The Golmud refinery attaches importance to clean development and economic development. The plant listed dry gas and liquefied gas desulfurization equipment as key environmental protection projects during the “11th Five-Year Plan†period. The project successfully produced qualified liquefied gas and dry gas on December 22, 2007. In the past, due to the high sulphur content of dry gas, there was a serious equipment corrosion problem when using it as a fuel. In view of this situation, the plant has accelerated the implementation of dry gas, liquefied gas desulfurization, acid water stripping and sulfur recovery projects and construction steps. After the production, the sulfur content in the dry gas is reduced from 5000 ppm to less than 20 ppm. The whole plant heating furnace and boiler are all converted to dry gas, which reduces the consumption of natural gas.
The 100,000-ton methanol plant desorption gas recovery and utilization device is also a key point in the construction of energy-saving and emission-reduction projects of this plant. Since it was fully put into use in December 2007, it has received good results and can save nearly 400 standard cubic meters of fuel and gas per hour. At the same time, the exhaust emissions from the methanol plant are greatly reduced.
The two environmental protection devices have significant effect on energy conservation and emission reduction
On January 22, the dry gas and liquefied gas desulfurization equipment of the Golmud refinery of the Qinghai Oilfield and the desorption and recovery device of the desorption gas of the 100,000 tons methanol plant operated for more than one month, maintaining a high-quality, high-efficiency level, and achieved good results. Economic and social benefits.
