1. Operate strictly accordance with operation standards based on "natural gas purification equipment and operating specifications".

 2. As the purification effect can not reach the design targets the gas purification equipment using for a period of time to deprive of organic sulfur, inorganic sulfur, water, so the equipment needs regenerating treatment.  Because the device is not suitable for supplying natural gas when regeneration. Therefore, in order not to affect the continuous production, it would generally be ordered two boards (such as the A and B) or more. When it comes to alternately use, in particular, you should pay attention: If A need to regenerate, you should let the natural gas through B about 5 minutes stably before shut down the A.

 3. Ways of Waste gas treatment after regenerating: water-solution or combustion.  Ultimately targets: the sulfur in the waste gas is less than 0.5mg / m ³ or there is no smell (with wet palms on the exhaust sampling holes for 5 minutes), which mean that the regeneration is completed.
