| 20130035534 | METHOD AND AN APPARATUS FOR NGL/GPL RECOVERY FROM A HYDROCARBON GAS, IN PARTICULAR FROM NATURAL GAS - A method for separating methane from at least one hydrocarbon with two or more carbon atoms in a substantially gaseous fluid, containing more than 3 ppm of water, in particular a natural gas coming from a natural gas field or from a natural gas pipeline, or a refinery gas or another gas available at an extraction pressure set between 15 and 300 bar, and an apparatus. The method provides prearranging an expansion device having at least one first expansion equipment, selected from the group comprised of: a radial expansion device and a static expansion device, in which a first expansion takes place with a cooling effect down to a temperature that is higher than the solid formation temperature that may be formed starting from water and/or hydrocarbons present in said gas, and further having at least one second expansion equipment which is arranged downstream of the first expansion equipment. | 02-07-2013 |

| 20100228070 | Method for Achieving High Purity Separation and Refinement of Controlling Morphology and Particle Size of 2,6-Dimethylnaphthalene Dicarboxylic Crystals - The present invention relates to a method for achieving high purity separation and refinement by controlling morphology and particle size of 2,6-dimethylnaphthalene. And more particularly, the present invention relates to a method for obtaining high purity 2,6-dimethylnaphthalene crystals, in which crystallization is carried out with a solvent that enables the crystals to form a square-platy shape. During the process, crystallization variables such as, stirring speed, cooling speed, solvent and composition ratio, are adjusted to control morphology and particle size of 2,6-dimethylnaphthalene and to remove aggregation, thereby obtaining 2,6-dimethylnaphthalene crystals of high purity. | 09-09-2010 |
