Import Bitumen Or Asphalt Oxidation Unit — Buy in Bulk from Supplier in China

The bitumen oxidation unit from Sun Faith Engineering Ltd., based in Chongqing, processes vacuum residue into oxidised asphalt through controlled air blowing within a vertical oxidation tower. Feedstock enters after heat exchange, then reacts with compressed air introduced at the tower base, while fresh water sprays from the top to cap gaseous phase temperature at 160 °C. The degree of asphalt hardness, ranging from penetration grade 60 to 120, is governed by three variables: vacuum distillation extraction level, oxidation duration, and air blowing quantity.

The system integrates several auxiliary loops. Tail gas exits the tower top into a saturator where water contact cools the stream and separates dirty oil; residual gas then passes through a water-sealed tank before incineration, with recovered heat recycled to pre-heat feedstock entering the vacuum tower. A separate diesel circulation loop, comprising a circulating pump, asphalt-diesel heat exchanger, and diesel cooler, raises diesel temperature from 65 °C to 140 °C then returns it to 65 °C using circulating water. The saturator, residual oil tank, and diesel tank share a common casing, and the entire unit is shipped in a wooden case.

This oxidation unit suits refineries and asphalt blending terminals that need to convert vacuum residue into roofing-grade oxidised bitumen or harder paving binders. Buyers should confirm whether Sun Faith Engineering Ltd. provides installation supervision, commissioning support, and spare parts for the incinerator burner and diesel cooler. Given the zero response rate recorded, direct enquiry is essential to clarify warranty terms, delivery Incoterms, and whether the quoted scope includes instrumentation and control systems.

Sun Faith Engineering Ltd. is registered at 10-7, Songqiao Building, Longxi Yubei District, Chongqing 400040, China. The supplier holds an imported tier classification and a harbor trust tier, which indicates a basic marketplace presence without additional third-party verification. The response rate stands at 0.00 percent with zero average response hours, so no historical engagement data is available to assess communication reliability.

The listing presents a complete process description for the bitumen oxidation unit but omits manufacturing standards, pressure vessel codes, material certificates, and after-sales support scope. No workforce size, annual turnover, year of establishment, or client references are stated. Buyers should request ASME or GB pressure vessel certification, welder qualifications, and past project references before committing.
