摘要:
A process for extracting a target gas component from a gas mixture in an apparatus having a pair of capture and release sections is provided. The pair of capture and release sections includes a sorbent capture section and a sorbent release section, each of the sorbent capture section and sorbent release section having a high surface area medium and a sorbent contained therein. A gas mixture is directed through a flow path, the flow path directing the gas mixture through the sorbent release section followed by the sorbent capture section, wherein the sorbent within the pair of capture and release sections extracts the target gas component and reduces the target gas component in the gas mixture. The sorbent is directed through a recirculation path, the recirculation path directing sorbent from said collection tank of the sorbent capture section to the entry point of the sorbent release section and directing sorbent from the collection tank of the sorbent release section to the entry point of the sorbent capture section, thereby recycling the sorbent.
摘要:
The invention concerns a capture tank for capturing a captive target compound from a gaseous and/or vaporous mixture comprising at least the captive target compound and one other material, or for capturing, concentrating or crystallising a target compound from a liquid mixture or solution comprising the target compound and at least one other material, the capture tank comprising an enclosure having a top region, a bottom region and at least one side defining the enclosure, the enclosure being at least partly open in its top region in order to communicate in use of the capture tank with the gaseous and/or vaporous mixture and for permitting ingress of a gaseous and/or vaporous mixture into the enclosure; the enclosure communicating in its bottom region with a reservoir for receiving the captured captive target compound; having means associated with its at least one side and/or its bottom region for permitting egress from the enclosure of the gaseous and/or vaporous mixture in at least partially captive target compound-depleted form; and having means for sparging at least partially through the enclosure from top to bottom a liquid mixture or solution for entraining the gaseous and/or vaporous mixture in the enclosure and carrying the entrained gaseous and/or vaporous mixture towards the bottom region of the enclosure, and a process for its operation.
摘要:
A series of devices, methods and compounds for dosing corrosion inhibitors and cleaners to closed loop systems, boilers, towel rails, heat exchangers and heat stores. The devices and materials can be designed to allow corrosion inhibitors and cleaners to be built into boilers, radiators, heat stores, and any other similar devices. The chemicals are either bound into a gel or dissolved within the crystal lattice of a phase change compound. It is possible to design materials that will rapidly release the chemicals at elevated temperatures. These materials allow cold water flushing of systems without releasing the chemicals. The devices can also be modified to incorporated softening resin to remove the hardness from the system water and thereby prevent scaling.

Water can be separated from solutes in aqueous solutions by a process of forming water clathrates of gases under high pressure and low temperature conditions. The present invention outlines a series of processes where a low pressure stream of clathrate forming gas is entrained in a low pressure stream of water and carried to a region of high pressure where clathrates are formed. The clathrate crystals are then collected and separated from the solutes. The clathrate crystals are then taken to conditions that allow the clathrate to decompose to water and gas. The gas is maintained at elevated pressure and recycled to be used again as a feedstock in the process of the present invention.
摘要:
A process for chemical cleaning and corrosion inhibition of pipework, typically in closed loop systems, that avoids or significantly minimises the requirement for wastewater discharge where the system is first acidified using a mixture of cleaning agents capable of dissolving metal oxides. The method then precipitates any dissolved contaminants and separates the precipitate from the carrying fluid. Further elements of a combined corrosion inhibitor package are then added to any cleaning agent ions that remain in solution to develop a fully functional corrosion inhibition package to protect the metals of the system.
