Radial Adiabatic (Isothermal) Conversion Technology
Never stop on the development path of pursuing green chemical industry
Innovation
We adopt the independently developed radial gas distribution technology to achieve adiabatic (isothermal) conversion reactions, effectively reducing the resistance of the conversion system.
Technical Advantages
01
Low Resistance in Radial Adiabatic (Isothermal) Converter: ≤30kPa;
02
The adiabatic conversion reacts in high temperature, with fast reaction rate High conversion rate of HCN, COS, carbonyl compounds, and high-grade thermal energy recovery rate;
03
The isothermal conversion reaction has a wide temperature adjustment range High CO conversion rate, and low CO equilibrium concentration;
04
Short equipment list, short process flow, easy for operation medium-pressure superheated (saturated) steam can be produced as a byproduct;
05
The combined thermal insulation (isothermal) conversion technology adapts well to various scenarios. The system is safe, reliable and cost-savings, with low energy consumption, and considerable amount of thermal energy recovery.

Applications
September 2022
The GC-type radial adiabatic converter technology was applied to a 1.8 million-ton methanol plant, reducing the converter's resistance by ≤12.5kPa, with an average temperature difference of 3℃ and a maximum temperature difference of 5.5℃. The operating parameters have reached the international advanced level.
