Catalytic polymerization unit at the General Petroleum Corporation's refinery, ca.1940

Photograph of a catalytic polymerization unit at the General Petroleum Corporation's refinery, ca.1940. Metal beams criss-cross to form three levels on a tall, open-air, rectangular structure at center. Pipes can be seen along the sides of the structure, while five barrels are visible lined up on the ground to the right of the structure. A utility pole is visible at left, while a cylindrical tower can be seen in the right background.; Photoprint reads: "This new catzlytic polymerization unit at the Torrance (Calif.) refinery of the General Petroleum Corporation 'builds' 700 barrels of high quality gasoline daily out of what would otherwise be waste refinery gases. Over $400,000 was spent on the addition of this unit".

约1940年，通用石油公司（General Petroleum Corporation）炼油厂内的催化聚合装置（catalytic polymerization unit）照片。画面中央为一座高耸的露天矩形构筑物，金属横梁纵横交织，构成三层作业平台。该构筑物侧面敷设管道，其右侧地面上整齐排列着五个油桶。左侧可见一根电线杆，右侧背景中则矗立着一座圆柱形塔台；照片冲印件标注文字："这座全新的催化聚合装置位于通用石油公司加利福尼亚州托兰斯（Torrance）炼油厂，可将原本作为废料的炼油厂废气每日转化为700桶高品质汽油。该装置的加装耗资超40万美元。"
