probability and consequences of failure of the equipment in question. This type of maintenance is usually done when the equipment is shut down or out of service in order to avoid unnecessary visits and imposed costs. A variety of tasks such as cleaning, wrenching, oil change, lubrication or changing filters, etc. are among the preventive activities of Net. When it comes to the preventive maintenance of oil equipment, balancing the three parameters of cost, risk and performance is inevitable. In order to achieve the optimal balance in this triangle, the executive power of personnel, access to tools and parts, and of course correct executive planning are considered work requirements.
Equipment Care, an important part of the tasks of the Maintenance and Repair Team
Predictive Net, however, as an always-running process, monitors the current state of the equipment. This is what we also know as condition monitoring, and its correct implementation is an inseparable part of the oil and petrochemical equipment repair and maintenance program. Information can be measured by sensors and in a system or by specialist forces with the help of special tools and entered into the physical asset management software system or CMMS software. Many agendas in this field include visual inspection and monitoring the condition of components and systems. This work requires high technical ability and detailed planning to create an optimal situation from the point of view of risk and cost. Visual inspection of the condition of a valve or pump in terms of possible leaks, inspection of a blower in terms of unusual sound and vibration, non-destructive tests that are performed on fixed and rotating equipment, such as detecting cracks, ultrasonic tests, oil analysis, etc. . All are types of agendas whose purpose is to prevent failure.
