DEXPRO™ PATENTED TECHNOLOGY
DEXPro™ dehydrates acid gases in natural gas processing. Natural gas water content dehydration criteria may be too stringent for commonplace acid gas systems. DEXPro™ ensure the correct level of water removal, minimal energy usage, and operational simplicity DEXPro™ units can usually replace existing refrigeration or triethylene glycol (TEG) units.
The DEXPro™ system integrates into the design of the compressor to allow for maximum compressor performance and water dropout while minimizing hydrate formation, and keeping the system footprint small.
The DEXPro™ process takes advantage of the relatively high Joule-Thomson coefficient characteristic of acid gas and utilizes precision control of pressure and temperature to achieve gas dehydration. Existing compression equipment combines with the DEXPro™ process to create an “auto-refrigeration” environment to cool the acid gas and condense the water and hydrocarbon liquids (in EOR applications).
THE DEXPRO METHOD
Facilities usually need to dehydrate acid gases prior to pipeline transport to minimize the risk of forming hydrates which (through condensation) may promote corrosion and operational challenges in piping or pipelines. The DEXPro™ process is simple and can be easily incorporated into existing compression systems, resulting in reduced capital costs. The main DEXPro™ process has no rotating equipment and no contaminating chemicals, which lowers the risk of unplanned maintenance or decontamination. These advantages significantly lower operating costs.
TECHNOLOGY PROCESS
STEP 1
The DEXPro™ patented process uses a TCV or JTV (Joule-Thomson Valve) and cools a stream of high-pressure dry acid gas by reducing the pressure, thereby expanding and cooling the gas.
STEP 2
The DEXPro™ Module mixes cool dry acid gas with wet acid gas to condense water from the wet acid gas stream.
STEP 3
The mixed stream is cooled enough to condense water and hydrocarbons out of the stream, which are collected in the downstream separator and/or suction scrubbers. These liquids are extracted and sent to storage or disposal.
STEP 4
Cool dry gas increases efficiency in the following compression stage.
REDUCE
OPERATIONAL
COSTS
Reduce operating and capital costs with the DEXPro™ dehydration system, which has minimal parasitic load with no fugitive emissions, no vapour recovery unit, and no ongoing chemicals requiring regeneration or handling.
THE DEXPRO ADVANTAGE
DEXPro’s™ dehydration process has many advantages over traditional dehydration systems. It is the most cost-effective and sustainable option on the market and plays an important role in net-zero scenarios and decarbonization commitments for both government and business. The DEXPro™ advanced dehydration process for enhanced oil recovery (EOR) can also provide a new revenue stream (for EOR applications). DEXPro™ is the only dehydration system on the market that can grow revenue while maintaining operational efficiency.
Since the DEXPro™ process can be incorporated into existing equipment, the need for additional capital expenditures is minimized. The DEXPro™ team of industry experts seamlessly integrates the DEXPro™ technology into an established facility design.
Simple Design & Operation.
- It can be provided as a stand-alone skid or incorporated into each compressor.
- It has a small physical footprint.
- There is no specialized training required to operate it.
- There are no hazardous or flammable chemicals in the DEXPro™ process.
- Minimal (or no) operator intervention is required during normal operation.
Low CAPEX & OPEX.
- There is no ongoing chemical regeneration or emissions.
- No masked operations are required, as there are no sour filters to change.
- No waste disposal from spent sour filters or chemicals is required.
- There is no fired equipment to maintain. Doesn’t require a vapour recovery unit (VRU).
- There is no carryover to interfere with instrumentation, maximizing up time for operation.
- There are no fugitive emissions or off-gas handling requirements.
