Traditional HPF desulfurization processes generally suffer from issues such as large amounts of waste liquid, high disposal costs, high environmental risks, waste of sulfur resources, poor desulfurization efficiency, and easy clogging and corrosion of equipment. Inadequate improvements to traditional manufacturing processes result in high costs for enterprises in pollution control and low overall profits. GLT’s “zero waste liquid” desulfurization technology relies on the comprehensive upgrade of four core systems to address the challenges associated with desulfurization at its root, achieving both zero waste liquid discharge and high-purity sulfur recovery – thus helping enterprises to operate in compliance, maintain stable production, and reduce costs while increasing profits. 01 Traditional desulfurization issues ❌ Environmental pressures: High volume of waste liquid, high disposal costs, and persistent risks from environmental inspections. ❌ Resource losses: Low sulfur recovery rate, resulting in the loss of usable resources; efforts to treat pollution incur costs without any returns. ❌ Unstable production: Accumulation of by-products and tar, equipment corrosion that leads to blockages, and frequent shutdowns that reduce production. 02 Four core systems for a comprehensive solution to these problems 🔧 Adaptive upgrades | Upgrades can be carried out without interrupting production, ensuring stable output and efficiency. Upgrades are possible without any loss in production capacity. The sulfur recovery rate is increased to 99%+, preventing the formation of by-products at the source, which addresses issues such as equipment corrosion and tower blockages, resulting in more stable system operation. 💰 Sulfur recycling system | Saves energy and reduces consumption, turning waste into treasure. Steam consumption per ton of sulfur is ≤1 ton, resulting in a significant reduction in energy use. Achieve a stable output of 90%+ high-purity sulfur, turning environmental protection measures into sources of additional revenue. 💧 Oil-removal purification system | Precise impurity removal for a clean circulation. It effectively separates impurities such as tar and slag, keeping the circulating fluid clean, stabilizing the desulfurization process, and addressing issues like weak sulfur foam, excessive foaming, and high viscosity of the desulfurization liquid. ♻️ Material balance system | Dynamic balance control to ensure zero waste discharge. It enables targeted separation of waste salts and impurities, maintains dynamic balance of materials, completely solves the problem of waste liquid accumulation, achieves zero waste discharge throughout the process, and eliminates the burden associated with waste liquid disposal. 03 Core Advantages: Environmental protection and cost efficiency – a win-win situation ✅ No compliance issues: Zero waste discharge, meeting even the strictest environmental standards, thus avoiding regulatory risks ✅ Cost reduction and revenue increase: Low energy consumption, high recovery rates, and income generation from sulfur, all contributing to reduced overall operating costs ✅ Continuous stable production: No blockages in the towers, low corrosion, no need for shutdowns for renovations, ensuring stable production levels ✅ Long-term reliability: Suitable for various coking conditions, stable operation, and no need for frequent technical upgrades. In the context of the dual-carbon goals, it is essential for coking enterprises to pursue green transformation as well as cost reduction and efficiency improvement. GLT’s “zero waste liquid” desulfurization technology eliminates the drawbacks of traditional desulfurization methods through advanced processes, enabling enterprises to achieve sustainable, low-carbon, and high-quality development!
