Methods of making cross-linked pelletized chemicals

A method for producing cross-linked chemical treatment agent particles, comprising:

• introducing a core pellet to a fluidizer including one or more atomizing nozzles;
• mixing a chemical treatment agent with a cross-linker to provide a mixture;
• heating the mixture to a first temperature between about 150° C. to 250° C.;
• and
• applying the heated mixture to the core pellet in the fluidizer at a second temperature between about 120° C. to about 130° C. to provide a cross-linked chemical treatment agent particle, wherein applying the mixture to the core pellet in the fluidizer includes spraying the mixture through the one or more atomizing nozzles of the fluidizer, wherein:
• the cross-linked chemical treatment agent particle comprises a cross-linked chemical treatment agent layer surrounding the core pellet,
• the core pellet comprises kaolin, bauxite, or a combination thereof,
• the cross-linked chemical treatment agent layer comprises the chemical treatment agent cross-linked with the cross-linker by bonds selected from the group consisting of ester bonds, amide bonds, imide bonds, phosphoester bonds, and combinations thereof,
• the cross-linker is selected from the group consisting of a polyol, a polyamine, an amino alcohol, and combinations thereof,
• the chemical treatment agent comprises a scale inhibitor,
• the cross-linked chemical treatment agent layer comprises about 65 wt % to about 95 wt % of the cross-linked chemical treatment agent particle,
• the cross-linked chemical treatment agent particle has a size of about 4 mesh to about 120 mesh, and
• the cross-linked chemical treatment agent particle comprises a compressibility of about 10% to about 90% at pressures of up to about 1000 MPa.
