From Chemicals to Equipment: Jusen Chem Expands into Oil Purification & Produced Water Treatment Systems

Created on 08.26
Introduction: Chemicals Alone Are Not Enough
For years, Dongying Jusen Chemical has supplied silica gel desiccants, oil bleaching sands, and oilfield production chemicals to customers around the world. Our products handle the chemical side of oil treatment — decolorizing dark diesel, breaking emulsions, removing H₂S, and treating produced water.
But chemicals need equipment to work at their best. Silica gel sand decolorization requires an effective filter tank system. Produced water treatment chemicals perform better when paired with efficient oil-water separation equipment. Waste oil regeneration depends on reliable purification machinery.
That is why we are pleased to announce a significant expansion of our capabilities: Jusen Chem now offers a curated range of oil purification and water treatment equipment, sourced from two specialized manufacturers with proven track records in the oil and gas industry.

Part I: Oil Purification Equipment — From Chongqing Kaiqian

Why this matters for our customers: This unit pairs directly with our Silica Gel Sand for oil decolorization. After the silica gel sand removes pigments and impurities from dark diesel, the skid-mounted filtration unit can further polish the oil, removing residual particles and water droplets. Together, they form a complete oil purification system from a single supplier.

3. Key Product: Vacuum Oil Purifier

Kaiqian's vacuum oil purifiers are designed for rapid removal of water, gases, impurities, and volatile substances from lubricating oil, hydraulic oil, and transformer oil. The company developed a self-excited vibration defoaming technology for vacuum oil purifiers in 2013, improving degassing efficiency and reducing oil loss.
The global explosion-proof vacuum oil purifier market reached USD 576 million in 2025 and is projected to reach USD 909 million by 2032, growing at a CAGR of 7.1%. The broader oil purification equipment market was valued at approximately USD 172–219 billion in 2025, with China accounting for roughly 28–31% of the global market share.
Applications:
  • Power industry: transformer oil purification
  • Petroleum and petrochemical: hydraulic oil, lubricating oil treatment
  • Waste oil regeneration: base oil recovery
  • Manufacturing: machine tool hydraulic oil filtration

Part II: Produced Water Treatment Equipment — From Qingdao Bylida

1. About the Manufacturer

Qingdao Bylida Environmental Technology Co., Ltd. is a high-tech enterprise specializing in the research, development, production, and EPC contracting of industrial wastewater oil removal processes and equipment. Headquartered in Qingdao West Coast New Area, the company serves the petrochemical, coal chemical, power and steel, and new energy industries.
Bylida collaborates with the Chinese Academy of Sciences (Dalian Institute of Chemical Physics and Ningbo Institute of Materials), China University of Petroleum, Xi'an Shiyou University, Chang'an University, and Shandong University of Science and Technology on joint research and development. The company has been granted multiple national invention patents for its physical oil removal technologies, achieving high-efficiency precision separation of oil, water, and solids.
Bylida's core products include:
  • Tank-in-Tank integrated oil-water separation system
  • Corrugated plate interceptor (CPI) components
  • Micro-bubble cyclone oil remover
  • Dissolved air flotation (DAF) units
  • WYS series horizontal oil-water separators
  • ZJYS series fine oil-water separators (for emulsified oil <10 μm)
  • Vehicle-mounted integrated oil-water separation units

2. The Problem Bylida Solves

China's oilfields are entering the later stages of production. Low-permeability fields require large volumes of injected water to maintain pressure, and the water cut in produced crude oil increases year by year. Traditional treatment processes — "two-stage sedimentation + two-stage filtration" — can no longer meet reinjection water quality standards. Equipment capacity drops, sedimentation times become excessive, and effluent quality fails to meet specifications.
For ASP (alkali-surfactant-polymer) flooding produced water, the challenges are even greater: high viscosity, high oil-displacing agent content, high alkalinity, high salinity, fine particles, and difficult oil-water sedimentation separation.
Bylida's technology addresses these challenges through a combination of gravity separation, coalescence separation, and new material demulsification technologies.

3. Key Technology: Tank-in-Tank

The Tank-in-Tank system integrates wastewater regulation, homogenization, and oil removal into a single unit. Produced water enters a multi-tube hydraulic cyclone separator inside the tank, where centrifugal force separates oil, water, and sludge into three phases. The separated oil rises to the top of the inner tank, where an automatic oil skimming device transfers it to an external oil collection tank.
Key advantages:
  • Compact footprint — integrates multiple functions in one vessel
  • Physical separation — no chemicals required for the separation stage
  • High efficiency — effective for both free oil and dispersed oil
  • Automatic operation — reduces labor requirements

4. Key Technology: ZJYS Fine Oil-Water Separator

The ZJYS series is Bylida's upgraded fine oil-water separator, designed as a purely physical oil removal device that integrates cyclone separation, coalescence, and demulsification. It is specifically engineered to break and separate emulsified oil droplets smaller than 10 μm.
Emulsified oil is a persistent challenge in industrial wastewater treatment. Unlike free oil, which rises naturally, emulsified oil droplets remain stably suspended in water due to surface-active agents and fine particles. Conventional gravity separation cannot remove them effectively. The ZJYS series uses demulsification coalescence materials to destabilize the emulsion, causing oil droplets to merge into larger droplets that can then be separated by gravity.

Part III: Market Context — Why Equipment Matters Now

1. Produced Water Treatment Market Growth

The global produced water treatment systems market was valued at approximately USD 8.28 billion in 2025 and is projected to reach USD 13 billion by 2033, growing at a CAGR of 5.8%. Other estimates place the 2025 market between USD 5.4 billion and USD 9.94 billion, with growth rates ranging from 5% to 10%.
The U.S. petroleum industry alone generates over 24 billion barrels of produced water annually — the largest volume of unwanted byproduct in oil and gas production. As mature fields produce more water per barrel of oil, the demand for efficient, compact treatment equipment continues to rise.

2. Oil Purification Equipment Market Growth

The global oil purification equipment market was valued at USD 172–219 billion in 2025, with China accounting for approximately 28–31% of global demand. The market is growing at 6–7% annually, driven by stricter environmental regulations, increasing waste oil volumes, and the need for energy-efficient purification solutions.
The explosion-proof vacuum oil purifier segment alone reached USD 576 million in 2025, with a projected CAGR of 7.1% through 2032.
Why this matters: As regulations tighten and operating costs rise, oilfield operators and refiners need both effective chemicals and reliable equipment. Buying from a single supplier reduces integration risk, simplifies logistics, and ensures that chemicals and equipment are designed to work together.
