Water injection is one form of engineering technique to enhance oil recovery (EOR).

Used in onshore and offshore developments, water injection involves introducing water into reservoir to encourage oil production.

While the injected water helps to increase depleted pressure within the reservoir, it also helps to move the oil in place. Waterflood sweeps remaining oil through the reservoir to production wells, where it can be recovered.

Halvorsen TECs HRSGs and OTSGs it integral part of Combined Cycles or Combined Heat and Power Cycles.

A Combined Cycle (CC) power plant consists of
 – one or more gas turbines
–  steam generator(s) in the gas turbine exhaust
– one (or more) steam turbines
–  condenser system
–  condensate and feed water pumps
–  various ancillary systems

Water or Steam Injection in Gas Turbines will reduce NOx formation and with steam injection power and efficiency will also increase.

 In a steam injection scheme, no steam turbine is required. The increased power is caused by the volumetric effect of expanding steam in the gas turbine.

 For both water and steam injection, ultra-pure water is required. As the water is lost through the gas turbine exhaust, the water needs to be continuously produced.

Halvorsen TEC offers equipment to enable enhanced power production and efficiency in gas turbines without using steam turbines.

The duty and efficiency of a gas turbines can be increased by injecting Superheated Steam into the combustion zone of the gas turbine.

Since the water is “consumed” as it is lost together with the exhaust of the gas turbine, ultra-pure water needs to be continuously produced.

Halvorsen TEC deliver WHRUs to our clients overall WHRU systems.
