Feasibility / Cost Estimate for AMMONIA acid plant
March 2017
Davi EPC own order from tolic , UK for Engineering, procurement, construction, of ammonia plant.
DAVI EPC provides Cost Estimate and Feasibility Study Services to clients. The typical list of deliverables for the Feasibility Study is as follows:
Design Basis: The client will participate in establishing a basis for the plant design. CEP will establish capacity, feedstock characteristics, product quality and plot space. A questionnaire will be required to get a better understanding of power supply and general site conditions that may affect the design
Preliminary Process Flow Sheets: The drawings will show major equipment, pumps, exchangers, vessels, etc.
Preliminary Emissions Information: Approximate values for flow rates and composition of effluents will be provided. This information may be sufficient to initiate discussions with local permitting agencies
Equipment List: Major equipment items will be identified and preliminary equipment sizing will be provided. These are subject to change after detailed simulation models are developed during Basic Engineering.
Cost Estimate:
-
Estimate Basis - Define procurement preferences and/or limitations (i.e. UK, EU, India, Eastern Europe supply)
-
Pricing for Major Equipment
-
Financial Model: A financial model will be developed for the project to facilitate the client's evaluation of alternatives and sensitivities. This will include gross margin and internal rate of return calculations.

PROCUREMENT ENGINEERING FOR ACETIC ACID PLANT
Davi EPC cross functional Procurement engineering team that supports customers in purchase of engineered commodities and package units for Process Plants from the global market. The team has extensive understanding of the global supply base and procurement best practices, apart from good fundamental and technical knowledge in various engineering disciplines.
Starting with understanding general procurement specifications, the team initially prepares a technical procurement package. Based on the specifications, we identify suitable suppliers from an Approved Vendor List (AVL) or from a global supply base, considering the key vendor qualification criteria that the customer may have. Based on these criteria, technical bids are requested from the vendors, which go through a detailed Technical Bid Analysis (TBA) by our team. Following this analysis and a technical bid evaluation, we prepare final purchase specifications, which are considered as Issued for Purchase (IFP) documentation.
The Enventure team also assists clients during negotiations, and issues of purchase orders. Vendor drawings and documentations also always go through various stages of review and approval by our procurement engineering team.
Pre-Order:
• Assist in Finalization of Vendor List
• Preparation of Technical Procurement Package
• Technical Bid Analysis (TBA)
• Preparation of Purchase Specifications
Post-Order:
• Coordination with Vendors for Production Schedule
• Review and Approval of Quality Plans
• Finalization of ITPs
• Follow up and Approval of Vendor documents for Fabrication, Inspection and Dispatch
• Resolution of Technical Clarifications from Vendors
