Abstract: The invention relates to a process for the removal of SO2, HCN and H2S and optionally one or more compounds from the group of COS, CS2 and NH3 from a first gas stream, which process comprises the steps of: (a) removing SO2 from the first gas stream by contacting the first gas stream in a hydrogenation zone with a hydrogenation catalyst in the presence of hydrogen to obtain a second gas stream; (b) removing HCN and optionally COS and/or CS2 from the second gas stream obtained in step (a) by contacting the second gas stream in a hydrolysis zone with a hydrolysis catalyst in the presence of water to obtain a third gas stream; (c) removing NH3 from the third gas stream by contacting the third gas stream in a NH3-removal zone with an aqueous acidic washing liquid to obtain an ammonium-comprising aqueous stream and a fourth gas stream; (d) removing H2S from the fourth gas stream by contacting the fourth gas stream in a H2S-removal zone with an aqueous alkaline washing liquid to obtain a H2S-depleted gas stream and

Abstract: A device for administering a liquid in a number of doses, such as insulin to a patient, comprising a piston (3) in a pump chamber (4), a cannula (5) being connectable to the pump chamber, a piston rod (14) connected to the piston and having an operating button (25), a valve (1) and a reservoir (2), wherein by retracting the piston (3), at the same time the reservoir is connected to the pump chamber (4) through the valve in order to fill the pump chamber and the valve is moved into the position for closing the connecting element (6) between the pump chamber and the cannula (5) and wherein, by moving the piston forward, at the same time the connecting element between the pump chamber and the cannula is connected through the valve to the pump chamber and the valve is moved into the position for closing the passage (7) between the reservoir and the pump chamber.
