Nitrogen generators for petroleum and chemical industry coverage

Nitrogen generator for the oil and gas industry with 99.9% purity， 6 KG/CM2 working pressure and 70 NM3/HR power.

Nitrogen is a gas found in large quantities in the air. It has many applications such as food processing， heat treatment， metal cutting， glass manufacturing， chemical industry and many other processes that rely on nitrogen in some form or capacity.

Nitrogen is commonly used in the oil and gas industry for applications including well stimulation， injection and pressure testing. Nitrogen can also be used to flood marginal fields in some EOR (enhanced oil recovery) projects， more commonly using water flooding or chemical/surfactant flooding. In addition， nitrogen can be used to help prevent flammable gas flaring and to protect tubing from downhole corrosion.

Nitrogen Sequestration

Nitrogen filling， also known as tank filling and tank lining， is a process in which nitrogen is applied to storage vessels consisting of chemicals and hydrocarbons that are volatile and react with oxygen. When a tank is purged with nitrogen， the materials inside the tank are not in contact with oxygen. Purging gives the product a longer life and reduces the potential explosion hazard.

Nitrogen purging

To replace any undesirable or hazardous atmosphere with an inert， dry atmosphere， nitrogen purging is used， i.e.， to limit the oxygen content so that it does not react with other explosive mixtures and hydrocarbons. Displacement and dilution are the two most common purging methods. Which method is suitable for which system depends on its geometry. The displacement method is more effective for simple systems and the dilution method is used for complex systems.

Cooling the refinery catalyst

When a refinery is to be shut down， it is advisable to minimize the temperature of the catalyst associated with the process as early as possible. To do this， pumping equipment can be used to deliver large amounts of nitrogen to the catalyst to cool it quickly and save downtime.
