Let’s give praise and encouragement to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Great Development in Chemical Engineering Equipment】A continuously updated summary post is available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** On December 18th, within the “China Coal 100,000-ton Liquid Sunlight Project”, the world’s largest multi-functional hydrogen production BOP system with a capacity of 9,600 Nm³/h, supplied by Sany Hydrogen Energy, was successfully put into operation. The achievement of this key milestone marks the project’s entry into a new phase of equipment delivery and installation. The world’s first industrial-scale demonstration project for liquid sunlight: China Coal Enerchemical’s 100,000-ton per year liquid sunlight project, powered by green energy – 400MW of photovoltaic capacity and 225MW of wind power. Hydrogen production capacity: 21,000 tons of hydrogen per year. Downstream applications: 100,000 tons of methanol per year. Three groundbreaking technologies: For the first time, it integrates the entire chain from wind and solar green energy to green hydrogen and carbon recycling, creating a system for the utilization of millions of tons of carbon dioxide; it also features the world’s largest facility for converting green hydrogen into methanol. The world’s largest hydrogen production BOP system with a capacity of 9600 Nm³/h has been designed for use in liquid solar energy applications. For China Coal’s 100,000-ton liquid solar energy project, Sany Hydrogen Energy provides 8 alkaline electrolyzers with a capacity of 1200 Nm³/h (using the volume method), along with 2 gas-liquid separation systems capable of handling 4800 Nm³/h each, and 1 hydrogen purification system with a capacity of 9600 Nm³/h – all of which are essential components for this system. This system is Sany Hydrogen Energy’s newly developed flagship product of the second generation of hydrogen production equipment, featuring six key improvements: 1. Enhanced adaptability: It adopts a one-to-one alkaline solution variable-frequency circulation process as well as an intelligent control system for hydrogen purification and regeneration gas; the load range of this integrated system is 10%-110% ； 2. The system is more secure: An oxygen hydrogen analyzer is installed at the oxygen-side outlet of the electrolyzer; analysis instruments, pressure gauges, and level gauges are installed at the gas-liquid separation and purification outlets; a three-out-of-two interlock system is in place, as well as interlocks for over-temperature and over-pressure conditions, and measures to prevent backflow of gases, all of which help ensure the safety of the system ； 3. Easier to operate: Adopting a modular design concept and following ergonomic principles, the gas-liquid separation and purification systems are equipped with ladders, making maintenance, repair, and operation much more convenient ； 4. Higher degree of automation: It features functions such as automatic water replenishment, automatic sampling, automatic nitrogen filling, and intelligent sludge removal ； 5. The system is more efficient: it adapts to the fluctuations in renewable energy sources, intelligently matches the number of electrolyzers in operation with the hydrogen production volume, features multi-stage cooling and adaptive heat management, as well as purification, deoxygenation, preheating, and recycling processes, thereby reducing overall energy consumption. 6. The system is more environmentally friendly: environmental protection is given top priority; gas-liquid separation ensures complete recovery of the alkaline solution, resulting in no alkaline solution emissions from the entire system.
