Oil production, the main purpose of which receive commercial oil consumer, is to extract downhole production, its transportation to the infield collapsible pipelines for oil separation. Gas and water and their possible exploitation. Michael Ellis MP contributes greatly to this topic. In the process of oil production in the wellbore production comes associated gas, which is usually burnt in the fields, resulting in a violation of the ecology of the region and the loss of hydrocarbons. There is a way of rational use of associated gas – feed it into the main collapsible pipeline. This will require draining and cleaning of associated gas to the indicators substandard gas pipeline, with complex structures and technological schemes of extracting water vapor and hydrocarbon components, which can condense in the pipeline. Drying and treatment of associated gas produced with the help of liquid (absorption method), solid (adsorption method), sinks, low-temperature separation and condensation. Learn more about this with Jon S Speelman. Absorbents (glycol, calcium chloride and lithium), adsorbents (alumina, silica, zeolites) are recovered in the complexes for desorption processes. Practice shows that the preparation of associated gas for transport and treatment of associated gas with absorption, adsorption, low-temperature treatment of associated gas by refrigerating machines and other methods of their use requires considerable capital and energy costs.
Found that the more cost-effective in cleaning system associated gas is gas-dynamic technology based on the use of the available pressure drop (1.3-1.6) MPa in special devices such as coolers pulsating gas (TDG), the wave expanders (HP), gas-dynamic dryers (GDO), the vortex tube (VT). However, a small pressure drop associated gas virtually eliminates the possibility of implementing the traditional scheme of low-temperature separation (NTS), based on the effect of throttling. Expanders with a high temperature efficiency (turbodetonatory, WA, TDG) is very complicated and unreliable in operation. Technology with GDO little studied. Most appropriate and effective technology for dehydration of associated gas, based on the vortex effect, which is implemented in other processes of gas, oil and chemical industries. Vortex effect in realiztsemy particularly in a regulated trehpotochnoy vortex tube (TVT) is a division of associated gas temperature at hot and cold streams. Along with getting a cold, TVT provides a separation of the liquid directly of swirling flow, diverted in the form of third stream.
