Pipeline-Gas Demonstration Plant. Phase I: Demonstration Plant Engineering and Design. Volume 19: Plant Section 3000 - Flare.

摘要

Contract No. EF-77-C-01-2542 between Conoco Inc. and the US Department of Energy provides for the design, construction, and operation of a demonstration plant capable of processing bituminous caking coals into clean pipeline quality gas. The project is currently in the design phase (Phase I). This phase is scheduled to be completed in June 1981. One of the major efforts of Phase I is the process and project engineering design of the Demonstration Plant. The design has been completed and is being reported in 24 volumes. This is Volume 19 which reports the design of Plant Section 3000 - Flare. The purpose of the flare is to burn combustible streams that are vented from equipment during emergency, start-up, or other abnormal situations. The Demonstration Plant is equipped with one flare. There are two flare header systems in the plant; the high pressure header and the low pressure header. Each header is continually purged with nitrogen to prevent the accumulation of combustible mixtures. Relief valve discharges flow through the header to a knockout drum where entrained liquids are separated and recovered. Vapors flow up the flare stack and are combusted at the flare tip. Fuel gas is continually sent to the flare tip to maintain a pilot light. Steam and air injected into the tip provide smokeless operation. (ERA citation 06:029879)
