Flow Generation & Combustion

Portable Flow and Combustion Equipment

Pipeline maintenance, commissioning, pigging and integrity work can require gas to be moved through, transferred from or removed from a pipeline segment under conditions the permanent system was not designed to provide. MRR develops temporary flow-management strategies around the operating objective of the project. Depending on the application, that can include portable flow generation, temporary compression, gas transfer or recovery, line evacuation and controlled combustion when recovery is not practical. The objective is to manage the gas deliberately while minimizing unnecessary product loss, emissions and operational disruption.

Flow on Demand, Less to Vent

Generate the Required Flow

Temporary equipment can establish or supplement the pressure and flow required for commissioning, pigging, ILI and other pipeline operations.

Recover Gas Where Practical

Where system configuration permits, gas can be transferred or recompressed rather than immediately released from the isolated segment.

Manage Residual Gas

When recovery is not practical, enclosed combustion can provide another engineered method of managing residual natural gas.

Engineer the Flow Plan

Temporary gas movement is a hydraulic problem before it is an equipment problem. MRR begins by understanding what the operation actually requires: pipeline volume and geometry, initial and final pressures, required flow or velocity, available receiving system, allowable backpressure, gas composition, schedule, site constraints and the objective of the work. Priorities differ by application - gas velocity and flow stability matter most for pigging or inline-inspection support, while gas recovery, final pipeline pressure and inventory management matter most for depressurization work - and MRR develops the temporary equipment arrangement and operating sequence around those conditions rather than simply mobilizing a compressor or combustion unit.

Portable Flow Generation & Gas Recovery

Temporary compression can establish flow where the permanent system cannot provide the required conditions, and depending on pipeline configuration, the same approach can transfer natural gas from an isolated segment into another part of the system, reducing the quantity remaining before final depressurization. Applications can include pipeline commissioning, maintenance, pigging, inline inspection and gas transfer, with MRR coordinating the equipment, connections, pressures, flow conditions and field sequence around the project. Where recovery is technically and operationally practical, retaining gas in the system can reduce product loss and the volume ultimately requiring venting or combustion.

Enclosed Combustion & Final Gas Management

Not every pipeline volume can be economically or technically recovered. Where combustion is appropriate, MRR can incorporate an enclosed combustion system into the gas-management plan to consume natural gas that would otherwise require another approved disposition method, with equipment and operating sequence selected around gas flow, pressure, composition, site area and project requirements. A complete plan may use more than one method - gas transfer or recompression while differential pressure is available, followed by enclosed combustion for residual inventory - reducing unnecessary equipment changes, delays and avoidable gas loss.

MRR can review the pipeline conditions and operating objective to develop a temporary flow, recovery and residual-gas strategy around the project.
