OPD offers consulting services designed to aid our clients in evaluating the feasibility of proposed projects.
OPD provides clients with detailed engineering packages in all disciplines, including 2-D design drawings and 3-D models and renderings.
OPD provides single point procurement of all equipment, materials, and construction services necessary to fabricate and construct our clients' projects. Our large Katy warehouse provides a central storage and distribution point aiding in overall project logistics.
Our 33,000 sq. ft. fabrication shop and 20-acre site support fabrication of structural steel, carbon steel, and alloy pipe spools, as well as ASME coded vessels (U&R stamps).
Our field crews perform all phases of field construction from initial site work to start-up.
From NGL recovery to liquids processing and petrochemicals, every project – and every client – has our full attention.
Each plant design is chosen to meet the specific requirements of the client, from high ethane and / or high propane recovery to hydrocarbon dew point control.
OPD offers custom solutions to all gas and liquid treating problems, including removal of Co2, H2S, mercury, sulfur compounds, oxygen, nitrogen, BS&W, and other contaminants.
OPD offers a wide range of applications to meet gas and liquid dehydration requirements including Mol Sieve, TEG, and Silica gel.
OPD designs and constructs both steam and heat medium systems utilizing various heat transfer fluids. These systems are designed based on specific needs of the process.
OPD designs, constructs, and installs waste heat recovery systems for both gas turbines and reciprocating gas engines.
OPD solves all your NGL fractionation needs from new facilities to de-bottlenecking of older units. Designs vary from one tower to multiple towers as required.
OPD offers complete process design and construction of block mounted or skid-mounted stabilization systems, to produce Y-grade and / or RVP condensate products.
OPD provides complete system design and installation for our client's gas and refrigeration compression requirements.
OPD has years of experience using propane refrigerant in the process design, mechanical design, and construction of dew point control plants, straight refrigeration plants, refrigerated-JT plants, and cryogenic plants. OPD has installed reciprocating compression, centrifugal, and oil-flooded screw compression for propane refrigeration systems. OPD has the experience and knowledge to employ other refrigerants as required.
OPD can develop plant designs using proprietary processes for NGL recovery. OPD also has working relationships with major licensors for other gas and petrochemical processes.
