Gas compression is the process of reducing the volume of a gas by applying pressure. This is commonly achieved using devices called compressors, which can be found in various applications, such as in refrigeration systems and natural gas pipelines. By compressing gas, its density increases, allowing for more efficient storage and transportation. In industrial settings, gas compression plays a crucial role in processes like petroleum refining and chemical manufacturing. It helps in moving gases through pipelines and in the production of energy. Understanding gas compression is essential for optimizing performance and ensuring safety in these operations.
