FULL CIRCULATION PROCESS BASED ON HOU'S PROCESS FOR SODA MANUFACTURE

摘要

Disclosed in the present invention is a full circulation process based on Hou's process for soda manufacture, which comprises: a. preparing a raw brine for manufacturing soda by solution mining; b. obtaining hydrogen sulfide and biogas by utilizing microbial resource in the brine; c. evaporating and concentrating thin alkali liquid by utilizing natural energy; d. producing various types of products by combining Trona process and chemical combination process; e. producing subsidiary products by combining coal chemical industry deep processing and soda-making process; and f. producing series of products by combining an electrolytic process and a chemical combination process. The provided process is used to the full circulation process based on Hou's process for soda manufacture. The provided process has the beneficial effects that wasted or concealed natural soda resources are explored for raw material supply, biological energy and natural energy are comprehensively utilized for energy utilization, potential of coal chemical industry deep processing is developed and an activated carbon purification technology is applied to low-carbon economy so as to serve the purposes of energy conservation and environmental friendliness so that technologies in various fields are closely integrated with the soda-manufacturing process, thus fundamentally realizing the full circulation and greatly lowering the cost.
