Process design for energy efficient, economically feasible, environmentally safe methyl chloride production process plant: Chlorination of methane route

Methyl chloride is the starting raw material for chloromethanes and demand chloromethane increasing steadily in world market. Continuous improvement product quality, reducing cost, improving operation efficiency, minimizing environmental emissions, enhancing process plant safety are some of challenges or constraints facing by industry. In this research work, an attempt has been made to address these using systems engineering. As a first step, simulation model designed conceptually Aspen HYSYS V11 production 99.9 % pure methyl from methane chlorination route. Energy analysis performed effective utilization utilities adding one new heat exchanger. This modification reduced utility cost 31.17 recovered 13028 kW energy with payback period 0.8759 years. savings 3.26 %. Heat integration greenhouse gas emissions 16.5 Process improved depressurization studies. Safety calculations storage tank protection used product. Sizing valves vent off excess vapor through pressure protect equipment against overpressure scenarios. design engineers can use methodology developed study energy-efficient, economically feasible, environmentally safe chemical plants.
