§ Mr. Skeetasked the Secretary of State for Energy whether it is economical to adjust naphtha crackers to make alternative feeds such as gas oil, propane and butane.
§ Mr. GrayOlefin crackers designed to process naphtha have in some cases been adapted to accommodate other feedstocks such as gas oil, butane, propane and even ethane. The economics of such a conversion depend on the capital costs involved; the cost and availability of feedstocks; operating costs; and the value and mixture of the total yield of 317W products. Yields will vary accordingly to the feedstock used.
