| Abstract: | Process design and equipment selection of a 5 kt/a liquid sulphur dioxide plant are described,which uses sodium citrate process with reasonable process parameters and equipment and materials.The plant has operated for more than one year and every operation index reached or was superior to design value.Actual operation showed that the consumption of sulphur was 0.45 t/t,power 110 kWh/t,citric acid 10 kg/t,soda ash 18 kg/t and 0.3-0.4 MPa steam 0.4 t/t.Several issues that need attention in design and production are discussed,such as selection of pipeline material,control of inlet gas temperature of SO,absorption tower and sodium citrate concentration, and tail gas treatment. |
