Technical Paper: Case Study Of Effects Of Bicine In Co₂ Only Amine Treater Service

Abstract
An Eco-Tec amine purification unit (AmiPur™) was installed in a Vintage Petroleum facility located in Fillmore, Ventura County, California to reduce bicine concentration in DEA solution used for CO₂ removal from natural gas.

Vintage Petroleum Plant Background
The plant is designed to treat 6.5 million SCF per day of natural gas containing 20 mol % CO2 and only trace amounts of H₂S. The plant uses 30 w/w% DEA circulating at 150 gpm with total inventory of 15,000 USG. The plant started its operation in April 2003. The plant effectively reduces the inlet CO2 content currently from 12 mol % to about .2 mol %.
