CASE STUDY
Corrosive Slurries Achieving Clean Emissions with Value Addition
Progressive cavity pumps supplied by Seepex prevented potential problems of reliably moving highly abrasive gypsum slurry and filtrate sludge 24x7 for recovery of spent lime from the wet scrubbers for the state-of-the-art turnkey advanced flue gas desulphurisation (AFGD) facility at coal fired power plant facility. Uninterrupted pumping of slurries helped the plant meet the SOx emission standards with minimum initial investment, economical operation without any disruption in power production ...

Zero liquid effluent discharge system through thermal route
Separation of water can be done by Reverse Osmosis or thermal method. RO is cheaper in terms of operating cost but the life of system is low and replacement cost is high. Mo re importantly RO cannot separate all recyclable water. Whereas, thermal methods involving an evaporator can recover almost all water. Though this method incurs high-energy costs, which however can be substantially reduced by a Multiple Effect Evaporator ...

Checking the Hydrocarbon Gas Leaks
Since the late 80’s Open Path Gas Detection (OPGD) system have been used for detection of cusumbustible gas. Currently, by utilizing Non-dispersive Infrared (NDIR) these detectors have been well accepted to monitor gas leaks at offshore and onshore Oil & Gas production facilities, refineries, petrochemical plants, gas transmission stations and many other industrial facilities...

Air Pollution: Flue Gas Analysis to Monitor Emissions
Flue Gas Analysis is applied to monitor efficiency and emissions in a process with accuracy. Flue gases primarily contain compounds of oxygen and carbon, as fuel and air are the inputs for the combustion process. As the governments get stricter towards noxious gas emissions, it is important to monitor the flue gases released in the environment...

Energy Management: Saving Energy by Waste Heat Recovery: "How and How Much"
Air conditioning / refrigeration systems are designed to remove heat from interior spaces or products and reject it to the ambient (outside) air. Heat rejection may occur directly to the air, as in the case of most conventional air source units, or to water circulating from a cooling tower. The circulating water eventually rejects the heat to the ambient air in the cooling tower. While this heat is of a "low grade variety," it still represents wasted energy. From an energy conservation standpoint, it would be desirable to reclaim this heat in a usable form. The best and most obvious form of heat recovery is for heating water...

Capillary Flow Technology for Gas Chromatography
Gas Chromatography (GC) has evolved into one of the most widely used tools for chemical analysis. When the majority of GC applications switched to higher performance capillary columns, techniques requiring in-oven column connections became much more challenging to implement. New tecnhnology of in-oven devices combine several new technologies to adhere to the stringent modern capillary chromatography requirement...
