Area of Improvement:Smoke tube boiler of 10TPH, operating at 17.5 barg was used for generating steam for process requirement. The fuel used for boiler operation was Natural gas. Observation:Boiler was in operation with conventional economizer. De-aerator with 105 Deg C of feed water was fed to economizer and flue gas of 250 Deg C enters …
Area of Improvement: 350 TR Screw chiller, with refrigerant as R134a was in operation. Chiller inlet and outlet temperature was designed for 12 deg C and 7 Deg C. variation in cooling water temperature was from 22 deg C to 32 deg C. Cooling tower water treatment program was well maintained. Condenser cleaning procedure was …
Case Study: Inline condenser cleaning system for 350 TR chiller. Read More »
Area of Improvement: In a process plant 60% of condensate is recovered at approx 90 Deg C, remaining condensate was contaminated as it is being used in steam ejectors, direct heating in process and multi utility reactor therefore it was not recovered. Observation: 40% of feed water of approx 12 KL/hr was fed to deareator …
Area of Improvement: Approx 5 TPH of condensate at 2.5 barg pressure was collected and transferred to boiler for condensate and heat recovery with the use of PPPU “Pressurized powered pumping unit”. A flash vessel was installed to collect flash generated though condensate at .5barg pressure and was utilized for hot water generation. Observation: As …
Area of Improvement: Steam was being produced from 2 different boilers of 20TPH at 17 barg pressure in a chemical process industry. Average load of site was 30TPH, High pressure steam of 17 barg was transferred to different user blocks for end use. Steam was majorly used for process heating at 3 barg pressure. Observation: …
