Embodiment 1: absorption-desorb linkage test
With different sour gas, for example, one or more in the sour gas such as sulfur dioxide, carbon dioxide, hydrogen sulfide, nitrogen oxide mix in blender 1 with nitrogen, oxygen etc.Mixed sour gas is through heater 2.3 bottom enters absorption tower 3 from the absorption tower by the sour gas of the mixing after heater 2 heating, absorption liquid in the lean solution storage tank 7 is squeezed into the top on absorption tower 3 with pump, in absorption tower 3 with reverse contact of sour gas of flowing from bottom to top, thereby the acidic components in the mist are hunted down and are trapped in the lean solution.
The Purge gas that has removed acidic components flows to cat head, carries out the condensation dehydration through gas-liquid separator 4.Be discharged in the atmosphere after the detection of gas after the condensation dehydration through sulfur dioxide speed changer 5.Liquid after the condensation dehydration returns the top on absorption tower 3, continues to use as lean solution.
The rich solution that has absorbed acidic components converges the back and flows into rich solution storage tank 6 at the bottom of tower.After this, the rich solution in the rich solution storage tank 6 enters heat exchanger 10, carries out heat exchange in heat exchanger 10 Yu from the lean solution of desorber 11, thereby makes rich solution be heated.Then, the rich solution after being heated enters straight tube heater 9 and is heated once more.
Entered desorber 11 by the rich solution after straight tube heater 9 heating from the top of desorber 11.In desorber 11 inside, the rich solution that flows downward contacts with the mist of steam is reverse with the high temperature desorption gas that upwards flows.Acidic components in the rich solution are partly desorbed along with steam flows to cat head together.After cat head is through 12 condensations of straight tube condenser, enter gas-liquid separator 13.The gas of being separated by gas-liquid separator 13 leaves desorber 11 and enters sulfur dioxide speed changer 14, and the liquid that is separated returns the top of desorber 11 and proceeds desorb.Separate the lean solution that sucks and enter heat exchanger 10 and carry out heat exchange with rich solution in the tower still of desorber 11 bottoms, enter straight tube condenser 8 then and further cool off, cooled lean solution enters lean solution storage tank 7.
Embodiment 2: absorption test
Do not carry out in the process of desorption experiment only carrying out absorption test, with different sour gas, for example, one or more in the sour gas such as sulfur dioxide, carbon dioxide, hydrogen sulfide, nitrogen oxide mix in blender 1 with nitrogen, oxygen etc.Mixed sour gas is through heater 2.3 bottom enters absorption tower 3 from the absorption tower by the sour gas of the mixing after heater 2 heating, absorption liquid in the lean solution storage tank 7 is squeezed into the top of absorption tower (3) with pump, in absorption tower (3), contact, thereby the acidic components in the mist are hunted down and are trapped in the lean solution with sour gas from bottom to top is reverse.
The Purge gas that has removed acidic components flows to cat head, carries out the condensation dehydration through gas-liquid separator 4.Be discharged in the atmosphere after the detection of gas after the condensation dehydration through sulfur dioxide speed changer 5.Liquid after the condensation dehydration returns the top on absorption tower 3, continues to use as lean solution.And the rich solution that has absorbed acidic components converges back inflow rich solution storage tank 6 at the bottom of tower.
With absorb-the desorb linkage test is different, when only carrying out absorption test, by the valve (not shown) of control rich solution storage tank 6, rich solution in the rich solution storage tank 6 no longer enters straight tube heater 10, that is, no longer enter desorber 11, but adopt lean solution storage tank 6 to carry out absorption test.
