  • Patent number: 7054822
    Abstract: A network advisory system that provides advisory information to a field service provider and/or a management system is disclosed. The network advisory system receives collected data from one or more destination facilities and analyzes the information to generate advisory information. If the advisory information is deemed time-critical, the information is automatically transmitted to a management system to alert the system that a time-critical situation is resident at a destination facility. The management system may determine one or more appropriate field service providers to address the time-critical situation. If the advisory information is not deemed time-critical, the information may be stored by the network advisory system until access by a requesting entity—either a management system or a field service provider.

  • Patent number: 7053037
    Abstract: A pseudo-stable phase-splitting solvent composition that forms a single liquid phase when subjected to mild agitation and retains that single phase while the composition is applied to a surface, but which forms two or more laminar liquid phases promptly after being applied. A concentrated solvent film forms on the surface, under a film containing the other phase. The solvent preferably is denser than water, and the composition preferably is diluted with water. This enables the solvent to attack the surface at near full strength, and provides a water seal over the solvent film. The solvent composition can be used full strength or in diluted form for cleaning, reducing the microbial population of, or degreasing a variety of surfaces, and for stripping a variety of difficult-to-remove coatings from surfaces.

  • Patent number: 7018967
    Abstract: Enhanced cleaning can be obtained by applying primarily to a stained region of a washable soft substrate a prespotting composition that contains at least one molybdate and which can generate singlet oxygen in situ in the presence of a peroxide, optionally applying to the substrate a prespotting composition that contains at least one peroxide, and rinsing, laundering or otherwise cleaning the substrate, using a peroxygen-containing built detergent to clean the substrate if a prespotting composition containing peroxide has not been applied to the substrate. Preferred embodiments of the method can provide stain removal comparable to that obtained using chlorine bleach but with better color safety.

  • Patent number: 7008913
    Abstract: Disclosed is a process for the treatment of a plant gaseous stream containing odor compounds including hydrogen sulfide, an alkyl mercaptan or an alkyl thiol and mixtures thereof by contacting the plant stream with an oxidizing agent that reduces the odor but forms elemental sulfur. The elemental sulfur, and other inorganic, scales that form, or deposit, can be suppressed or removed using a specific aromatic substituted nonionic surfactant material. The use of such a process produces a significant improvement in odor quality while maintaining a clean process facility and low operating pressure drop.

  • Publication number: 20060042665
    Abstract: A method of cleaning equipment such as heat exchangers, evaporators, tanks and other industrial equipment using clean-in-place procedures and a pre-treatment solution prior to the conventional CIP cleaning process. The pre-treatment step improves the degree of softening of the soil, and thus facilitates its removal. The pre-treatment solution can be a strong acidic solution, a strong alkaline solution, or comprise a penetrant. A preferred strong acidic solution is an acid peroxide solution. In some embodiments, the pre-treatment may include no strong alkali or acid ingredient; rather, the penetrant provides acceptable levels of pre-treatment.
