Q2: Where do customers get appropriate shipping documents?
A: Customers are able to download address label, hazardous shipping label and SDS from the HARP Tracker program. Placards are available at:http://www.labelmaster.com/store/scripts/view-product.cfm?product=ZEZ41760

Q3: What is the typical concentration of sulfuric acid to charge into a scrubber system?
A: Typically customers should initially charge their scrubbers with 40% sulfuric acid solution in order to obtain the best results in amine reclamation. NOTE: Scrubber systems vary therefore always follow the instructions from the manufacturer of your particular system.

Q4: How does a customer know if they have the appropriate concentration of amine in their scrubber solution?
A: Amine content can be tracked as a function of pH. The customer should measure the pH of their system on a regular basis to ensure that their scrubber solution is effective in removing free amine. Assuming the customer initially charges their scrubber solution with 40% sulfuric acid; the acid solution efficiency will begin to degrade after reaching a pH of 3.0 and require replacement. Target pH for exchanging scrubber solution is 4.0 (+/- 1), which will give best yield during reclamation. See our Amine Scrubber General Design & Operating Principles presentation.

Q5: How does the customer know that their scrubber solution is still actively binding amines?
A: Assuming the customer is initially charging their scrubber with 40% sulfuric acid by measuring pH they can assume that when the pH rises to 3.0 that the free sulfuric acid level is near 5% and therefore not as effective in capturing amine gas.

Q6: What happens if the customer scrubber solution sample does not meet the requirements for recovery?
A: There are still options available if the sample analysis determines that the minimum requirements of pH, recoverable amines, and free sulfuric acid content are not met. Chemtech will work with the customer to determine what steps can be applied to bring the material into specification as well as suggest other alternatives where applicable.

Q7: What should a customer do if they experience any functional problems with their cylinders, such as damage or leaking?
A: If a customer has any issues with a cylinder they should immediately contact the HA International Environmental Health and Safety Team (Jeff Krause 630-575-5705).

Q8: Can a customer send in totes of scrubber solution to Chemtech Services without pre-approval?
A: No, a sample of scrubber solution from each bulk tote is required to be sent to Chemtech Services for analysis and approval before shipping the scrubber solution in totes.

Q9: Do customers have to use the sample bottles provided through HARP for sending samples of spent scrubber solution to Chemtech for analysis.
A: No, customers do not have to use sample bottles from the program, but they are encouraged to use the provided bottles which are free of charge.

Q10: How do I receive my discount on purchased amines?
A: Enroll in the program at www.ha-international.com and a sales representative will contact you.  You will be entered into the system and your pricing discount will be applied off of your current price.  If you are a new customer, the pricing discount will be applied off of your quoted price.  In order to continue receiving your discount you must submit scrubber solution for reclamation.  If after joining the program you are found to be inactive for more than 90 days by not submitting scrubber solution for reclamation, you will be contacted by your HAI sales representative who will confirm if you wish to continue participating in the program.

Q11: Who pays for the freight on returning totes of spent scrubber solution to Chemtech Services?
A: The customer is responsible for freight charges on spent scrubber solution.

Q12: What are the Certificate of Analysis and Certificate of Reclamation?
A: The Certificate of Analysis is the customer record of their sample analysis.  The Certificate of Reclamation is the customer’s record and proof that their amine sulphate solution was properly recovered.
