Patent number: 9051816Abstract: A pressurized alkali dispersion supply system for use in permeabilizing a coal seam, and in particular for connecting together open zones in a coal seam using a (almost horizontal) linkage channel comprising a multitude of fine cracks. The system includes a source of alkali/alkali solution, a source of pressurized air, a supply pipe and a fogger for forming an alkali mist that is dispersed within the pressurized air. Cracks/fractures open up in the coal seam (ie. permeabilization) under the influence of the compressed air together with dissolution of humic acids by the alkali mist.Type: GrantFiled: February 8, 2012Date of Patent: June 9, 2015Assignee: Linc Energy LtdInventors: Victor Byzeev, Andrey Chernishov

Patent number: 8741181Abstract: This invention relates to a method and apparatus for treating a raw product stream (raw synthesis gas/raw syngas) generated by underground coal gasification (UCG). In one aspect, the invention concerns a method and apparatus for cooling and initial cleaning of raw syngas gas, so that the treated UCG product stream is suitable for downstream applications such as for energy or chemical production. In another aspect, the invention concerns a method and apparatus for isolating, treating and handling a raw UCG product stream that is generated either when igniting or decommissioning an underground coal gasifier and, due to its consistency, is generally unsuitable for energy or chemical production.Type: GrantFiled: December 23, 2011Date of Patent: June 3, 2014Assignee: Linc Energy LtdInventors: Grant Bollaert, Ernest Du Toit

Publication number: 20130312950Abstract: An ignition apparatus (150) configured to ignite an underground coal seam (151). The ignition apparatus (150) comprising an ignition system, a positioning system, a sensor (170) and a controller (165). The ignition system comprises ignition means and an ignition tool (155) for igniting the underground coal seam (151) from within the well channel (154) or well liner encasing the well channel (154). The positioning system comprises coiled tubing (156) connected to the ignition tool (155) and extendible through a well head (153) within the well channel (154) to position the ignition tool (155) at a desired location within the well channel (154). The positioning system further comprises a spool (157) for transporting and dispensing the coiled tubing (156).Type: ApplicationFiled: February 20, 2012Publication date: November 28, 2013Applicant: Linc Energy Ltd.Inventors: Fazal Uddin Shaikh, Casper Jan Hendrik Burger, Greg Martin Parry Perkins
