Haosheng Chemical (Shandong) Co., Ltd. is a technology research and development enterprise dedicated to the research, development, production and sales of isooctyl nitrate (diesel cetane number improver), diesel anti-wear agent, aluminum sulfate, polyacrylamide dry powder, polypropylene amide lotion, refinery additives (including product antioxidant, fuel purification synergist, corrosion inhibitor, slurry scale inhibitor, demulsifier, pour point depressant, desulfurizer, decalcifying agent, defoamer), oilfield additives (including product bioactive nano displacement modifier, bioactive viscosity reducer, environmental protection surfactant) and other series of products. The company always takes new technology and new achievements as the guide, and relies on CNPC University (East China), Shandong Institute of Petroleum and Chemical Engineering, Qingdao University of Science and Technology advanced scientific research force; The establishment team of the company consists of professional management and production teams from Dongying Liyang Chemical Co., Ltd. and Shandong Yipeng Energy Development Co., Ltd. Due to the constraints of the old factory area on the development of Shandong Yipeng Company, in order to make the company bigger and stronger in the petrochemical industry, we rely on the complete industrial and management system of Dongying Liyang Chemical and Shandong Yipeng Energy (Dongying Liyang Chemical is a national high-tech enterprise with rich process technology foundation in the fine chemical industry, rich experience in product quality control, and ISO9001 quality management system in chemical production) ISO14001 environmental management system and ISO45001 occupational health and safety management system certification, all product quality has passed SGS certification, and products are exported to the Middle East, Europe, America, Southeast Asia, and West Africa. Haosheng Chemical (Shandong) Co., Ltd. was established with an investment of 347 million yuan in the Blue Economy Industrial Park in Hekou District, Dongying City, engaged in the research and market operation of petrochemical additives and catalysts.
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.
