The plant's synthesis gas plant is a supporting device for butanol, its heavy oil gasification uses heavy oil pressure gasification, each set of oil injection capacity is designed according to 4 tons/hour, after technical transformation, the design capacity is increased to each gasification Furnace oil 6.15 tons / hour. Three zinc oxide desulfurization tanks are used in the synthesis gas plant. The design requirements for each zinc oxide desulfurization tank are changed every two years. No. 1 zinc oxide desulfurization tank was put into use in May 2007, and the service life has been extended for one year.
The plant organized technical personnel to tackle the problem, take measures to strengthen the ADA desulfurization, reduce the ADA desulfurization output below 2 mg/m3, adjust the temperature of the zinc oxide desulfurizer catalyst layer, and other measures to increase the control temperature from the original 180 °C to the present About 210°C, the capacity of sulfur was increased, and the stable operation of the desulfurization system was strengthened to avoid the contamination of the desulfurizer caused by the liquid. These measures have greatly improved the service life of zinc oxide desulfurization tanks.
The chemical plant of Jilin Petrochemical Company recently organized technical personnel to strengthen the ADA (azoformamide) desulfurization effect and adjust the temperature of the catalytic layer of the zinc oxide desulfurizer to further extend the service life of the zinc oxide desulfurization tank No. 1 in the syngas installation. Savings of 560,000 yuan.
