Invitation to Bid for the Engineering, Procurement, Installation and Commissioning of a New Air Separation (Nitrogen) in Warri Refining and Petrochemical Company Limited (WRPC)

Warri Refining and Petrochemical Company Limited (WRPC)

A Subsidiary of Nigerian National Petroleum Corporation (NNPC) 

Invitation to Bid for the Engineering, Procurement, Installation and Commissioning of a New Air Separation (Nitrogen) in WRPC


Warri Refining and Petrochemical Company Ltd (WRPC) has two (2Nos.) cryogenic Nitrogen Plants with a combined capacity of 1850Nm3/hr of gaseous Nitrogen. The smaller of the two units have been out of service for some years due to faulty compression/refrigeration equipment and control systems. Also, progressive loss in Cold Box thermal insulation properties has adversely reduced Nitrogen production rate from the only functional Nitrogen Plant.

In order to restore Nitrogen availability to adequately meet demands for inert gas and other process requirements, it is necessary to build a new Air Separation Plant that will produce Nitrogen.

Purpose of the Project

The Nigerian National Petroleum Corporation wishes to install a cryogenic Nitrogen Plant with the following characteristics:

Cryogenic Nitrogen plant:

(A)    Design Capacity: 950 Nm3/hr  Gaseous Nitrogen production

(B)     Design Network distribution pressure: 7.5 Kg/cm2 g

(C)     Design Nitrogen purity: 99.9995%

(D)    Design oxygen content: 5ppm vol max

(E)     Design Dryness:-70°C dew point

(F)     Design liquid nitrogen pressure @ cold-box outlet: 7.5 Kg/cm2 g


(A)    Design vaporization capacity: 700 Nm3/hr Gaseous Nitrogen production

(B)     Design Network distribution pressure: 6 – 7Kg/cm2 g

(C)     Design Temperature: 5°C min

  •  Volume flow rates, Nm3/hr refers to conditions at 273K temperature and pressure of 760mmHg

Scope of Work

The scope of work includes but not limited to the engineering, design, procurement and delivery of equipment and materials including special tools, construction and installation, inspection, pressure testing, radiography, pre-commissioning/Commissioning, Operator training, start-up and acceptance testing after mechanical completing and hand-over of a new Air Separation Plant for production of Nitrogen. The works shall entail both mechanical, civil, electrical and instrumentation and control components. Provision of 2 years spare parts for key equipment and units of the new Air Separation Plant such as Main Process Air Compressor, ozone layer-friendly Refrigeration Unit, Dryer/Adsorber Units, Cold Box, etc.
