A Dickson-type reactor is an experimental arrangement that can be used to simulate various processes occurring in hydrothermal systems under laboratory conditions.
Dickson-Type Reactor
The method
This fle?xi?ble re?ac?tion cell set?up was in?iti?al?ly de?scri?bed by Dick?son et al. (1963) and la?ter si?gni?fi?cant?ly mo?di?fied by Sey?fried et al. (1979, 1987). It can be uti?li?zed to in?ves?ti?ga?te equi?li?bri?um pro?ces?ses that oc?cur wi?t?hin hydro?ther?mal sys?tems. Flu?id and so?lid re?ac?tants re?si?de wi?t?hin a cor?ro?si?on re?sis?tant fle?xi?ble re?ac?tion cell made of gold or ti?ta?ni?um (Wu et al. 2016). Pres?su?re and tem?pe?ra?tu?re can be ad?jus?ted in?de?pen?dent?ly up to a le?vel of 50 MPa and 400 °C. The set?up al?lows for con?co?mitant flu?id sam?pling and so?lid re?ac?tants can be re?co?ve?r?ed upon ter?mi?na?ti?on of an ex?pe?ri?ment. Four cust?o?mi?zed au?to?cla?ve sys?tems are avail?able in the Hydro?ther?mal Lab (Hy?Lab) of the Pe?tro?lo?gy of the Oce?an Crust re?se?arch group.
