Major technology orders for Guangxi Sun Paper pulp mill in China


S


un Paper in China has ordered cooking and fibreline equipment from Valmet, and pulp


dewatering and white liquor plant from Andritz for the new pulp mill being constructed at Beihai. Being constructed on a


greenfield site, the Guangxi Sun Paper pulp mill will eventually have capacity to produce 800,000 air dried tonnes per year of bleached hardwood kraft pulp when it is started up towards the end of 2021. The mill will be constructed in two phases over a period of about five years and will include paper making capacity of 3.5 million tonnes a year. Commenting on the project,


Yanjun Cao, vice general manager of Sun Paper, said: “Our overall target of the project is to build a world-class mill. We wanted to choose advanced and reliable technology that has little impact on the environment at the same time as it performs with high quality and efficiency and has low operating costs. We chose Valmet because they met our goals well


A Twin Wire Press of the type that ANDRITZ will supply to Guangxi Sun Paper’s new pulp mill in China


in this project. We have also had good collaboration in all previous projects.” Valmet will supply equipment and process design for continuous cooking, deknotting, screening, brown stock washing, oxygen delignification, and three-stage ECF (elementally chlorine free) bleaching. Corresponding spare parts and site services are also a part of the deal with Sun Paper. “The cooking and fibreline


will feature leading process technology, including the latest developments in our continuous cooking technology, to reach excellent efficiency in energy and raw material utilisation,” said Eva


Engelfeldt, senior sales manager in the Fiber Processing Business Unit of Valmet. “A high end-product quality with low effluent flows and high environmental performance will be secured with the latest generation of TwinRoll wash presses throughout the fibreline in combination with Valmet´s screening, oxygen and bleaching technology.” Andritz will supply a wet lap


system, a white liquor plant an evaporation plant and an ash re- crystallisation system. The wet end system will have two


production lines for a capacity of 1,120 admt/d bleached hardwood kraft pulp, each consisting of a Twin


Wire Press for pulp dewatering, a cutter-layboy and a baling line. The white liquor plant will have


capacity of 10,500 cubic metres a day and comprise recausticising equipment and a LimeKiln. The recausticising plant includes a LimeSlake slaker-classifier, three causticising tank agitators, white liquor filtration with a LimeWhite filter to maximise the white liquor quality, and efficient lime mud filtration with a LimeDry filter ensuring high lime mud dryness, which results in low heat consumption in the kiln. The new LimeKiln, with a capacity of 950 t/d, has a multifuel burner and a high-efficiency LimeCool sector cooler. The evaporation plant will have a high-concentration section for a total capacity of 1,100 t/h and a final dry solids content of 85 per cent. The ash re-crystallisation system will have an ash handling capacity of 400 t/d, to treat the ash from the electrostatic precipitator by decreasing the chloride and potassium content while recovering sodium and sulphate.


Xuong Giang in Vietnam orders a new tissue machine


A new tissue machine has been ordered from Andritz by the Xuong Giang Paper Mill in Vietnam.


The PrimeLineCompact S 1300 machine, along with a stock preparation, will have a design speed of 1,300 metres per minute and a width of 2.85 metres. It will process virgin pulp as


raw material to produce up to 54 tonnes a day of high-quality facial and toilet tissue along with


July/August 2020


ANDRITZ has supplied three of these PrimeLineCompact tissue machines to customers in Vietnam


napkins, with start-up scheduled for the fourth quarter of 2020. The stock preparation plant will be split into separate short fibre


and long fibre systems and will also include the approach flow system, fibre recovery and broke handling equipment, and pumps. The tissue machine will use a


12ft-diameter PrimeDry steel Yankee, equipped with a steam- heated hood to ensure efficient drying and energy cost savings. The Yankee will be manufactured at the Andritz facility at Foshan in China. Andritz will also supply a tailored automation system,


including PrimeControl Machine Control System, Distributed Control System and Multi-Motor Drive along with a complete Low-Voltage Motor Control Center. Detailed engineering, erection work supervision and commissioning services will also be provided.


This S 1300 is the third tissue machine to be supplied by Andritz to the Vietnamese market in recent years.
