Seeking help with coal-to-natural gas
Thread Content
First, I would like to ask a simple question from all the friends here: In coal-to-natural gas projects, the gasification unit uses dry coal as feedstock. So what are the purposes of the high-pressure nitrogen and low-pressure nitrogen produced by the air separation unit? The feasibility study states that high-pressure nitrogen is supplied to the gasification unit, while low-pressure nitrogen is provided to the users throughout the plant. But what exactly are the devices referred to as \"users throughout the plant\"? The amount of nitrogen separated by the separable device is quite large; can it be used throughout the entire plant to meet its needs, or what should be done with it?
All plant users refer to various production units, such as gasification, shift cooling, purification, methane synthesis, and thermal power plants. Nitrogen can be used for purging and displacing equipment pipelines, and liquid nitrogen products are also available
Low-pressure nitrogen has many uses, such as purging and displacing in various devices, as well as raising the temperature of nitrogen in heat exchange cooling systems.
It should be a Luchi furnace; the operating pressure is 2–10 Mpa. When feeding coal, it’s necessary to use a rammer inside the coal lock, I guess
