Control System: Mitsubishi Processor with IO nodes and Graphics Display

Scope of work: The Automatic Liquid Filling System is engineered to minimize losses inherent in traditional filling methods. Employing a “top” filling approach, the system sprays liquid into the vapor phase of the cylinder, optimizing efficiency. This method reduces labor requirements and shortens fill times significantly. Featuring two filling stations, each station’s weight indicator is linked to a Programmable Logic Controller (PLC) via Ethernet communication. The PLC orchestrates the filling process, managing states such as Idle, Cylinder Filling, Cylinder Venting, Pressure High, Fill Stop, Inlet Pressure Low, No Cylinder Pressure, and On Hold. This streamlined system ensures precise control and enhances productivity in liquid-filling operations

End User: Mangalore Refinery and Petrochemicals Limited (MRPL) 

Technical Consultant: Engineers India Limited (EIL) Delhi.

Project Location: BS-VI project (Expansion)

Application: Open Path Gas Detector for H2s Detection.

Technology: 

• Open Path Gas Detection (OPGD): This technology is based on the Beer-Lambert absorption equation and is used to detect the presence of toxic gases like H2S across large areas. It’s particularly useful in industrial environments where these gases might be present due to leaks or emissions¹.
• Detection Technology: The detectors use tuneable lasers to scan a narrow portion of the spectrum, minimizing interference from water vapor and other atmospheric conditions. This allows for fast response times and accurate detection of gas concentrations².

The open path H2S gas detector project seems to be a significant safety initiative, likely related to the Mangalore Refinery and Petrochemicals Limited (MRPL) and their move towards Bharat Stage VI (BSVI) compliance. BSVI is the Indian equivalent of the Euro VI emission standards, aimed at reducing the environmental impact of vehicles.

These detectors, such as the GD1 Laser Open Path H2S Gas Detector by Teledyne GFD, are designed to provide fast, fail-safe detection of H2S gas concentrations in the air¹. They are calibration-free, operate even with up to 98% obscuration, and are suitable for use in systems with Safety Integrity Level 2 (SIL2) requirements². This technology is particularly important in the oil and gas industry, where H2S—a toxic and flammable gas—can pose significant risks to both safety and production

For a project like the one at MRPL, implementing such advanced detection systems would be part of a broader strategy to enhance safety, particularly as the refinery adapts to stricter environmental and safety regulations under the BSVI standards. It’s a proactive measure to ensure continuous monitoring and rapid response in the presence of hazardous gases, thereby protecting personnel and equipment. If you’re looking for more detailed information on the MRPL BSVI project, we would recommend contacting MRPL directly or checking their official communications for updates.

Scope of work: Raja Ramanna Centre for Advanced Technology, Cryognics has a major role to play in both the main fields being pursued at RRCAT viz. accelerators and lasers. Cryogenics is also an essential requirement for conducting experiments with the Synchrotron Radiation Facility at RRCAT in terms of Liquid Nitrogen and Liquid Helium.

The project encompasses the supply, installation, missioning, and testing of instrumentation panels, control room consoles, signal cables, cable trays, a PLC-based system, and large format displays, to facilitate centralized control and monitoring of cryogenic subsystems. These subsystems include Vacuum Pump, Compressor, Vertical Test System, Horizontal Test System, Helium Cylinders, Recovery Compressor, LHe Dewar, Liquification, LR280, Liquid Nitrogen, and Chiller, all seamlessly integrated with the control system.

To ensure comprehensive communication, various protocols are interfaced, including Profibus, ProfiNet, Modbus RS485, and Modbus TCP. This integration of communication protocols enables efficient data exchange and coordination between the different components of the cryogenic system, enhancing operational reliability and control.
