Abstract :
Currently, less than 0.2% of the total
methanol production capacity is from renewable sources.
In this study, we designed and modelled a methanol
production plant. The plant used 25,882.52mt per annum
of wood to produce 16,000mt of methanol per annum.
Details of the plant including a process flow diagram
with a material flow stream table have been discussed. A
preliminary control system and the resulting piping and
instrumentation diagram were developed. Oron local
government area of Akwa Ibom state, Nigeria was
chosen as a suitable location for the plant and the plant
layout was carefully mapped out taking into
consideration the safety measures, environmental
influence and the hazard factors involved. Detailed
safety analysis was carried out on the plant; the
environmental analysis, occupational health and safety
analysis, hazard and operability studies and general
plant safety have also been discussed. To understand the
degree of hazard the plant will pose; the fire and
explosive index was calculated for the major equipment
and the overall fire and explosive index of 159 was
obtained indicating that the degree of hazard is severe.
At a total investment cost of 6.3 million USD, the plant
realized a net profit of 3.1 million USD.
