Refinery Acid Residue Resource Utilization and Environmental Protection Emission Reduction Project

I. Project Background:
A refinery is facing the issue of waste acid regeneration equipment generating“ Acid residue; Dealing with difficult problems. The material has a complex composition, high viscosity, and strong corrosiveness. Traditional methods are difficult to handle, and outsourcing disposal is costly and poses environmental risks.
2. Challenges and Requirements:
Materials have strong corrosiveness, which is a huge test for equipment materials.. High viscosity and poor fluidity pose difficulties for feeding and fabric.
It is necessary to achieve solid-liquid separation, and the separated acid solution can be reused, while the solid residue meets the requirements of environmental landfill or subsequent treatment. The solution must be safe, reliable, and cost-effective.
III. Nuclear Xu Solution:
We have designed a solution to; DZYBelt press vacuum filter  Integrated processing unit as the core:
1.Strong corrosion resistance design: All components that come into contact with materials are made of Hastelloy alloy or special coatings to ensure the long-term service life of the equipment.
2.Collaborative dehydration: Combining vacuum filtration and mechanical pressing, most of the free liquid is first removed by vacuum, and then pressed by high-pressure filter belt to squeeze out the moisture between material particles, effectively treating viscous and fine materials..
3.Specialized Fabric System: Using a strong extrusion fabric applicator to ensure that viscous materials are evenly distributed on the filter belt..
4.Closed gas collection: Seal and collect the entire process, and introduce the volatile acidic gas to the treatment device..
Fourth, Application Effect and Customer Value:
1.Reduction: Acid residue volume reduction60%The abovesignificantly reduces the cost of hazardous waste disposal..
2.Resource utilization: The separated acid solution can be partially reused, reducing the consumption of fresh acid..
3.Compliance: The treated solid phase meets the "Pollution Control Standards for Landfill of Hazardous Waste", helping customers solve the problem in a compliant and environmentally friendly manner.; The old and difficult problem; Problem.
