OIL & GAS

Although the individual processes are not as complicated as refinery processes, the dynamic and shutdown / startup issues are complex, especially in remote locations. A thorough understanding of these issues for startup and shutdown, manned and unmanned facilities, emergency control and overpressure protection, black startups, compressor train balancing and many other issues are provided by our team.

PROCESS is able to provide a number of standard services to upstream processors for both Onshore facilities as well as Offshore.

PROCESS can help with the following common issues in all areas of upstream processing.

UPSTREAM OIL AND GAS PROCESSING

Oil/Gas Separation

Flaring reduction/elimination

Hydrate prediction and prevention

Glycol dehydration

PETROLEUM REFINING

PROCESS provides a wide range of engineering services to petroleum refineries. Our company has a great deal of refinery unit design, process safety, operations, and troubleshooting experience. After proving ourselves on smaller sized projects, many of our clients begin utilizing our services on a routine basis as an extension of their own in-house engineering team. From solving a vapor-locked pump problem to designing complete units, PROCESS can meet your needs.

OUR REFINING NICHE

PROCESS can provide preliminary design packages, Heat & Mass Balances, process and equipment design packages, and any number of front-end related services. This is true for most typical refinery processes, a few of which include:

Crude Units
Vacuum Distillation Units
Hydrotreating
Isomerization
Fluid Catalytic Cracking
Reforming
Coking
Visbreaking

We have worked on a broad base of refinery projects for many years, and that breadth allows us to rapidly respond to our clients’ needs with quality information and reliable front-end design packages. A few of the project types completed by PROCESS AND MECHANICAL have included:

Capacity Evaluations
Unit Debottlenecking
Fractionation Upgrade Design
Capital Project Development Support (FEL-0, 1, 2, 3)
Unit Simulation and Modeling
Energy Usage Improvements
Flare Header Studies
Relief Valve Sizing Validation
Balance of Process Design for New Technology Deployment
and more….

PROCESS is also able to provide a qualified 3rd party evaluation of refinery unit design packages and we are very adept at conducting unit capacity evaluations and revamp studies, utility evaluations, small to medium sized process designs, relief valve studies, and almost any refinery process safety related function.

PROCESS can also provide expert consulting services and bid evaluations on larger projects that may require additional resources. Examples of such larger projects would include reviewing the design package for a new Fluid Catalytic Cracker (FCC) unit or Hydrocracker.

LNG SYSTEMS EXPERIENCE

LNG facilities utilize a number of challenging compression and refrigeration systems. Dynamic simulation (dynamic compression evaluation programs) help ensure systems are protected and adequately designed for frequent start up and shut down under a variety of load conditions. Here are some examples of common LNG subsystems:
Process Systems
Pipelines
Condensate separation
Benzene removal
CO2 Absorption
Driers
Mercury absorption
Pre-cooling
Heavy hydrocarbon columns
Liquefaction
Sub-cooling
CO2 liquefaction/re-injection
LNG storage/loading
LPG fractionation/storage
Refrigerant makeup
Mono-ethylene Glycol (MEG)
Gas turbines and electrical (plus emergency power)
Compressed air
