Common Applications for DPC Equipment:

• Meet transporting pipeline hydrocarbon dew point specifications.
• Capture NGL liquid upgrade income.
• Capture additional income by removing the "crude" component prior to NGL processing to avoid processing, transportation, fractionation and marketing fees.
• Controlling gathering system liquid drip for efficiency and safety reasons.
• Improve measurement volumes recorded by orifice custody transfer meters by removing the liquid buildup on the orifice plates.
• Prove the potential of new gathering systems prior to the capital commitment of the deep liquid NGL recovery facility.
• Short term lease to move gas to market during the construction phase of a deep liquid recovery NGL facility.
• To provide additional short term capacity to a deep NGL liquid recovery facility by conditioning gas that bypasses the existing facility or leaning the NGL component of the gas entering the NGL liquid recovery facility.

DPC leases three sizes of refrigeration units:

• Model B2-R - 5 to 25 MMSCFD
• Model CB-R - 15 to 50 MMSCFD
• Model C2-R - 15 to 50 MMSCFD

The DPC refrigeration station provides a simple, cost effective, easily operated method for hydrocarbon dew point control. 

DPC leases four sizes of JT units:

• Model A - 1 to 6 MMSCFD
• Model B - 5 to 15 MMSCFD
• Model C - 12 to 25 MMSCFD
• Model D - 20 to 50 MMSCFD

Unit capacities are dependent upon operating pressures, temperatures and gas compositions. The volumes given above are only a general representation of the operating ranges of these units.

JT units are commonly used to hydrocarbon condition small volume streams of natural gas and to take advantage of situations when excess gas pressure is available.
