TCE Response for Combating COVID

Engineering Solutions to Combat Challenging Times

The pandemic second wave required urgent actions towards enhancing the country's Oxygen generation and distribution capacity. Tata Consulting Engineers Limited (TCE) has made sincere efforts towards contributing to the requirement, focusing on Agility and Indigenisation aligned to Atmanirbhar Bharat, Quality and Cost Competitiveness.

In the second wave of COVID19, India witnessed a massive shortage of medical oxygen in hospitals. Even though oxygen used for industrial purposes was diverted for medical use, it was not enough to meet the increasing demand. Alternative modes of oxygen generation were required considering the colossal demand, especially at remote locations.  Therefore, there was a need to look for additional sources through which oxygen could be generated quickly near the consumption point. A task force was set up at Tata Consulting Engineers (TCE) to study all possible options and work on engineering the fastest and best-suited option in the given circumstances.

Alternate and out of box solutions for storage and distribution of oxygen were investigated and published as the whitepaper, including conversion of CO2 fire extinguishers and LPG cylinders for medical oxygen service. All these methods involve statutory, legal and other approvals. They must be done with the proper involvement of government authorities. Adequate cleaning and colour coding of the cylinders are required for safety reasons. A governance mechanism involving government officials, PESO, Controller of Explosives, Fire Department, Medical Department (Min. of Health) and administrative authorities is also required for related compliances and approvals.

Indigenous Opensource Oxygen Concentrator Design

With COVID patients requiring between 5-20 LPM and keeping in mind the need for such devices in villages and interior parts of the country, TCE targeted the specification for up to 20 LPM designs. The prototype leveraging opensource design ( was accomplished in less than five (05) working days, with complete local parts as available in India (except Zeolite) and with benchmark results of 10-20 LPM of 90-95% oxygen concentration. Necessary design changes and process refinements were incorporated to ensure benchmark results under Indian conditions. Read More...

Conversion of Existing PSA Nitrogen Plants for the Production of Oxygen: 75+ Nitrogen Plants Under Conversions

A new ‘Pressure Swing Adsorption (PSA) oxygen generation plant typically takes about eight months. PSA nitrogen plants were already installed and operational in many industries for industrial purposes. Given the COVID19 induced oxygen emergency, conversion of existing PSA nitrogen plants for oxygen production emerged as the most practical solution in the given situation. Read More...

Explore Use of CO2 Fire Extinguisher and LPG Cylinders for Medical Oxygen

The cylinders are the last mile connectivity between oxygen production facilities and the hospitals’ patient beds. Various alternative means for storing medical oxygen are being explored. Plenty of fire extinguishers are already available and in use across all the locations, be it offices, malls, theatres, residential complexes, etc. Since offices, malls, theatres are not in operation, and people are working from home, every city already has the availability of these storage devices.

These fire extinguishers can be used without worrying about fire safety as buildings are not occupied. Moreover, these are lightweight, easy to transport, and quick to fabricate in bulk. They can be potential candidates for converting and utilising for storing medical oxygen during emergencies like the COVID19 pandemic. Some essential considerations for checking the suitability of CO2 fire extinguisher cylinders as medical oxygen cylinders include confirming its pressure rating specifications, the material of construction, and the available cylinder’s capacity.

Standard Tata Unit: Modular Health Facility for COVID-19

To meet the COVID19 challenge requiring urgent strengthening of health infrastructure, Tata Consulting Engineers (TCE) and its subsidiary Ecofirst designed a ‘ready to implement’ modular health facility. Each module is equipped with air-conditioning, five beds and one toilet. This ready to use design can be implemented immediately as an extension of an existing hospital or a completely new COVID19 hospital anywhere in India. These modular units put together can expand to any number of beds, are self-sufficient, sustainable, and can be easily repurposed or dismantled in the future.

The design of these modular units incorporates inputs received from medical planners, COVID doctors, virologists, architects, HVAC and ventilation experts. Tata Consulting Engineers shared these designs freely with many implementing or donor agencies for immediate use.Read More...

Supported PSA Plants with Sourcing of Zeolite from Europe and Technical Knowhow: 89+ New Oxygen Plants

While creating the prototypes and pilots, Tata Consulting Engineers (TCE) realised the acute shortage of a vital component, Zeolite, to convert PSA Nitrogen plants to produce Oxygen. The same is also required for installing new oxygen plants.

TCE partnered with Tata Chemical for the required sourcing of Zeolite from Europe. With the support of the Ministry of Commerce, PSA, DSIR & CSIR, we received GOI – IAF support for urgent airlifting of this critical resource to convert and install new oxygen plants.

With the support of Tata Chemicals and Central Pollution Control Board, TCE created a process of due diligence and project managed the allocation of this raw material to more than 65 plants, ensuring timely availability of the essential resource at an affordable price.

TCE teams are assisting various Central efforts, State Governments, Startups, NGOs and Hospitals on all of the above topics and are also providing consultancy for new PSA Oxygen plants, hospital oxygen infrastructure, pipelines and related checklists and audits. TCE has responded to more than 3000+ requests for information and support.

Oxygen Ventilator

An engineering, feasibility and viability study was conducted on multiple ventilators, and a viable open source ventilator was identified. The learnings were shared with group entities for evaluation, and appropriate next steps were suggested for mass manufacturing related tie-ups.

Multiple Ventilator design were studied for feasibility under emergency conditions (No prototypes were created, only feasibility evaluations and recommendation made)

OpenSource Medtronics Ventilator was finally zeroed upon, and manufacturing firms were conveyed to explore tie-up and manufacturing
