Air leaving a compressor is hot, dirty, and wet – which can damage and shorten the life of downstream equipment, such as valves and cylinders. Before this air can be used, it needs to be cleaned and lubricated. That's where an FRL Unit comes in! An FRL unit combines a filter, regulator, and lubricator into one component to keep air compressor systems in optimal working condition.
FRL Components
An FRL is comprised of three primary components:
1. Airline filter
2. Pressure regulator
3. Lubricator
In order to ensure the normal production of gas storage, Xinjiang Oilfield Gas Production Plant has set up a technical reform team. The technician found the cause of the damage of the valve by repeatedly disassembling the gas valve and simulating the calculation. First, the process gas contains hydrogen sulfide and carbon dioxide gas, and forms a tar-like substance having a viscous force under the action of the condensate. These tar-like substances accumulate on the valve body, which will affect the opening and closing of the valve plate, and its acid corrosion will make the valve become brittle and hard and eventually break. Second, under the simulation calculation of professional software, it was found that the number of impacts of the valve reached 2.85 million times per day. This is the main cause of damage to the valve plate, spring, and seat.
Through repeated discussions and field trials, the technical reform team has made three improvements to the valve. First, the material was changed, and a Fe-Ni-based precipitation hardening type corrosion-resistant alloy was selected as the spring main material. The alloy has good stability in a reducing medium, especially in an acidic medium such as hydrogen sulfide or carbon dioxide, and the use temperature can reach 400 degrees Celsius. Secondly, the valve plate adopts the integral mesh valve plate structure, which can ensure that even if individual springs are damaged, the ring valves can be connected together to ensure that the action of each ring valve is consistent, which effectively improves the working condition of the valve plate and is beneficial to the valve. Improve the economics of the valve. Increased valve gas passages can effectively reduce the weight of the valve. The third is to cancel the buffer plate of the original valve, reduce the impact of the valve, and optimize the opening and closing angle of the valve through simulation calculation.
After the technician optimizes the material and structure of the valve, the valve is returned to the No. 5 compressor of the gas storage. After 4,300 hours of test operation, the gas valve was still intact and the compressor was working properly. Compared with before the transformation, the compressor failure rate dropped to 6%, and the number of venting times decreased by more than 60%.
It is understood that Xinjiang Gas Production Plant has improved the maintenance cost of nearly 3 million yuan per year through the system modification of the compressor gas valve, and at the same time reduced the labor intensity of employees, and also provided valuable experience for the handling of gas valve compressor gas valve failure. .
