Attachment 3 - Equipment List Addendum.pdf

Equipment Addendum The equipment addendum explains how the equipment will be used in the pilot plant high bay space at NREL. There are three groups of equipment. The first is process equipment, the second is analytical equipment, and the third is utility support equipment. In addition, there is a small scope related to tanks that are NREL property. Modifications on these tanks are necessary to meet electrical classification needs. For more information regarding the process equipment, please see the process design basis that are a part of this package. Those are meant to serve as the Front End Loading (FEL) 1 packages for the unit operations.

One important note is that the budget is fixed for this project. The scope will change depending on the budget estimates received.

Glossary of Acronyms:

VOC – volatile organic compound(s) psig – pounds per square inch gauge

ISO – international organization of standards gal - gallon kW – kilowatt Deg C – degree centigrade hr - hour cm - centimeter Deg F – degree fahrenheit ft - feet L - liter µS - microsiemens SCF – standard cubic feet

Process Equipment/Unit Operations:

The following process equipment FEL 1 was completed by NREL process engineers. The budget will not accommodate all outlined unit operations. For this project, NREL foresees changing scope to accommodate a fixed budget.

2 Reactor Hydrotreater Unit Stripper – Distillation Column (2 of them) 2 Reactor Isomerization Unit Ion Exchange Solvent Extraction – centrifuge based Anaerobic Digestor Liquid Liquid Extraction Absorber Adsorptions Wiped Film Evaporator Decanter Microfiltration & Ultrafiltration Unit

The process equipment should be constructed so that the equipment can be easily reconfigured to pipe together various equipment in new ways to accomplish research goals. For instance, for the hydrotreating unit, the reactors should be their own “process module” so that if only one reactor is needed with the flash drums and a distillation column downstream, it is easily reconfigured within one month and commissioned. Feed tanks and pumps are separate from this scope as are product tanks and pumps. Those are outlined below.

Analytical Equipment:

The unit operations for this renovated pilot plant facility will need online and offline analytical equipment to support process development. A large part of the goals associated with the project is to ensure complete heat and material balances. The online analytical machines will NOT be tied to one type specific process equipment and could be recalibrated and moved to where it is needed.

NREL chemists will handle the recalibration and purchase of additional material when or if the need arises.

If the budget exceeds $2.5 million for this equipment, NREL will prioritize the analytical machinery necessary and the scope will be cut.

Tankage

There are six jacketed and agitated tanks that NREL wants to re-use as feed and product storage tanks in the small tank farm within the pilot plant. In order to have these tanks in working order, the following needs to be added or replaced with Class 1 Division 2 electrically classified components:

• Level indication – board mounted and local

• Pressure indication – board mounted and local

• Nitrogen pressure control valve for blanketing

• Electrically classified agitators (size varies) and motors

• Temperature indication – board mounted and local

• Temperature control valves for jacketed material circulation

Along with the tankage, feed pumps are also necessary. The following pumps will need their own skids/carts. Spillbacks with a feed control valve are also necessary for each centrifugal pump.

Generally positive displacement pumps are more common at NREL, however if the cost of a reciprocating pump is 33% higher than a centrifugal pump, a centrifugal pump is acceptable.

Utility Equipment:

Utilities will be supplied and/or disposed of by various pieces of equipment.

Title Description & Assumptions Equipment List Thermal Oxidizer Flammable offgases, relief vents, and sample vents are directed to a central header that is swept towards a burner. The burner is vented outside, to safely dispose of the vapors/gases. The thermal oxidizer must be able to handle 100% hydrogen production from 450 kW hydrogen electrolyzation. This produces approximately 3,360 SCF/hr of saturated hydrogen. Natural gas is available for the burner(s).

Piping, nitrogen sweep hookups, drops every two feet, a thermal oxidizer capable of 100% hydrogen fuel, a knockout pot and pump.

Instrumentation for flow measurement, pressure, and temperature.

Vent Gas Scrubber

Gases/vapors routed to scrubber when containing dihydrogen sulfide, other acids, foul smelling materials, etc so that those can be scrubbed with the appropriate materials to decrease the concentration being routed to the thermal oxidizer.

Vessel, random packing, level instrumentation, pumps, internal distributors, pressure instrumentation, flow control valves, piping, tank for scrubbing material, etc.

Deionized Water Production Skid

The deionized water skid needs to supply the hydrogen electrolyzer with enough water for 450 kW processing capabilities.

The water conductivity needs to be maintained under 1400 µS/cm. Peak consumption of Deionized water is 540 L/hr. The feed water should be provided at a pressure between 30 psig and 90 psig and a temperature between 15 to 25 deg C.

Deionized water skid designed to meet the criteria listed and water storage tank for 100 gallons.

Waste Water Stripper

Waste water needs to be collected from the North High Bay because it cannot be mixed with the current waste water system in place at the IBRF pilot plant. They need to remain separated because of hydrocarbon possibly being in the material processed in the North High Bay. Volatile organic
