In the production of oil and gas, there are several by-products produced, one of which is water. Water creates a problem in that as pressure is released from the gas it causes a refrigeration effects which causes the water to freeze stopping the flow of the gas. For this reason, methanol is injected into the production lines or glycol heat tracing is used to prevent hydrates and ice plugs from forming.

Water production occurs in virtually every gas well. The longer the well is in production, the higher the water content becomes. The faster the rate of production, the higher the water content becomes.

A typical chemical injection pump is a piston type positive displacement pump that is attached to a large diaphragm type motor. These pumps work in a similar way to the steam engines of the past. Rather than using steam as a driving force, these pumps use either natural gas from the well's production or in the case of sour gas wells purchased propane or sweet gas. These pumps then exhaust these gases to the atmosphere during their operation in the same fashion as steam engines exhaust steam during their operation.

The production of oil has similar emission problems as the production of gas due to the volume of entrapped methane in the oil stream.

Where a few oil wells are directed to a central location called a battery or satellite, methanol is introduced into the flow line before being directed to the main processing facility.

Under current pumping practices, the circulation of glycol in a dehydration system produces an unacceptable volume of raw emissions to the atmosphere. The EnviroDrive™ system addresses this problem through its unique method of returning the drive gas back into the process system after using it as the drive medium to circulate the high pressure glycol required for dehydration thus saving the gas for sale.

The EnviroDrive™ system can also be used to eliminate the harmful emissions caused by control systems which use natural gas as a pressure source. An EnviroDrive™ system utilizing a generator or a air compressor to operate control systems will achieve zero emissions at the well site.
