·The power plant is supplied by several production wells Some of them produce mainly steam two phase and water This study however only focus on twoa phase production well which supplies fluid to a separation system and brine pipeline where severe silica scale problem was encountered Brine water discharged from this production well is a
·Most can still use silica sand with a SiO2 content of % but impurities can be as high as 200 ppm Previously Indonesian President Joko Widodo Jokowi firmly prohibited the export of silica sand or quartz sand According to President Jokowi silica or quartz sand has 60 000 derivatives with significant added value
·The main source of Mn in raw materials for SiMn production is Mn ore and Mn rich slag from the high carbon FeMn production The amount of slag per tonne of SiMn metal is mainly determined by the ore/slag ratio Increasing share of FeMn slag at expense of Mn ore will lead to larger slag/metal ratio in the SiMn process High volume of slag leads to an increased
The silica reduction proceeds to equilibrium according to either of the following reactions the second being applicable when the silicon content of the metal at 1600°C exceeds about 17 % in Mn Si Csat alloys At unit activity of C respective SiC and of CO we have Graphite stable a Si = K T 5 ⋅ a SiO2 Silicon carbide stable a Si = 3 K T
