RECTIFICATION COLUMN FOR SEPARATION OF STEAM-GAS MIXTURE OF WATER VAPOUR, AMMONIA AND HYDROGEN SULPHIDE Russian patent published in 2020 - IPC B01D3/16 C01C1/00 

FIELD: treatment of water, industrial and household waste water.

SUBSTANCE: invention relates to devices for separation of sulphurous-ammonium waste water treatment products and can be used in chemical industry. Rectification column includes housing with branch pipes for supply and removal of vapour and gas and liquid phases, circulating cooled irrigation systems, contact devices, distributors of bottom and top circulating irrigation and blind collector plate equipped with gas duct. Attachment contact devices are located in its lower and upper parts, the dish-shaped contact device is located in its middle part. Blind collector plate equipped with a gas duct separates the upper packing device from the dish-shaped contact device.

EFFECT: technical result consists in improvement of efficiency of separation of steam-gas mixture of water vapour, ammonia and hydrogen sulphide, optimization of vapour-liquid load, elimination of phenomena of spray mud and fluid failure, as well as in ensuring required degree of purity of separation of steam-gas mixture of water vapour, ammonia and hydrogen sulphide.
