Offshore oil production units produce off-gases and other hydrocarbons which need to be flared or piped to on-shore units for processing. Often, the location of the well and the amount of these gases produced may not make it economical to lay pipelines for processing. The instant disclosure describes a barge mounted gasification system that will allow for off-gas liquefaction and enhanced oil recovery.
A floating production, storage and offloading (FPSO) unit is a floating vessel used by the offshore oil and gas industry for the processing of hydrocarbons and for storage of oil. An FPSO vessel is designed to receive hydrocarbons produced from nearby platforms or subsea template, process them, and store oil until it can be offloaded onto a tanker or, less frequently, transported through a pipeline. FPSOs are preferred in frontier offshore regions as they are easy to install, and do not require a local pipeline infrastructure to export oil. FPSOs can be a conversion of an oil tanker or can be a vessel built specially for the application. A vessel used only to store oil (without processing it) is referred to as a floating storage and offloading vessel (FSO). Also under construction are floating liquefied natural gas (FLNG) vessels, which will extract and liquefy natural gas on board.
The instant barge mounted gasification unit has many features: It will accept off-gases and flare gases, or any other hydrocarbons, from a FPSO or other deep see oil and gas platform. It will gasify, or partially oxidize these gases and convert them to a liquid, such as methanol, for easy storage and transportation. It will provide CO2 produced in the process back to the platform for enhanced oil recovery. It will also provide other utilities, such as power, steam, nitrogen or desalinated wate...
