Benefits of technology

The invention is a new process for making syngas from natural gas. It involves using a solid material that has been oxidized to react with the natural gas and produce a reduced solid material. This reduced solid material is then regenerated by oxidizing it under reaction conditions to produce the oxidized solid material again. The process can also include adding steam to increase the hydrogen content of the syngas. The reaction conditions are very hot and the pressure is very high. The technical effect of this invention is a more efficient and effective way to make syngas from natural gas.

Problems solved by technology

However, there is much natural gas that is located in remote locations, and needs to be transported without the ability to feed the natural gas into a pipeline.

Embodiment Construction

[0010]Natural gas is traditionally collected and transported to plants for processing. The primary use of natural gas is for heating, and is processed by removing water, inert gases, and natural gas liquids, or higher molecular weight hydrocarbons found in natural gas. The natural gas is then compressed, or liquefied for transport. However, one new technology is to convert natural gas to methanol for transport as a liquid. This saves on compression costs, and / or liquefaction costs, and provides for a safer material to transport.

[0011]Another process for changing the traditional compression and liquefaction of natural gas, is to convert the natural gas to syngas, or synthesis gas. The first steps will be to remove inert components in the natural gas, such as nitrogen, argon, and carbon dioxide. Natural gas liquids will also be recovered and directed to other processing or transport. The treated natural gas will comprise primarily methane and some ethane with small amounts of higher a...

Abstract

A process for the conversion of natural gas to syngas. The process uses a solid oxidizing agent in place of an oxidizing gas for the partial oxidation of the natural gas.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a process for converting natural gas into other commercial products. Specifically, the invention relates to the production of syngas from natural gas using a solid oxidizing agent.[0002]Natural gas generally refers to light gaseous hydrocarbons, and especially comprising methane. Natural gas also contains hydrocarbons such as ethane, propane, butanes, and the like. Natural gas is recovered from underground reservoirs, and is commonly used as an energy source for heating and power generation. Typically, natural gas is recovered at high pressure, processed and fed into a gas pipeline under pressure. Natural gas can comprise undesirable components, such as carbon dioxide, nitrogen and water, which can be removed with technology commonly available. One example is the use of adsorbents for removing non-hydrocarbon components of the natural gas, and or sulfur compounds.[0003]Natural gas is usually processed to recover heavi...
