Suitable where greater liquid hold-up, residence time or multi-phase separation is required.
Used in: Phase Separation · Gas Conditioning · Oil Processing

Suitable for gas-dominated duties or applications where plot space is limited.
Used in: Gas Conditioning · Hydrocarbon Recovery · Oil Processing

A pressure vessel fitted with internals to separate gas, hydrocarbon liquids and water, in two-phase or three-phase configurations.
Used in: Phase Separation · Oil Processing

A tall vessel fitted with trays or packing, selected where gas and liquid need staged contact for mass transfer.
Used in: Gas Conditioning · Hydrocarbon Recovery · Oil Processing

Brings gas into contact with a liquid such as amine or glycol to remove acid gases or water vapour.
Used in: Gas Conditioning

Removes lighter components from hydrocarbon liquids using heat or stripping gas, for example to stabilize crude oil or condensate.
Used in: Oil Processing · Hydrocarbon Recovery

Transfers heat between process streams while keeping the fluids physically separated.
Used in: Gas Conditioning · Hydrocarbon Recovery · Oil Processing

Supplies heat to generate vapour at the base of a column or in a glycol or amine regeneration circuit.
Used in: Gas Conditioning · Oil Processing

Removes heat from a process stream or condenses vapour to liquid; air-cooled designs use ambient air as the cooling medium.
Used in: Hydrocarbon Recovery · Gas Conditioning · Oil Processing
SPEC can integrate equipment into skid-mounted, multi-module or field-assembled process systems according to project requirements.

Combines equipment, piping, valves and instrumentation on one structural base, allowing workshop assembly and transport as a single unit.
Used in: Multiple process applications

Integrates measurement and flow-control equipment into one structured assembly for gas or liquid metering duties.
Used in: Gas and liquid handling applications

Divides a larger process system into transportable modules connected at site, used where one skid would be too large to transport.
Used in: Larger process facilities
