New product

ASME PTC 40-2017 Flue Gas Desulfurization Units

standard by ASME International, 03/23/2018

Full Description

This Code provides procedures for the conduct and reporting of performance tests of flue gas desulfurization systems (FGDS). The application of this Code is limited to the process and equipment employed to remove sulfur dioxides from flue gas or other sulfur-dioxide-laden gas streams. The methodology described may be adapted for assessment of removal of other emissions if agreed to by the parties to the test. This Code does not apply to removal of sulfur oxides from gases during the combustion process.

Types of systems covered:
(a) Dry FGD System. An FGD system process in which a flue gas containing sulfur oxides passes through an alkaline material but is not saturated with moisture; the gas leaves the reactor at a temperature above the adiabatic saturation, thus producing a dry by-product or dry waste product.
(b) Wet FGD System. An FGD system process in which a flue gas containing sulfur oxides passes through an alkaline material and is saturated with moisture, thus producing a wet by-product or wet waste product.
(c) Regenerable FGD System. An FGD system process that regenerates and recycles the sorption medium.

      NOTICE


      All Performance Test Codes must adhere to the requirements of ASME PTC 1, General Instructions. The following information is based on that document and is included here for emphasis and for the convenience of the user of the Code. It is expected that the Code user is fully cognizant of Sections 1 and 3 of ASME PTC 1 and has read them prior to applying this Code.

      ASME Performance Test Codes provide test procedures that yield results of the highest level of accuracy consistent with the best engineering knowledge and practice currently available. They were developed by balanced committees repre- senting all concerned interests and specify procedures, instrumentation, equipment-operating requirements, calculation methods, and uncertainty analysis.

      When tests are run in accordance with a Code, the test results themselves, without adjustment for uncertainty, yield the best available indication of the actual performance of the tested equipment. ASME Performance Test Codes do not specify means to compare those results to contractual guarantees. Therefore, it is recommended that the parties to a commercial test agree before starting the test and preferably before signing the contract on the method to be used for comparing the test results to the contractual guarantees. It is beyond the scope of any Code to determine or interpret how such compar- isons shall be made.


      FOREWORD


      When the twin issues of environmental protection and the need to assure a reliable supply of energy became important public concerns in the 1970s, The American Society of Mechanical Engineers (ASME) Board on Performance Test Codes began to explore the possibility of addressing these concerns within the test code framework. As a result of these discussions, the PTC 40 Committee on Flue Gas Desulfurization (FGD) units was organized in 1978; it held its first meeting in April 1979. The PTC 40 Code draft was approved by the Board on Performance Test Codes on May 11, 1990. The Code was adopted by the American National Standards Institute as an American National Standard on March 19, 1991.

      In 2006, the ASME Performance Test Code Standards Committee restarted the PTC 40 Committee. This edition of ASME PTC 40 addresses advances in new technology. Specifically, this edition applies to different types of FGD systems: wet FGD, dry FGD, and regenerable FGD. It applies the various U.S. Environmental Protection Agency (EPA) methods that exist today.

      This Code was approved by the PTC Standards Committee on March 13, 2017, and approved and adopted as an American National Standard on May 23, 2017.
