Black water sedimentation problem in the water-coal slurry gas generation process!

The specific formula is usually kept confidential, but it is possible to contact the manufacturer. It’s available at the Weihe Fertilizer Factory.

The main components of dispersants and flocculants are usually kept secret by the manufacturers from their customers; the main manufacturers include those in Tianjin and Nanjing Kaiguang

A dispersant still needs to be added. There’s nothing mysterious about coagulants; it’s just a few migrant workers who handle their production.

1. The active ingredients of the additive are carboxymethyl cellulose, ethyl cellulose, and other substances found in papermaking waste pulp, along with sodium lignosulfonate, water glass, sodium humate, and either four or more such substances used in combination. 2. Based on their chemical composition, flocculants can be divided into inorganic salt flocculants, organic polymer flocculants, and microbial flocculants. There are few types of inorganic salt flocculants; they mainly include low-molecular-weight salts such as aluminum salts, iron salts, and hydrolyzed polymers, as well as inorganic polymers used as flocculants. Organic polymer flocculants mainly include synthetic organic polymer flocculants and naturally modified organic polymer flocculants. 3. Inorganic scale-inhibiting dispersants include sodium hexametaphosphate, etc ； Organic ones include polyacrylic acid tercopolymers, ATMP, DTPMP, HPPA, PBTCA, HEDP, EDPMPA, etc

The operating temperature during the sedimentation of black water is of utmost importance; generally, a temperature of around 40 degrees is ideal. Of course, it is also essential to use an appropriate amount of effective additives!

I know that polyacrylamide used in oil fields and water treatment is available for purchase, but there is a significant difference in quality and price.
