Floating type device for producing methanol from natural gas and storing and offloading methanol

Abstract

The invention relates to the technical field of oil and gas deep processing, and discloses a floating type device for producing methanol from natural gas and storing and offloading the methanol. The device can be applied to rivers, lakes and seas. The device comprises a ship type floating body, a start-up boiler device and methanol producing process devices. The start-up boiler device and the methanol producing process devices are arranged on a deck of the ship type floating body. The methanol producing process devices sequentially comprise a natural gas purification device, a natural gas conversion device, a methanol synthesis device and a methanol rectification device from upstream to downstream. The front end of the natural gas purification device is connected with a natural gas pipeline, an outlet of the start-up boiler device is connected with the natural gas conversion device, a seawater desalination device is arranged in the ship type floating body, an outlet of the seawater desalination device is connected with a desalted water device, and an outlet of the desalted water device is connected with the natural gas conversion device; a methanol intermediate product cabin and amethanol product cabin are further arranged in the ship type floating body, the output end of the methanol synthesis device is connected with the methanol intermediate product cabin, the methanol rectification device is connected between the methanol intermediate product cabin and the methanol product cabin. According to the device, the adopted natural gas is clean energy, dust emission is avoided, and the environment is protected.

Description

technical field [0001] The patent of the invention relates to the technical field of deep processing of oil and gas, and can be applied to floating natural gas methanol production and methanol storage and unloading devices in rivers, lakes and seas. Background technique [0002] Methanol is an important energy and chemical raw material, and is widely used in chemical production. The natural gas methanol production process is a mature and industrialized production process. Compared with the coal methanol process, the natural gas methanol process has less pollution and lower energy consumption. Low advantages, especially with the rapid development of the natural gas industry, using natural gas as raw material to produce methanol products has always been a preferred methanol production process, which is very competitive in the market. [0003] The world's demand for methanol is increasing year by year. From 2010 to 2015, under the influence of the rapid development of China's c...
