  • Patent number: 11492271
    Abstract: A system and method for removing ammonia from an ammonia-containing liquid is described. The system comprises a primary heat exchanger 12 for heating the ammonia-containing liquid to operational temperature, an ammonia stripper 14 for stripping ammonia from the ammonia-containing liquid from the primary heat exchanger and discharging it as ammonia-containing gas, and an acid scrubber 16 for reacting the ammonia in the ammonia-containing gas with acid to form an ammonium salt. The acid scrubber comprises a scrubbed air outlet 32 in fluid communication with a hot air inlet 20 of the ammonia stripper, such that scrubbed air which is discharged from the acid scrubber may be recycled for use in the ammonia stripper. Also described is a system and method for removing ammonia from an ammonia-containing liquid, wherein the system comprises a cold-water scrubber for removing ammonia from the ammonia-containing gas discharged from the ammonia stripper.

  • Publication number: 20180357327
    Abstract: The present invention provides a computer-implemented system and method for rapid capturing of the physical environment in a formal manner and connecting this formal representation to the data held in an organization's databases. The present invention includes a computer implemented system and method for accurate extraction of the “reality” into a formal model. In addition, the invention includes methods to divide the information by different aspects based on user defined and automatic tagging. The invention utilizes a modeling language to create a model, which includes a plurality of entities, to describe a physical environment and linking a plurality of external data associated with the physical environment with the plurality of entities.

  • Publication number: 20120125757
    Abstract: The present invention provides a pyrolysis system comprising an entrained flow pyrolyser having an opening through which biomass can be added. The pyrolyser also has an inlet for hot exhaust gas, an outlet for pyrolysed biomass and an outlet for syngas. The system has a burner for producing hot exhaust gas and a conduit between the burner and the hot exhaust gas inlet. A syngas extraction means for extracting syngas from the pyrolyser. The syngas extraction means extracts syngas from the pyrolyser at a rate such that the internal pressure within the pyrolyser never exceeds the pressure external to the pyrolyser.

  • Publication number: 20120097520
    Abstract: The invention provides a process and apparatus for the separation of a gaseous feed comprising a mixture of hydrocarbons and nitrogen gas, the process comprising the steps of: (i) cooling and at least partially condensing the gaseous feed; (ii) feeding the cooled and at least partially condensed feed from step (i) to a fractionation column comprising reboil to produce an overhead hydrocarbon vapour stream enriched in nitrogen and a condensed hydrocarbon product stream low in nitrogen, wherein prior to the fractionation, the feed stream is divided into at least two streams including: a) a first stream which is expanded and fed to the fractionation column; b) a second stream which is expanded, heated and fed to a lower stage of the fractionation column than the first stream, (iii) removing a hydrocarbon product stream low in nitrogen from the fractionation column; and (iv) removing a hydrocarbon vapour stream enriched in nitrogen from the fractionation column.

  • Publication number: 20120090355
    Abstract: The invention provides a process and apparatus for the separation of nitrogen from a gaseous feed comprising a mixture of hydrocarbons and nitrogen gas, the process comprising the steps of: (i) cooling and at least partially condensing the gaseous feed; (ii) feeding the cooled and at least partially condensed feed from step (i) to a first fractionation to produce an overhead vapour stream having an enriched nitrogen content and a condensed product having a reduced nitrogen content which is subjected to a second fractionation, which comprises reboil, at a lower pressure than the first fractionation; (iii) partially condensing the overhead vapour stream, and separating to provide a liquid stream, which is used to provide reflux to the first fractionation, and a separated vapour stream, which is condensed to provide reflux to the second fractionation; and (iv) sub-cooling the condensed product of the first fractionation and dividing the resulting sub-cooled product into at least two streams: a first stream being

  • Publication number: 20100003381
    Abstract: A mobile concentration system (MCS) for milk comprising: a vehicle having a holding tank for receiving and holding milk; and a concentration system mounted to the vehicle and coupled in fluid communication with the holding tank. The concentration system adapted to remove milk from the holding tank and process the milk while the vehicle is stationary and/or uploading or unloading of milk, or underway. The concentration system including a reverse osmosis filtration system adapted receive the milk from the holding tank and process the milk to generate a stream of substantially water and a product stream of concentrated milk. A feed section comprises product/water/CIP (clean in place) valving systems, high pressure pumping equipment operating to receive and pressurize the milk through-out the system. A concentration level control system includes a control valve regulating the concentrate flow to achieve a fixed system operating pressure to control the system.

  • Publication number: 20030230195
    Abstract: A process and equipment for extracting and disposing of sour reservoir components initially contained in natural hydrocarbons. The stream of natural hydrocarbons extracted from a reservoir is initially subjected to an optional gas/liquid separation. The gaseous hydrocarbons are then scrubbed with a liquid absorbent to dissolve sour reservoir components such as hydrogen sulphide and carbon dioxide and thereby form a solution. The liquid absorbent may be water that is preferably sufficiently free of oxygen and solids to be of a quality suitable for re-injection. The solution is pumped back into a well. The well may be the reservoir that produced the hydrocarbons, or adjacent geological formations, with the re-injected sour water being employed for production stimulation. Alternatively, the well may be a depleted reservoir. The scrubber may be a multiple-stage packed column or tray column that preferably allows for condensate skimming.
