Technical principle and process
The design of a unique heat exchange element structure is placed inside the isothermal conversion reactor by using the technology of double tubeplate structure, double sleeve, full radial and radial distributor, and the use of boiling water phase transition heat absorption, timely and efficiently remove the reaction heat, to achieve isothermal, low temperature and constant temperature reaction. The catalyst has a long service cycle, the depth transformation of one furnace and one section, the reaction efficiency is high, the reactor resistance is low, and it is easy to scale up. Secondary production medium pressure steam, high heat recovery efficiency, short system flow, low resistance.
Technical index

Technical functional characteristics
1, can achieve a furnace a section depth transformation, high reaction efficiency;
2, the use of boiling water phase transition heat absorption, timely and efficient removal of reaction heat.
Application case
Isothermal conversion project of space furnace gas and hydrogen analytical gas mixture to synthetic ammonia: The isothermal conversion device is deployed in 400,000 tons/year of synthetic ammonia, 35,000 cubic meters/hour of hydrogen gas purification and ammonia synthesis device.
After completion of construction, compared with the traditional process system, the resistance will be reduced by 0.3 mpa, saving 7,264 tons of standard coal per year and reducing CO220,000 tons per year. The comprehensive annual economic benefit of the project is 18.05 million yuan, and the payback period is 21 months.
The industry is expected to reach 33% by 2025. It can save 100,000 tons of standard coal and reduce 277,000 tons of CO2 annually.
