Project objective
Assess whether two existing waste-gas streams can feed a new methanol unit, with the product returned to downstream chemical production.
Offered technologies / Process plants
Methanol production from waste gas
A concept for using hydrogen- and carbon-monoxide-rich gas to produce methanol. The solution links feed treatment, compression, catalytic synthesis, distillation and associated plant systems.
Operating context
The whole application matters.
The first step is to establish feed composition and variability and prepare a process simulation with material and energy balances. The proposed route includes compression and mixing, contaminant removal based on analysis, syngas adjustment, a synthesis loop with recycle, and two-stage methanol distillation. The need for reforming and CO shift is assessed against the specific feed composition and target yield.
Scope of the solution
- Basic engineering package: design basis, balances, process flow diagrams and P&IDs.
- Specifications for compressors, reactors, heat exchangers, columns, vessels, pumps and piping classes.
- Instrumentation, control, interlock and shutdown concepts, with electrical and utility interfaces.
- Unit layout, product storage and definition of tie-in points.
Engineering priorities
From operating need to design.
Supply interfaces
Composition, pressure, temperature and flow of each feed gas, including sulphur and other trace contaminants.
Engineering output
An agreed basic engineering package with balances, diagrams, datasheets and equipment lists.
Before engineering
Inputs that matter.
- Which gas streams are available, and how do their composition and flow vary?
- What annual output and product specification are required?
- Which utilities, space and tie-ins are available at the existing site?
- Does the enquiry cover a study, basic engineering, individual equipment or a subsequent supply package?
Agreed with the proposal
Outputs and acceptance.
- An agreed basic engineering package with balances, diagrams, datasheets and equipment lists.
- Defined supply boundaries and inputs for detailed design, equipment selection and agreement of performance guarantees.
The actual scope and acceptance criteria depend on the application and contract.
