Introduction：

BZ Series Hi-gee Rotating Zigzag Bed (RZB) is a kind of new-type high-efficiency rectification equipment, which consists of mono- or multi- high-speed rotors. Gas and liquid flow zigzag through the rotors counter-currently and carry out mass transfer. Unlike traditional rectification, no bubbles exist in supergravity rectification, which magnificently improves the separation capability. The separation capability of RZB with a height of 1.2 meters can be comparable to that of a conventional packed towers and plate tower with a height of 15 meters, which is a major breakthrough. Appraised by the national-level expert group, RZB has reached the international advanced level.

Main parameter

Target	ethanol and other solvent
Minimum inlet concentration	10%
Max outlet concentration	99.5%
Running consumption	steam

Advantages

Our Advantages

1.Centrifugal force reaches 300–500 times Earth's gravity, expanding the gas-liquid contact area tenfold. A 1.2-meter-high unit replaces traditional 15-meter distillation towers.

2.Purifies solvents like ethanol and methanol to 99.5–99.9% purity in a single pass, with residual waste concentration ≤0.5%.

Efficiency Leap

1.Reduces steam consumption by 30–50% and footprint by 80%.

2.Constructed with corrosion-resistant materials (e.g., S31603, titanium alloy), suitable for highly corrosive solvents like DMSO and DMF.

Energy-Saving & Compact Design

1.Supports semi-automatic or fully automatic control, with 10-minute quick start/stop and remote monitoring.

2.Annual maintenance costs reduced by 60%, requiring only periodic seal replacements.

Intelligent Operation & Maintenance

Application

Hi-gee RZB has been widely used in the recovery of organic solvents, separation and purification. The organic solvents include ethanol, methanol, acetone, ethyl acetate, acetonitrile, THF, dichloromethane, DMF, DMSO, toluene, isopropanol, tert-butanol, etc. So far, there are more than 100 sets of equipments that have been applied to the industries of pharmaceutical material, pharmaceutical intermediate, fine chemicals, bio-diesel, and environment protection industry and other fields in China.

Application

Pharmaceutical Case

A pharmaceutical company achieved 99.9% DMSO purification (from 70% initial concentration), saving over ¥1 million annually.

Environmental Results

Achieves 98.2% dichloromethane recovery, meeting EU emission standards.

New Energy Efficiency

95% methanol recovery in biodiesel production, with 40% lower energy consumption per ton.
