Reconstruction of gas compressor unit GPA-Ts-16
The GPA-C-16 gas turbine pumping unit retrofit is conducted by substituting the NK-16SТ engine for the GTU-16PC gas turbine, and by including an appropriate hardware for upgrading the gas pumping set systems.

Description
GTU-16PC gas turbine with a hardware set is installed on the existing foundation, into an existing enclosure with the improved GPA-C-16 gas pumping systems. The hardware set provides the upgrading of gas compressor systems for the GTU-16PC installation, and also, replacement or upgrading of out-of-date or worn-out systems of the unit. The replacement is to be determined by a specification approved by the Customer.
GTU-16PC is a modification of the GTU-16P gas turbine designed for modular version of the GPA-16 "Ural" gas turbine pumping set in the scope of the Complex Program "Ural-Gazprom" for the development of gas pumping units and gas turbine power stations of new generation.
Differences of GTU-16PC from the base design are determined by specific conditions of tie-in, lay-out and necessity to design (upgrade) the connecting points of a renovated gas turbine pumping unit. The philosophy of NK-16ST retrofit is the maximum use of existing systems of the set.
To optimize the GPA-C-16 gas turbine operation conditions, it is possible to replace the NK-16SТ engine (16 MW power) with the GTU-12PC (modification of the 12 MW GTU-12P gas turbine) and to change the replaceable gas-flow path of the gas compressor.
Automatic control unit (ACU) is based on МSКU-SS 4510-38-08-01, and common with gas pumping systems and gas turbine mechanical drive systems.
Primary Performance Data
ISO Conditions, loss-free, fuel: Methane (LHV=11958 kCal/kg)
Power turbine shaft output, MW 16.47
Efficiency at power turbine shaft, % 37.0
Exhaust gas temperature, °С 466
Output speed, rev/min 5 300
Exhaust gas flow, kg/s 57.2
Service life:
-overhaul interval, hr 25 000
-design life, hr 100 000
Advantages
The retrofit of GPA-C-16 with application of NK-16СТ in GTU-16PC gas turbine and new hardware allows to improve the unit performance, that is:
to improve driven engine reliability;
to improve reliability of the modified systems;
to reduce the consumption of fuel gas;
to reduce irretrievable losses of lube oil;
to improve the ecological characteristics.
The retrofit is carried out with maximum use of existing systems of the set.
