Abstract
Способ извлечения более тяжелых компонентов, например, NGL из потоков жидкости, таких, как поток (потоки) богатого LNG (RLNG) с высокой экономией. Способ включает стадию, на которой поток RLNG нагревают в теплообменнике (теплообменниках) (LNGX) посредством парового потока верхнего погона колонны, не требуя разделения потоков исходного материала на сырье и флегму путем разделения до LNGX или после него. Исходный жидкий богатый RLNG перерабатывают, получая жидкий NGL и одновременно возвращая очищенный продукт бедного LNG (LLNG) в его жидком виде. Способ осуществляют практически без необходимости в оборудовании для компримирования. Кроме того, способ без компрессоров обеспечивает испаренный природный газ под давлением для транспортировки трубопроводами и отвечающий техническим условиям на транспортировку трубопроводами. Это система, которая может гибко изменять составы и технические характеристики продуктовых NGL/бедного LNG/трубопроводного газа и работать в режимах извлечения NGL с глубоким 99% извлечением этана (С2) и задерживанием этана (С2) в соответствии с техническими условиями на транспортировку трубопроводами с экономией оборудования и потребности в энергии.A method for extracting heavier components, such as NGL, from fluid streams, such as rich LNG (RLNG) flux (s) with high savings. The method includes a stage in which the RLNG stream is heated in a heat exchanger (heat exchangers) (LNGX) by means of a column overhead vapor stream without requiring separation of the feedstock feedstock into raw materials and reflux by separation before or after LNGX. The original liquid rich RLNG is processed to obtain liquid NGL and at the same time return the purified product of poor LNG (LLNG) in its liquid form. The method is carried out almost without the need for equipment for compression. In addition, the method without compressors provides evaporated natural gas under pressure for transportation by pipelines and meets the technical requirements for pipeline transportation. It is a system that can flexibly change the composition and technical characteristics of NGL / lean LNG / pipeline gas products and operate in NGL extraction modes with a deep 99% ethane extraction (C2) and ethane retention (C2) in accordance with the specifications for pipeline transportation with savings equipment and energy needs.
