Oil & Gas Processing Plants

Page Contents

HMC has entered into collaboration arrangements with several leading Design/Engineering companies of the world specializing in various Process Technologies for different Oil and Gas processing plants and Production Equipment. HMC’s technological archives are in possession of the ‘State of Art’ in process and manufacturing technologies of the various gas processing plants and equipment. As a consequence of development of HMC’s capabilities in the field of oil & gas, processing plants equipment are now regular production items in our manufacturing program.

Our products for oil and gas industry include:

  • Gas dehydration plant.
  • Gas sweetening plant.
  • Sulphur recovery plant.
  • LPG/NGL recovery plant.
  • Crude stabilizing plant.
  • Oil, gas & water separators. (Two phase & Three phase)
  • Pressure Vessels of different sizes and parameters
  • Cementing equipment.
  • Storage tanks. (LPG, Diesel, Crude oil, Water etc.)
  • Heat Exchangers (Shell & Tube, Air cooled, Double pipe)
  • Columns
  • Mud Solution Tanks.
  • Off-site facilities and utilities.

Equipment supplied by HMC conform to API/ASME standard specifications and is offered with the guarantees and warranties in accordance with the international practices. HMC has been authorized for ASME Code Stamps for pressure vessels and pressure piping.

AMINE PLANTS

Gas volumes which can be processed in these plants depend on the amount of acid gas in the inlet gas streams.

Standard plants allow use of MEA, DEA, MDEA, DGA or other liquid solvents to remove acid gas. Each packaged, skid-mounted system includes all piping, instrumentation, and electrical components required. Field installation and hook-up can be handled quickly with assistance from HMC field personnel if desired.

Amine plants needed to fulfill non-standard operating requirements can be custom-engineered.

GLYCOL DEHYDRATION SYSTEMS

HMC designs, engineers, fabricates, and installs Glycol Dehydration Systems, and provides complete service and maintenance contracts.

The Process

In contractor towers pure glycol flows downward over special bubble-cap trays while wet gas flows up through the tower. The system removes the water to meet pipeline specifications, as low as 1 lb/MMCFD Dehydrated gas leaves the tower ready for transport or additional processing. Wet glycol is filtered off impurities, the water distilled out, and the glycol is recycled to the contractor for system in operation.System capacities in standard and custom sizes range from 20-200 MMCFD. Standard Stream Line units are available. Systems for large gas flow rates or for other specified conditions are custom-engineered.

SULPHUR RECOVERY SYSTEMS

Minimize SO2 Emissions From Amine PlantsHMC provides Packaged Sulphur Recovery plants. On all plants, water-cooled surfaces help prevent corrosion caused by high-temperature sulfiding.

External insulation is provided, where needed, to maintain vessel-wall temperatures above the water dewpoint of the process gases; this greatly reduces corrosion caused by water condensation.

Equipment and piping are self-draining to prevent operational problems caused by sulphur solidification. A 95-plus percent recovery level is readily achieved. Package components vary, depending on the concentration on H2S in the process stream and the degree of sulphur recovery required.

OIL AND GAS SEPARATION

Oil and gas separator is basically simple. Nearly every competitive make operates in a similar manner, but little differences can create the margin between profit and loss, trouble-free operations and quick obsolescence and long service life.

The well stream – a mixture of liquids and gases, enters at one end. The mixture abruptly slows down and settling begins. Natural separation takes place in slow-moving stream because of gravity segregation. The heavier liquids settle to the bottom of the vessel where they are withdrawn. The lighter gas rises to the upper portion of the vessel and is removed through a suitable opening. The removal of oil and water from the bottom is controlled by liquid level controllers that will keep the mixture in the vessel long enough for complete separation of the phases

LIQUIFIED PETROLEUM GAS (LPG) STORAGE TANKS

HMC is manufacturing 01 to 100 ton capacity LPG storage tanks with operating pressure 250 psi and temperature 45oC. LPG tank is supplied complete with all accessories.
