Figure 1. Schematic presentation of the laboratory installation for hydrogen sulfide sequestration from a gaseous mixture: 1-membrane contactor; 2-composite hollow fiber membranes; 3-pump for metal ions acidic solutions; 4 and 5-gas-liquid separator; 6- homogenization The reactor is a prefabricated structure, has the form of a cylindrical pipe with flanges. The
tubular part consists of outer and inner cylinders (the main chamber of the reactor) made of heat-
resistant glass. The cylinders are arranged coaxially.
The outer glass cylinder has a length of 300 mm and a wall thickness of 3 mm, closed from
the sides with metal flanges. The diameter of the working area is 70 mm. On the walls
The outer cylinder has two holes for supplying power to the inner electrode. In the center of
the flange there is a hole with a diameter of 14 mm through which the tubes pass to the inner
cylinder. Tubes are intended for supply and removal of gases and formed products. Parallel to the
main gas flow, there is a nitrogen gas flow entering the space between the cylinders. The function
of gaseous nitrogen supplied to the cavity between the cylinders is to protect against fire in case of
leakage of the main chamber of the reactor, and is also a dielectric. The gas pressure is kept within
1.3-1.4 atmospheres, which increases the breakdown voltage behind the main chamber of the
reactor (Paschen's law).
The inner cylinder with a diameter of 42 mm has a length of 270 mm and is closed from the
ends with round plugs made of organic glass. A central electrode made of a metal rod is attached to
the plugs and metal tubes are connected. The volume of the inner cylinder is isolated from the outer
space.
The overall height of the reactor assembly is 335 mm. The volume of the working zone of
the reactor is 350 cm

The central electrode consists of a metal rod. On this rod are mounted round metal plates,
pointed along the perimeter. Number of plates varies between 10-20 pieces. At both ends of the rod,
clamps are installed, which are a round flat washer. In the washer, located on the side of the gas
inlet, holes are made that serve to swirl the incoming flow.
Large-scale turbulence is given to the main gas to be cleaned, supplied to the central
electrode, to optimize the destruction processes. After Process decomposition gas with decay
products goes to the sulfur trap. The pressure difference at the inlet and outlet of the main chamber
of the reactor is measured using a differential pressure gauge.
