| Summary: | Ammonium Chloride (NH4Cl) is chemicals material that is much used in the
chemical industries. Ammonium chloride is used as a raw material for the batteries
manufacture, cleaning solder for electronics industry, plywood glue, hardener snow,
fertilizer, and the material for alkylhydroxylamine nitroparaffin reduction.
NH4Cl production done by methatesis method (NH4)2SO4-NaCl were proceded
by a process of purification of salt to become pure grade NaCl. NaCl and (NH4)2SO4
is dissolved in water in a reactor at a temperature of 30°C and a pressure of 1 atm.
After exiting the reactor is formed NH4Cl solution and supersaturated solution of
Na2SO4 which later crystallized in the Crystallizer. NH4Cl plant is classified as low
risk due to plant operating conditions and the material used is safe for the
environment. The whole process is done in the room due to the nature of materials
that easily absorb water.
NH4Cl factory is planned to be constructed in Gresik, East Java with a total
area of ± 7.5 ha of land and required 225 labours. The plant was designed with the
capacity of 32,000 tons / year and operates continuously for 330 days / year.
Ammonium chloride to produce as much as 3,616.25 kg/h of fuel, needed fuel oil as
much as 1277.26 kg/h, the water needs of the river as much as 12,6905 m3/h,
electricity needs 1019.89 kW and the needs of a total of 16660.71 kg of steam/h.
Fixed capital is required $ 6,452,181.43 and Rp 215,931,928,424.65 and
working capital is required Rp 144,213,953,047.49, with profit before tax Rp
93,919,677,175.13 and Rp 46,959,838,587.57 after tax. From the calculation results
obtained by Return on Investment (ROI) before taxes 34.28% and 17.14% after tax,
Pay Out Time (POT) before tax 2.25 years and 3.68 years after tax, Break Even Point
(BEP) 49%. Shut Down Point (SDP) 28.13% and Discounted Cash Flow of Return
(DCFRR) 35.48%. Based on that NH4Cl plant is quite interesting to study further.
