# SDHT: The 700,000-ton chemical wood pulp project has started commissioning and trial operation

According to the announcement from Huatai Co., Ltd. (600308.SH), the construction of the company's 700,000-ton chemical wood pulp project production line has been completed, and the device process has been fully connected, achieving successful commissioning. The company will further optimize relevant process parameters based on the operating conditions of the production equipment to ensure that production capacity is reached as soon as possible.

The 700,000-ton chemical wood pulp project uses the world's advanced dual-tower Steam/liquorPhase continuous cooking, elemental chlorine-free (ECF) bleaching technology, and high-temperature, high-pressure, efficient alkali recovery system from Finland's Valmet company, including supporting lime regeneration kiln, ANDRITZ company's preparation system, and German BOGE centrifugal air compressor, among others. After the completion and commissioning of the 700,000-ton chemical wood pulp project, it will not only enhance the scale, cost, and quality advantages of the company's pulp products but also meet the company's own finished product recycling and further extend upstream products. This will further ensure raw material supply, improve the competitiveness of the company's products, and have a positive impact on the company's high-quality development
