Haosheng Chemical (Shandong) Co., Ltd. is located in Dongying City, Shandong Province, a beautiful harbor and petrochemical city. It is a technology-based enterprise dedicated to the research, development, production, and service of various additives and auxiliaries for oilfield drilling, production, and refining. With over two decades of professional and persistent experience, it has built a high-quality management team and a range of superior technical products. These products are widely used by PetroChina, Sinopec, CNOOC, and local petrochemical enterprises. The company has established technical cooperation and product research and development partnerships with a number of well-known domestic universities and research institutions, such as Dalian University of Technology, China University of Petroleum, Southwest Petroleum University, and Qingdao University of Science and Technology. It is committed to establishing technical and product support service cooperation with multiple domestic oilfield service companies or teams. This has gradually formed the company's unique product and service advantages, creating a virtuous cycle economy characterized by strong product targeting, outstanding effectiveness, and significant benefits. The company adheres to its corporate culture and core development philosophy, which have been formed over many years. It persists in taking the green, environmental protection, and energy-saving technological path, fulfilling its social responsibilities diligently; creating value for customers, providing them with quality services, and achieving mutual benefit and win-win results; building an enterprise platform to maximize the talents and abilities of everyone; and realizing harmonious development and maximizing the interests of the enterprise, society, customers, and employees. The company continuously strives to improve its internal capabilities and self-improvement. In terms of production, it has obtained ISO9001 quality management system, ISO14001 environmental management system, and ISO45001 occupational health and safety management system certifications, as well as SGS certification for product quality. It has established independent or cooperative technical testing centers and product research and development centers, achieving the goal of producing one generation, researching and developing another, and reserving a third. In addition to supplying domestic oilfield and refining enterprises, the company's products are also exported to Europe, North America, Africa, Asia, and other countries and regions, receiving high praise and accolades from a wide range of customers.
Haosheng Chemical's diesel additives include cetane improvers, anti-wear agents, pour point depressants, etc., to optimize diesel performance. Cetane improvers (isooctyl nitrate) enhance combustion efficiency, reduce cold-start noise, and lower emissions; anti-wear agents improve lubricity for low-sulfur diesel and protect fuel systems; pour point depressants enhance low-temperature flow by inhibiting wax crystal formation. Compliant with China VI standards, these products are suitable for refinery blending and fuel upgrading, with dosage rates of 0.1‰-2‰, significantly improving diesel quality and economic benefits.
Our oilfield chemicals include drilling fluid additives, polyacrylamide (PAM) for enhanced oil recovery, suitable for high-temperature, high-salinity reservoirs. PAM powder/emulsion improves crude recovery and reduces friction; corrosion inhibitors protect downhole equipment; defoamers control foam height in delayed coking processes. With temperature resistance up to 120°C and excellent salt tolerance, these products support tertiary recovery technologies, helping oilfield operators improve extraction efficiency and extend equipment lifespan.
Refining additives include FCC antifoulants, metal passivators, and sulfur transfer agents to address coking and corrosion. Antifoulants disperse catalyst fines, extending heat exchanger cycles; passivators (containing antimony/lanthanum) neutralize heavy metal toxicity to protect catalyst activity; sulfur transfer agents reduce gasoline sulfur by over 30%. Suitable for heavy oil processing with dosages of 50-300ppm, they can increase light oil yield by 2-5%, supporting refineries in achieving extended operation cycles and cleaner production.
For petrochemical wastewater, we offer PAM flocculants, corrosion inhibitors, etc. Cationic PAM achieves ≥80% COD removal in sludge dewatering; neutralizing corrosion inhibitors maintain sulfur-containing wastewater pH at 6.5-7.5 with ≥90% corrosion inhibition; iron sulfide cleaners passivate deposits to prevent spontaneous combustion during maintenance. Compliant with environmental standards, these products effectively reduce suspended solids and heavy metals in refinery and oilfield wastewater, ensuring compliant discharge.
