Abstract:

By analyzing 8 key flare emission vents in a typical ethylene plant, this paper proposes an optimized plan for the design of two ethylene plants sharing interconnected pipelines to reduce energy consumption and environmental pollution. The scheme for reducing emissions under various operating conditions by use of a crossed pipeline is put forward, and the material recovery and emission reduction schemes under abnormal conditions such as startup, shutdown and accident fluctuation are proposed.

Key words: two ethylene plants, interconnected pipeline, startup and shutdown, emission reduction
