Abstract:
A method for making proppant particles is provided. The method can include providing a slurry of ceramic raw material, the slurry containing a reactant including a polycarboxylic acid, and flowing the slurry through a nozzle in a gas while vibrating the slurry to form droplets. The method can also include receiving the droplets in a vessel containing a liquid having an upper surface in direct contact with the gas, the liquid containing a coagulation agent. The method can further include reacting the reactant with the coagulation agent to cause coagulation of the reactant in the droplets. The droplets can then be transferred from the liquid and dried to form green pellets. The method can include sintering the green pellets in a selected temperature range to form the proppant particles. In one or more exemplary embodiments, the reactant can be or include a PMA:PAA copolymer.

Claim (Index 14):
The method of  claim 13 , wherein the coagulation agent is calcium chloride.
