NIR TECHNOLOGY USED FOR OPTIMIZED COST EFFECTIVE REFINERY PROCESS CONTROL

摘要

Commitment to continuous and strict quality control is inevitable to guarantee existence andrnsurviving in today's complex geo-political and highly competitive economic environment.rnEffective process control is essential to proceed refinery processes at maximum efficiency,rnmaximum accuracy and at minimum cost. It is undisputable that incorporation of on-linernprocess analyzers prevents financial losses, caused by unnecessary re-processing orrngiveaways. The question is not "IF" to use analyzers but "WHAT" type of analyzer keeps thernrefinery cost effective at top performance. ASTM based process analyzers to control thernquality are an option, but enormous investments are required in purchase and maintenance.rnAlternatively, a sophisticated solution of NIR technology is successfully applied in refineryrnprocess control and optimization. Fast on-line analyses, based on correlation of NIR spectrarnwith quantified multiple physical properties, guarantee compliance with the productrnspecifications. The uniqueness of this system is that optical fibers transmit NIR beams fromrnthe analyzer, in the "safe zone" control room, to and from measuring probes on processrnstreams up to a distance of 2 miles. Multiplexing instantaneously measures different processrnstreams. Incorporated validation software ongoing verifies, validates and adjusts NIRrnanalytical results according to laboratory analyses, which guarantee continuous reliability ofrnanalytical data.
