Advantages
The core advantage of this process lies in combining efficient refrigeration with deep separation. The cascade of propane precooling and mixed refrigerant deep cooling achieves high thermal curve matching, significantly reducing liquefaction energy consumption. Through heavy hydrocarbon scrubbing technology, high-value components such as ethane and propane can be efficiently recovered (recovery rate >90%), significantly enhancing project economics. Simultaneously, deep impurity removal ensures the purity of LNG products and long-term stable operation of the equipment, making it particularly suitable for processing rich gas resources.
