Primary Reformer WHR coils were cleaned by dry ice blasting during annual shutdown. This measure will reduce consumption of NG. Total cost for the job is around 4.5 Lakh.
Urea plant: Installation of condensate pump with optimized head and capacity. Estimated power saving is 25.4 kW. Total cost of the scheme is 40.8 Lakh.
Boilers: Reduction in Radiation Losses by providing Thermal Insulation to uninsulated/damaged portions in the Boilers for reduction in Heat losses. By this measure, around 26.6 Tons per year Coal saving is anticipated.
Energy Saving Measures under implementation or planned for implementation:
Electrical System, Bharuch: Total power saving of 2,93,664 kWh has been planned by replacing old conventional light fittings with energy efficient LED fittings (total 1538 nos.). The estimated cost would be 46.8 Lakh.
ASGP: Replacing Syn gas by H2 rich feed gas of PSA in Reformer Feed. The scheme is under execution stage. Yearly estimated energy saving will be around 6673.7 Gcal.
Urea Plant: Conversion of Main Ammonia feed pump (P-1A/B/C) Torque Convertor to Variable Frequency Drive (VFD). Estimated power saving is 150 kW. Estimated cost of the Scheme is 1037 Lakh.
Installation of high efficiency Hydrolyzer Feed Pump by replacing existing old pump-motor set. This scheme is having power saving potential of 30 KW.
