MOLECULAR SIEVES BATTERY

The Cold air from the cascade cooler & chilling tank is partly free from moisture, Oil & Oil Vapors. The separation of moisture is carried out in different stages so that the air entering in the molecular sieve battery has minimum moisture level & better adsorption of CO² can take place. The Molecular Sieve Battery thus completely removes the moisture & CO² from the air passing through it. If the battery does not function efficiently the moisture & CO² will enter into Air Separation Column and Moisture will become Ice & CO² will become Dry Ice form which will choke the Expansion Valves, heat exchanger tubes and other equipment's resulting in the stoppage of the Plant.

Liquid Oxygen Pump

It is a single acting, Single Cylinder, Horizontal Type, Non Lubricated, Reciprocating Pump, Pumps liquid Oxygen & gasifies in heat exchangers for final filling as gas in cylinders at a pressure of 150 kg/cm2 g.

Liquid Oxygen Pump when is Started, the liquid oxygen from the main condenser enters the outer jacket of the pump. Some of this liquid evaporates due to heat produced in pumping and the vapour is passed to the upper column as gas. The major part of liquid oxygen is taken into the pump cylinder and then compressed out by the piston Forward stroke. This high pressure liquid oxygen passes through two non-return valves into the heat exchangers, Gasified and filled in to cylinders through Filling Manifolds.

Liquid Nitrogen Pump

It is a single acting, Single Cylinder, Horizontal Type, Non Lubricated, Reciprocating Pump, Pumps liquid Nitrogen & gasifies in heat exchangers for final filling as gas in cylinders at a pressure of 150 kg/cm2 g.

Liquid Nitrogen Pump when is Started, the liquid Nitrogen from the condenser bottom cone enters the outer jacket of the pump. Some of this liquid evaporates due to heat produced in pumping and the vapour is passed to the upper column as gas. The major part of liquid Nitrogen is taken into the pump cylinder and then compressed out by the piston Forward stroke. This high pressure liquid Nitrogen passes through two non-return valves into the heat exchangers, Gasified and filled in to cylinders through Filling Manifolds.

Air Separation Column (Cold Box)

Air separation column (cold box) consists of outer steel casing, Main heat exchangers, Bottom column, Top column, Condensor, Sub-coolers, Liquid nitrogen Tank. Expansion Valves, Drain & Analysis Valves, Niddle Valves Insulation material, Digital electronic temperature indicator & scanner, PT 100 sensors, Differential Pressure level Indicator.

The expanded air leaving from the Expansion Engine & Air Expansion valve enters Air Separation Unit. The rich liquid containing Oxygen & Nitrogen is collected in Lower column having more than 40% O². The rich liquid from the lower column is taken to the upper column through RL Expansion Valve. The Poor Liquid (PL) collected on the bottom cone of Condensor is taken to upper column through PL Expansion Valves in this process pressure is dropped 4.5 kg/Cm² to 0.5kg/Cm² g in upper column . The Nitrogen being more volatile come out and oxygen getting condensed and collected in condenser from where it is pumped by LO²/LIN Pump in to cylinders.
