Shijiazhuang Refining & Chemical: Revitalizing Old Facilities 2019-03-22 Source: Sinopec News Network, Petrochemical News. The Party branch of the First Oil Refining Operations Department at Shijiazhuang Refining & Chemical adheres to lean management principles and uses party building to support its core tasks; it has been awarded the title of Advanced Grassroots Party Branch at Shijiazhuang Refining & Chemical on multiple occasions, and in 2018 it was honored as an Advanced Grassroots Party Organization by the group company. With the implementation of the points system, innovation, excellence, and achievement have gradually become the conscious actions of Party members. To address the long-standing problem of minor leaks in some pumps, the Party members in the equipment team organized technical efforts to modify the mechanical seals; by employing new technologies, they improved the operating conditions of these devices, thereby completely resolving the issue of seal leakage in the pumps. To address the issue of oil mist leakage from the oil mist lubrication system of the on-site pumps, six additional oil mist recovery systems were installed to ensure sealed emission and recovery, effectively solving the problem and yielding significant environmental benefits. During the annual HSSE inspection, the clean and orderly site environment of the facility, along with the use of new technologies, were frequently praised by the experts from the inspection team.

Explanation of how the oil mist lubrication system ensures no leakage of oil mist at the installation site: To ensure that there is no leakage of oil mist at the site where oil mist lubrication is used, it is necessary that there be no leaks at any of the three locations – namely, the end caps at both ends of the pump (the thrust side and the radial side) as well as the drain port of the oil collection box. Our company has pioneered a three-point residual mist recovery solution by combining theory with practice. Recovery principle: Compressed air enters the vacuum system of the recovery unit; the negative pressure generated by this vacuum system draws in the residual mist that leaks from the end caps at both ends of the pump (thrust side and radial side) as well as from the oil collection box’s exhaust openings, and transports it to the filtration system of the oil mist recovery unit. Through two stages of filtration, the lubricating oil in the mixed gas is removed, and finally the air is released into the atmosphere. The schematic diagram of oil mist recovery is shown in Figure 1, while the installation diagram for pump oil mist recovery is shown in Figure 2. Since there are no recovery ports for the oil mist that leaks from both ends of the pump (the thrust side and the radial side), it is not possible to install pipe fittings or pipelines for recovery. Therefore, our company has developed a patented recovery shield that is installed at both ends of the pump to carry out recovery operations, thereby ensuring that no oil mist leaks anywhere at the site. To ensure optimal lubrication at the site, our company has developed a patented oil mist recovery regulator. This regulator enables regulated negative pressure to be applied to address three leakage points, thereby recovering oil mist while ensuring the best possible lubrication for the pumps.
