Abstract: A process and apparatus for hydroprocessing a biorenewable feedstock involves an advantageous metallurgy. The biorenewable feed stream is hydrotreated in a hydrotreating reactor comprising a stainless steel having a composition of at least about 2 wt-% molybdenum which is sufficiently resistant to acidic corrosion. The hydrotreated biorenewable stream is hydroisomerized in a hydroisomerization reactor comprising a stainless steel having a composition of less than about 2 wt-% molybdenum. Most of the free fatty acids are deoxygenated in the hydrotreating reactor to make water, thus avoiding exposure of downstream equipment to acid attack. The stainless steel of said hydrotreating reactor may have a composition of no more than about 0.02 wt-% carbon.

Abstract: A process of producing a sweetened liquid hydrocarbon stream. In order to prevent the forming of acid species in a sweetening zone, a oxygenate removal zone is disposed upstream of the sweetening zone. The oxygenate removal zone may comprise a water wash or an adsorbent zone, including a regenerable adsorbent. The sweetened stream is formed from a least a portion of liquid natural gas stream which may be scrubbed free of hydrogen sulfide and dehydrated before passing to the oxygenate removal zone.

Abstract translation: 生产甜化液态烃流的方法。 为了防止在甜味区域中形成酸性物质，将氧合物去除区域设置在甜味区域的上游。 含氧化合物去除区可以包括水洗或吸附区，包括可再生吸附剂。 该甜味物流由液态天然气流的至少一部分形成，其可以在没有硫化氢的情况下被洗涤并在进入含氧化合物去除区之前脱水。
