Background
The liquid ammonia refining device is used for purifying crude liquid ammonia, after light and heavy components of the crude liquid ammonia are separated in the refining tower, H2S is removed from top gas ammonia through the zinc oxide adsorption tank, and the desulfurized gas ammonia is cooled to obtain a liquid ammonia product with high quality. The filling material in the zinc oxide adsorption tank is a desulfurizer, the running time of the desulfurizer is changed once for 4000 hours in half a year, and the total sulfur content to be removed in half a year is as follows: 1.89X 4000X 50X 10-6=0.378 ton, calculated according to the desulfurizer penetration sulfur capacity of 10%, 3.78 tons of desulfurizer needs to be filled in half a year, and the stacking density of 1.0kg/l needs 3.8m of desulfurizer for carrying out high speed planting. Under the actual operation condition, liquid ammonia refining is discontinuously operated, and the zinc oxide desulfurizer is replaced once a year. The specification of the zinc oxide adsorption tank is phi 1200 multiplied by 5000. A zinc oxide desulfurizer replacement step: 1. the zinc oxide adsorption tank is decompressed, isolated and replaced; 2. opening a manhole at the upper part of the adsorption tank; 3. taking out the grating plate, the steel wire mesh and the alumina porcelain balls; 4. opening a manhole at the lower part, and discharging the spent desulfurizer; 5. charging a new desulfurizer; 6. and (4) repacking the steel wire mesh, the alumina porcelain balls, the grating plate and the manhole. And (3) replacing, namely when the alumina porcelain is taken out in the step 3, a person is required to enter the zinc oxide adsorption tank to collect scattered porcelain balls by using a container and then convey the porcelain balls out of the storage tank. When the ceramic ball is reloaded, people are required to enter the tank to backfill the ceramic ball.
