1. The first cryogenic 50m3 cryogenic oxygen production equipment in Ethiopia
50 cubic meters of cryogenic oxygen was shipped to Ethiopia in December 2020. The equipment, the first of its kind in Ethiopia, has already arrived in the country. Under construction and installation.




2. PSA oxygen generator
Various oxygen suppliers in Peru asked our company to purchase several PSA oxygen generators and oxygen cylinders.




3. Workshop
Our precision designing makes our industrial gas systems reliable and efficient resulting in low operational costs. Being manufactured with high quality materials and components, our liquid oxygen plants lasts for a very long time requiring minimum maintenance. For our compliance with strict quality control measures, we have been awarded with acclaimed certifications like ISO 9001,ISO13485 and CE.

2.Fully automated system for simple and reliable operation.
3.Guaranteed availability of high-purity industrial gases.
4.Guaranteed by the availability of product in liquid phase to be stored for use during any maintenance operations.
5.Low energy consumption.
6.Short time delivery.



Application Fields
Oxygen, nitrogen, argon and other rare gas produced by air separation unit are widely used in steel, chemical industry,refinery,glass, rubber, electronics, healthcare, food, metals, power generation and other industries.

Product Specification
1. Design principle of this plant is based on the different boiling point of each gas in the air. Air is compressed, precooled and got removal of H2O and CO2, then to be cooled in the main heat exchanger until it is liquified. After rectification,production oxygen and nitrogen can be collected.
2. This plant is of MS purification of air with boosting turbine expander process. It is a common air separation plant, which adopts complete stuff filling and rectification for argon making.
3. Raw air goes to air filter for removal of dust and mechanical impurity and enters air turbine compressor where air is compressed to 0.59MPaA. Then it goes into air precooling system, where air is cooled to 17 ℃. After that, it flows to 2 molecular sieve adsorbing tank, which are running in turn, to be got removal of H2O, CO2 and C2H2.

* 1. After purified, air mixes with expanding reheated air. Then it is compressed by middle pressure compressor to be divided into2 streams. One part goes to main heat exchanger to be cooled to -260K, and sucked from the middle part of main heat exchanger to enter expansion turbine. Expanded air returns to main heat exchanger to be reheated, after that, it flows to air boosting compressor. The other part of air is boosted by high temperature expander, after cooling, it flows to the low temperature boosting expander. Then it goes to cold box to be cooled to ~170K. Part of it would still be cooled, and flows to bottom of lower column via heat exchanger. And other air is sucked to low tempt. expander. After expanded, it is divided into 2 parts. One part goes to the bottom of lower column for rectification, the rest returns to main heat exchanger, then it flows to air booster after being reheated.
2. After primary rectification in lower column, liquid air and pure liquid nitrogen can be collected in lower column. Waste liquid nitrogen, liquid air and pure liquid nitrogen flows to upper column via liquid air and liquid nitrogen cooler. It is rectified in upper column again, after that, liquid oxygen of 99.6% purity can be collected at the bottom of upper column,
and is delivered out of the cold box as production.
3. Part of argon fraction in upper column is sucked to crude argon column. There are 2 parts of crude argon column. The reflux of second part is delivered to the top of first one via liquid pump as reflux. It is rectified in crude argon column to get 98.5% Ar. 2ppm O2 crude argon. Then it is delivered to the middle of pure argon column via evaporator. After rectification in pure argon column, (99.999%Ar) liquid argon can be collected at the bottom of pure argon column.
4. Waste nitrogen from top of upper column flows out of the cold box to purifier as regenerative air, rest goes to cooling tower.
5. Nitrogen from top of assistant column of upper column flows out of cold box as production via cooler and main heat exchanger. If no need nitrogen, then it could be delivered to water cooling tower. For cold capacity of water cooling tower is not sufficient, a chiller needs to be installed.

         PSA NITROGEN GENERATOR
PSA nitrogen generation adopts carbon molecular sieve as adsorbent whose capacity of adsorbing oxygen is larger than adsorbing nitrogen. The two adsorbers (a&b) alternately adsorbing and regenerating to separate oxygen from nitrogen in air to obtain purified
nitrogen by Auto-operated valves controlled by PLC.





PSA Oxygen Generator

* Fully automated- systems are designed to work unattended.
* PSA plants are compact taking little space, assembly on skids, prefabricated and supplied from factory.
* Quick start-up time taking only 5 minutes to generate oxygen with desired purity.
* Reliable for getting continuous and steady supply of oxygen.
* Durable molecular sieves that last around 12 years.




 
    Membrane Nitrogen generator 
Membrane separation nitrogen production technology is currently one of the most advanced room temperature air separation technologies in the world. The principle is to use the difference in the permeability of each component gas in the air through the separation membrane to achieve the purpose of nitrogen and oxygen separation




VPSA OXYGEN GENERATOR
PSA oxygen generator uses zeolite molecular sieve as the adsorbent, and uses the principle of pressure adsorption and decompression desorption to adsorb and release oxygen from the air, thereby separating oxygen from the automatic equipment. N2 molecules have a faster diffusion rate in the micropores of zeolite molecular sieve, and O2 molecules have a slower diffusion rate.
