Complete a technical (chemical engineering) assessment of options for storing gas

We would like to complete a technical assessment of options for storing gas. Gas Types: 1. Natural gas (pipeline specification) 2. WCMG – Lower levels of CH4, may contain O2 3. LFG – may contain small amounts of O2 Gas Storage Options: 1. Low Pressure Options (i.e. Bladder systems, where gas clean-up will be minimal) 2. Medium Pressure Options (i.e. Line Pack in a pipe - will require gas clean-up) 3. High Pressure Options (i.e. CNG – will require gas clean-up) Outputs: 1. Applying an incremental size that makes sense (maybe equivalent to 1MW or 2MW for 1 hr as an example – TBC) the freelancer will provide: a. High level CAPEX and OPEX for each option b. Strengths and Weaknesses c. Lead Time d. Risks - Permitting / Approval issues assuming construction in Queensland Australia. 2. This information will then be compiled to produce a list of probable solutions. We will use this information to complete a more thorough commercial and technical assessment of the different options. We will provide you typical gas compositions for WCMG and LFG. A background in chemical/process engineering and familiarity with the above technologies is expected.
