摘要:
A method for purifying dry cleaning solvents containing laundry soils. The method employs membrane filtration to enhance the separation of the contaminants from the dry cleaning solvent.
摘要:
A fabric article treating system, and more particularly to a fabric article treating system comprising at least a fabric article active delivery stage and a fabric article transporter capable of passing a fabric article in need of treatment through the fabric article active delivery stage such that a fabric article active is delivered to the fabric article is provided. Methods of treating fabric articles, especially with the fabric article treating system is also provided.
摘要:
The present invention relates to a system for processing a lipophilic fluid, more particularly to a system for processing a lipophilic fluid utilized in a fabric treating process, even more particularly to a system for processing a lipophilic fluid such that contaminants such as water, surfactants, water, body/food oils, fatty acids, and dyes can be removed from the lipophilic fluid. In other words, the present invention relates to the "cleaning up" of or purification of a lipophilic fluid such that it can be re-used in a lipophilic fluid system.
摘要:
A cleaning system comprising a reservoir of cleaning solvent, a fabric article treating vessel and a filtration device for removing contaminants from the cleaning solvent. The filtration device comprises at least an adsorbent material having an Adsorbent Capacity of at least about 200 mg contaminants per gram of adsorbent. A method for using the same is also disclosed.
摘要:
The present invention relates to processes for removing contaminants from lipophilic fluids, adsorbent materials employed in such processes, and lipophilic fluids produced by such processes.
摘要:
A process for purifying dry cleaning solvents from a mixture containing used dry cleaning solvents and contaminants, such as laundry soils, fabric treating agents, the process comprising the steps of: (a) obtaining a mixture comprising a lipophilic fluid and one or more contaminants; (b) chemically modifying the contaminant, (c) contacting the mixture with a purification agent, thereby changing the solubility of the contaminant in the mixture; and (d) separating the contaminant from the lipophilic fluid.
摘要:
The present invention relates to processes for removing water and/or surfactants from lipophilic fluids, absorbent materials employed in such processes, and lipophilic fluids produced by such processes.
