China to build world's largest straw pulp alkali recovery system

China Energy Recovery, Inc., a leader in the waste heat energy recovery sector of the alternative energy industry, announced that it has executed contracts for designing and manufacturing the world’s largest straw pulp alkali recovery system in alliance with CMIIC Engineering & Construction Corporation. The recovery system is a key part of the Shandong Hai River Basin Pollution Control Project sponsored by the Asian Development Bank. The total project cost is estimated to be RMB95 million (approximately US$13.9 million based on the exchange rate as of date of this press release date), of which RMB79 million (approximately US$11.6 million) represents the estimated cost for the alkali recovery system that CER will design and manufacture leveraging its own technology.
The system is to be built for Shandong Tralin Group (“Tralin”), one of the top paper manufacturers in China. The CER technology will treat the toxic residual black liquor generated from the pulp making process to create cleaner discharge. The system is designed to process 1,200 tons of black liquor per day and expected to enable Tralin to meet the government mandate on minimizing pollutant discharge.
The system is also designed to generate 145 tons of steam per hour. This is equivalent to nearly 12MW of heat energy generation capacity and expected to enable Tralin to reduce the cost of purchasing steam from outside vendors needed to power its paper making facility. Additionally, the system is expected to recover 195 tons of alkali per day, which can be reused in the pulp making process, thus further reducing material costs and bringing multiple benefits to Tralin.
