The chemist works in test tubes and Parr bombs with very small quantities of reactants and products (e.g., 100 ml), usually running “batch”, constant-temperature experiments. Reactants are placed in a small container in a constant temperature bath. A catalyst is added and the reactions proceed with time. Samples are taken at appropriate intervals to follow the consumption of the reactants and the production of products as time progresses. 化学工程师经典的角色是把化学家在实验室里的发现拿来并发展成为能赚钱的、商业规模的化学过程。化学家用少量的反应物在试管和派式氧弹中反应相应得到少量的生成物，所进行的通常是间歇性的恒温下的实验，反应物放在很小的置于恒温水槽的容器中，加点催化剂，反应继续进行，随时间推移，反应物被消耗，并有生成物产生，产物在合适的间歇时间获得。 By contrast, the chemical engineer typically works with much larger quantities of material and with very large (and expensive) equipment. Reactors can hold 1,000 gallons to 10,000 gallons or more. Distillation columns can be over 100 feet high and 10 to 30 feet in diameter. The capital investment for one process unit in a chemical plant may exceed $100 million! 与之相比，化学工程师通常面对的是数量多得多的物质和庞大的（昂贵的）设备。反应器可以容纳1000 到10,000加仑甚至更多。蒸馏塔有100英尺多高，直径10到30英尺。化工厂一个单元流程的投资可能超过1亿美元。 The chemical engineer is often involved in “scaling up” a chemist-developed small-scale reactor and separation system to a very large commercial plant. The chemical engineer must work closely with the chemist in order to understand thoroughly the chemistry involved in the process and to make sure that the chemist gets the reaction kinetic data and the physical property data needed to design, operate, and optimize the process. This is why the chemical engineering curriculum contains so many chemistry courses. 在把化学家研制的小型反应器及分离系统“放大”到很大的商业化车间时，通常需要化学工程师的参与。为了彻底了解过程中的化学反应，化学工程师必须与化学家密切合作以确保能得到所需要的反应的动力学性质和物理性质参数以进行设计、运转和优选流程。这就是为什么化工课程要包括那么多的化学类课程的原因。 The chemical engineer must also work closely with mechanical, electrical, civil, and metallurgical engineers in order to design and operate the physical equipment in a plant--the reactors, tanks, distillation columns, heat exchangers, pumps, compressors, Control and instrumentation devices, and so on. One big item that is always on such an equipment list is piping. One of the most impressive features f a typical chemical plant is the tremendous number of pipes running all over the site, literally hundreds of miles in many plants. These pipes transfer process materials (gases and liquids) into and out of the plant. They also carry utilities (steam, cooling water, air, nitrogen, and refrigerant) to the process units. 化学工程师还必须与机械、电子、土木建筑和冶金工程师密切协作以设计和操作工厂的机械设备—反应器、槽、蒸馏塔、热交换器、泵、压缩机、控制器和仪器设备等等。在这张设备 rass-roots gover nance a ccording t o law is an important foundati on for promoti ng the construction of rule of law, but a lso t he most basi c deve lopme nt envir onment.
