DEVICE AND METHOD FOR MEASURING SOLUBILITY OF ELEMENTAL SULPHUR IN SULPHUR-CONTAINING GAS

摘要

Disclosed are a device and method for measuring the solubility of elemental sulphur in a sulphur-containing gas. The device comprises a displacement pump (1), a first sampler (6), a high-temperature box (18), a back pressure pump (21), a control valve (20), an adsorption tank (23), a low-temperature box (48), a flow meter and a collection tank (35), wherein an outlet of the displacement pump (1) is in communication with an inlet of the first sampler (6); an outlet of the first sampler (6) is in communication with a first inlet of the control valve (20); a second inlet of the control valve (20) is in communication with an outlet of the back pressure pump (21); an outlet of the control valve (20) is in communication with a first opening of the adsorption tank (23); a second opening of the adsorption tank (23) is in communication with the flow meter; a third opening of the adsorption tank (23) is in communication with the collection tank (35); the first sampler (6) is located in the high-temperature box (18); the adsorption tank (23) is located in the low-temperature box (48); a valve (7) is arranged between the outlet of the first sampler (6) and the first inlet of the control valve (20); a valve (32) is arranged between the third opening of the adsorption tank (23) and the collection tank (35); and the collection tank (35) is suited for being heated.
