CI/CHLOR PAMPHLET 5 PDF

This pamphlet is intended to assist in the design, construction, location, installation and inspection of liquid chlorine storage systems. The recommendations are based on storage in horizontal, cylindrical tanks. This pamphlet does not apply to in-process pressure equipment (e.g. heat exchangers, vaporizers). Some recommendations in this pamphlet may apply to small process tanks, both horizontal and vertical. The recommendations may have to be modified to meet local requirements. More basic information on safe handling of chlorine may be found in CI Pamphlet 1 (11.1). Prospective designers and operators of such facilities must be familiar with such information and are referred to the chlorine supplier and material referenced.

It is recognized that storage facilities built prior to the publication of this edition of this pamphlet may be operating successfully without adhering to all recommendations contained herein. Operators of such facilities should evaluate discrepancies and validate that they do not pose disproportionate risks to safe operation or the environment. Continued operation without adhering to all aspects of this pamphlet is generally acceptable provided that:

• Previous successful long-term operations, coupled with periodic hazard evaluations, show that risks to safe operations and the environment are acceptable based on analysis of historical performance and process hazard assessment.

• The system does not violate applicable codes or regulations.

• Consideration is given to modifying the system to meet recommendations contained in this edition of the pamphlet when redesign or replacement projects are planned.
