Vent-gas monitoring and regulatory compliance system for natural gas production equipment

A data logging system for vent-gas monitoring equipment, comprising:

• a) a plurality of data collection sensors positioned throughout a vent-gas monitoring system, the sensors configured to measure:
• compressor packing vent flow rates;
• compressor packing vent pressures;
• engine crankcase vent parameters;
• methane concentration levels;
• andoperational parameters;
• b) a data processing unit configured to:
• receive sensor data at per-second intervals;
• calculate greenhouse gas emissions metrics from the sensor data;
• and
• process operational parameters and emissions data;
• c) a data storage system configured to:
• record operational parameters and emissions data at per-second intervals;
• generate daily exportable data files containing the logged data;
• and
• format the data files for regulatory compliance reporting.

A regulatory compliance monitoring system for natural gas equipment, comprising:

• a) a vent-gas monitoring system configured to measure:
• fugitive gas flow rates from multiple emission sources;
• methane concentrations from compressor packings and engine crankcases;
• b) a programmable logic controller (PLC) configured to:

• calculate methane emissions based on measured flow rates and concentrations;
• calculate greenhouse gas emissions metrics;
• c) a regulatory compliance module configured to:
• monitor methane emissions in accordance with regulatory thresholds for NSPS OOOO b/c emission limits;
• calculate methane emissions reduction based on captured fugitive gases;
• track emissions data for Waste Emissions Charge (WEC) calculations;
• and
• generate compliance reports for environmental regulations including NSPS OOOO b/c and MERP requirements;
• d) a data logging system configured to generate exportable compliance documentation.
