Abstract
Enhanced macromixing, mesomixing, and micromixing of multiple discrete reactant streams, particularly for precipitation reactions of low density pumpable fluids, are obtained by controlled continuous high pressure multiple reactant streams flowing into a chemical mixer/reactor. Individual reactant streams are pressurized to about 8,000 to 50,000 psi and achieve velocities up to about 250 meters/second in the final stage of the chemical mixer/reactor. Reactant flows are controlled by a combination of a fixed restriction and a variable driving pump.
Claims16
A method of preparing a reaction product of a first liquid and a second liquid comprising the steps of:
- (a) pressurizing the first liquid to a pressure of at least 8,000 psi;
- (b) pressurizing the second liquid to a pressure of at least 8,000 psi;
- (c) controllably delivering the pressurized first liquid and the pressurized second liquid in stoichiometric amounts to a reaction chamber at a pressure of at least 8,000 psi and at a velocity of about 1.5 to 20 meters per second when the liquids combine to cause reaction between the first liquid and the second liquid to form the reaction product.
A method of preparing a reaction product of a first liquid and a second liquid comprising the steps of:
- (a) pressurizing the first liquid to a pressure of at least 8,000 psi;
- (b) pressurizing the second liquid to a pressure of at least 8,000 psi;
- (c) controllably delivering the pressurized first liquid and the pressurized second liquid in stoichiometric amounts to a reaction chamber at a pressure of at least 8,000 psi to cause reaction between the first liquid and the second liquid to form the reaction product, wherein after the pressurized first and second liquids meet to form a combined stream, the velocity of the combined stream increases.
