SIAD MI’s HDS2-1 nitogren compressor

SIAD Macchine Impianti (SIAD MI) has recently completed the construction of a horizontal nitrogen compressor, which will be supplied to Technip Energies Italy. The compressor, which has passed the test and inspection phases at the SIAD MI factory, is destined for a new hydrocracking unit at the Assiut National Oil Processing Company (ANOPC) in central Egypt.

This plant will enable the supply of high-grade oil products, minimizing atmospheric emissions and maximizing the production of LPG, high-octane naphtha, low-sulfur diesel and aviation fuels. The new refinery wants to reduce the ecological impact of hydrocarbon refining processes while maintaining high production standards.

In this project, the nitrogen compressor will be used for gas circulation not only within the hydrocracking unit but also between the desulfurization section, the catalytic reforming unit and the HPU (Hydrogen Plant Unit).

Like all the compressors in the SIAD MI range, the nitrogen compressors are also customized on the basis of process data and technical specifications provided by the customer: in this case SIAD MI designed a special single-stage compressor with two horizontal cylinders in oil-free configuration, model HDS2-1. The compressor will be driven by a 760 kW motor.

The horizontal compressor will be installed onto a concrete foundation rather than a pre-assembled metal base. In addition, the critical components in contact with nitrogen, such as piston rings and seals, have been carefully selected to allow the compressor to operate in maximum safety, minimizing maintenance interventions, SIAD MI said.
