  • Publication number: 20250135488
    Abstract: Apparatuses, systems, and methods for dispensing a liquid are described. Apparatuses and systems can dispense a liquid in a dispense operation at a dispense rate from a start point on a substrate surface to a terminate point on the substrate surface. A measurement device can detect geometric parameters of a shape formed by the dispensed liquid on the substrate surface. Control circuitry can control at least one of an approach speed at which the dispenser approaches the start point prior to the dispense operation and an exiting speed at which the dispenser moves away from the terminate point subsequent to the dispense operation based on the detected geometric parameters of the shape. Algorithms can operate on remote or local software and control systems, or as part of an edge computing system or Internet of Things (IoT) system.

  • Publication number: 20240218273
    Abstract: Certain zinc-based scavengers can scavenge sulfur compounds from fluids containing one or more hydrocarbons, water and the sulfur compound, but may leave deposits of insoluble zinc sulfide (ZnS) which can be problematic. When the zinc-based scavengers are used together with at least one zinc sulfide deposition preventer, deposition of zinc sulfide can be reduced or eliminated. The sulfur compound may be hydrogen sulfide (H2S). Suitable zinc-based sulfur compound scavengers include, but are not necessarily limited to, a zinc carboxylate, a tetramine zinc carbonate, zinc carbonate, zinc ammonium carbonate, zinc chelates, and/or zinc lignosulfonate. Suitable zinc sulfide deposition preventers include, but are not necessarily limited to, sodium salts of a phosphorous-based polymer, polymeric ammonium salts, acrylic sulfonate non-ionic terpolymers, and/or modified acrylic acid polymers.
