SERVICES

Since 1974 Chemex has engineered and supplied process equipment to major and independent oil and gas producers, refiners and gas processors. Chemex is here to supply your oil and gas processing needs.

Chemex supplies the following deliverables with all equipment.

1. DESIGN
Schedule A Process Design Package

    •    process simulation;
    •    process flow diagram (PFD);
    •    piping and instrumentation diagrams (P&IDs);
    •    electrical single line diagram;
    •    heat exchanger data sheets;
    •    air cooler data sheets;
    •    pump data sheets;
    •    ASME Section VIII pressure vessel data sheets;
    •    electrical and instrumentation equipment lists; and
    •    process unit site plan.

Schedule B Construction Design Package

    •    structural steel design drawings for skids;
    •    equipment general arrangement drawings;
    •    equipment drawings;
    •    piping drawings;
    •    electrical location diagram;
    •    instrumentation location diagram;
    •    electrical wiring diagrams; and
    •    instrumentation wiring diagrams.

2. FABRICATION
Chemex designs its skid-mounted modular equipment for placement on concrete slab foundations. With conventional foundation-mounted equipment, each piece of equipment is placed on its individual foundation and welders pipe the equipment together. This “stick-built” method requires longer construction time than Chemex’s modular process equipment.

Chemex manufactures new and refurbished process units in its shop in Bakersfield, California. Supplying refurbished process equipment with a warranty equal to new equipment is a major share of the business today. Utilizing refurbished process equipment can result in substantial cost savings and accelerated completion schedules when compared with new equipment.

Chemex equipment is designed to be transported by land or sea to any location. The equipment is fabricated in the same configuration as the process unit site plan. All piping, instruments, and electrical connections are made among the skids and tested. After completion of testing, the equipment is disassembled, packed, shrink-wrapped, and shipped.

3. SHIPMENT
All equipment for overseas’ destinations is shipped by truck from the Bakersfield, California fabrication facility to the Port of Houston, Texas. From Houston, the equipment is shipped to the destination port.

4. INSTALLATION
Chemex provides personnel to advise the buyer of the final assembly and construction at each refinery site. Chemex can also provide local project management.

When the equipment arrives at the facility site, it is unloaded and set on the concrete slab foundations. Final skid placement and elevations are checked against the drawings and skids are shimmed and adjusted accordingly. After the equipment is in place, assembly of the interconnecting spools begins. The equipment is literally bolted together. There is very little welding required. The process equipment can usually be assembled and ready to start up within thirty days.

5. COMMISSIONING
Chemex provides advisors for the commissioning of the process equipment. All rotating equipment, instrumentation, and electrical equipment require preparation for operation. Piping is pressure tested and/or vacuum tested. The equipment is purged and made ready for startup.

6. STARTUP
Chemex supplies an advisory crew for the startup of the process equipment.

7. TESTRUN
The twenty-four hour test run confirms the design of the process equipment. Chemex advisors advise the operating personnel about the proper operation of the equipment to achieve the intended results.

Chemex provides design, fabrication, installation, commissioning, and startup for all equipment supplied by Chemex. Equipment includes but is not limited to:

Oil Dehydrators Field Gas Compression Aerial Coolers Heat Exchangers Modular Oil Refinery Catalytic Reformers Sulfur Recovery Plants Natural Gas Expander Plants Asphalt Blenders

Oil/Gas Seperators Amine Treaters Desalters Water Cleaning Units HDS Units Hydrogen Generators Modular Gas Plants LPG Recovery Planst Asphalt Blow Still

Automatic Well Testers Gas Dehydrators Oil & Gas Metering System Atmospheric Distillation Unit (ADU) Vaccum Distillation Unit (VDU) Grass-Roots Oil & Gas Facilities Refrigerated Gas Plant NGL Fractionators PMA Planst

Chemex designs and manufactures new and refurbished process equipment listed above in its shop in Bakersfield, California. Supplying refurbished process equipment with a warranty equal to new equipment is a major share of our business today. Utilizing refurbished process equipment can result in substantial savings in both delivery time and cost.

If you have a process that requires engineering and fabrication, Chemex can do it. Chemex can also fabricate your plant using your fabrication drawings.

Chemex can supply site design and engineering for its clients upon request.
