Research and Experiments of Preparing Construction Clay from Soda Residue;

Study on optimum burning temperature of white cement by soda residue;

Experimental study on strength characteristics of soda residue with high water content;

Study on the process of producing sodium percarbonate through byproduct of hydrazine hydrate-caustic sludge;

A catalyst was applied in the oxidation process to remove sulfides from sulfur-containing caustic sludge produced in gasoline and LPG desulfurization operations.

Take example for plants protecting engineer of muddy sea wall in Tianjin,using caustic sludge and brackish dredged sediment as medium,salt-tolerance plants and halophyte were planted after scientific manufacture and desalting treatment.

Developing sodium percarbonate with by-product alkali residue of hydrazine hydrate;

Discussion on comprehensive treatment process of carbide slag and alkali residue

Alkali residue has not the apparent stimulation effect on the activity of fly ash,and the strength of specimens decreases with the increase of (carbonate residue/fly ash)ratio.

On-line Detection and Control System for Alkali Waste pH Value;

Comprehensive treating technology of carbide slag and alkali waste

The heavy waste oil formed by the refinery wastewater treatment was separated by a two-step process based on the physical and chemical separation mechanism using scavenging agent composed of flocculant containing multi-valence metal cations, acidic water and alkali waste from the gasoline/diesel oil treating units.
