As conventional oil and gas reserves diminish, focus has turned to unconventional sources such as remote offshore and the Arctic. In offshore operations, space for processing equipment is limited and therefore equipment footprint, chemical use, and wastes produced required are factors in the type of processing possible. Along with the approximately 15.5 million cubic meters of oil produced offshore Newfoundland and Labardor (NL) in 2011 approximately 4.5 billion cubic meters of gas was also recovered. 90% of this gas is re-injected, 8-9% used for fuel, and 1-2% flared. Them lack of space limits gas treating to dehydration and compression, however gas quality impacts the gas injection and utility infrastructure. Gas contaminants such as water, carbon dioxide, and hydrogen sulphide requires injection of hydrate control chemicals, specialized alloy for piping, and reduces gas injection or enhanced oil recovery effectiveness. Gas recovery for use on shore is determined by the feasibility of the various gas transport options which are in turn governed by gas quality to meet the standards for transport.The focus of this work is to develop gas processing systems capable of achieving gas quality while meeting the infrastructure/space limitations on the platforms. The underlying principle is green processing, where chemicals used are sustainably sourced, energy requirements and waste are minimized. The research is in two areas; gas treatment using a dual membrane contactor, and gas treatment via adsorbents derived from waste materials (e.g. fly ash and biochar). The advantage of these systems is very high surface area to volume/weight ratio and low operational complexity making them ideal for use in remote locations. The research will be comprehensive in addressing energy used/wastes generated of the proposed systems, from adsorbent/membrane sourcing to final re-use or disposal through life cycle analysis. Through the proposed research program, we will advance the design of offshore gas processing systems and develop systems suitable for use in harsh and remote locations

随着常规石油和天然气储量的减少，人们的注意力已经转向非常规资源，例如偏远的近海和北极。在海上作业中，加工设备的空间有限，因此设备占地面积、化学品使用和所需产生的废物是可能的加工类型的因素。 2011 年，除了纽芬兰和拉巴多 (NL) 近海生产的约 1550 万立方米石油外，还开采了约 45 亿立方米天然气。 90% 的气体被重新注入，8-9% 用于燃料，1-2% 燃烧。它们缺乏空间，限制了气体处理的脱水和压缩，但气体质量影响气体注入和公用设施基础设施。水、二氧化碳和硫化氢等气体污染物需要注入水合物控制化学品、管道专用合金，并减少气体注入或提高石油采收率。岸上使用的气体回收取决于各种气体运输方案的可行性，而这些方案又受气体质量的影响，以满足运输标准。这项工作的重点是开发能够实现气体质量的气体处理系统，同时满足平台上的基础设施/空间限制。基本原则是绿色加工，即使用可持续来源的化学品，最大限度地减少能源需求和废物。该研究分为两个领域；使用双膜接触器进行气体处理，以及通过源自废料（例如飞灰和生物炭）的吸附剂进行气体处理。这些系统的优点是表面积与体积/重量之比非常高，操作复杂性低，使其非常适合在偏远地区使用。该研究将全面解决拟议系统所使用的能源/产生的废物，从吸附剂/膜采购到通过生命周期分析的最终再利用或处置。通过拟议的研究计划，我们将推进海上天然气处理系统的设计，并开发适合在恶劣和偏远地区使用的系统
