Multi Column Distillation Plant

Listing ID #4713613

The WFI Still work on the distillation principle.

The first column is heated by the external Plant steam. The generated vapor by the feed water rises up the column where it is subjected to the entrainment separation system.

Multidirectional baffles deliver the first punch. The steam generated from the first column is made to pass a torturous path through multidirectional baffles. Here the pyrogen particles and droplets separate and are guided to the end of the column.

A centrifugal type cyclone separator high up in the column delivers the second punch. Here the vapor is guided through a narrow circular channel where it begins to rotate.

The vapor flow subjects the pyrogenic impurities and droplets to a high centrifugal force thereby dislodging them from the vapor steam. The distillation units are connected in series into a multiple effect system and external energy is required only at the first column. The steam generated in each column is supplied to the subsequent column.

The generated steam vapor of the last column and the almost condensed steam distillate (2nd column onward) is led to the over head cooling heat exchanger, where it is cooled by the cooling water & incoming feed water to generate WFI.

Features

• Komal’s Multi-Column Distillation Plants (MCDP) are designed to produce pyrogen/endotoxin free water conforming to IP/BP/EP/USP standard.
• These individual columns are designed , constructed and tested per the American Society of Mechanical Engineers (ASME, Section VIII, Division 1- Unfired Pressure Vessels) since they operate at pressures as high as 6 to 10 bar
• All Evaporator (columns) sheets and tubes as well as all surfaces in contact with Pure Steam or distillate are constructed of 316L stainless steel with inside electropolish and Teflon gaskets.
• All tubes joints are Orbital welded and qualified with videoscopy.
• Full-Automatic PLC based Control Panel System with auto sanitization and printing facility.
• First column equipped with Double tube sheet as a provision to avoid boiler steam mixing with Purified water.
• Komals WFI-Combo design optimizes the Control Panel by combining the panel for WFI Generation and Distribution system
• Plants are available from 50 Liters/hour to 10000 Liters/hour.
• Complete documentation to meet and exceed international audit requirements.
