Compression recovery device for delivering electricity in pipeline systems

A pipeline system for transporting hydrocarbon gas comprising:

• a compression recovery device comprising:
• an inlet configured for coupling to an upstream pipeline of the pipeline system and an outlet configured for coupling to a downstream pipeline of the pipeline system;
• a turbine including turbine blades;
• a turbo housing coupled to the inlet and the outlet and comprising a hollow passage configured to route fluid flow to a side of an axis about which the turbine blades of the turbine spin;
• the turbine coupled to an alternator through one or more couplings that extend above and away from the pipeline system, the alternator configured to output electricity upon spinning of the turbine blades caused by flow of fluid through the pipeline system;
• an electric powered device coupled to the compression recovery device;
• an air-tight outer housing covering the compression recovery device;
• and
• a remote substation that is not coupled to an electrical grid;
• wherein the compression recovery device is coupled to the pipeline system at the substation where pressure is dropped from the upstream pipeline to the downstream pipeline.

A method of generating electric power at a remote pipeline location, comprising the steps of:

• spinning a turbine of a compression recovery device with fluid flow through a turbo housing;
• converting the spinning of the turbine to electrical power without causing an eddy current acting on the turbo housing;
• sending the electrical power to power one or more devices selected from:
• a sensor, a motor to power a valve opening and closing, a pre-heater, or computing equipment;
• wherein the fluid is a gas hydrocarbon;
• wherein an air-tight outer housing covers the compression recovery device;
• and
• the remote pipeline location is not coupled to an electrical grid;
• wherein the compression recovery device is coupled to a pipeline at the remote pipeline location;
• and pressure is dropped from an upstream pipeline to a downstream pipeline at the remote pipeline location.
