METHOD AND COMPOSITION FOR PULSE DOSE CLEANING OF PROCESS STREAMS
Pulse dosing is used to administer a cleaning formulation into a fluid process stream flowing through structural components of a processing facility. The fluid process stream may contain corn, corn-derived products, or a combination thereof, or the fluid process stream may contain a process condensate, a rinse fluid, a cleaning fluid or any combination thereof. The processing facility may be an ethanol processing plant, a protein processing plant, a corn oil processing plant, an ethanol and corn oil processing plant, an ethanol and protein processing plant, or an ethanol, corn oil and protein processing plant. Pulse dosing may include administering the cleaning formulation into the fluid process stream for a period of x seconds every y minutes, with no administration of the cleaning formulation between the periods of x seconds.

Cleaning agent and preparation method and use thereof
Provided are a cleaning agent and a preparation method and the use thereof. The cleaning agent is prepared from the following raw materials comprising the following mass fraction of components: 0.5%-20% of an oxidant containing iodine, 0.5%-20% of an etchant containing boron, 1%-50% of a pyrrolidinone solvent, 1%-20% of a corrosion inhibitor, 0.01%-5% of a metal ion-free surfactant, and water, with the sum of the mass fraction of each component being 100%, the pH of the cleaning agent is 7.5-13.5, and the corrosion inhibitor is one or more of a benzotriazole corrosion inhibitor, a hydrazone corrosion inhibitor, a carbazone corrosion inhibitor and a thiocarbohydrazone corrosion inhibitor. The cleaning agent can efficiently remove nitrides from hard mask residues with little effects on metals and low-κ dielectric materials, and has a good selectivity.
