HPA has a catalyst dense loading division focused on bringing a much needed and now required alternative to the Oil & Petrochemical Industry. HPA offers a catalyst dense loading method, designed by Chevron and modified by HPA, called the HYDROPAC®. The HYDROPAC® allows the sprinkling of catalyst in a continually uniform pattern at a rate slow enough to let each particle settle but fast enough for acceptable loading time. There are several dense loading technologies on the market, but few if any, that can match the HYDROPAC® in design and performance. read more
