Sinokle Completes KHC Filter Element Replacement for Luoyang Refinery
Recently, at the invitation of Luoyang Refinery, Sinokle's after-sales service team traveled to the production site of its delayed coking unit to provide on-site guidance and dedicated services for the installation and replacement of filter elements in the KHC Coalescing Filter for emulsified sour water deoiling facilities.
The KHC Coalescing Filter is a patented technology, with physical oil-water separation process, independently developed by Sinokle, specifically designed for treating emulsified and acidic wastewater in refineries. After the operating cycle of the filter elements reached the designed limit, our service team worked closely with the refinery's maintenance department to complete the replacement efficiently and safely. This service not only guarantees the long-term, stable, and high-performance operation of the unit in the next cycle but also demonstrates the critical value of professional after-sales service in modern refining production.
The replaced filter elements are the core components for wastewater deoiling, serving as a vital barrier to protect downstream equipment, ensure product quality, and maintain process stability. As the performance of filter media degrades with accumulated operating time, Replacement is a necessary measure to prevent unexpected shutdowns and sustain optimal operating conditions.
Faced with the complex on-site environment of the refinery—characterized by high temperature, high pressure, flammability, explosiveness, and high hydrogen sulfide content—the service team, in collaboration with the refinery's maintenance department, developed a comprehensive and detailed plan. Prior to the operation, the technical teams of both parties conducted in-depth communication, accurately determining the optimal replacement time based on the unit's operating data. The service team delivered brand-new spare parts meeting strict quality standards to the site in advance and completed all necessary reviews and safety briefings.
During the operation, the highest standards of the refinery's HSE (Health, Safety, Environment) management system were strictly followed. After the technicians completed system isolation, pressure relief, purging, and testing, and confirmed the safety conditions through multi-party verification, professional service engineers worked in coordination with the refinery's maintenance staff. Leveraging specialized tools and proven procedures, they efficiently disassembled the filter manhole, removed the saturated filter elements, and performed a thorough cleaning and inspection of the filter interior. Subsequently, new filter elements were precisely installed, with strict adherence to sealing and resetting procedures. The entire process featured clear steps and standardized operations, minimizing the duration of work in the equipment's confined internal space to the greatest extent.
The newly installed filter elements exhibit excellent operating parameters, with filtration performance fully meeting the design specifications. Following the replacement, they will ensure the qualified treatment of high-concentration emulsified sour water, provide reliable protection for key downstream unit equipment, and safeguard product quality and the stability of the process chain.
The person in charge of the refinery's equipment management department highly commended this service, stating: "The professionalism, efficiency, and strong safety awareness demonstrated by the Sinokle's service team are deeply aligned with our philosophy of 'Safety First, Prevention Priority, and Lean Maintenance.' Their precise collaboration has provided strong support for the safe, stable, and long-cycle operation of our unit."
The successful completion of this filter element replacement service marks not only the conclusion of a single after-sales maintenance task but also a microcosm of the long-term collaborative win-win partnership between both parties. It highlights the value extension from "equipment supply" to "full life-cycle service support" in modern refining enterprises. Professional, timely, and reliable on-site services are deeply integrated into the production chain, continuously contributing core value to refining enterprises in achieving cost reduction, efficiency improvement, and safe, green operation.
In the future, Sinokle will continue to uphold its service philosophy of "Customer First, Safety Oriented, Technology Leading." We will deepen strategic collaboration with all partner enterprises, and leverage more sophisticated technologies, faster response capabilities, and more comprehensive solutions to support the high-quality development of China’s refining and petrochemical industry.
