Engineering approach optimizes process design, reduces costs for NGL facility upgrade

M. F. Khan and R. Riaz, Jacobs Zate, Al Khobar, Saudi Arabia In the present oil and gas market, companies may think twice before installing new equipment, even for necessary upgrades. Cost-effectiveness has become increasingly necessary. The role of the engineering contractor is critical to studying cost-reduction options during engineering design and budget allocation decisions.   In every NGL facility, a product chiller package (PCP) is installed to subcool NGL to compensate for the subsequent heat gain in loading and recirculation lines. Subcooling of NGL guarantees that product temperature specifications for ship loading are met (Tables 1 and 2). The loading system comprises stora
