60 t/d Two-Effect Zinc Sulfate Evaporation & Crystallization System Project Launched in Malaysia

2026-02-24

A 60 tonnes per day (6 t/h evaporation capacity) two-effect countercurrent zinc sulfate evaporation and crystallization system project is set to upgrade the client’s zinc sulfate manufacturing process in Malaysia, phasing out the original batch-type single-kettle evaporation and crystallization process.

Sichuan Shuotai Saipu Environmental Protection Technology Co., Ltd., a subsidiary of SDN Group (Sidaneng), undertakes core process design and key equipment integration for the whole facility.

The continuous automatic system targets multiple key objectives:

First, realize continuous production and higher capacity. Transforming intermittent operation into stable automated continuous manufacturing, the plant will deliver 2.5 tonnes per hour of high-quality monohydrate zinc sulfate ((ZnSO_4·H_2O)).

Second, cut energy and operational expenditure. The two-effect countercurrent process greatly reduces steam consumption. Automated operation further lowers labour requirements.

Third, improve finished product quality. Adopting advanced high-temperature evaporation and crystallization technology for zinc sulfate, the system enables precise crystallization control to produce premium-grade monohydrate zinc sulfate with uniform particle size and high purity.

Fourth, achieve internal resource recycling. Condensed water generated from evaporation will be fully recycled for upstream washing procedures, facilitating water circulation inside the production line and satisfying clean production and environmental standards.
