Recently, the world's first project to convert coke oven gas into liquefied natural gas (LNG) has successfully completed its trial production phase. The project, titled "120 million m³/year Coke Oven Gas LNG Project of Inner Mongolia Hengkun Chemical Co., Ltd., affiliated with Xinkuang Inner Mongolia Energy Co., Ltd.," marks a major breakthrough in the field of LNG technology derived from coke oven gas. This pioneering initiative utilizes a mixed refrigerant process for cryogenic liquefaction, turning previously wasted byproducts into valuable energy resources. As part of this project, the Institute of Physics and Chemistry, Chinese Academy of Sciences, was responsible for the design and technical support of the mixed refrigerant refrigeration system. The process begins with the compression and pretreatment of coke oven gas, followed by fine desulfurization. After that, the gas undergoes methanation, where carbon monoxide and carbon dioxide are converted into methane. The heat generated during this reaction is recovered and used as steam for industrial purposes. The resulting methane-rich gas then goes through cryogenic liquefaction, producing LNG and hydrogen-rich byproducts. Inner Mongolia Hengkun Chemical Co., Ltd. is part of a larger development plan that includes a 5 million ton/year rammed coke project, a 600,000 ton/year coal tar deep-processing facility, and multiple coke oven gas LNG projects. The first phase of the coking park is already operational, producing 1.3 million tons of rammed coke and 120 million cubic meters of LNG annually. This project significantly enhances the utilization of natural gas from coke oven gas, increasing LNG production by approximately 30%. It also reduces annual exhaust emissions by 3.2 billion standard cubic meters and saves about 100,000 tons of standard coal. These achievements contribute greatly to energy conservation, emission reduction, and the development of a circular economy. The project plays a vital role in promoting a resource-saving and environmentally friendly society. The research team at the Key Laboratory of Cryogenic Engineering, Chinese Academy of Sciences, has long focused on the comprehensive utilization of various waste gases, including oxygen-containing coalbed gas, coke oven gas, and synthetic ammonia vent gases. By integrating cryogenic technologies with chemical processes, they have pioneered new methods to turn waste into valuable resources and promote green energy development. Their work includes the development of an energy-free ammonia recovery process, the comprehensive use of coke oven gas, and the liquefaction and separation of oxygenated coalbed methane. These technologies have been widely applied in both experimental and industrial settings, advancing the process from research to large-scale implementation.

The world's first coke oven gas liquefied natural gas project trial production
There are two main types of fountain pumps: centrifugal pumps and submersible pumps. Centrifugal pumps are suitable for fountain designs that require uniform head, while submersible pumps are suitable for fountain designs that require flexible adjustment of head. Submersible pumps are superior to centrifugal pumps in terms of flexibility, but centrifugal pumps perform better in terms of performance, efficiency, and maintenance rate. When choosing a fountain pump, you need to consider the following points:
Flow and head: According to the scale and design requirements of the fountain, choose the appropriate pump flow and head to ensure that the pump can provide sufficient water volume and pressure.
Power and efficiency: Choose an energy-efficient pump to reduce operating costs.
Material and durability: Choose a pump made of corrosion-resistant and rust-proof materials to ensure long-term stable operation.
Noise level: Choose a pump with lower noise to avoid interference with the surrounding environment and spectators.
