Capital investment costs can be divided into two categories (1) costs that are independent of the location (Inside Battery Limits, ISBL), and (2) costs that are dependent on the location (Outside Battery Limits, OSBL). 

For the Equipment Safety Subindex the process plant area is divided into two different areas, which have different safety properties. The onsite area is the area where the raw materials are converted into the products. This is referred as the inside battery limits area (ISBL). This area is characterized by large number of equipment and piping located in a concentrated way in a small area. The rest of the plant is referred as the offsite or outside battery limits area (OSBL). The offsite area is characterized by large inventories of fluids, which are often flammable and/or toxic. The number of equipment in OSBL area is smaller but their size larger than in the ISBL area. The layout is much more scattered in OSBL than in ISBL which is to enhance safety. 

This is a multiplier , which when applied to the purchase prices of major pieces of chemical process equipment, provides an estimate of the installed cost of the chemical process. b ISBL, inside battery limit. c OSBL, outside battery limit. 

Inside battery limit (ISBL) is the limit of the processing facility and the equipment contained therein. 

To satisfy the increases in demand in the next decade, ethylene plant construction will have to continue at a brisk pace. Table II gives our estimates of plant growth and the inside battery limits (ISBL) capital investments required. An approximate 69 billion lbs/year increase in plant capacity must be installed in the period to meet the increase in demand. An additional 25 billion lbs will probably be installed to retire... 

The investment cost will be given, indicated as ISBL (inside battery limit plant, laboratories, process control system, etc.), OSBL (outside battery limit) or infrastructure costs. It is expected that the OSBL costs for a micro structured reactor plant will be a minor issue as here mainly costs for housing, cooling facilities, etc., are included. 

The input/output structure defines the material balance boundary of the flowsheet Often it is referred as the inside battery limit envelope. A golden rule requires that the total mass flow of all components entering the process must be equal with the total mass flow of all components leaving it. It should be kept in mind that the recycles affect only the internal process streams, but not the input/output material balance. 

Economics Investment, US Gulf Coast inside battery limits for the production of 80,000 tpy of LAB 1,000/tpy. 

Estimated inside battery limits (ISBL) costs based on unit processing 158,000 mtpy of BT reformate feedstock with 68 LV% aromatics (US Gulf Coast site in 2003). 

Economics The solvent used in the Sulfolane process exhibits higher selectivity and capacity for aromatics than any other commercial solvent. Using the Sulfalane process minimizes concern about trace nitrogen contamination that occurs with nitrogen-based solvents. Estimated inside battery limits (ISBL) costs based on a unit processing 158,000 mtpy of BT reformate feedstock with 68 LV% aromatics (US Gulf Coast site in 2003).

Economics Ethylene yields vary between 25%, 35%, 45% and 83% for gas oils, naphtha, LPG and ethane, respectively. Related specific energy consumption ranges from 6,000, 5,000, 4,000, 3,000 kcal/kg C2H4. Typical installation costs for a large-scale inside battery limit gas (naphtha) cracker on a Gulf Coast basis are 500 (750) U.S./ton of installed ethylene capacity.

Catalytic distillation essentially eliminates catalyst fouling because the fractionation removes heavy coke precursors from the catalyst zone before coke can form and foul the catalyst bed. The estimated ISBL (inside battery limits) capital cost for 35,000bpd CDHydro/CDHDS unit with 92% desulfurization is US 25 million, and the direct operating cost including utilities, catalyst, hydrogen, and octane replace-...
