ZJS provides petroleum sulfonate technology and plant engineering for WPS and HAS oilfield surfactants, covering SO₃ falling film sulfonation, equipment manufacturing, commissioning and technical service.
Petroleum sulfonate is an anionic surfactant produced from petroleum distillate or suitable petroleum fractions. In ZJS technology, the raw material is sulfonated with sulfur trioxide in a falling film sulfonator, followed by controlled neutralization and downstream processing to obtain petroleum sulfonate products for oilfield and industrial applications.
Weighted petroleum sulfonate (WPS) is mainly used as an enhanced oil recovery chemical. When combined with alkali and polymer in a three-component oil displacement system, petroleum sulfonate can help reduce oil-water interfacial tension and improve the separation and mobilization of crude oil attached to reservoir rock.
Heavy alkylbenzene sulfonate (HAS) can be produced from heavy alkylbenzene and used in enhanced oil recovery, lubricant additives and related industrial fields. ZJS provides process development, raw material formulation support, sulfonation plant design, key equipment manufacturing and commissioning services for WPS/HAS production.
Petroleum Sulfonate for EOR
Heavy Alkylbenzene Sulfonate
Falling Film Sulfonation
The WPS/HAS process begins with petroleum distillate or heavy alkylbenzene raw material and sulfur trioxide. After SO₃ falling film sulfonation, the sulfonated intermediate is neutralized and processed into petroleum sulfonate products. Tail gas treatment and by-product handling are integrated into the process to support stable and safer plant operation.

Chemical enhanced oil recovery uses surfactants to reduce interfacial tension between crude oil and water, helping mobilize residual oil that remains after primary and secondary recovery. Petroleum sulfonate can be formulated with alkali and polymer in an ASP system. The surfactant helps lower oil-water interfacial tension, while alkali and polymer contribute to system performance depending on reservoir conditions, crude oil properties and injection strategy.
ZJS combines petroleum sulfonate R&D, falling film sulfonation engineering and large-scale plant experience to support oilfield surfactant production from raw material evaluation to plant start-up.
ZJS has carried out long-term research and development in petroleum sulfonate production technology, raw material formulation and oil displacement surfactant systems.
The technology supports WPS from petroleum distillate and HAS from heavy alkylbenzene, covering enhanced oil recovery, lubricant additive and industrial sulfonate applications.
ZJS has designed and manufactured petroleum sulfonate units using multi-tube falling film sulfonation reactors, including large-scale reactor configurations for oilfield production bases.
ZJS provides process design, equipment manufacturing, installation guidance, commissioning, technical training, plant upgrading and technical consultation for petroleum sulfonate projects.
Petroleum sulfonate products can be designed for oilfield chemical systems, lubricant additive applications and industrial surfactant use, depending on feedstock, sulfonation degree, neutralization system and final specification.
Weighted petroleum sulfonate (WPS) is used as an oil recovery surfactant in chemical EOR and ASP flooding systems, helping reduce interfacial tension and improve crude oil mobilization.
Heavy alkylbenzene sulfonate (HAS) can be used in enhanced oil recovery systems and as a lubricant additive where oil solubility, emulsification or corrosion protection properties are required.
Petroleum sulfonate can be combined with alkali, polymer or other surfactants according to reservoir salinity, temperature, crude oil composition and target interfacial tension.
ZJS can support product development, raw material evaluation, pilot testing and scale-up before investment in a commercial petroleum sulfonate production line.
A complete petroleum sulfonate production line can be configured around the selected raw material, target product, production capacity, neutralization route, environmental requirements and automation level.
Storage, heating, filtration and metering systems for petroleum distillate, heavy alkylbenzene or other selected feedstocks.
Multi-tube falling film sulfonator designed for continuous contact between petroleum feedstock and SO₃ gas under controlled temperature and residence time.
Neutralization reactors, pumps, mixing systems and pH control configured according to WPS or HAS product specification.
Tail gas absorption and treatment systems for SO₂/SO₃-containing gas streams, designed according to plant capacity and environmental requirements.
DCS/PLC, MCC, SIS, ESD, alarms, interlocks and process monitoring can be configured for stable operation and safer plant control.
Available in multiple capacity ranges to match your production requirements, from pilot-scale R&D units to full industrial production lines.
