Cryogenic Nitrogen Generation Plant - 6600 Nm³/h

Stock # 600
Capacity 6600 Nm3/hr
Products High Purity Nitrogen

Overview

Unused, never installed semi-automated cryogenic nitrogen generation plant, designed for ultra-high purity gaseous and liquid nitrogen. Built in 2024. Consisting of (2) TGN-3700 Nitrogen Generators, each train produce 3,332 Nm³/h of gaseous nitrogen rated 115 PSIG at 0°C. Nitrogen Generators & Cold Box Designed by Cosmodyne. Plant delivers nitrogen with extremely low impurity levels: oxygen at a maximum of 3 ppm, moisture at 3 ppm, total hydrocarbons (THC) at 1 ppm, carbon dioxide at 0.5 ppm, carbon monoxide under 1.5 ppm (with incoming air CO < 450 ppb), and hydrogen below 1.0 ppm (with incoming air H2 < 280 ppb). Each plant consumes 1,700 kW of connected electrical power (1,380 kW during operation). Cooling Water System utilizes 715 GPM of cooling water with an 8°C temperature rise and 60 Nm³/h of instrument air at 80 PSIG. The plant includes a backup provision of 207 Nm³/h of liquid nitrogen supply during turboexpander downtime. Integrally geared centrifugal multi-stage air compressors are manufactured by Ingersoll-Rand, driven by TECO electrical motors. Air treatment includes adsorption via activated alumina in vertical carbon steel vessels with molecular sieve support, cooled using a screw-type chiller by Nikkiso utilizing R134A refrigerant. Cryogenic separation is executed within a Cold Box constructed of aluminum pressure vessels and internal piping, featuring aluminum plate-fin heat exchangers manufactured by Chart. A radial inflow turboexpander (model TC Series) by Nikkiso. Allen-Bradley ControlLogix PLC controls integrated with Rockwell FactoryTalk HMI software. The backup system includes two 15,000-gallon vertical liquid nitrogen (LIN) storage tanks (Chart), four ambient vaporizers for backup and one for startup (Cryoquip, SG770HF), and a 15,000-gallon startup LIN tank.
