The Biodegradable and Recyclable Center was informed that on February 18, Xinjiang Lanshan Tunhe Energy Co.
China Chengda is one of the first batch of units in the country with comprehensive Grade A qualifications, and is a national-level comprehensive large-scale engineering company with general project contracting
The third-phase BDO and second-phase PTMEG project general contracting projects signed this time are in line with Lanshan Tunhe's efforts to build "Qitai Fine Chemical Industrial Park" and "Changji Bio-New Material Science and Technology Industrial Park", and develop two industrial clusters.
In January, the Department of Ecology and Environment of Xinjiang Uygur Autonomous Region released the environmental impact assessment announcement of the third phase of Xinjiang Lanshan Tunhe Energy Co.
It is reported that Lanshan Tunhe BDO has put into production 204,000 tons, PBAT has put into operation 130,000 tons, and another 240,000 tons of PBAT project is under construction
Project Status
Project StatusConstruction site: It is located in the factory area of Lanshan Tunhe Energy Co.
Type of construction: Expansion
Construction period: 2 years
Total construction investment: 1,962.
The 1.
Construction content: It is proposed to build a 104,000 t/a production line (single BYD reactor, crude BYD storage tank and BYD storage tank in the intermediate tank area connected with the second phase, and 1,4-butanediol (BDO) product tank in the intermediate tank area 2×2000m³, adding 400m³ of butanol storage tank), supporting the construction of a set of 12,000Nm³/h hydrogen production unit with a design capacity of 40,000 t/a acetylene generation unit; 230,000 t/a (37wt%) formaldehyde production unit (newly built formaldehyde production unit) Storage tank 3×1000m³); new 120m³ sewage treatment station and its deodorization facilities; supporting calcium carbide crushing system; newly established carbon material drying kiln and conveying system
