Description
Método para o transporte de gás natural composto por cápsulas pneumáticas e referida cápsula pneumática Campo da invenção A presente invenção refere-se a um método de transporte de gás natural e respectiva cápsula, cujo método é baseado na utilização de múltiplas cápsulas pneumáticas, formando barcaças movimentadas sobre o mar por rebocadores.Field of the Invention The present invention relates to a method of conveying natural gas and its capsule, the method of which is based on the use of multiple pneumatic capsules, forming moving barges. over the sea by tugboats.
Estado da técnica Atualmente a indústria de gás e petróleo utiliza métodos compostos normalmente por navios que transportam o gás natural pressurizado ou em seu estado líquido. Esse método atual é representado pelas patentes US 6339996, US 3566824, US 5803005 e US 5839383.State of the art The oil and gas industry currently uses methods typically composed of ships carrying pressurized or liquid natural gas. This current method is represented by US 6339996, US 3566824, US 5803005 and US 5839383.
Esse modelo tradicional de transporte normalmente compreende um navio composto por tanques de alta pressão que são os responsáveis por estocar o gás em questão. O processo para comprimir ou liquifazer esse gás no caso de trechos curtos (100km a 300 km) é extremamente ineficiente energeticamente sendo responsável pelo alto custo atualmente relacionado com transporte de gás natural. O método de compressão assim como o de liquefação são instalados em plataformas marítimas ou perto das unidades produtoras, isso muitas vezes torna a implementação desses métodos inviável economicamente. O método prosposto é composto por um conjunto de múltiplas cápsulas pneumáticas flexíveis (Exemplo: 40 unidades) formando um bloco flutuante para ser rebocado e levar o conteúdo para descarga em local apropriado, transportando o gás natural sem resfriamento ou compressão, apenas ventilado com pressão ínfima para dentro das cápsulas.This traditional transport model typically comprises a ship made up of high pressure tanks that are responsible for storing the gas in question. The process of compressing or liquefying this gas in the case of short stretches (100km to 300km) is extremely energy efficient and is responsible for the high cost currently associated with natural gas transportation. The compression method as well as the liquefaction method are installed on offshore platforms or near the production units, this often makes the implementation of these methods economically unfeasible. The proposed method consists of a set of multiple flexible pneumatic capsules (Example: 40 units) forming a floating block to be towed and to bring the contents to discharge in an appropriate location, transporting natural gas without cooling or compression, only ventilated with minimal pressure. into the capsules.
Objetivo da Invenção A presente invenção tem como objetivo diminuir custo logístico da cadeia do gás natural dos poços offshore, oferencendo um método, bem como uma cápsula paneumática para transportar gás em estado natural (CNTP - condições normais de tempreratura e pressão), possibilitando a retirada de gás em áreas distantes (sem gasoduto) inviáveis para o processo de GNL ou de GNC.OBJECTIVE OF THE INVENTION The present invention aims to decrease the logistic cost of the offshore wells natural gas chain by providing a method as well as a panatic layer for transporting natural gas (CNTP - normal temperature and pressure conditions), allowing the removal gas in distant areas (without pipeline) not feasible for the LNG or CNG process.

A camisa ou membrana (4) flexível é fixada na parte média (meio) da cápsula com dimensão aproximada de metade da cápsula pneumática (1). Por ser flexível, a membrana (4) se deforma de acordo com os volumes de gás natural e ar.The capsules (1) have control that regulates the gas levels of the same and ballast (13), acting as a self compensator for buoyancy variations and internal compensations for possible leakage. This control has an integrated circuit that operates automatically by activating the valves (7, 8 and 9) capable of exchanging gases between the capsules, pumping natural gas into and out of the capsules (1). docking the pneumatic capsule assembly (1) at a production unit, refueling station or a production lung that supplies these capsules with natural gas. The control manages the distribution of natural gas to the capsules (1) by inflating the natural gas compartments (6) using valves (7, 8 and 9) and pumps. At the same time the automatic control releases the air outlet from the air compartment (5) compensating the lift gain by pumping water to the ballast (13). Shortage occurs by docking the pneumatic capsule assembly (1) in a receiving unit, receiving station or a receiving lung that receives natural gas from the capsule assembly. The automatic control manages the emptying of natural gas (6) from the capsules (1) by inflating the air compartments (5) using the valves (8) and pump. At the same time automatic control releases the natural gas outlet from the housing (6) compensating for the loss of lift by pumping water out of the ballast (13). The invention further comprises said pneumatic capsule (1) which is constructed of flexible material, which may be plastic and / or woven, or any other resistant material that supports pressure, containment and transport, with thickness varying according to the material employed. large in size, divided into compartments by jacket or flexible membrane (4) to separate air (5) and natural gas (6). The flexible jacket or membrane (4) is made of flexible material and may be plastic and / or woven, or any other resistant material that supports pressure and containment. It is disposed internally in the pneumatic capsule (1), being responsible for separating the natural gas (6) and air (5) compartments. The flexible jacket or membrane (4) is fixed to the middle (middle) of the capsule approximately half of the pneumatic capsule (1). Being flexible, the membrane (4) deforms according to the volumes of natural gas and air.
Os compartimentos possuem válvulas (7 e 8) para abastecimento de gás natural (6) e ou de ar (5).The compartments have valves (7 and 8) for supplying natural gas (6) and or air (5).
Na parte inferior da cápsula pneumática (1) é disposta uma válvula de controle (9) para o lastro (13) que é o elemento fundamental para equilíbrio do conjunto.In the lower part of the pneumatic capsule (1) a control valve (9) is arranged for the ballast (13) which is the fundamental element for balancing the assembly.
