LABORATORY UNIT FOR GAS ABSORPTIONGENERALAbsorption is the intake of gases in awashing liquid by physical solving orreversible chemical reaction. Depen-ding on whether the gas by physical sol-ving or by chemical binding is bound itis a physical or a chemical absorption.When a mixture CO2/air gets in touchwith water, the CO2 gas is absorbed inthe water but the air is not solved. Theabsorption capacity of the water for car-bon dioxide depends on the influencetime, the pressure and the temperature.This unit provides the facility the carbondioxide to wash out of the carbon dioxi-de/air mixture. Due to the ratio of theboth components determining the sepa-rating effect, the solvent flow and the gasflow are aimed varied.

Construction of the Laboratory unit for gas absorptionThe core of the unit is the absorption column consisting of theabsorption tube (K), a gas inlet (G) and a siphon part (S). Thementioned parts are connected with conical ground joints NS 45/40 and fitted with a silver coated high vacuum jacket.The absorption column has an inner diameter DN 50 and alength of approx. 1400 mm. The inlet component (E) seats onthe upper end of the column and at the lower end seats thesiphon part with the drain valve.The both gases air and CO2 are introduced via the connec-tions 1 and 2, adjusted with the valves (V2) and (V3) andmixed together in the mixer (M) then fed over the heatexchanger into the absorption column which is filled withRaschig rings 4/4 mm. The absorption liquid water is directedfrom the top towards the gas in counter flow from vessel (B1)with the pump (P) and over a flow meter (Q1) and the heatexchanger (W1).The both heat exchanger (W1) and (W2) are connected witha thermostat (TS). Through this is reached that absorption gas

and absorption liquid are fed with the same temperature intothe absorption column. The issued gas is directed for analy-sis into a gas analyser (GA). The inlet gas can be also analy-sed by switching of the three way stopcock (VD). Followingdata can be captured via a data logger in the unit:

- Temperature at the water inlet (T1)- Temperature at the gas inlet (T2)- Temperature in the siphon (T3)- Electric conductivity at the water inlet (L1)- Electric conductivity in the siphon (L2)- Differential pressure above the column (DD)- Gas concentration (GA)

The measuring can be analysed at the PC with a suitable soft-ware.

LABORATORY UNIT

GENERALThis NORMAG unit for absorption ofreaction gas distinguished by its com-pact construction which meets the highrequirements for such units. The onlyused materials are Borosilicate glass 3.3and PTFE. Additional safety give powdercoated glass parts if required. Only oneflange connection will contact theabsorption liquid, the other connectionsare located in the gas part. The flangeconnections and all other spherical gro-und joints are polished and allow a longdwell time of the unit. Due to this fact,high concentrated bases as absorptionliquids can be used. The connectionsare sealed with PTFE seals. High vacu-um spindle valves made of Borosilicateglass 3.3 and PTFE serve for the lockingof the gases and the absorption liquid.The unit is suitable for use under vacu-um and available in different types. Thesizes 6 litres and 10 litres are designedfor laboratory purposes. For this unit weoffer a mobile frame, made of stainlesssteel tube, with safety bath.

Construction of the absorption unitThe core of this NORMAG unit for absorption of reaction gasis the absorption column which is sealed on the receiver forthe absorption liquid. The absorption liquid is cooled by adouble coil, made of Borosilicate glass 3.3, inside the absorp-tion receiver. Connections for the cooling are flanges Pl 15providing the facility to connect a thermostat hose. Two glassadapter for coupling flange Pl 15 and olive D11 are part of thedelivery. The NORMAG glass pump for forced liquid circulati-on of the absorption liquid with magnet drive is located belowthe receiver, guaranteeing a quick exchange. Normally, thepump volume is 120 litres/h by 1500 revs/min, but the pumpvolume can be changed with the control device. Due to safetyreasons, the suction and pressure tubes are inside theabsorption column. To increase the reaction surface, Raschigrings as packing are used. The gas to be purified is introdu-ced via the HV spindle valve 3 into the unit and rises in theabsorption column. The pumped up absorption liquid runsover the Raschig rings towards the gas and the mass transfercan start. The drain off of the purified gas is effected by theconnected manifold with spindle valves. The flange andthread connections at the receiver serve for the refilling of theabsorption liquid and for taking a thermometer or pH-sensor.A connection, which serves for cleaning the unit is sealed onthe head of the absorption column. The used absorption liquidcan be drained off by opening the spindle valve at the pump,then the unit can be cleaned and after closing the valve a newabsorption liquid can be introduced. For automatic use, anaddition funnel is tightly connected with the receiver, so thatthe absorption liquid can be refilled automatically.

Construction of the high vacuum pump standThe pump stand consists of two easy to dismantle single ele-ments, connected with high vacuum flanges in different sizes.Between the flanges are centring rings with Viton sealing,giving a safe seal and centring of the flanges.The connections for taking vacuum and inert gas are robusthigh vacuum double spindle valves. The stems of these val-ves can be made as NS-cone, glass thread or olives, just forcustomer's requirements. Two safety/overpressure valvesguarantee that the unit will not be injured, caused by failure inoperating.Due to the pre-fitting of several cold traps it is possible to con-dense gaseous parts in the suction line. A connection with ahigh vacuum flange DN 16 provides the facility to connect avacuum meter with capacitive sensor. The locking of the unit versus the vacuum pump is effectedwith a great high vacuum spindle valve DN 15. A chemvac combined pump stand serves as vacuum pump.This guarantees the reaching of a sufficient vacuum, and thechemical resistant design ensures a wide range of applicati-ons.

The vacuum pump stand is integrated in a mobile frame ofstainless steel tubes, tube diameter 26.9 mm. Rollers give the possibility to move the stand within the labo-ratory.

Construction of the short path evaporator unit DSV 80This short path evaporator with roll wiper cage is used fordistillation of temperature sensitive products in vacuum ran-ges from 1-10-3 mbar. The dwell time in the heating zone isonly a few seconds. The composition of the condenser in thecentre of the evaporator, direct in face to the heating surface,enables the running of short path distillations.

The short path evaporator type DSV 80 is made of Borosilica-te glass 3.3 and is suitable for short path distillations in labo-ratories. The evaporator has an inner diameter of 75 mm anda heating surface of 0.058 m². The heating is effected with aliquid medium.

A rotating roll wiper cage produces a liquid film on the eva-porator surface. The armature is powered from outside via alaboratory agitator and vacuum magnet stirrer seal. Thevapours condense at the condenser in the centre of the eva-porator. The distillate runs down over the condenser into thedistilling receiver. The not distilled sump product is sampledin a ring line below the heating zone and lateral led into thesump receiver. The evaporator can be used for liquid sub-stances with an higher viscosity too.

Operation pressure: 760 mbar to 10-3 mbarMedium heatingtemperature: max. 250 °CDistillation volume: 0.3 to 1 kg/hDimensions of the frame: L x H x D 1500 x 2000 x 600 mm
