Flare network monitorng system and method

摘要

A flare monitoring system that receives real-time data associated with the release of a processing facility's combustible fluids to a flare stack and analyzes the data in conjunction with parameters of the processing facility's flare-through elements such as manual valves, control valves, restriction orifices, flow meters, and the like. The results of the analysis are provided to operators in the form of reports that indicate: whether flaring events are of a routine or non-routine nature; the flared volume; the contribution of the flare-through elements to the flared volume; and so forth. The results can aid operators in reducing combustible fluid losses due to flaring and in mitigating emissions of sulfur, nitrogen and carbon dioxide.

主权项

1. A flare monitoring system to ascertain quantitative data concerning flare events within a commercial or industrial processing facility, the flare monitoring system comprising:
a network of flare-through elements in controlled or passive fluid communication with one or more upstream fluid sources and each generating a data signal; a processor coupled to a memory; the fluid sources being flare fluid contributors for which the quantity of flare fluid at each source is estimated by a plurality of processing modules associated with the processor and the memory including:
a data historian module operable to:
store into memory parameters of the flare-through elements concerning the relationship between generated data signals and quantitative fluid flow values;store into memory data concerning the fluid sources upstream of the flare-through elements;receive (and store) real-time data signals generated by the plurality of flare-through elements; and a computation module that computes estimated flare fluid contributor quantities from each flare-through element associated with a fluid source as a function of received data signals associated with each flare-through element, parameters of the flare-through element and information concerning the fluid source.
